As we already know, Kamen Rider Fourze will debut in the upcomingKamen Rider OOO WONDERFUL film. And just recently, a few unconfirmed reports gets us into the hype on what we could expect this Summer.
Please do take rumors with a grain of salt!
Eiji is having trouble fighting Gara and Kisaragi is standing there watching. Kisaragi transforms into Kamen Rider Fourze and instantly goes with a rocket punch. But Kisaragi isn't able to control Fourze properly, he flies all over the place before actually landing a punch.
He starts showing off some of his switches and powers up his arm. Kisaragi goes to Eiji, picks him up and throws him to Gara, landing on and crushing her. Suddenly, a girl calls Kisaragi and he says “Ah crap. I totally forgot the club activities.” Kisaragi leaves and it's not explained what he was doing there.
Gara is lying there and is practically dead. She takes a couple of Core Medals and becomes a giant monster. Ankh manages to borrow a few Core Medals from the other Greeeds. Eiji goes Kamen Rider OOO GataKiriBa Combo, clones himself and he starts combo changing into the other forms.
