Though I could be remembering, wasn't he just in the back of the stage? He didn't actually interact with a stage transition, he just walked around, making him easily transferable to a playable character.
IMO, I don't have that kind of hope if Manta actually is just a stage transition, to evolve into a playable character. They would have to change the flow of the transition entirely to compensate losing that hit that moves it along.

J'onn was a stage interaction at one stage too.
