History Recap / JusticeLeagueS1E8And9InjusticeForAll

** Luthor doesn't execute Batman or even the Cheetah after they are no longer useful to him.

* ArtEvolution: Like Superman, Luthor's character model from ''WesternAnimation/SupermanTheAnimatedSeries'' was re-designed for his debut on ''Justice League''. In addition to discarding his familiar STAS business suit, the new Lex is now taller, with broader shoulders, lighter skin, and altered facial features (a softened brow and pronounced cheekbones).

** Joker is the only person who realizes that leaving a cat lady alone with Batman is a bad idea, clearly recalling how Catwoman saved Batman from him. Case in point, the scene transition from Batman and Cheetah kissing is Joker directly saying that Cheetah has been with Batman for too long. He also argues against BondVillainStupidity, saying he knows firsthand how badly that can backfire.

* NeverMyFault: Luthor blames Superman for his cancer, but nobody made him carry kryptonite around, and he could have been more careful (Batman carried a ''shielded'' chunk of kryptonite [[BetrayalInsurance "just in case"]], and he lived to [[WesternAnimation/BatmanBeyond a ripe old age]]). Lex's response to being told the bad news is to shout at Superman, "This is your fault! All of it!"

** Once Joker exposes Batman's tracking device (meaning the Dark Knight almost certainly knows their location), Luthor realizes Batman's unwittingly given them a golden opportunity. Instead of fleeing their base, the Gang stands their ground and sets a trap. While it's not outright stated, it's clear Lex (likely with Joker's insight into Batman's psychology) is gambling the Dark Knight will be investigating alone and not bringing the League. He's right and they're able to easily capture Batman, giving Lex a chance to interrogate him and obtain Bruce's access keys to the Watchtower.

* ContinuityNod:
** Similarly to the Batwing back in the Pilot, Batman is still using the redesigned Batmobile that debuted during ''The New Batman Adventures''.

* CallForward: Downplayed, but Joker's character model is the redesign that debuted during''WesternAnimation/BatmanBeyondReturnOfTheJoker'' (or rather during its flashback).

* WhamEpisode: Luthor's criminal activities are finally and irrevocably exposed, ending his STAS-era status quo as a CorruptCorporateExecutive. In revenge, Luthor expands his private war against Superman to encompass the entire Justice League -- a conflict that will have repercussions all the way through the end of the series and the DCAU.

* {{GetOut}}: Invoked by Lex when Joker comes a calling at the end of Part I. Considering what happened [[Recap/SupermanTheAnimatedSeriesS2E16To18WorldsFinest the last time Joker was in Metropolis]], you can't really fault Lex here.

* CallForward: Downplayed, but Joker's character model is the redesign that debuted during ''WesternAnimation/BatmanBeyondReturnOfTheJoker''s' (or rather during the TNBA flashback).
