"I'm a selfish king. So I want to protect the forest, my people, Diane, everything!"
King「キング」 is a member of the Seven Deadly Sins and is known as the Grizzly's Sin of Sloth. His real name is Fairy King Harlequin「妖精王ハーレクイン Yōsei-Ō Hārekuin」 for he protects the Fairy King's Forest and the rest of the Fairy Realm. His Sacred Treasure is the Spirit Spear Chastiefol, which he uses in conjunction with his inherent power, Disaster.
King's fairy form resembles a young boy with short brown hair, a high forehead, thin eyebrows, and brown eyes. He wears a long orange and aqua sweatshirt with a hood and navy blue sleeves, quarter-length navy blue pants, and short boots wieth large buttons matching his hoodie. He also carries a green leopard pattern pillow which is actually a transformation of his spear Chastiefol. Despite being a fairy, he has no visible wings.
In his human form, he looks almost exactly like his wanted poster; large, fat and more ragged, perhaps hinting at how humans look to fairies. He wears an enlarged version of the clothes he wears as a fairy, though he can freely change the clothes he wears in this form.
Ten years ago, he wore full-body light green armor with a helmet that fits the size of his human form. King's wanted poster depicts him as a big man with short hair, sideburns, a button nose, and a sneer. His Seven Deadly Sins Grizzly symbol is located just above his left ankle, on the outer side of his lower leg.
In his first appearance, he is shown to be an ally to the Holy Knights and is willing to wipe out anyone who gets in his way along with the person he is after. Since he is the Sin of Sloth, he is shown as somewhat lazy, preferring to levitate in most occasions. In the past, he was shown to be a compassionate character who returned stuffed animals stolen by Ban to children. Furthermore, it appears that he is an emotional person who cries easily.King has trouble admitting his affection for Diane. Although he enjoys being with Meliodas and Diane, he could not bring himself to express it. He cares deeply for his sister, Elaine, as shown when he was willing to take revenge for her death by "killing" Ban.
King is also shown to have a caring side. He helps the Seven Deadly Sins in their battle against the Holy knights, although he claims it is merely for Diane. Despite being the Sin of Sloth, he is hard working and serious at times. When King joins the group, he starts to act like the only rational one in the group, and questions his teammates' erratic and slightly insane actions, such as their nonchalance about losing their sacred treasures. When forced to do something he dislikes, King can easily be motivated if it will make Diane happy.Despite King's kind personality, he is not against killing someone, if pushed to his limits. King was willing to kill Guila and Jericho if they continued to attack him, but was unable to after Helbram saved the two.
700 years ago
Seven hundred years ago, King was the ruler and guardian of the Fairy King's Forest; a country set on the border between the Fairy and Human realms. His spear, Chastiefol, was made from the Sacred Tree placed in its center. King used to live with Elaine along with other Fairies, keeping up the peace between them and the humans. During his time protecting the forest, King and Helbram were best friends. But unlike Helbram, King found no interest in humans and cautioned Helbram not to trust them. However, Helbram and his group went out of the forest to see the human world where they met a group of human travelers who promised to give them items in exchange for information about the Fairy World. However it was revealed that the humans were only after their wings, which could be sold for a lot of money as it was believed to extend a person's lifespan. King then went out of the forest to save his friends despite Elaine's efforts to stop him, telling her to stay and protect the forest. After finding the dead bodies of the Fairies, King stumbled upon a tall, armored human wearing an eye patch named Aldrich who attacked him from the back, ending up nearly killing him, until he was saved by a young Diane. Due to his injuries, King ended up forgetting about his life as a Fairy King and spent his time playing with and protecting Diane.
Diane later met a stranger who offered them soup, despite them being a fairy and a giant. Feeling uneasy with the old man, King told Diane to be cautious around humans. When Diane came down with a fever, he was sent into panic due to the fairies' lack of understanding on disease and sickness. However, Diane stopped him, telling him to not leave her side since she was always lonely. The old man who gave them food found them and offered some herbs for Diane to feel better. At this point, King realized that a human's time passed much faster than the other races, as the old man that he had met before had aged several decades since the last time he had given them soup. As soon as Diane got better, they ended up playing tag with each other. He told her that if she caught him, he would grant her a wish. Diane took it seriously and caught him, but ended up getting her clothes ripped, leaving her naked, much to his surprise. He decided to make her new clothes and went to the old man's place, only to find more towns built there, and that the old man had a grandchild now. After leaving the forest, he told Diane about marriage between two humans who love each other.
Diane asked if King loves her, to which the latter shyly nodded. Diane then asked him if he would always love her and stay by her side, which made him blush harder. Later that night, he finally remembered his identity and found out that the village close by is on fire. He told Diane to sit back and hurriedly went to the village, only to find out that everyone died with their backs slashed. King found the man who killed him years ago, and was shocked to see him still alive. He then realized that it was Helbram using the identity of the person who hunted down the fairies for their wings. He got back up and decided to end Helbram's rage to humans, killing him in the end. King then went back to Diane to erase her memories of him, fearing that he will be unable to protect anyone any more. King was then captured by unknown Holy Knights for the crime of "Sloth" as he was a king, and was unaware of Helbram's mass murder of humans, and turning a blind eye. Unaware at the time, one of those Holy Knights was Meliodas, with whom he would be properly introduced to after joining the Seven Deadly Sins. Additionally, Due to his imprisonment, King was unable to return to the Fairy King's Forest, and was absent during the events that lead to the Destruction of the Forest and the death of his sister Elaine. Because of his absence, his own people began to resent and eventually hate him, overall ending his reign as their king.
15 years ago
King's sin eventually led him to become a member of the Seven Deadly Sins when King Liones formed the group. Despite being a former king, he was not assigned the role of the leader.
A long time ago, Ban went through a phase of collecting stuffed animals. He went around stealing every stuffed animal in the kingdom, thinking that he wouldn't be cursed if he did such a small deed as he worked hard as a knight. Immediately, King grew angry at Ban, complaining that the little children throughout town were crying. Whilst Ban finally grew satisfied and fell asleep, King silently returned all of the stuffed toys to the children. Since then, King follows Ban wherever he goes to prevent him from causing trouble, giving other people an impression that they were the unlikely "dynamic" duo.
