>>96984658This has somewhat been forgotten, but JL/JLU was mired in rights issues.
They wanted to use Blue Beetle, Firestorm, Swamp Thing, Plastic Man, etc, but couldn't. Later on, they couldn't use any Bat characters because of The Batman or any Aquaman characters because of that attempt of a live action Aquaman show, hence the Legion not having Riddler or Scarecrow and someone called Devil Ray, who's clearly Black Manta and Aquaman not showing up at all in the final season. Rumor has it they wanted to do an Outsiders episode starring Nightwing and Black Lightning, but DC nixed it.
Even getting Wonder Woman in the show was a challenge because she wasn't the main character.
>>96985319This version of Flash didn't really resemble anyone, he was kinda inspired by the JL Europe version of Wally, but thats just the way he tried to hit on everyone, rather than his full on personality. Personally I think he acted more like Impulse than any other speedster, which I assume is intentional because Impulse WAS the speedster on the team when JL was originally pitched to Kids WB.
