Since discovering his powers, Whirlwind has used them for crime. He has clashed frequently with the Avengers, and has become obsessed with revenge against the super hero community. Aside from high-speed melee attacks, Whirlwind is able to manipulate air currents to attack his foes from afar.
Another scumbag with powers. Whirlwind got a bit more creative with his costume, but at heart he's just another bully. He'll respond reliably to fear and greed, in that order.
