Captain America's shield (Ultimate Avengers)

Captain America uses his Shield as a primary defensive and offensive piece of equipment for battle. His shield is made out of Vibranium and Adamantium.

Ultimate Avengers
In the animated movie Ultimate Avengers, based partly on The Ultimates but with several changes, Captain America uses a shield containing vibranium. In the Ultimate universe, Captain America used his triangular shield throughout World War II, only gaining the disc-shaped vibranium-bearing shield after he awoke in the present day. The composition of the triangular shield remains unrevealed. It did prove to be bulletproof against the bullets of World War II German soldiers, but was dented by a superhuman alien's punch.
