Fourze trailer and OOO White Combo Pic!

 

TV-Asahi's official page for the 13th Heisei Kamen Rider series had finally been updated with the full trailer of Kamen Rider Fourze. It was the same trailer leaked from the press conference.

Gentaro is transferred into a new school and is put in Yuuki and Kengo's class. The first thing he says is to become friends with everyone. While the leader of the American Football club is suddenly attacked by the Orion Zodiart. Kengo, who is too weak to fight, decides to make a gamble and gives Gentaro the Fourze Driver along with some Astro Switches.
And for the OOO White Combo, as the rumor we heard before that OOO will henshin to this combo in the last episode using the King’s core medal that Kougami gave.
I’ve found this picture but, I don’t know whether it is Ganbaride exclusive or in the show:

As you can see, the medals he uses are:
Head: Usagi (Rabbit)
Arm: Panda
Leg: ???/not clear
Anybody knows the leg?
