[quote=@Vandy][@Morden Man] Could I not have Luthor invite Supes to the Justice League? I just don't see him doing that. Oh I started on my sheet by the way.[/quote]

Why not? Plenty of adaptations have Lex attempting to harness Superman's powers to his own end before coming to hate him. I don't think it's out of character at all.

Either way, sheets aren't gospel. They're made in a vacuum before any of the rest of the game is given flesh. Nobody is going to break a sweat if you, with the consent of whoever plays Superman, go against a minor detail in your sheet.
