The movie presents us with a very different ''TRINITY'' than the one we are used to:
- This SUPERMAN is the son of Zod, raised on earth by a migrant couple. He is direct, violent and potentially very unstable.
- BATMAN is almost a straight-up vampire. He is, in fact, Kirk Langstrom in this version, who after trying to cure his cancer with (inter-alia) BAT-VENOM, has retreated up into a mountainside home. Although he ''feeds'' on criminals, he has decided to help the innocent.
- WONDER WOMAN is (maybe?) Orion's wife in this version, with a large connection to Darkseid and Apokolips. They didn't delve too much into her backstory.
- LEX LUTHOR is sort of the ''Stephen Hawking'' of this universe. He has many physical issues and winds up in a wheelchair. A ''Demi-god'' who only descends upon the humans when he feels like it.
This is clearly a very different, very dark world, but Timm did claim that he wanted it to be as realistic as possible (outside of the JL Tower). As the movie opens, scientists (Victor Fries, William Magnus, Silas Stone, etc.) are being killed and the blame is placed on our dark heroes.