12 years ago
King and his teammates participated in a mission to wipe out a group of vampires at the castle of Edinburg. During the attack, King was partnered with Diane and confronted the two Vampires, Mod and Ganne, however, due to Ban, who was very drunk, and had deliberately used Snatch to steal all of his and Diane's strength as they were fighting, they were both struggling very hard to defeat them. Fortunately, they were saved by Gowther who had made the vampires believe he was a part of their family and had the two vampires attack and kill one another. Diane and King were then upset over Gowther for not coming sooner, who justified his actions by saying that he wanted to make it exciting.
Some time later, after the training, King accompanied Ban to a bar where he angrily glared at the immortal who passed out drinking while Meliodas was talking to Hendrickson and Dreyfus. At some point in time, he and his fellow Sins met up with King Liones who was with young Elizabeth. King did not recognize her until Gowther revealed her identity ten years later.
10 years ago
At the day of the betrayal, King and the rest of his teammates were summoned by Great Holy Knight Zaratras to meet with him at the castle. While walking with his fellow members, he reminded his captain, Meliodas, that he is always drinking when the latter mentioned that they should have attended the National Foundation Festival. They entered the room together and saw a murdered Zaratras, much to everyone's surprise. King obeyed Meliodas's last order to separate and hide until they can regroup.
Ten years ago, after the incident, King went back to his hometown to see his old family and friends. He discovered that a bandit had stolen the hidden treasure, the Fountain of Youth, and had killed the Guardian Saint, who was his sister. King later found out that it was Ban who had killed his sister and decided to take revenge on him by joining the Holy Knights.
After Meliodas, Elizabeth, Diane, and Ban escaped the Baste Dungeon, a young boy is seen with the Grizzly symbol near his left ankle, floating in the air whilst watching the shooting stars in the sky from a window.
King is looking out of the window when Gilthunder comes in and tells him that Ban has joined up with Meliodas and Diane. He then wonders why they decided to move. Gilthunder reassures King's loyalty to the kingdom, to which the latter coldly replies that he has his own ways of doing things. Suddenly, a Black Hound, named Oslo, enters the house and King welcomes it back. He asks if it had found Meliodas and the others, mysteriously understanding what it says. He then notices something in its mouth and pulls out two Holy Knights crests, whilst telling Gilthunder that the rest of the Holy Knights better stay away or he will wipe them away along with his enemies. Later, he appears before Ban and delivers a surprise attack by stabbing him in the chest. When Ban asks who he is, he replies that it is not important and quickly pierces his spear completely through Ban. Acknowledging the fact that Ban is confused by who he is, King reveals that Ban has killed the saint of the Fountain of Youth to obtain immortality. Immediately after hearing King stating his sin, Ban quickly sends Ellen and her brother away, and engages in a battle.King swiftly hovers towards Ban, attempting to pierce him again with the spear, but fails.
Before Ban can return with an attack, King immediately uses his levitation abilities to perform the technique, Bumblebee. Despite the simultaneous strikes, Ban still continues to dodge all of the attacks. Once again, the attack fails, forcing the impatient Ban to activate his ability Snatch. Just before he can activate it, Meliodas arrives and intervenes in the battle. Diane and Meliodas immediately recognize King, while Ban is surprised and dumbfounded. Despite Diane being happy to meet him, he quickly flies away without saying a word. After escaping, he continues to watch over the rest from afar, whilst complaining that he made it appear as if he ran away. He then comments on how cute Diane was and how it is almost impossible that Meliodas still looked the same. Finally, he remembers Ban's sin in the Fairy King Forest, and exclaims that Ban is fooling them. Out of the blue, Oslo barks at him, telling him that the group has moved to the edge of the town. A subtle wind whips up all the petal on the flower field, and the characters are all teleported to the Capital of the Dead. Noticing that Ban began chasing a mysterious figure, King quickly follows, wondering how they were able to enter the Capital. 
While continuing to chase Ban, King provokes him. The former tries to attack the latter, but fails. Noticing that King is able to dodge with ease, Ban finally acknowledges the fact that he is the real King and begins to fight more seriously. King uses his pillow as a decoy, cushioning Ban's punch and dodging quickly. Stating that he does not desire to reunite with Ban in such a situation, King narrates how he came to discover his hometown burned to the ground and the death of his sister.  His pillow then transforms into a form of a giant stuffed bear, immobilizing Ban, exclaiming that the guardian saint whom Ban killed was his sister. When Ban, in response, declares that he is immortal and can not be killed, he uses Chastiefol's Form Three, Fossilization that can petrify anything it impales. Ban's skin around the impaled area is shown to have petrified.
After Ban's body completely solidifies, King starts to move away, but notices a sphere of light appearing in front of Ban. King is then shocked when he realizes that it is actually Elaine. Confused, he sees Elaine kissing Ban and undoing the petrifaction. He asks why Ban can see Elaine whilst he can not, revealing his jealousy and disconcert. When he hears Elaine's voice, he asks to let him see her. King then questions whether Elaine is still mad at him for abandoning her and isolating for many years. However, he exclaims that there is no reason to save Ban, because he took everything from her. Angered, King asks what Ban is doing to his sister, only to hear Ban saying that he will make her his. King is left behind by Ban who heads out to assist Meliodas and Diane fighting against Guila. King continues to ask Elaine why she forgave Ban and not him, but Elaine simply replies that he left her alone for over 700 years, whereas Ban gave her renewed happiness in just seven days. Before King could say anything else, Elizabeth and Hawk arrive. He then asks about their identities, so Elizabeth and Hawk introduced themselves as Meliodas's traveling companions. Elizabeth tells him that a Holy Knight has suddenly appeared and is fighting against Meliodas and Diane, who in response, asks her whether she came to seek his help. Surprisingly, Elizabeth bravely tells him to run away instead, while trying borrow his spear to fight against Guila. Feeling inspired by Elizabeth's bravery, King heads to the battlefield.
During the fight, King suddenly appears behind and thrusts his spear through Ban to attack Guila. Ban asks him why he is there, to which he replies by saying that he is there to help Meliodas and Diane. Guila then blasts herself free and says that King's betrayal was expected. King then easily defends against Guila's next attack. When Guila confirms that she wants all four to attack her, he confidently insists that he will deal with her alone. He then easily puts Guila on the run by having his spear chase her. After Guila used Brilliant Detonation, King uses his spear's Form Five, Increase to defeat her technique and strike her down.
