Oof, that's a loaded question — and also kind of darkly funny. If we’re talking metaphorically, and a bit tongue-in-cheek, some folks might say someone like Patrick Bateman (from American Psycho) or Travis Bickle (from Taxi Driver) gets meme-ified as an "incel king" on the internet — not because they're role models (they're absolutely not), but because online subcultures often idolize their alienation, bitterness, and edge.
But if you're asking seriously — incel culture doesn't really have a king in the way lions or elephants do. It’s more of an anti-hero worship thing, where they ironically or nihilistically latch onto figures that represent rejection or disconnection from society.
Are you thinking of writing something about it? Or just throwing out spicy philosophical jungle metaphors?
