A New Transformation

Originally aired on October 1, 2001 (between episodes 35 and 36), the Special features all three Riders plus the first appearances of G3 Mild & Agito Shining Form. Shouichi encounters his old friend and teacher and fights an Unknown at night and reaches Burning Form, but goes out of control. Then, the teacher helps him control it. All three Riders fight against the Beetle Lord. The story is ended with a mysterious girl stalking G4 project and to be continued in the movie.

There is a difference concerning the series' plot and the special's plot. In the special, Tōru Hōjō finds out the truth about Shouichi's identity by secretly hearing a conversation between him and his teacher, as he stands behind a window and listens to them. In the series, however, Hōjō ambushes Agito as he flees from the battle scene and sees as he reverts back to Shouichi, ultimately arresting him.

Project G4

Released in theatres on 22 September 2001, Project G4 was a double bill with the Hyakujuu Sentai Gaoranger movie, "Fire Mountain Howls!". Shouichi encounters a teenage girl called Sayaka, who ran away from a military facility because of an attack by the Ant Lords. Sayaka has a supernatural ability to foresee the future. Risa Fukami, of the military group GA, wants to use that power to enhance the newly-made G4 System, which was based upon designs stolen from Ozawa. Now, Agito and Gills must fight to stop the Ant Lords' attack, as G3 and G4 settle their score. The events of the movie happen between episodes 41 and 42.

Kamen Rider Agito

Story

A man named Shouichi Tsugami has lost his memories. He doesn't know who he is, where he came from, or how he came upon his peculiar circumstances. Tsugami, seemingly for no reason, transforms into a powerful superhuman, Agito, whenever in the presence of the beings referred by the police as the "Unknown", a race of powerful monsters that have been causing murders around Tokyo, targeting certain people as their prey. In response, the police department unleash their newest weapon: the G3 powersuit, originally developed to fight against the "Unidentified Lifeforms", the enemies of No.4 (Kamen Rider Kuuga). G3 and Agito don't know whether they should join up and defeat the Unknowns, their common enemy, or to combat each other, keeping the mysteries that entwine them separate. Ultimately, even more mysteries unfold, with the appearance of Kamen Rider Gills, who is on a search to uncover why his father committed suicide. These mysteries and others collide, as the true nature of Agito would ultimately determine the fate of humanity.
