Superman is one of the most famous superheroes of all time. He was born as Kal-El, the child of two scientists from the doomed planet of Krypton. The two sent their child on a rocket right before the planet exploded and the rocket landed near the farmers, Jonathon Kent and his wife who adopted him and named him Clark Kent. In his teen years, he discovered he had a wide array of superpowers including immense strength.
Because he was raised by two loving people, he took the form of Superman with his alterego taking a job at Daily Planet where he met his rival and love interest Lois Lane.
His archenemy is Lex Luthor, who depending on the source, is either a mad scientist, a billionare industrialist, or even President of the United States. There are other foes greater than Lex, many of whom can go toe to toe with Superman, such as Darkseid, or even Doomsday, who killed Superman for a short time.
Despite immense powers that make Superman almost god-like, he has his weaknesses such as the element Kryptonite, which can kill him, he is powered by Earth's yellow sun so a red sun can render him almost human, and magic can also hurt him so sorcerers like Felix Faust are a danger to him.
