So Lex's deal is he believes Superman, an alien, makes the human race seem inferior.
Now we know when he says 'human race' he just means himself, but that's what he claims.
But this makes me think about how he regards (or should regard) Wonder Woman.
As we know, officially, according to DC Diana is 'second only to Superman' in power. So therefore she is Earth's most powerful native-born defender.
Does that mean anything to Luthor? Should it?
Yeah, he could easily see her divine heritage as automatic disqualification, but what if he did (or outwardly claim to) hold Diana in some special regard or respect because she's, in his view, 'one of us' as opposed to an alien?
I don't know where this would go.
Even if Luthor was genuine, no way Diana would trust him--and she'd probably be put-off by his 'native vs. alien' perspective. And being Luthor, he would certainly try to weaponize it against Superman in some way, even if he did like/respect her.
I'm just thinking it could be interesting if there was something to Wonder Woman and Lex Luthor's relationship. Tension, suspense, drama...it could even just be funny if Lex hates all the heroes except Diana (sort of).
As it stands, they just seem to vaguely dislike each other via association with Superman.
"Ah, my old arch-nemesis Superman......and Wonder Woman, to whom I've fairly indifferent."
Food for thought.
