4. Captain America
Captain America, the alter ego of Steve Rogers (in some accounts Steven Rogers), is a fictional character, a superhero in the Marvel Comics Universe. Created by Joe Simon and Jack Kirby, he first appeared in Timely Comics' Captain America Comics #1 (March 1941).
Rogers in the regular Marvel Universe has no superhuman powers, although as a result of the Super-Soldier serum, he is transformed from a frail young man into a "perfect" specimen of human development and conditioning. Captain America is as intelligent, strong, fast, agile, and durable as it is possible for a human being to be without being considered superhuman. The formula enhances all of his metabolic functions and prevents the build-up of fatigue poisons in his muscles, giving him endurance far in excess of an ordinary human being. This accounts for many of his extraordinary feats, including running a mile in a little more than a minute. Furthermore, his enhancements are the reason why he was able to survive being frozen in suspended animation for decades. Rogers is also unable to become intoxicated by alcohol and is immune to many diseases.
Mentally, Rogers' battle experience and training make him an expert tactician and an excellent field commander, with his teammates frequently deferring to his orders in battle. Rogers' reflexes and senses are also extraordinarily keen. He is a master of multiple martial arts, including boxing, jiu jitsu, and judo, combined with his virtually superhuman gymnastic ability into his own unique fighting style with advanced pressure-point fighting. Years of practice with his indestructible shield make it practically an extension of his own body, and he is able to aim and throw it with almost unerring accuracy and even ricochet the shield to hit multiple targets. He is extremely skilled in hand-to-hand combat, sometimes taking on and defeating foes whose strength, size, or superpowers greatly exceed his. In the comics, he is regarded by other skilled fighters as one of the best hand-to-hand combatant in the Marvel Universe.
Rogers has vast U.S. military knowledge and is often shown to be familiar with ongoing, highly-classified Defense Department operations. Despite his high profile as one of the world's most popular and recognizable superheroes, Rogers also has a broad understanding of the espionage community, largely through his ongoing relationship with S.H.I.E.L.D.. He occasionally makes forays into mundane career fields, including commercial arts, comic book artistry, education (high school history) and law enforcement.
Captain America is revered by a number of other superheroes in the Marvel Universe, filling the "leadership" role which Superman takes on in DC Comics. He is considered a living legend, and many Marvel heroes, particularly Spider-Man, idolize him.
