What do you mean by this?

The concept of a basically invincible lone lunatic antihero, mostly, though his power is more something weird about duplicating to create ablative versions of himself or something? I'm still unclear on what he's doing or what his power is even though it's halfway explained pretty early on. He's kind of silly, but not in Deadpool's particular style.

This sounds really interesting, too, considering how reactionary the genre is.

I was absolutely blown away by how it's both incredibly absurd but also positive and good. I've just started watching the anime adaptation and that's also very slick so far, and is actually colorful and vibrant to the point of absurdity as a reflection of the main character shaking off his depression and noticing how vibrant and colorful the world really is even as that world is ending around him.

This just sounds like Queen's Blade lol

Oh Booty Royale is absolutely trash, it's just also fascinating because as much of a cumbrained weirdo as its author is he's also clearly at least somewhat leftist and is constantly interjecting like actual stories about real things into his silly borderline-hentai manga that's like 50% slice of life stories about how shitty and exploitative the idol industry and its skeevier adjacent industries are and 50% weird martial arts nerd stuff, and then trying to also handle queer issues as respectfully as a fundamentally exploitative story can and in a way that's also an explicit condemnation of real-world bigotry. It's too weird and gross to like actually recommend to anyone ever, but it's also an absolutely fascinating spectacle because of how it vacillates between horny weirdness and stuff like stopping the story to educate its readers about the Rohingya genocide.
