Ultra-Man

Clark Kent’s Earth-2 counterpart is Clark Luthor, a corrupted version of himself who was raised by Lionel Luthor. The supervillain Ultra-Man is usually the leader of the evil Crime Syndicate.
Metallo
Played by: Brian Austin Green
Episodes: 3
John Corben was once a charming journalist but his life changed after a car accident caused him to need a kryptonite heart. He hated the Blur but his feelings for Lois kept him from being totally evil.
Deathstroke
Played by: Michael Hogan
Episodes: 2
General Slade Wilson was a vigilante-hating military man corrupted by Darkseid. Despite being wholly different from the comics’ Deathstroke, he was still a fearsome opponent for the Justice League – even killing Hawkman.
Bizarro
Played by: Tom Welling
Episodes: 5
Bizarro is a Kryptonian genetic experiment banished to the Phantom Zone. It bonded with Clark’s DNA and became a dark copy of him. It soaked up his emotions, however, giving the creature some humanity. Another very loose adaptation.
Darkseid
Played by: Michael Daingerfield/Steve Byers/John Glover
Episodes: 6
Darkseid is an ancient evil that hailed from the planet Apokolips. Unlike the comic book version, he appears to be non-corporeal and feeds off the darkness of others. He can, however, be defeated by a being of pure light – Superman.
