18. Stan Lee Created The Incredible Hulk in 1962
The superhero, whose alter ego was Dr. Bruce Banner, almost didn’t last, though. The comic book was canceled after only six issues, but the character was revived in 1968 in the comic book Tales to Astonish. The comic book went on to be called The Incredible Hulk and was later shortened to just Hulk. Today, despite going through multiple changes and iterations, it is one of the longest-running comic books of all time.
