Gray Hulk!

I was thinking of a power that captures his rage power (more limited than regular Hulk) and his viciousness:

PAYBACK
When rolling defense dice against an adjacent attacking figure, all excess shields count as unblockable hits on the attacking figure. If one or more unblockable hits were inflicted on the attacking figure, add an additional unblockable hit on the attacking figure for each wound marker on this card.

Or you could just reuse Rage Enhanced DNA.
