"This bold vision of the future requires a vast military dedicated to upholding the enactment of universal laws which are necessary to ensure galactic harmony.
In truth, these actions are taken merely to protect us from those who would invade, enslave, or foment political dissent, and to punish accordingly any who engage in such acts.
Look on our new military not as trespassers or interlopers, but as gatekeepers, here to shore up the Emperor's vision of a pacified and prosperous galaxy."
Yes. Justice Lords, Injustice Gods, Ultraman, Overman, S/B Absolute Power, Superman: The Dark Side, Red Son, Irredeemable/The Plutonion, Marvel/King Hyperion, Invincible/Omniman, The Boys/Homefront (plus arguably one or two others).
Those are 11 off the top of my head. I am entirely sure that is not a complete list.
'Let's make an evil Superman' is one of the most common ideas in comics.
They did make a character called 'Superman' in a short story before him, but he didn't bear much resemblance to the one in the comic. He was a telepathic villain- with a bald head notably, so he might've lead to Lex Luthor.
