* AlternativeCharacterInterpretation: Superman gives up his powers when he is forced to kill Mr. Mxyzptlk. This is either his noblest act... or his most selfish.
* CompleteMonster:
** {{Brainiac}}. He brainjacks Luthor in the most horrifying way possible, murders most of Superman's remaining friends, and is completely devoid of anything resembling a conscience.
** Mxyzptlk is far beyond Luthor, Braniac or even [[Film/ManOfSteel General Zod]] in that he's an EldritchAbomination, practically an EvilGod who was going to wreak havoc onto ''the whole universe'' if Superman had not stopped him, and the only way left was to put him down permanently.
* CrowningMomentOfHeartwarming: The Elliots' son is named Jonathan - or rather, as in Jonathan Kent.
* HilariousInHindsight: Jordan Elliot looks like [[Comicbook/{{Watchmen}} the Comedian.]]
* {{Squick}}: The Luthor/Brainiac Teamup.
