Captain America (Earth-20080502)

Captain Steven Grant "Steve" Rogers is a World War II veteran and is known as the world's first superhero. Born in Brooklyn, New York City, the young Rogers suffered from numerous health problems, and upon America's entry into the Second World War, was rejected from military service despite several attempts to enlist. Determined to serve, he ultimately volunteered for the top-secret Super Soldier program, and the frail Rogers was enhanced to the peak of human perfection. He soon joined the war effort as a mascot, given the moniker of Captain America, and later joined the war in a combat role after he single-handedly liberated captured Allied POWs.

From 1943 to 1945, Rogers attacked multiple HYDRA quarters with his team, the Howling Commandos, in an attempt to capture HYDRA's leader, the Red Skull, and recover the Tesseract. His famous World War II exploits made him a living legend, and during this time he formed a relationship with SSR agent Peggy Carter. Despite losing his best friend and teammate, Bucky Barnes, during a mission, Rogers carried on to help the Allies win the war, but crashed into the Arctic during his final mission. His close friend Howard Stark spent time looking for his body, to no avail, although Stark managed to locate the Tesseract in the Arctic waters. Rogers spent nearly 70 years encased in ice and trapped in suspended animation before he was found by S.H.I.E.L.D. in the early 21st century.

Awake once more, Rogers found himself alone in a modern world that he hardly recognized, and devoted his time training in a gym. After an Asgardian named Loki stole the Tesseract from S.H.I.E.L.D. and declared war on humanity, director Nick Fury, enlisted Rogers' help in retrieving HYDRA's weapon and foiling Loki's plans. Teaming up with a group of individuals, along with Howard Stark's son Tony, who was a superhero operating under the name Iron Man, Rogers joined the team dubbed as the Avengers and played a pivotal role in the Battle of New York, preventing the Chitauri Invasion of Earth, apprehending Loki, and reacquiring the Tesseract.
