"I will devour everything!"
―Gaoh's phrase[src]

Gaoh (牙王 Gaō, lit. "Fang King") was Kamen Rider Gaoh (仮面ライダーガオウ Kamen Raidā Gaō, lit. "Fang King"), a fictional character appearing in Kamen Rider Den-O. He is the main villain in Kamen Rider Den-O's first movie, Kamen Rider Den-O: I'm Born!.


He is a thief-king who targets Time Trains and a renegade Kamen Rider who wishes to take over all of space-time by obtaining the legendary GaohLiner to destroy all time as he was fed up with it. He and his Imagin followers took camp at May 2000 to await his plan to come to fruition, by sending the Molech Imagin to 2007 to set the pieces up.

  • He first appeared in episode 25 of the series but he only transformed into Kamen Rider Gaoh in the movie. Gaoh is the first movie Rider to appear in three TV series episodes.
  • Kamen Rider Gaoh was originally supposed to be reused with Kamen Rider Diend Complete Form but his suit was destroyed for scraps to be used for Kamen Rider Yuuki. Despite this, Yuuki never made it as one of Diend Complete Form's cards.[Citation needed]