King then turns away, but Guila gets out of the rubble and attacks him. He is saved by Meliodas' Full Counter and notices that Guila's presence is gone. Afterwards, King, along with the rest, are rejected by the Capital, which Elaine thanks him for protecting Ban before they leave. When they return to the living world, they see how Guila got to the Capital of the Dead. He then volunteers to petrify her, but Meliodas insists that he will handle this.
Later, when everyone is eating fish, King asks Diane if she is okay, which the latter denies. Ban then exclaims that she is faking it, which he disagrees and defends. King then asks who Elizabeth is and Meliodas introduces her as the princess of the Liones Kingdom. King is shocked and turns into his former form. King then properly introduces himself. He feels exhausted for maintaining his human form, and explains that it requires a lot of concentration. King then almost gets into an argument with Ban, but Meliodas stops them. Elizabeth compliments him on his fight against Guila, to which he accepts and explains that he is indeed powerful because of his sacred treasure. He then says that the Holy Knight had no chance against the other three if they had their treasures with them. He then shifts his attention to his fellow members and asks them what happened to their sacred treasure, and is shocked to know the stories.
King yells at them when he hears how they lost their sacred treasures, which was given to them by a king (except Diane because he likes her), but Hawk asks him why it is such a big problem. King explains it by using the lake as a sin's power, telling him that if they used a sacred treasures, they can carry a whole house of water as power. King then says that it would be pointless to argue and they should find them while searching for the other members. The next day, King, Meliodas and Elizabeth go out to find information leaving Ban and Diane at the Boar Hat to house it. While walking, everyone is looking at them and to the group's surprise, they see that Elizabeth has gained a wanted poster.
The town realizes this and tries capture Elizabeth but Meliodas saves her and runs away. Later, while in an old tower, Meliodas tells Elizabeth to stay put while he tries to find information. Later, after Hawk ran toward them and told them what happened to Elizabeth, King decides to go back to Boar Hat to get help but then he sees Meliodas's serious face and says that they are doing it now. Meliodas and King make the plan and after Meliodas saves Elizabeth, they meet again in the Boar Hat and go to the next town.
When they get to Vaizel, King volunteers to stay behind with Diane, when she starts to complain. He then heads into town with Meliodas, Ban, and Hawk, after Elizabeth decides to stay with Diane. After hearing about a weapon no one can use being used a prize at a tournament, King says that a sacred weapon can't be in place like this. He is the shocked when Meliodas and Ban decide to enter the tournament. He then tells Meliodas and Ban that looking for the sacred weapon comes before horsing around. When he sees the prizes, he notices that one of them is Diane's sacred treasure Gideon. He is the pulled into the sign in line, which he is choked when someone picks Meliodas up. He is then put down when someone helps them out. He then recognizes the person that helped them and wonders where he has seen him before.
Later, King enters the arena and wonders how he was dragged into this. King is having some doubts about this and tells Meliodas that Diane will be angry by doing this but Meliodas tells him that Diane will be very happy if he wins, something that gives him some motivation. During the preliminaries round King is running away from his opponents and when the preliminaries round end, King passes the round by not getting hit but the people say he is cheating since he is floating but the head of the torment lets him go. Meliodas and Ban tease King for being cheap which annoys him.
King's next opponent is Cain Barzad who is the one who showed them where the sacred treasure is and King is upset that Ban put his name as "Old Fart". During the start of Griamore and Matrona's fight, Matrona reveals that she is wearing Elizabeth's clothes. King tells Meliodas that she might be Elizabeth but Meliodas tells him it's not her since her breasts are slightly smaller and her butt is a little bigger, much to King's confusion. After Matrona wins and her face is revealed to be Diane, she later punches Meliodas in the stomach for not recognizing her. King follows Matrona and asks initially about her size and then where Elizabeth is, only to be revealed that she is in Diane's bosom and both of them have shrunken.
After Diane and Elizabeth tell them what happened to them, Diane jumps happily on Meliodas, shocking King who has a nosebleed after hearing what she wants Meliodas to do to her. Ban informs King that his fight will start soon, and then asks him whether he is already dead due to the great amount of blood he lost from all the nose bleeding. While King is waiting for his fight to start, Diane cheers for him and tells him to win, to which he responds by giving her his game face. Upon engaging in battle, King tries fighting Cain but despite fighting hard, because he is really weak against Cain, he is losing. King uses his power Disaster on Cain but Cain senses it and sends him flying out of the ring, defeating him.
King is upset that he lost and watches the next fight, which is Meliodas versus Ban. Both Diane, King and Elizabeth are cheering them on and King tells Ban if he loses, he will tell Elaine. During the fight, King comments on the power of Meliodas and Ban and is very glad he doesn't have to fight them. Later during the fight between Meliodas and Diane, all the sins sense great danger coming toward Vaizel and King and the rest put up an act to scare the people away from Vaizel. The Holy Knights Jericho and Guila then appear and the Sins split up to fight them each of them alone. After King took most of the people out of Vaizel, he returns to find Meliodas and Ban defeated by Guila and Jericho, but after King defeats them with great ease, he gives the injured Meliodas and Ban to Elizabeth and Hawk to watch over them while he tries to get information out of Guila and Jericho.King then tells the Holy Knights if this is just an act for a bigger event bur Guila simply smiles and tells him that the Seven Deadly Sins will be defeated. King then senses that Meliodas and Diane's powers seem to be completely gone and asks them if they know anything about it but they attack King again. King tells them if they attack again, he will kill them and uses his Spirit Spear Chastiefol Form Four, Sunflower to finish them. The giant plant shoots out its attack but is sliced in half and the girls are saved by Love Helm who reveals himself to be Helbram, which shocks King greatly. Helbram greets King, addressing him with his real name, "Harlequin" and Guila and Jericho immediately state their readiness to support Helbram but he refuses; he instead instructs them to recover the target. When Helbram questions King's nervous expression, the Fairy King, bewildered, questions Helbram as to how he is alive, a question that Helbram dodges. King expresses his confidence in his power, and has a regenerated Chastiefol attack Helbram. Helbram, though commenting on Chastiefol's regeneration, kicks King, while easily blocking Chastiefol.
