Firestorm vs. Iceman

[Captain Morgan]

Yeah, again, Firestorm is one of the few non-cosmic types that I think can outright kill Bobby.

Also, does Firestorm have blood while transformed? I don't recall the presence or absence of blood being specifically addressed, but I think that he's actually some kind of energy being.

Yes, he’s actually made of pure energy when transformed. No blood what so ever.
