This article is about a set of riders in Kamen Rider mega-event as seen in the Kamen Rider Series.
For a list of Riders by series, and some that are not included in this list, see:Kamen Riders
They are the Lead, Secondary, & Extra Kamen Riders who fought for battle against the forces of evil. They are led by Takeshi Hongo (Kamen Rider Ichigo).
As there was merely one Kamen Rider in the very beginning, the number has of course increased greatly since then. This gallery shows previous "all rider" unions over the years.
All main up riders up to Decade (with Diend). Note: Kamen Rider J is absent due to a point in the movie's storyline which saw him in a giant battle with King Dark.
