Kiva could've gained more monster forms! I'm pissed the mummy is used as a "Legendorga"!

These two create some of the best concept arts for no non-existent Rider forms or their own version of existing Rider forms. Especially the first one, I prefer most of his Legend Rider Damashiis than the ones that currently exist

Garren King form and Leangle Jack and King Form. An actual final form for Mach instead of the Chaser Mach. FangMetal and FangTrigger. Black Core Medal combo.

Hmm...I am really want Kamen Rider Chaser use busou forms (Cobra, Bat, and Spider) because in toyline, Kamen Rider Chaser can use Mashin Chaser's weapons.

Hmm... Zangetsu Jimber Melon Arms.

And also the missing Tire Mixtures for Type Tridoron, or hell the missing tires in general. Like I know they only did it for the ones they had the models for, but it's weird that Grand Prix wasn't one of the ones that made it in. Especially because of the way Drive has that arm port for a formula tire in Type Tridoron.

Plus I really wanted to see Tough Guy, that just sounds like it would have been fun to see. Or even American Dream, that would have been a hoot.

OOO with the Poseidon Medals.

I'm pretty sure that'd just be Poseidon wearing the OOO Driver.

You never know~

I would have liked to see a Mirage Form Agito(the one from SIC Hero Saga) in live action.
I also would have liked to see Accel Joker or Skull Joker.

Seems the Wright Brothers would've been an easy choice for Ghost luminaries. It's not like they didn't use a pair--of brothers, no less. The ability they give a rider is quite obvious.
