He's even voiced by Tim Matheson, who voiced Lord in Justice League Unlimited. Jarvis Kord, Ted Kord's Evil Uncle, takes Max Lord's role as Ted's killer.The Reverse Flash is Eobard Thawne, but he has Hunter Zolomon's red and black eyes.The show generally stopped doing this after Darkseid was properly introduced about halfway through Season 2.

In early episodes, Mongul and his sister Mongal often took over roles more associated with Darkseid and his lieutenants, like commanding the Female Furies and Steppenwolf.

Likewise, Vilsi Vayla is a combination of Vicki Vale (name and appearance) and Lois Lane (personality, voice actress, and relationship with the two Batmen). The Batman of Zur-En-Arrh is an existing character in his own right, but his civilian identity (largely unexplored in the comics, but heavily expanded on in the show) is heavily inspired by Clark Kent.OMAC enemy General Kafka is combined with the completely unrelated character Shrapnel, for no reason that's easy to figure out.Equinox is two Justice League of America villains: Libra (balance-obsessed, cosmic-powered villain) and the Gray Man (embittered and crazy ex-agent of the Lords of Order).And his mother isn't Talia, like comics Damian, or Kathy Kane, like Bruce Jr., but Catwoman like Helena Wayne of Earth-2, who became a vigilante in order to avenge the death of her mother, and continued on, taking her father's place after his subsequent death, in this case, both Batman and Catwoman die at once due to Joker's protege Joker Jr.

(complete with the Framing Story of Alfred writing fiction).

The TB&TB incarnation of Damian Wayne combines elements of three separate children of Bruce Wayne from different continuities - obviously he gets his name from Batman (Grant Morrison), but the story he appears in is more like the Golden Age 'Imaginary Stories' with Bruce Wayne Jr.

The TB&TB version of Cheetah is Priscilla Rich, but like her successor, possesses superhuman abilities that were given to her by Urzkartaga.

In the comics, the Golden Age Cheetah was Priscilla Rich, a wealthy American socialite who had no powers and wore a cheetah costume, while the post-Crisis Cheetah was Barbara Anne Minerva, a British archaeologist who was turned into a superhuman cheetah creature by the plant god Urzkartaga.

As of Brightest Day and the New 52, the Rusch/Raymond combo has appeared in the comics as well. Unusually this switches their positions, as normally Ronnie was the physical body of Firestorm and Martin was the voice in his head, now, Jason is the intended physical body though with a lot of added musculature, and Ronnie speaks in his head, switching the muscle and brains around.

The animated version was formed by a combination of gym teacher Ronnie Raymond and his student, a pre-teen Jason Rusch (now a science whizz-kid to provide Stein's atomic knowledge). After his death, the new Firestorm was teenager Jason Rusch, who would combine with whomever happened to be nearby but would eventually combine with his friend Mick Wong, then Stein, then Firehawk, then his girlfriend Gehenna. In the original comics, Firestorm was an amalgam of slacker student Ronnie Raymond and physicist Martin Stein, then Raymond and Mikhail Arkadin, then Raymond on his own.
