Captain America

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, the young Rogers suffered from numerous health problems, and upon America's entry into World War II, was rejected from military service despite several attempts to enlist. Determined to serve, he ultimately volunteered for a top-secret Super-Soldier program, and the frail Steve Rogers was transformed into the powerful and heroic '''Captain America. '''

He later joined the fight working with several groups but ultimately joining The Invader alongside fellow heroes including his best friend Bucky Barnes who later on died in combat only fueling his rage and determination to stop HYDRA.

Near the end of his career as the Star Spangled Man, he fought his most dangerous threat yet.. The Red Skull! After defeating the man, he realized HYDRA had won. Their plans were in motion, so he sacrificed his life by crashing the large jet into the artic. He was thought to be dead for 67 years until awakening in the 21st century, Rogers learned that he had spent decades trapped in the glacial ice.

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 to prove he was fit to be king to his father Odin. Once Nick Fury found about this he assembled a team (including Rogers) to stop the oncoming threat. They defeated Loki and his Chitauri army, the team dubbed as the Avengers by the citizens of New York.
