Television
Doomsday appears in the eighth season of Smallville, portrayed by Dario Delacio. This version was created on Krypton via its strongest creatures' DNA to serve as Major Zod and Faora's "son" and kill Kal-El. Its genetic material became attached to the young Kal-El's spaceship and traveled to Earth, where it befriended Lex Luthor and was given up for adoption in 1989. Receiving the name "Davis Bloome" (portrayed by Sam Witwer), he went on to become a paramedic and fall in love with Chloe Sullivan before recognizing Clark Kent as Kal-El, which causes him to periodically transform into Doomsday. Throughout the season, Bloome struggles to maintain control over Doomsday before Sullivan uses black kryptonite to separate them and Kent traps Doomsday underground. Following this, Bloome and Jimmy Olsen fight over their shared love of Sullivan before mortally wounding each other. Witwer was offered the chance to return in the ninth season as Zod, but ultimately declined as he felt it would be difficult for both the characters and audience to accept.
Doomsday appears in Krypton. This version was originally Dax-Baron (portrayed by Staz Nair), a Kandorian with a unique genetic mutation who was convinced he would be the one to end a Kryptonian civil war and allowed Kryptonian scientists Wedna-El and Van-Zod to experiment on him until he became Doomsday. He was subsequently put into cryo-stasis, but is eventually freed in the present by Seg-El, who seeks his power to stop Brainiac despite Adam Strange's protests. Zod eventually captures Doomsday to weaponize him in his campaign to colonize other planets before sending him to Krypton's moon Wegthor to defeat a rebellion against him. After Wegthor is destroyed, Doomsday is presumed dead before being found in a frozen meteorite.
Doomsday appears in Superman & Lois, initially portrayed by Tyler Hoechlin and later motion-captured by Paul Lazenby. This version was originally Kal-El / Bizarro, a corrupted version of Superman from an inverted universe who was killed by Mitch Anderson before being resurrected by Bruno Mannheim, experimented on by Lex Luthor, which turns him into Doomsday. Throughout the third and fourth seasons, Doomsday serves as Luthor's enforcer until Lois Lane reminds the former of his time as Bizarro. Nonetheless, Luthor mutates Doomsday further, diminishing the latter's mental capacity, before Steel incapacitates the monster and Superman flies him into the sun. Though Bizarro's memories return, he allows Superman to kill him.
Doomsday appears in series set in the DC Animated Universe (DCAU), voiced by Michael Jai White. This version is an altered clone of Superman who was created by Project Cadmus to serve as the former's superior and indoctrinated with hatred for him.
Doomsday was considered to appear in Superman: The Animated Series, but writer Paul Dini refused to include him.
Doomsday appears in the Justice League two-part episode "A Better World". When he grew too difficult to control, Cadmus abandoned the project and launched Doomsday into space, but he damaged the rocket before leaving Earth's orbit and crash-landed. After returning to Earth, he battles the Justice Lords, who arrived from their native universe to conquer the main universe, until their version of Superman lobotomizes him.
In the Justice League Unlimited episode "The Doomsday Sanction", Doomsday regenerates his brain and is taken into Project Cadmus' custody until disgraced member Achilles Milo releases him to kill his superior Amanda Waller. However, Doomsday kills Milo instead and escapes to fight Superman before being defeated. After failing to interrogate him for information on Cadmus, Superman imprisons Doomsday in the Phantom Zone.
Doomsday makes a cameo appearance in the Legion of Super Heroes episode "Phantoms" as a prisoner of the Phantom Zone.
Doomsday appears in the Teen Titans Go! episode "Doomsday Preppers", voiced by Asher Bishop. This version is childish and wants to befriend the Teen Titans.