King fights off Helbram, but is easily overwhelmed by the latter who even stops his spear attack in mid-air. Right before Helbram cuts him, King launches a spear attack at Helbram that lands on his face, hence removing the helmet and revealing his face. Helbram then senses Meliodas's raging power coming toward them while King is utterly shocked to sense Meliodas's dark power and gets knocked out by the force of it, when Meliodas lands to their location. While Helbram watches the defeated Meliodas, Ban gets both King, Elizabeth, and Hawk and starts retreating from the area since Diane got her Gideon back. King later wakes up and gets his wound treated by Meliodas and Ban. The group then heads to a new location to find the next Deadly Sins or sacred treasure.
King then told Ban that he isn't acting himself and might be trying not to think about thinking, but Ban then appear behind King in quick speed and toss him toward a boulder to which he stop himself from crashing. Ban told King that he just wanted to crush the Holy Knights and take back the kingdom as soon as possible. King was then surprised to see Ban caring about other peoples business to which Ban told King he feel the same where, but King revealed that he wanted to stop the Holy Knights because he wanted to help Diane.Ban then reveals to King that he wants to get the Horn of Cernunnos which shocked King because it is a treasure of the kingdom and asked Ban if he was planning to steal it, but Ban told King that since he is going to save the kingdom, the horn would be a good reward for him. King then reveals the legend of the horn which could have the ability to communicate with the Goddess Clan, King was then shocked to find out that Ban is planning to use it and ask the Goddess to revive Elaine from the dead since it wouldn't be a trouble for a Goddess. Ban then told King he should take him more seriously which King agrees to. While sparing, King reveals to Ban that the main reason he isn't acting like himself because of Meliodas' change in form at Vaizel and that his power resembled Guila and Jericho, but more sinister.
King started to think that Meliodas could be from the Demon Clan but was stopped by an angry Ban, who yelled at King and said that Meliodas isn't the same as the monster. King was confused about the monster Ban was talking about, but Ban told King that Meliodas took him in despite being an outcast and being a bad person. Ban told King that only two people in those world accept him for who he is and those were Elaine and Meliodas. Ban then told King that Meliodas would never kill anyone, no matter how bad they were, saying he was too naive to be the same as the monster he fought. Ban and King later met with Diane and Elizabeth who later went to find Meliodas. They were surprised to see a slice up mountain caused by Meliodas.
King and the others later meet up with a group of kids who are role playing as them, and later befriended them. Everyone was later informed that a group of Holy Knights were spotted at the mountain to which the kids went there to find them. Later, the Deadly Sins were told by a dying knight that there is a Armor Giant at the mountain which defeated the knights easily. Meliodas then revealed to everyone that giant is Gowther.
King, Meliodas, and Ban headed to the forest to find Gowther, to which they find him having a stand off against the Dawn Roar. However the stand off was broken when one of the kids Pelliot attack which smash another kid named Armando. The Deadly Sins then headed to the battlefield while King was shock why would Gowther attack Armando to which Meliodas told King that they would worry about that later. King rushed in and took Pelliot away from the battlefield before he get hurt. King then use Form Third, Fossilization to petrify Hugo however, Hugo arm was cut off by Simon to save him which shock King, but then King was trapped by a Dawn Roar member. As Weinheidt was about to shoot Gowther with a powerful arrow, it was stopped by the injury boy Armando who then reveals himself to be Gowther to the Deadly Sins shock.After Gowther made the Dawn Roar leave the battlefield by offering the Armor Giant head, Gowther reveal to the Deadly Sins that the Armor has a beast in it which was once a Holy Knight. Gowther left the battle field to make sure Pelliot is save from the beast. The Deadly Sins then face off against the beast with King using his Chastiefol Form Two, Guardian to save Meliodas and Ban who were sent flying by the beast. The Guardian, however, was defeated by the beast with ease, which shocked King. King told Meliodas he will attack Dale with Fight Fire With Fire-Raining Daggers but it had no effect on Dale, who then spit out Venom Spit which effected King greatly. King was then carried by Gowther and was amazed when Meliodas kill Dale ease with a real sword. King went back to the bar, feeling better and having a party with the Deadly Sins for Gowther's return. Everyone started smelling King due to Gowther revealing who King is by smell and noticed he smells good in his normal form but bad in his human form, to his dismay. Gowther used his power Invasion on King to reveal that he could have killed Dale with ease but did not want to because of Helbram, but King shut Gowther mouth with Guardian. When Gowther revealed that Elizabeth is in love and possibly Meliodas, King quickly tried to calm Diane down before she could attack anyone but was surprised that she was pass out due to drinking.
When Meliodas asked for his team's aid in retrieving his stolen weapon, King chided his captain for being careless until the Meliodas explained the nature of the item. After Elizabeth was captured by a female Holy Knight, King witnessed Diane giving Meliodas, Ban, and Gowther a very long throw to the Kingdom of Liones, much to their astonishment. Diane and King started to travel to Liones on foot along with Hawk's Mother and plan to help out since they are the only two who have Sacred Treasures with them. Diane asked King if he had ever seen Meliodas that angry before to which King said that it was his first time seeing the him like that. Diane wondered that if she had been kidnapped instead of Elizabeth, would Meliodas get that angry for her, but King told her Meliodas will come for her since they are important friend to which Diane said that Meliodas is kind, but said that Meliodas wouldn't make a face like that.
King told Diane that he will definitely come for her even if he does it alone which made Diane happy, but wonders if he does it to cheer her up. King realized that they should hurry and summoned his pet, Oslo, which King revealed its ability and try to transport them to Liones quick. But Diane was too big for Oslo and told King to push her butt to get her which made King blush and ordered Oslo to get bigger quick. When Diane was struck by Gilthunder's Thunderbolt attack, King witnessed Oslo being affected by that technique. After his comrade managed to fully enter from Oslo's mouth, King tended to his wounded pet. As Dreyfus was under Gowther's Nightmare Teller, a past version of King was seen glaring angrily at a drunken Ban next to table where Meliodas, Hendrickson and Dreyfus converse. King somehow manages to get to Liones to save Diane from Helbram, however, Diane was already in a near death state by Helbram which made King look in disbelief. King flew down, trying to find the one who damaged Diane. However, Diane said that it wasn't Guila or Howzer since they both tried to protect her, but King punched Howzer despite his weak strength and started to blame them for not protecting her well. Howzer tried to stop him, because he saw the bleeding in King's hand, but saw that King was crying because he was unable to protect his loved ones.
