The Kamen Rider 40th Anniversary movie, Let's Go KAMEN RIDERS, still haven't premiered, and just recently, we got some information and rumors regarding the 2011-2012 Kamen Rider series. But as of now, it still don't have any rumored name.
The rumors came from the 2ch poster Yobuko, who have been giving us solid Kamen Rider OOO rumors in the past few weeks. Please do take rumors with a grain of salt.
* This Kamen Rider seems to be loosely based on "heroes or great men" around the world, like Hattori Hanzo, Billy The Kid, King Arthur, Bruce Lee and Tarzan. The design is somewhat similar to Topgunder (a villain from Chouriki Metalder).
* These names are tentative, but the base form is "Kung-Fu". His other forms are described as "Gunman", "Knight", "Shinobi" and "Wild".
* Each form has 3 different states. The states are different from each other and the appearance and weapons change. For example: Pistol -> Dual Wield -> Rifle or Nunchuk -> Tonfa -> Lance.
* He has partners that are monsters, Dragon is a dragon. Arthur is a rock, Kid is a fox and Hanzo is a lizard. Tarzan is still a silhouette.
* The transformation item is called "Monster Egg". They are transparent eggs where you can see the monster inside. These monsters can be created synthetically. And according to rumors, there will probably be over 100 eggs!
* The enemies are called "Mazoku", basically demonic beings, inhabitants of hell etc.
* A Mazoku will show up in Kamen Rider OOO's summer movie. OOO will be using TakaJaTar (Taka, Kujaku, Cheetah) then the Mazoku shows up. When they are already fighting, the new Kamen Rider enters.
