Also known as: ジラース
A Dinosaur-like Kaiju from Ultraman (1st Series). Like Gomess before it, it resembles Godzilla, in terms of design as well as having the same suit actor, Nakajima Haruo.
While Jirass has reappeared more recently, due to how little he differs from Godzilla (with the suit being a combination of MosuGoji's body with DaisensoGoji's head, with an added frill), Gomess is often utilized instead if the intent is to make Godzilla references to avoid running afoul of Toho (Movie Company)'s copyright.
