U.S.Agent (Earth-111)

A government agent named John Walker was the second man to receive the super soldier formula. Walker was originally to become the New Captain America, but after Rogers was released from stasis, John wanted his own superhuman Identity. Taking the name "USAgent" Walker also joined Toxin's resistance. USAgent's weapon is a circular sharp edged shield like Captain America's, but it is made of pure Vibranium and emits sound waves when struck.
