^^^ I thought he said somewhere's that he wasn't Gamma ?.
... If so..., Maybe Lava Radiation ? ... Sure looks like it with those Eye's of his.., and his Blood ?.

Thinking about the Red Hulk....maybe this has already been explained, maybe not....but I thought gamma-radiation always mainfested itself as GREEN (except for the Gray Hulk stuff)...where'd the Red come from?

Cosmic Energy combined with Gamma Radiation, according to Fall of the Hulks Alpha that came out this week. He's a product of the Intelligencia's (Leader, MODAK et al) experiments.

I guess we can assume that it's the same Cosmic Energy that gave the Fantastic Four their powers.
