But in the anime, Omosadake is also seen in episode 56 of the anime first seen helping the Hah-Hah brothers with line practice for the match against the Poseidons and is then seen throughout the episode. Recently, he has assisted Kurita on the defensive line in the game against the Ojo White Knights, using a tactic similar to the Taiyō Sphinx to hold back the defensive line against players like Ootawara.

During the semi-final against Ojo (chapter 219 of the manga), his name is revealed to be a pun; Kumabukuro, the football journalist and commentator with the massive afro, said he thought Omosadake was just dead-weight on the team - 'Omosa' means weight, and 'dake' means only.

In the anime he stands no taller than Daikichi Komusubi,
