Ryuichi Gojiyama ( () () (やま) (りゅう) (いち) Gojiyama Ryūichi?) is an Instant Villain from My Hero Academia: Vigilantes.




Kaiju (怪獣 Kaijū?): This Quirk allows Ryuichi to turn into a giant lizard. The true effects of this quirk are unknown because it is only seen whilst Ryuichi is on Trigger.


  • Ryuichi's name contains the kanji for "Safeguard, protect" ( go?), "Buddhist temple" ( ji?), "mountain" ( yama?), "dragon" ( ryū?), and "one" ( ichi?).
  • Ryuichi's appearance and Quirk may be a reference to Godzilla.
    • Additionally, parts of Ryuichi's surname are homophonous to parts of the Japanese pronunciation of Godzilla (ゴジラ Gojira?).
