The Boys (TV series) and Invincible start as Superman pastiches. That’s what they are but what’s important is that both Omni-Man and Homelander evolve to become their own characters with unique psychological profiles and placements in their world.

It’s usually an incredible oversimplification when people say that either is just evil Superman. It’s ironically so lazy. Better examples are Overman, Ultraman, Brightburn, Hyperion (Heroes Reborn) etc. Even then, some grew beyond their original homages and tropes to become interesting characters in their own right that have a vague resemblance to Superman.

But I agree. Invincible, Omni-Man and The Immortal all share vague traits to Superman. General Zod does have a son named Lor Zod. Heroic version was pre-New 52, closer to Invincible and became Nightwing, while there’s another version of General Zod’s son who’s evil like he is.
