Hugo's facial appearance is unknown and is an average built man with tall stature rivaling Slader's.
Hugo wears a full-body Holy Knight armor with a strange helm.
Like the other Dawn Roar, Hugo is willing to kill anybody for their mission no matter what gets in their way. He is willing to have his arm cut off as he told Simon to sever his petrified arm and has a high tolerance of pain.
Despite the Holy Knights' coup, Hugo appears to retains his loyalty to King Baltra Liones along with his teammates as shown taking orders from the king from stopping Slader from hurting himself and taking Dreyfus to jail.
Not much is known about Hugo's history but at some point of time, he became a member of Dawn Roar at the time in its formation after the disbandment of the Seven Deadly Sins ten years ago.
Before the Holy Knights' coup, Hugo and Slader served as an escort to King Baltra on a journey to Camelot in meeting with King Uther Pendragon. He was seen with Slader waiting for their king who was having a conversation with a young man named Arthur Pendragon.
Hugo and the Dawn Roar, were ordered by Helbram to travel to Ordan where a local knight spotted the Armor Giant in the forest. Once Slader and the Dawn Roar traveled to the location, they bought along a unit of knights to which they were beaten or killed by the Armor Giant who turned out to be Gowther, the Goat's Sin of Lust of the Seven Deadly Sins. Simon asks Hugo if he knows Gowther to which Hugo answers that he has seen him on wanted posters and that he was one of the Seven Deadly Sins. Slader then orders the group to make a stand off against Gowther, until he makes a move and then they should attack. Slader and the rest were waiting for half an hour until a young boy named Pelliot comes to them, which annoys them a bit and attacks Gowther, thinking he was a dangerous criminal.
Gowther was about to smash Pelliot until another boy named Armando comes in and saves his life but gets smashed instead. Slader and the rest knew that it was the time to attack to which they jump on Gowther. As the battle begins, King petrifies Hugo. Simon then saves Hugo by cutting his arm off to stop the petrification. When Armando reveals himself to be Gowther, Hugo and the Dawn Roar leave Ordan when Gowther offers the giant's head to them. After leaving the area, Dawn Roar begin discussing among themselves as Hugo expresses his wish that his team can get to fight the legendary Seven Deadly Sins.
Weinheidt and the other Dawn Roar members witness Slader's valiant attempts to save the royal family, but unable to do so due to the Perfect Cube spell placed by Vivian. Baltra orders the Dawn Roar to stop Slader from harming himself at which they immediately do but Slader refuses to leave Baltra, despite the Dawn Roar pulling him away. When the Sins and Dreyfus' group suddenly appeared in the royal bedchamber through Merlin's teleportation, Hugo and his teammates were taken by surprise and readies their weapons just in case. As Slader implies Gowther to laugh at his pathetic state he was in now, Hugo and his comrades sweat-dropped of the Goat's Sin of Pride's emotionless laugh. As King Baltra orders Dawn Roar to apply medical treatment for Slader's wounds right away, Hugo and Simon complied. Later after Dreyfus confessed his crimes and willingly surrendered, Hugo confiscated the former Great Holy Knight's weapons and asked the king of what to do with Dreyfus, almost addressing the latter's former rank. Hugo allowed Howzer's request to accompany Dawn Roar in escorting Dreyfus to his cell. Then suddenly, the castle was destroyed by Hendrickson, much to Hugo and everyone's surprise but managed to save themselves. Hugo, however was attacked and killed by Dreyfus, actually Fraudrin who then went off to fight Hendrickson along with the other Dawn Roar except for Slader and Simon.
Hugo's corpse was placed in the morgue alongside Jillian's and Weinheidt's where Slader and Simon mourn for their deaths during the National Foundation Festival.
As a Holy Knight, Hugo is believed to be very powerful and carries around a pair of circle saw-like axes that can cut through steel and is skilled enough in using them that he only needs one arm.
Hugo works well with his fellow Dawn Roar teammates as they work together as a team against the Armor Giant.
Manga and Anime Differences Edit
In the Kingdom Infiltration arc, Hugo and the majority of Dawn Roar were with Slader in the king's bedchamber and stopped their captain from hurting himself in Baltra's orders and was seen overseeing the arrest of Dreyfus who admitted his crime of murdering Zaratras and framing the Seven Deadly Sins but was later killed by the former Great Holy Knight; but in the anime, Hugo was with Dawn Roar on another mission and participates in cleaning up the New Generation mutants in the city and later appears at the side of their king in the National Foundation Festival.
