Guardian

Guardian (James "Mac" MacDonald Hudson, Jr.), also known as Weapon Alpha and Vindicator, is a fictional character, a Canadian superhero in the Marvel Comics Universe who was the leader of Alpha Flight. He was created by John Byrne, and first appeared in Uncanny X-Men #109 which was co-plotted by Byrne and his long-time collaborator Chris Claremont. He was designed to be the Canadian equivalent of Captain America, hence his costume markings are modeled after the Canadian flag.
