Cornholio the Cultist
Were you looking for the character also known as Cultist-chan ?
"I AM KHORNEHOLIO! I NEED BLOOD FOR MY BLOOD GOD!"
"ARE YOU THREATENING ME? MY SKULLPILE WILL NOT WAIT!!"
Originated during the introduction sequence for when you assault Carron's stronghold in Dawn of War: Soulstorm.
Like many memes from this series, it originated due to Scott Fucking McNeil's
inability to do remotely competent dialogue unwillingness to play a terrible script straight outside of Guardsmen during the course of the game, and bringing the number of Memes stemming from Dawn of War: Soulstorm to at least Six.
During the intro sequence for the assault on Carron's stronghold, there is a discussion regarding the oncoming enemy by Carron, a Space Marine, and some Cultists. Every single unit in this intro - The Cultists, The Chaos Marines, and of course, Carron himself - is voiced by Scott McNeil, in what can only be called a glorious one-man show. Due to the Cultist unit originally having a different voice-actor (specifically, Mark Oliver, who also voices Isador), McNeil attempts to copy the dialogue style Oliver used for the Cultist - and fails utterly. He comes across as high-pitched, whiny, and sounds, in balls-out seriousness, like Cornholio, Beavis' sugar-fueled alternate persona from Beavis and Butt-Head.
Now compare it to:
Still, at least he has the balls to not run away screaming like a little bitch when the player's army overruns the Alpha Legion's stronghold. See here:
