Perturabo
Primarch of the Iron Warriors.
Greatly known for his mastery of siege warfare. He is feared for his status as a Daemon Prince, and his Rage, which is mainly due to an itch to the back of his head that he cant scratch due to the cable wiring (refer to the picture on the right). In other words,he's one big, mean and badass motherfucker who knows how to make the strongest thing go down.
Whats also known about him is his rivalry with Rogal Dorn. What we know about these two is that their quarrels is equivalent to the typical sibling rivalry.While Dorn's Daddy's Golden boy,Perturabo serves as the incredibly jealous brother who just wants to tear his brother limb from limb.This is probably what started the rivalry with the Iron Warriors and Imperial Fists.
He joined Horus and the other traitor legions during the Horus Heresy. However, Horus lost and they all fled to the Eye of terror like little bitches.
The Iron Warriors go on to be one of the most used Chaos Legions in Black Library Writing, while Perturabo goes on to...entirely drop out of sight since then.
