A prominent scientist and founding member of the Avengers, Doctor Robert Bruce Banner, M.D, PhD. Banner was well respected for his expertise in biochemistry, nuclear physics, and gamma radiation.

Thaddeus Ross commissioned him to recreate the Super Soldier Serum that created Captain America, though he chose not to tell him what he was doing. When high quantities of gamma radiation were used the mild-mannered scientist discovered that when he was irritated, agitated, or thrilled, he transformed into the massive, rage-fueled, nearly mindless beast known as Hulk.

Hulk's creation may have surprised even Hulk himself, but the Avengers 2 Age of Ultron Hulk Extreme Head Knocker was purposefully crafted in such detail to ensure that it embodies its massive alter-ego! You don't need gamma radiation to have your own Hulk.

We're used to seeing Hulk smash, but if you get this head knocker you get to watch him bobble his head every day. Whether you want to put it on
