I wonder if the silver version will be called Kamen Rider Mars Silver Arms, or maybe be named after a different planet.

Ah, now I see why. After a quick web search, it's shown that he's currently starring in a drama called "Kabukicho High School." So that's why it popped up. The name Kamen Rider Mars is shown in the third paragraph.

And it's because Kataoka is a Kabuki actor that the confusion arose :lol

Mars, ready? OK! :D

with this & the still unrevealed Silver Rider, that makes 13 right? Even with Ryuki??

Hmm...Let's count!

1. Gaim
2. Baron
3. Ryugen
4. Zangetsu/(8.) Zangetsu-Shin (if counted separately)
5. Gridon
6. Kurokage/(15.) Kurokage-Shin (if counted separately)
7. Bravo
8. (9.) Sigurd
9 (10.) Duke
10 (11.) Marika
11. (12.) Knuckle)
12. (13.) Mars
13 (14.) "Gin Rider"

15 if we separate the "Shin Riders", 13 is we don't :).

I would count Kurokage Shin since it's technically a different belt and character. He and Hase/ Kurokage will both be in the summer movie. But dude, how could you forget Kamen Rider 15 himself? :lol

And Bujin Gaim

...*Goes to corner of shame*

You sit there and think about what you've done :lol

You try memorizing every single rider after memorizing every single OOO Random combo! :lol
