Kaiju
CharacterKaiju turns Ryuichi Gojiyama into a towering dinosaur pulled straight out of a monster film, a Vigilantes-original Quirk witnessed only while its user is dosed with Trigger. What the power actually does under ordinary conditions has never been established.
Overview
Written as Kaijū, this Transformation Quirk works at melee range and belongs to Ryuichi Gojiyama. It debuts in Chapter 14 of Vigilantes and reaches the screen in that series' Episode 8.
Mechanics
Every appearance of the Quirk comes while Ryuichi is running on Trigger, which leaves its unenhanced behavior a blank. What the audience does get to see is a shift into an enormous dinosaur-like creature modeled on Godzilla. Kuin Hachisuka likens the result to Gigantification.
Notable Users
Ryuichi Gojiyama is the only holder. The Quirk is a deliberate nod to Godzilla, placing it alongside Toho as another reference of the same sort. The anime altered his monster form to sit closer to Godzilla's own design, and his vocals were built from modified Zilla roars taken from the 1998 Tristar film, layered with TIE Fighter sound effects out of Star Wars.
