I was bored so I was thinking about if Arc-Sys developed a "serious" Kamen Rider fighter in the vein of FighterZ, probably sticking with the Heisei Riders at first---
One thing I was thinking is it seems the form change gimmicks most Riders use would be a bit too much to balance it seems for a competitive fighter, and be hard on the animators, yet simply using each Rider's Base form might get a bit redundant since there's a lot of overlap. So, it got me thinking---what if each Rider was basically set to one form, and then we got some more diversity? It might be a bit odd to say, headline Drive in Type Technic, but I think it'd be neat overall---and like the intro animation could show them transforming from their default. With that in mind, here's what I thought of.
Kuuga - Mighty Form. The "Ryu" of the game, a no-thrills fighter who'd be easy for beginners.
Agito - Trinity Form. Basically dual-wields the Storm Halberd and Flame Saber, a fairly simple character but with great reach.
Ryuki - Well, there's not much to work with---so just the base form, and he'd incorporate Dragoredder into his attacks, like summoning fireballs to rain from the sky and such? Not really sure how you'd work in his cards.
Faiz - In his default form as well, and I imagine him as a "street brawler" with a lot of swagger-style moves. I want one Rider who prominently uses their bike, and he seems like a good choice, working in Auto-Vajin as well.
Blade - Jack Form. Basically he'd be capable of limited flight alongside his natural sword skills, and he'd work in the Thunder Deer card allowing him to utilize various electrical attacks since that's a rarer element among the Riders.
Hibiki - Also the base Form. Basically a combo-fiend with his drumsticks. Maybe work in the Disc Animals somehow as well?
Kabuto - Masked Form. Slow moving but purposeful character with powerful attacks with super armor, would have a meter allowing him to access Rider Form for certain moves, and probably some cool counters. A "smart" fighter, basically.
Den-O - Liner Form. Would basically be an assist-based character like Captain Ginyu, summoning the Imagin to aid him. Really weak on his own, thus relying on the Imagin to protect him.
Kiva - Garuru Form. A very "feral" fighter with lots of combos, both on the ground and in the air, I added Garuru Form for some cool sword techniques in addition to his fist-based attacks.
Decade - In his default form, I feel like him transforming into other Riders would be a bit much---maybe for a cinematic Ultimate Move, but I'd probably use the original cards he showed off like the invisibility and multiplier. A "trickster" character perhaps overall?
Double - Cyclone Joker, naturally. Wind-based, and could split in two for certain attacks for some nice mix-up options.Basically a more advanced version of Kuuga as the fist fighter.
OOO - Tatoba. I was thinking of a gimmick where certain combo strings result in a medal being added to a gauge---if you line up three of the same type of medals, you get a stat boost. Like RaToraTa increases speed, SaGoZou gives super armor, etc. But otherwise he's kind of like Kiva, a quick "savage" fighter but more grounded.
Fourze - Magnet States. A "tank" character with limited mobility, but lots of firepower backing him up.
Wizard - Ground Style. I think this would be cool to make him a defensive character able to summon barriers and such.
Gaim - Jimba Lemon. Just because an archer is always cool to see in a fighting game.
Drive - Type Technic. A very "mechanical" character with a lot of traps and such to utilize like that attack that increases gravity, auto-aiming, etc.
Ghost - Billy the Kid. The "gunner" with a lot of quick-fire attacks, and of course would have some ghost-based abilities like phasing in and out, teleporting, etc.
Ex-Aid - Maximum Mighty X. Basically the large grappler character.
Build - NinComi, because we need a ninja and that's pretty cool.
