Superman/Enemies
From Pop-Cult Guides
[edit] Enemies
Superman also has a rogues gallery of enemies, including his most well-known nemesis, Lex Luthor, who has been envisioned over the years in various forms as either a rogue scientific genius with a personal vendetta against Superman, or a powerful but corrupt CEO of a conglomerate called LexCorp.
The alien android (in most incarnations) known as Brainiac is considered by some as the second most effective enemy of Superman. The enemy that accomplished the most, by actually killing Superman, is the raging monster Doomsday. Darkseid, one of the most powerful beings in the DC Universe, is also a formidable nemesis in most post-crisis comics.
Other enemies of note include the demon Satanus, the fifth-dimensional imp Mr. Mxyzptlk, the Ultra-Humanite, the imperfect Superman clone or duplicate Bizarro, criminal cyborg Metallo, Kryptonian criminal General Zod (and other Kryptonians imprisoned in the Phantom Zone for their crimes), the Parasite, the Prankster, the Cyborg Superman, Terra-Man, the Toyman, Composite Superman, Gog, and the Metropolis gang known as Intergang (which includes mad scientists such as Dabney Donovan and Thaddeus Killgrave).
