Hulk Jimmy

Hulk Jimmy was Jimmy's Hulk-like form with freakishly-impossible strength and the ability to heal himself. It only appears in "The N-Men." Unfortunately it didn't appeared in The League of Villains, if Carl hadn't grabbed the love potion instead of Jimmy's N-Men packet. It has orange skin, green hair and eyes, and wears blue pants.

Trivia

 * This form of Jimmy is a mixture of the Hulk and the Thing from the Fantastic 4.
