Hulk

Hulk (also known as The Incredible Hulk) is a prominent character in the Marvel universe, just like Iron Man and Spider-Man. And, like his Avengers predecessors, he makes an appearance on Halloween, when people dressed in inflated Hulk costumes knock on doors and ask for sweets.

The Hulk muscle suit, which costs $1,200 on eBay, isn't as attractive as the other costumes on the list, but it's still a nice buy for Hulk enthusiasts. The costume is constructed of cloth and foam fiber and is completely handmade. The purchase does not contain Hulk's trademark violet shorts, which must be purchased separately for an additional $50.
