Superman is one of the most iconic superheroes of all time, with the various iterations of this hero showing off boundless power and a zeal to serve as a noble bastion of goodness. No matter how massive the threat may be, Superman never shies away from saving innocents while stopping his enemies in their tracks. It's easy to say that Superman isn't an interesting character because of his godlike powers, but many DC villains have given him a run for his money. The fact that Apocalypse has caused Superman's death shows that even a superhero as strong as him has his weaknesses.
