Gilgaros strongly resembles his Boss Yo-kai counterpart Ogralus in that he is an imposing figure with clawed limbs, a fang-filled smile, two horns jutting from his head, and a red ponytail. He carries a huge spiked club. Unlike Ogralus, however, Gilgaros is a yellow-gold color and wears a purple scarf with some black splotches that matches his loincloth.
As a Yo-kai imprisoned behind the eight seals of the other Crank-a-kai exclusive Yokai, it can be said that Gilgaros is the most terrifying Yo-kai of all. However, upon his release, he is friendly enough to give his medal to the player, something no other Oni of his calibur would do until the second game, indicating he is at least thankful to have been released.
