If it's crap ... We'll tell you
She's underrated? lmao
I don't remember ever playing this character, so I don't know if she's good or not, but I'll be damned if that's not one of the stupidest character designs I've ever seen.
Oh Rainbow was a blast to play with in Alpha 3 if you took the time to learn all her quirks and her several variants of the same move. As for the design, I think it's really cute and distinctive.
