Angorn(Demon Prince)

Originally the Primarch of the World Eaters Space Marine Legion, Angron was created Emperor of Mankind at the dawn of the Imperium, but was swept away from Terra and cast to the distant world of Nuceria. He was turned into a gladiator slave, dedicated to killing for the amusement of the masses.

During the Horus Heresy, Angron turned to Chaos. Under its diabolical influence, he became a powerful red beast wielding a massive runeblade.

After the Heresy, Angron and his army headed into the Eye of Terror, where he exists in the rank and guise of a Daemon Prince.

Capabilities
Physical Strength - After becoming a Daemon Prince, Angron's strength has grown to godlike levels, allowing him to destroy tanks, crush fortresses with his bare hands, and cut down thousands of enemies in mere minutes.
Wound Regeneration - Angron can regenerate even the most grievous wounds.
Invulnerability to conventional weapons - As a Daemon Prince, Angron is virtually invulnerable to conventional weapons.
Battlefield Presence - Angron's presence turns warriors into berserkers, as the aura of Khorne's favor increases the bloodlust of his followers.

Weapon
The Daemon Sword "Black Blade" was given to Angron as a gift after embracing daemonic powers, and was forged by the Dark Mechanicum immediately after Angron's ascension.
The Bronze Tooth Chainaxe is Angron's favored chainaxe, which Kharn picked up and began to carry as a mark of respect for his Primarch.

Role in the plot
In the mid-38th Millennium, Angron and 50,000 Khorne berserkers terrorized the Imperium for centuries, an incident known as the Dominion of Fire.
In 40444, Angron and his army attacked the Imperial Hive of Armageddon—he brought a massive force of four World Eaters and a daemonic host to destroy the local defenders and the Space Wolves assisting them. He was repelled only by hundreds of elite and trained Grey Knight Terminators.

He is loyal to Khorne.