Helbram called King out for being too late for Elaine and seven hundred years ago, and start attacking him from above. But, King fought back with even greater power he had in Vaizel. Helbram handled all of King attacks and mention that King had a lot more power than in Vaizel which King told Helbram to return to his true form and wanted to fulfill their promise of fighting against each other with full power from seven hundred years ago. Helbram turn back to his true form as a Fairy. King mentioned that he did not know it was Helbram back in Vaizel since he was wearing an old helmet, but an angry Helbram quickly attacked King with a strange power that resembled a Great Holy Knight's power. Helbram told King that he couldn't get rid of his old helmet as it remind him of who he was, but King yelled at him to shut up. Helbram wondered what King see in Diane, but King ask Helbram he should understand how it feels to lose someone.
Helbram started using the Sacred Tree branch to attack Diane, but King used all of his attacks to protect Diane from dying. As King was knocked around by the Sacred Tree, Helbram mention that King is unable to fully use Chastiefol to is true powers as the Sacred Tree that was forge from it, forsaken King for his failure in the past and that since Helbram is a "True Fairy", the Sacred Tree is on his side. Helbram summon his roots to ruthlessly kill Diane as King watched. As the smoke cleared up, Diane (as well as Howzer, Guila and Zeal) was protected by King with Chastiefol barrier form Form Eight, Pollen Garden as Helbram looked in shock as King used up all of his power to make the barrier. Seeing Diane safe, a wounded King smiles.
King flew up close to Helbram, the latter wondering why the Sacred Tree had not forsaken King and allowed him to draw out so much power. King explained that the Chastiefol eighth form was made to protect others and slowly heals them as the Sacred Tree had pollen to heal itself when attack. King looked at Howzer and told him he was lucky to be near Diane when the healing shield appeared, as were Guila, Zeal, Gowther, and Jericho. King told Helbram that the Sacred Tree was born to protect the Fairy Realm, and has no sentiments of evil. King explain that is the reason that he has the ability to draw out more powers than Helbram. King asked Helbram whether he still intends to kill humans, Gustaf and his comrades who were allies to Helbram through Link, were shocked of their superior's true nature and as when the Cardinal ordered his subordinates to give all their powers to him, Gustaf and the others tried to break their connection to Link, only to be taken control by Helbram's Blind Follow and gave all their powers to the mad fairy to battle the Grizzly's Sin of Sloth. King summoned Chastiefol back to him and prepared to fight Helbram to his fullest power. As the two Fairies clashed with each other with their weapons, Helbram was starting to have a mental breakdown while King remind calm and told Helbram he could rest now, as King slash Helbram, defeating him and breaking his Link orb.
Before Helbram fell, he told King they were too late as Hendrickson had the Coffin of Eternal Darkness and Elizabeth, all the keys required to release the Demon Clan, King asks how Elizabeth was the final key, but Helbram told him to see for himself as he fell. King went close to the near-dead Helbram and picked up the helmet which Helbram revealed was meant to be a gift from him to King when he got it from the humans seven hundred years ago, and said he was stupid as the helmet was dumb and ugly. King started to break down in tears, saying he agreed and left the helmet on top of Helbram's dead body. King floated towards the injured Diane and apologized to her for getting her into trouble, but Diane instead thanked him for saving her. King told Diane to leave everything to him, but Diane then said Harlequin which surprised King until Diane said that name simply sounded nostalgic to her, but didn't know why. King smiles and said it could have been a dream. Howzer asks King that if the Deadly Sins aren't after the kingdom, why were they here. King explains that Elizabeth was kidnapped and they came to rescue her, but Dreyfus appeared out of nowhere and attacked King from the back. However, the Fairy King used Chastiefol to knock Dreyfus away and held him away by floating the blade at the his neck. King told Dreyfus that according to Helbram, Elizabeth was going to be used to bring back the Demon Clan, possibly through sacrifice. Howzer was shocked to hear this news, and Guila reveals that Hendrickson was behind the plan and the New Generation were a part of it. King continued to ask Dreyfus if he was a part of the plan and should pick his answer carefully or die.
Diane attempts to get up while King tries to convince her to rest since she is still badly injured, but Diane refuses as Elizabeth needs to be saved and King's pollen healed her. As everyone gets ready, King tells Diane if Elizabeth is Diane's precious friend, then he would do anything to save her and that Elizabeth is the reason that all the Deadly Sins are reunited. The group then heads out to Hendrickson's location to save Elizabeth. While on their way, King and the other Sins sense a large amount of power exerted with very strong force in a nearby battle. Gowther explains that Meliodas is fighting against three Great Holy Knights, at which Diane begs King to go and help Meliodas. King refuses as he wants to remain near Diane since she is still injured and knows that Meliodas is fine on his own. After being joined by Meliodas, Gilthunder, and Margaret, the group heads to the castle to rescue Barta and Elizabeth. On the way, Meliodas explains to the group about Gilthunder's situation and Arthur informs them of his identity and reason for being in Liones. Suddenly, the group are teleported to a forest. King attempts to fight Vivian, but her returns to Liones, leaving King and the group to be lost in the forest. Fortunately, the group are teleported back to Liones by Arthur's cloaked friend, who is soon revealed to be Merlin of the Seven Deadly Sins.
After Merlin set Elizabeth and Baltra freed Elizabeth was worried over Diane wounds until Diane revealed that she was saved by King and was glad she was fine. Meliodas point out that they have defeated Hendrickson and freed the king, and ask Dreyfus what would he do now. As Dreyfus admitted defeated and was crying to know Griamore is alive, Meliodas happily declare that everything was fixed. However, after Merlin, Arthur and Baltra left to treat the king wound, the castle was attacked by Hendrickson and awake every New Generation demon blood. As Jericho transform into Demon and was about to kill Jericho and the slowly transforming Guila, Gowther along with Diane appeared and stop Jericho from killing. Gowther used Invasion on Jericho and Guila to keep them calm. King seeing the situation, was about to kill Jericho to save Diane as she has few strength left. However, Meliodas stop King for a moment and told him it was strange how all of the New Generation suddenly became Demons, and realize someone has active them. Hendrickson came face to face with the Deadly Sins and the Holy Knights, explaining that he did all of this and was after Elizabeth. Hendrickson offers to spare Meliodas and the others if Elizabeth come with him, as he doesn't want to kill "one of his kind", but the group refuse to hand over Elizabeth to him, and King ambush him until he was attacked by Helbram who was revive thanks to Hendrickson forbidden technique. Hendrickson explain to King how he found Helbram and that now he is just a lifeless shell of his former self which brought the Fairy King to tears, knowing that his friend is a slave to Hendrickson. Battling Helbram again, King pleads his best friend to stop.
