I only know of the water head Habsburg, what about the other ones?
Well, the penultimate Hapsburg monarch is pretty much responsible for World War I, so...
Granted, he was part of the Austrian branch as opposed to the Spanish branch that gave us Charles II and are synonymous with royal inbreeding.
Walt Disney.
Look deep into your heart, you know it to be true...
Let's be real here, if Walt Disney was a Late Millennial or a Zoomer, he'd be a slightly higher-functioning /pol/ kiddie and probably also be an unironic eugenicist like MovieBob.
Granted, he pretty much was pro-eugenics IRL but it was a lot less of a taboo in the pre-WWII era.
Well, you do have the Womb Wizard at least? She hasn't claimed to be literally channeling the ghost of Michael Jackson since her parents chopped down the internet for trying to seduce preteens on Deviantart though.
Damn, beat me to it.
On the topic of artcows, Andy Warhol because fuck that guy.
Andy Warhol would be either one of the site's biggest lolcows or one of the site's greatest shitposters, sort of like GG Allin in that regard.
As for some other dead celebrity lolcows, I'd figure they'd play out in certain ways.
Kurt Cobain would be a whiny SJW soyboy bugman
Marlene Dietrich would be an arch-thot with an OnlyFans page
Andy Kaufman was pretty much the prototype for Sam Hyde and Deagle Nation
Huey Long would be an internet political grifter like Sargon or Vaush
John Holmes would probably be a horrorcow or a careercow
There's a fuckton of groups that would deserve a thread in Community Watch if KF existed back then
The Puritans, Jacobins, Posadists, Libertines, Japanese Red Army, and the Ghost Dance are some of the ones that immediately come to mind.
