In the Marvel Universe, it takes a lot to be able to play with the big boys. Thor, the Norse god of thunder, fits in quite nicely. And now, with the Classic Thor Boys' Avengers Muscle Costume, your son can fit in perfectly with any Avengers group costume. This costume is out of this world, with a blue and silver jumpsuit with built in muscles on the torso and arms, and a detachable red cape. Thor's Hammer is sold separately, and while it may not have any special powers, it looks just like the real thing. The Avengers get together to save the world against the foes who are just too big to stop by themselves, and Thor's abilities make him one of the strongest members.
