Red Skull is a fictional supervillain character appearing in American comic books published by Marvel Comics. He is the archenemy of Captain America and one of the most notorious villains in the Marvel Universe. Red Skull was created by writer Joe Simon and artist Jack Kirby and first appeared in Captain America Comics #1 in March 1941.

Red Skull's real name is Johann Schmidt, and he was born in Germany during the early 20th century. He was a thin, sickly child who suffered abuse at the hands of his father, and later became a Nazi soldier during World War II. He quickly rose through the ranks of the Nazi party and became Adolf Hitler's right-hand man. He was given the nickname "Red Skull" due to his distinctive facial features, which were caused by a flawed version of the Super Soldier Serum.

Red Skull's main objective is to create a world ruled by his own fascist ideology, where he is the supreme leader. He has a genius-level intellect, and is a master of strategy, manipulation, and deception. He is also a skilled hand-to-hand combatant and marksman.

Red Skull has been involved in many major storylines in the Marvel Universe, including the Secret Wars, the Infinity Gauntlet, and the Civil War. He has also been a member of various villainous organizations, such as Hydra and the Masters of Evil.

Throughout his history, Red Skull has been portrayed as one of the most ruthless and sadistic villains in the Marvel Universe, with a deep-seated hatred for anyone who opposes his ideology. His obsession with power and control has led him to commit countless atrocities, and his rivalry with Captain America has become legendary in the world of comics.