While fighting against each other again, King refused to fight him as he already killed him twice, and doesn't feel right to kill him a third time. Ban then attacked King which infuriated him, until Ban explained it was Meliodas's order as captain of the Deadly Sins to take things seriously. Helbram drew out his last remaining will to tell King is fine with him if King killed him as he was still his best friend. King, however still refused to kill Helbram, still feeling guilty over how many time he killed him which made Helbram to yell as he explained that they are no longer friends which brought a tear to King eyes as he summon Chastiefol Form Four, Sunflower and killed Helbram by destroying his body as the latter smiled in relief. King picked up Helbram old helmet and wondered if they are still friends in the end. As Ban figured out a way to return New Generation back to normal, Ban and King teamed up to remove the strange "plant" inside of them while the others went and save Elizabeth.
King rejoined the other Deadly Sins member at Merlin Old Castle to face Hendrickson in the final battle. As King battled against Hendrickson with the aid of Meliodas and Diane, Ban was slam against the wall by Hendrickson which made Ban furious as he revealed that the wall he smashed against was a Red Demon, to everyone's shock. King was even more surprised when he found out that the Red Demon was in Fairy King's Forest during its destruction which made King question Ban's sin in killing Elaine and drinking the water from the Fountain of Youth. When Ban slammed Hendrickson into the ground, the Deadly Sins, without Diane due to her size, went inside with King using Form Seven, Luminosity to light the way. The Deadly Sins were shocked to see a Gray Demon which Hendrickson revealed that it has greater power than the Red Demon and put its blood into him, gaining him a new form and much more powerful as he easily destroy Ban upper half.
Meliodas along with the other Deadly Sins, were blown out of Merlin's Old Castle and badly injured due to Hendrickson's new found power. Diane, however, reacted and used Rising Meteor on Hendrickson, sending him to the sky. Diane told King to finish him, which the latter did by almost using Form Eight until Hendrickson used Dark Nebula to defeat them. King grew furious when Hendrickson killed Hawk while protecting Meliodas and Elizabeth. When Elizabeth unlocked her hidden power and healed everyone, Meliodas thought of a plan and asked Gowther to use his ability to spread the message, but King was in tears, trying to reveal to Meliodas that Gowther was killed as his head was chopped off, but to Diane and King's horror and shock, Gowther was still fine as he was searching for his glasses while holding his head. Once Gowther spread the message through Broadcast, King and along with the Deadly Sins attacked Meliodas and Hendrickson with all of their powers, which revealed that Meliodas was charging up for Revenge Counter, his ultimate technique, as it finally killed Hendrickson, ending his reign. Once Baltra returned from Camelot with Merlin by his side, he forgave the Holy Knights and cleared the Deadly Sins name for their crime. As the others started to grieve over Hawk death, the black matter on the pig dead body started to be remove and revealed that Hawk is alive, but shrunken. However, everyone was still joyful for their friend being alive, except for King who was still puzzled by Hawk's size.
As Liones is being rebuilt, King, while Oslo is on top of him, was wondering how Diane is feeling after seeing Meliodas and Elizabeth hugging each other after Hendrickson's defeat, and believed that Diane is feeling depressed due to her feeling toward Meliodas. However, King realized that this could be the chance for him to make Diane fall for him instead, but stopped himself when he realized that he can't make Diane fall for him because she sees him as her comrade instead of a lover. Oslo barked at King, which the latter understood, but he said that he is a Fairy and couldn't help. But, when a large column was about to fall on an old man, King quickly saved him by levitating it and told the old man to be more wary. The old man was thankful for King's help, and revealed that he was distracted because his wife left him, which greatly depressed King, thinking Diane could leave them due to Meliodas's relationship with Elizabeth. distracted by his emotions he accidentally drops the heavy wooden beam onto the helpless king. stuck because of the beam.
King begged for help to remove the large column until Diane appeared in a regular human size and lifted the column with ease as it surprise everyone. King was shocked to see Diane in regular size, but revealed that Merlin offered her magical pills called Minimum Tablets that allowed her to shrink for seven hours as her clothes is being repaired. King continued to stare at Diane, which the latter noticed and asked him if she looks strange in western clothes or being small in general. King, however, revealed that he doesn't care if Diane is big or small, she is still Diane, which made her smile. King asked Diane if she could invite Meliodas to the National Foundation Festival despite calling himself stupid in his head as he wanted to ask Diane, expert to his shock, Diane ask King out instead. The next day, King put Helbram's helmet on his hood to remember him as the rest of the Deadly Sins got new uniform as well, expert for Merlin. The Deadly Sins end up celebrating the festival while working in the Boar Hat along with everybody else. However, when Ban was about to leave the Deadly Sins, King comforted him and told him to let Elaine's death go, which Ban refuse and told King that he is going back to the Fairy King's Forest much to King shock.
However, King doesn't believe Ban as the latter tends to lie a lot, and that he saw the burned down forest ten years ago, but Ban decided to leave him and went on his journey. Having trouble believing Ban, King followed the bandit in order to find out the truth despite meaning leaving the group for a short period of time. While following Ban, they spotted Jericho who was following them as she was still mad at Ban for stripping her clothes and power from before. As the three journey together, Jericho questions the existence of Fairies and the forest which King realizes that she was born after the forest was burned down. When a fog appeared out of nowhere, Ban told them that they were there much to King and Jericho's shock, they found themselves in the newly made Fairy's King Forest to King great joy as he also spot his old Fairies friend, Cisca, Ende, and Melik. However, King was greatly saddened and shocked to find out that his friends hate him for leaving the forest for seven hundred years and now believe that Ban is their new king instead of King. Still depressed over the Fairies hating him, King continued to journey inside the forest with Ban protecting him, finding Elaine's grave which brought a tear to his eye before he ran away. King grew more depressed, questioning how could he face Elaine's grave, still seeing himself as a failure when a group of Fairies appear and start attacking King until Oslo arrived and defended King.
