Superman is the most famous and well-known comic book character in the history of pop culture. This fact is true, even if Superman is not as popular with modern fans. In fact, Batman is more popular than Superman with modern fans. While fans love Superman, he is hard to relate to because he is so omnipotent. He has invulnerable skin, can fly, has super speed and reflexes, heat vision, X-ray vision, and numerous other powers. It’s obvious to see from the way he is written that Superman will never really die.
Depending on who writes the character, Superman is basically immortal. Yes, Superman infamously died in 1992 at the hands of Doomsday. Still, the Man of Steel came back to life. Superman had limited powers when he made his debut in Action Comics #1 in 1938. He didn’t even fly back then; he only leapt tall heights.
