West Coast Avenger
John Walker was born in Custer’s Grove, Georgia to Caleb and Emily Walker. Instilled at an early age with patriotic feelings for his country he eventually joined the army like his brother Mike, who died in the Vietnam War. As soon as he was recruited the war ended and John’s hopes of becoming an American Hero were crushed. He then left the military service were he heard of a person known as the Power Broker. When he learned from his friend that the Power Broker could give anyone superhuman powers, he sought out the Power Broker and signed up for the treatment with his friends. After he gained superhuman strength Walker was confronted by a man named Ethan Thurm, who convinced Walker to become the Super-Patriot. As Super-Patriot, Walker toured the country speaking at demonstrations and rallies. One day while in New York City Walker criticized Captain America’s morals and ideals, saying that they were old and outdated. During his speech a group of men calling themselves the Bold Urban Commandos or “Buckies” attacked Walker. Walker easily defeated the Buckies and it is later learned that the Buckies were actually working for Walker at the time. Captain America eventually came into conflict with Walker and lost the fight.
Sometime later Walker was approached by Valerie Cooper and asked to become the new Captain America. Walker agreed instantly and asked his if former partners the Buckies could join him. The Commission on Superhuman Activities refused all but Lemar Hoskins who became the new Bucky. Together Lemar and Walker trained with Freedom Force’s Blob, Pyro, and Avalanche. After a little time the Commission hired Taskmaster to train Walker to be able to fight like Captain America. Meanwhile Steve Rogers used the identity of the Captain and tried to reclaim his title of Captain America. During his time as Captain America the terrorist group known as the Watchdogs killed his father and mother. Also during his time as Captain America two of his former friends became Left-Winger and Right-Winger, whom he killed while in a rage. Eventually Rogers and Walker encountered one another and battled until both Walker and Rogers learned that it was the Red Skull who was manipulating the two of them. After the battle Walker finally realized what the costume symbolized and returned it to Steve Rogers.
Months later, the Commission held a demonstration of their new operative, U.S.Agent. In the demonstration U.S.Agent faced off against the Iron Monger and easily defeated the armor and its pilot. He then was sent on several solo missions including one against a British team called the Super Soldiers. On one of his early solo missions he joined forces with Captain America to stop a faction of Watchdogs. During this battle Captain America was worried about what Walker might do to the Watchdogs since they killed his family. However Walker restrained himself and proved himself worthy to Captain America.
Later, he was ordered to join the Avengers West Coast by the government in order to keep tabs on them. While in the Avengers he had frequent fights with fellow Avenger Hawkeye and fought many villains such as Magneto, Doctor Demonicus, Ultron, Hydro-Man, Grim Reaper, and several others.
