One of DC Comics' most powerful villain species can rewrite reality itself, though imps like Mister Mxyzptlk are surprisingly non-threatening.

In James Gunn's Superman, Lex Luthor employs an incredibly fantastical concept to gain the upper hand in the DCU film.

The DC Studios head James Gunn said a miscommunication led to Henry Cavill's exit from the Superman role. Still, Gunn hopes to bring Cavill back into the DCU.

Before James Gunn settled on Lex Luthor and Ultraman as the villains of Superman, he's recently confirmed that at least one other villain was in the running.

Lex Luthor is Superman's best villain, but he isn't the first. This villain was the first to content with Superman, but nobody remembers him.
