Hinozall is based on Level-5 CEO Akihiro Hino, which the two of them shares the same similarities in appearance. He has disheveled red hair, dyed purple at the loose ends and wears a crown on his head with a symbol resembling the kanji for "king" (Japanese: 王,"king"). His skin color is pink, with an ominous green tint that starts from top of his head until his nose. He wears a black jacket over a gray shirt. He is seen at his desk with a computer, coffee mug, a Nintendo 3DS, a cellphone and a stamped document. He has six arms in total and wears a wristwatch on the right side of one of his arms. Beneath his desk, there are four skulls seen as well a spirit in the middle. Also, around his desk are six blue wispy flames.
Hinozall is talkative and proud of his work, but he is a bit of a workaholic. He likes to create his own spaces and has a lot of potential control over the world in game. His character sometimes breaks the "fourth wall" with his powers. He also possesses a Yo-kai Watch, which he uses to summon various Yo-kai. In the Japanese version of the game, Gerappo Dance Train plays when he is fought. In the English version, the opening version of Yo-kai Watch 2 by Jeff "Swampy" Marsh plays instead.
He can teleport short distances, call for beams of lasers, sometimes referred as "The Level 5 Beams" to shoot from the sky and to call in his employees to protect him. Later in the games he can also create a very strong shield to protect himself, as well as heal himself with a "3 Hour Nap".
Hinozall also says several different phrases while battling. The phrases are "Yeah, I'll have the usual.", "Yes, one beam please.", "Get it right already!","That's It!","Good!" and "little to the right.". If the player hits him, he will sometimes react by saying "Oof" or "Ahh!".
