Happy is a small blue Exceed with a white underbelly. He has a rectangular head, with pink ears, big black eyes with small, thin eyebrows, and light blue cheek marks near to his tiny whiskers (two on each side of his face). Happy has a triangular nose that leads to semi-round upper lips on the sides. Happy's body is rectangular too, and being an Exceed, it has a structure that allows him to walk erect unlike normal cats. Despite having no thumbs, Happy is able to hold things. He has a long, white-tipped tail; and the other parts of his tail are blue. Additionally, Happy is able to use his tail to hold onto objects. Happy is usually seen carrying around a green backpack, where he keeps food and items that can be used in battle. This backpack also covers his green Guild Mark that is on his back. Happy usually does not wear clothes.
Happy in the crossover shows a shocked face when he first met Hawk and is a terrible joker as he managed to make Natsu believe that their Guild Master Makarov in a Santa Claus costume was "Sunder Claws" while the story was merely a joke.

Leaf Gathering (4-koma)
Happy and Natsu enjoy gathering all the fallen leaves in the season of autumn and pile them together. Erza Scarlet appears and asks them whether it was fun, only for the two to claim that it was not.
At Magnolia Town during Christmas, Happy encounters Meliodas, Elizabeth and Hawk whom both were shocked of each others' capable of speech. Happy was grabbed and cuddled by Elizabeth due to his extreme cuteness, leaving Hawk upset.
Sometime later after completing a job requested by Hawk, Happy and Natsu were walking their way back to their guildhall. Then they saw a small red-colored person with a large sack climbing into the chimney. As Natsu wonders who it was, Happy made a very ridiculous story of "Sunder Claws". Though it turned out to be a joke, Natsu took it seriously and angrily assaulted "Sunder Claws" and Happy decided that he should pretend not to see that. In the aftermath right after Natsu destroyed the guildhall, Happy was now sweating in fear as an angry Makarov demands who told a now severely beat-up Natsu such a very absurd story.
Happy has a signature Magic: Aera. He carries a small green backpack carrying snacks.
