The Avengers are a Marvel Comics super team of heroes. Led by Captain America, the group also includes Iron Man, The Hulk, Spider-Man, Wolverine and Thor. Their boss is Nick Fury who is director of the peacekeeping organization S.H.I.E.L.D. Together, they literally save the world from alien invaders. Not the best of friends, they come together when danger faces them. It is a great shirt for Hulk fan and Comic Book fans alike.