When Oslo asks King to return back to the kingdom, King brushes it off as he knows he is not needed in Liones and wonders what he should do since he's either a Fairy King or one of the Seven Deadly Sins which again humid his eyes, spontaneously wearing Helbram's helmet when he ended up not only hearing his old best friend's voice, but seeing him as well. King freaked out and wondered what is happening until Helbram explain that his spirit rests within the helmet and only King could see him once he wears the helmet possibly by killing Helbram three times, but unsure about the theory. Helbram joked around, saying that he can't enter the Capital of the Dead due to either unfinished business or killing humans for 500 years, but Helbram tells King that Elaine asked him to look after King and to protect Ban. While King sulked over Elaine's message, Helbram ends up mentioning Hendrickson which scared King, thinking the villain is still alive, but Helbram brushes it off as he thought he was overreacting. Later, King asks Jericho when she is planning to leave as only a few selected humans were allowed to be in the forest which Jericho replied that wherever Ban goes, she would show more value than a dead brat which Ban overhears and strips her out of anger. Ban revealed that he was not going back to the Boar Hat and was planning on going on a journey to find a way to bring Elaine back alive to which Jericho offered to come along as his disciple however, Ban refuses.
However, King tries to convince Ban to return by asking Merlin for help or to fix his relationship with Meliodas which Ban refused. Ban than teases King, saying he should return back to Boar Hat as Diane will "die of loneliness" if King isn't with her which made King mad for teasing him until Ban revealed that it was true when a few days ago, Diane admitted that she is lonely without King while King went out to get supplies. King was shock at this news as he believes Diane somehow regained her lost memories of him to which Ban smiled and told him to go home. King decided to head back to Diane since no one wanted him at the forest and asked Jericho if she want to go back to Liones which she refused as she want to be with Ban. As King was about the leave, a Albion appeared at the forest and start destroying it. King decided to fight the giant, but was proven too weak against the beast. However, this inspire the Fairies by King bravery and fight the beast while Gerheade take King to safety. King actually wore the helmet which Helbram told him how the Fairies became lazy and weaker after the war, leaving everything to the king, until King showed them what it mean to be strong and beg King to leave while the Fairy fought. However, King refused as he need to protect them and slay the beast with True Spirit Spear Chastiefol, which led King to be heavily injured.
However, King manage to be healed and head to Camelot to see if Diane is okay after hearing the news she was attacked. When King was taken to Diane, it turns out that Diane completely forgotten who King was and only remember what happened sixteen years ago. King decided to remain with Diane in his human form to not surprise her and to comfort her. However, Diane soon left the castle as she started to forgot more which led to Gowther revealing he used Lost World on her to test if her feelings for King are stronger than memories. King was furious at Gowther action, but quickly calm down when he realize he did the same to Diane and shouldn't judge, but still punch Gowther and went after Diane along with the others who they know that she is heading towards Megadozer to tell them about Matrona. However, they were soon being attacked by Monspeet Hellblaze which Hawk Mama ate to save them. When the group lost sense of Diane, Meliodas told King that Diane will be fine for now and should focus on training to defeat the Ten Commandments which King agreed. The group decided to head to Istar to regain Meliodas strength and to have the group trained.
While they, Jenna, one of the head of the Druids, took them to the cave of training where they will be paired up with other members to train. However, while there, they came across Gilthunder, Griamore, Howzer and shockingly, Hendrickson who is alive and human again. While the others were somewhat okay with Hendrickson fighting alongside with them, King was still furious at Hendrickson's past actions and refuse to pair with him during training. Once Meliodas finish his trial, he went to the cave of training and paired up with King. However, once inside, King started to fight him instead of the Amber they were supposed to choose. King started to question Meliodas motivation and that if he was on their side which Meliodas refuse to answer, saying that King wouldn't believe him anyway. After much battling, the two come to an agreement to work together while King keep an eye on him.
Meliodas, with the help of Merlin decides to pay a short visit to the Ten Commandments which shocks King and the others who protest against the idea. However, Meliodas goes his way anyway while they wait for 10 seconds in anxiousness. Once Meliodas is back, and after finding out about his doings, King angrily yells at him but is tuned downed after finding out about Meliodas' plan. Helbram asks him through the helmet about what happened in the cave, but king refrains from telling him. He then exits Istar along with Meliodas and the others.
When traveling, King is sitting outside the Boar Hat with Oslo when he noticed Oslo was reacting to someone summoning him. Helbram calls out to King through the helmet, warning him not to allow Oslo to leave. King puts the helmet on, allowing Oslo a chance to leave and King learns from Helbram that someone forced the gate between The Living World and The Capital of The Dead open. Stating that this person is putting a spell on the dead similar to how Hendricksen did to Helbram but a lot stronger and forcing the souls to return to their bodies with malicious feelings. King asks Helbram if the one who summoned Oslo is one of those who died only to receive a solemn look. Realizing that his sister was resurrected, King decides to take leave for awhile to sort the situation out. When explaining to the others, Meliodas tries to have King give further details about why he's leaving, only to have King tell him he still doesn't trust him because he doesn't know about Meliodas's past. Elizabeth tries to reason with King by explaining she doesn't know about her past either and it doesn't bother her only to have King explain that it's not like that. When leaving, Meliodas hollers to King that if he needs backup, give them a holler. As King flies away, a worried expression appears on his face as he wonders what his now resurrected sister is up too.
Along with Oslo, King finds the revived Elaine near the bar My Sweet Gluttony that belonged to the Lion's Sin of Pride, Escanor. He later rejoined with Meliodas and the others in Vaizel Great Fight Festival. He is paired with Diane, who still lost her memory.
King and Diane are spending time in the Fairy King's forest. Then suddenly there's an intruder, causing everyone to dance and mashes merry, including Gerheade, which sees her brother, Gloxinia. As it turns out Drole and Gloxinia are there to abduct Diane and King, which claim to train them to defeat the Ten Commandments. King and Diane are skeptical at first but, grudgingly accept and get plunged into the Holy War from three thousand years in the past inhabiting Gloxinia and Drole's bodies.
