i don't really know much about marvel comics i just think about what characters would have cool mechanics to put into the game and spiral had a pretty interesting form of zoning in a game that they are trying by design to make more zoning-centric
although it is true that marvel themselves have to approve characters and they generally base it on media stuff so unless spiral's gonna be in a movie or tv show soon it'd be super-unlikely that she'd get in
