James Gunn has revealed the backstory of Superman's weirdest character – and it's made me wish we saw more of him in the movie. "When people ask me my favorite character from Superman it just might be Mr. Handsome. Lex created Mr. Handsome in a Petri dish when he was 12 – he was trying to make a human," Gunn wrote on Bluesky.

James Gunn changed an aspect of Superman’s lore, which may have created a plot hole that the upcoming Supergirl movie needs to answer.
