Peturabo

Peturabo, primarch of the IV legion of space marines and perpetually irate atist is one of the god emperor of mankind's test tube babies. He wants to be loved and appreciated, but doesn't try to connect to people, he want's glory and honor, but just does the meneal jobs and makes himself be unnoticed, he want's to prove himself worthy of trust, but plays warhammer 40k.

oh, he also had the gate to the space in between dimensions looking at him at all times.

that didn't do much to improve his mood.

No one respected him and he took it out on his men, belittling them and sacrificing them, also he ordered them decimated.

After his younger brother's temper tantrum aganced their dad failed, he went into the aforementioned gate to beond and made the occasional pact with extradimentional demon gods and building evil demon robot tanks

in his spare time he enjoys bitching and moaning, and fucking with his younger brother Dorn.
