List of Superman enemies
Here is a list of supervillains appearing in DC Comics who are or have been enemies of the superhero Superman.

Unlike most heroes, Superman's adversaries exist in every known capacity; humans, metahumans, androids, sorcerers, empowered animals, other aliens (such as Kryptonians), mythical/supernatural creatures, corrupt doppelgängers of himself (imposters, clones, or parallel universe counterparts), interdimensional beings (Mr. Mxyzpltk, Vyndktvx), and even deities.
