I think these count as WTF characters that I'd pay for
She can hit people with leeks. Ulala from Space Channel 5 could also fill the rhythm game pop star position in the roster.
His story mode will need to be completed twice for the ending. Obviously he would need a costume in his underwear, like Shulk.
I hear everyone wants a keyblade wielder. Sora would be nice, but he's too obvious. Pepperouchau would be good to see. An alternate toy hero could be Dynamite Headdy, though he would play completely differently.
Vela could be a ZSS echo if needed, Vela's canon height is 6"1' which is pretty close to Samus. But she'd be better as her own character, using the huge arsenal of weapons from Jet Force Gemini. Maria Traydor from Star Ocean Til the End of Time could also fill the role of blue haired space woman with gun.