Abilities and Equipment
King is shown to be an incredibly formidable opponent, able to deftly maneuver his spear with ease. He is strong enough to overpower a Great Holy Knight single-handedly. Being a Fairy, King has demonstrated a number of abilities unique to his species; such as the ability to levitate or fly, the ability to change his appearance and clothes at will, as well as possessing great speed equal to Meliodas and Ban. Upon unleashing his true power, Meliodas and Ban commented that his strength grew to "an incredible level". This was later re-affirmed when he defeated Helbram, a Great Holy Knight level combatant, while protecting all the injured in the area; then almost immediately after, swiftly defeated Dreyfus, one of the Great Holy Knights of Liones, despite the injuries he sustained from his battle with Helbram. During his reign as the Fairy King, his power was said to be so great that it kept the human kingdom from invading the Fairy King's Forest. It should be noted that this included the Holy Knights of Liones.
Despite his great power, King is physically weak, however, he makes up for his lack of strength with his sacred treasure, Spirit Spear Chastiefol and his immense level of magic power. In spite of his lack of physical strength, he has shown a remarkable level of durability as shown in his second battle with Helbram. It was believed that King was able to control the Sacred Tree a long time ago and with it draw out the true power of a fairy, but the tree abandoned King for an unknown reason. This was later proven to be false as the Sacred Tree has no evil intentions at all and it was King who did not want to fully utilize the Sacred Tree's powers.
Immense Speed: King is extremely swift, as observed when he not only effortlessly evaded the attacks of both Guila and Jericho simultaneously, but also knocked them unconscious before either of them could realize it. He is also able to keep up with fellow sins Meliodas and Ban in terms of speed.
Enhanced Durability: Despite lacking physical strength, King has a remarkable level of durability as shown in the Kingdom Infiltration arc where he not only fought and defeated Helbram, but also, pinned down Dreyfus immediately after, despite the injuries he sustained against Helbram.
Immense Endurance: King has shown to have incredible levels of endurance as noted when he was able to take the damage of Helbram's attacks without even shielding himself to protect Diane and sustain the strikes of the great beast Albion. Part of the reason for this could be the sheer willpower of King to protect everybody and everything he cares for.

It also gives him complete control over nature, allowing him to manipulate various flora, letting it flourish or perish in moments.

- Chastiefol: King's sacred treasure, the Spirit Spear, Chastiefol, is a spear crafted from the sacred tree, only found in the Fairy Realm. It is much stronger than steel and possesses the mysterious qualities of the tree, which King's ability, Disaster, draws out. It has several different forms, including a pillow which can act as a shield, different forms of spears, and a large stuffed grizzly bear.
- Helbram's Helmet: Helbram's Helmet is a special helmet that Helbram bought from a human seven hundred years ago as a gift for King, but used it as a disguise for his Love Helm identity. Once Helbram died for the third time, his spirit rest within the helmet whenever King wears it.

King and Meliodas are both members of the Seven Deadly Sins. King enjoyed his time with Meliodas in the past and still cares about him to this day. When King joins up with the group, he occasionally disagrees with Meliodas' actions, but still trusts him as a good captain. After Vaizel, King struggles with the fact that Meliodas could be a demon himself. Despite finding Meliodas's perverted antics shameful, King still respects Meliodas for that shameful nature since King is too shy to be bold for Diane and wants Meliodas to teach him to be more bold. However, after finding Meliodas relates to the Ten Commandments, King starts to question Meliodas's true nature and whether or not he is on their side. It doesn't help when Meliodas refuses to tell him and instead questions his title as king of the Fairies. King decided to be on Meliodas's side since Diane and Ban trust him, but warn Meliodas that if he betrays them, King will kill him.

King is shown to comfort Diane whenever she is hurt or upset. When Diane was ruthlessly beaten and near death, King was willing to use all of his powers to protect her. In the past, King looked after the young Diane for five hundred years after she saved and took care of him until he was fully healed. When they meet up again ten years later, he still loves her and finds her just as adorable as she was a decade ago. Soon after defeating Helbram, Diane regains her memories and falls in love with King. King is dedicated to protecting and loving Diane.
King and Ban are both members of the Seven Deadly Sins. He hated Ban and wanted to kill him, in order to avenge his sister Elaine who was believed to be killed by Ban - even though she actually died because of a Demon's purgatory fire. When Elaine told him to protect Ban and join up with the group, King reluctantly accepts her request and assists the fight against Guila. Although he no longer despises Ban as much, he still feels uncomfortable around him. Later, King grows to accept Ban as Elaine told him when Ban reveals his plan to revive Elaine, but still feels uncomfortable.
King and Gowther are both members of the Seven Deadly Sins. King is shown to be annoyed at Gowther's clueless nature and Gowther's revealing of secrets. King grew furious at Gowther for erasing Diane memories, but at the same time, knew he was no better. However, their relationship was strained due to Gowther's actions.

King and Escanor are both members of the Seven Deadly Sins. Not much has been revealed between the two, but it appears that King is somewhat weary of Escanor, as he goes berserk during daytime.
Elaine is King's sister, who he left at the Fairy King's Forest for 700 years, protecting the Fountain of Youth. King loved his sister so much that he was upset at the discovery of her death, vowing to avenge her by killing Ban, who was reported to be the one who killed her.
King and Elizabeth share a fairly good friendship. King greatly respects her for being a princess of the royal family and her bravery for trying to pull his spear to help the sins. He is concerned for her well-being, as shown when he assists Meliodas in saving her from the Ceramic Tear Inn after she was captured by Griamore. When they were properly introduced, King was shocked to find out her identity and apologized for his 'rudeness' earlier before transforming into his human form, wearing royal attire to greet Elizabeth formally, believing that it was more respectful.
King and Hawk seem to share a good friendship, and sometimes King calls him Mr. Pig, Little Porker, or Little Piggy. King shown some respect for Hawk for trying to pull his spear to help Elizabeth to help the sins, but he shows it more to Elizabeth.
Several years ago, King and Helbram were best friends, despite having different views on humans. Helbram trusted King very much, but frequently teased him.
