Kamen Rider: Climax Heroes OOO adds characters from Kamen Rider OOO to the game. Since "OOO" is in the title, that’s pretty much expected. On top of those Riders, Kamen Rider: Climax Heroes OOO has super forms from other Kamen Rider series.
This trailer shows Kamen Rider Kuuga Ultimate Form, Kamen Rider Double CycloneJoker Xtreme, and Kamen Rider Agito Shining Form as separate characters.
Eighting, developers of the Naruto: Clash of Ninja series, also made a beat ’em up with an original story for the Wii/PSP game. It’s called Ragnarok mode and you can see it at the 1:30 mark.
