Since Super Climax Heroes is coming out on November 29th, this gave Eighting the opportunity to give Wizard the ability to use his Flame Dragon Style in the game. And just like Rider Generation 2, Fourze will also have access to all 40 Astro Switches, which will make his mastery almost equivalent to using OOO.
Judging by the trailer, Eternal will get to equips all of the T2 Gaia Memories, which will be perfect for those that want to reenact the final battle from the Kamen Rider W A to Z movie. Taking into consideration that the last trailer did not feature any fedoras, Kamen Rider Skull made sure to fix that problem. Kamen Rider Joker will also be playable for those that fall victim to Eternal's special ability.
I think that it's safe to say that Super Climax Heroes will give players more flavors on how they want to kick their opponents to smithereens. And with all of these new characters, the only missing contenders are the rest of the Showa Riders. Then again, there might be some more unlockable Riders, since it would be mean to reveal the game's real secrets before the release date.
