The Hegemonic Brute is an agent of Derse who appears in every session of Sburb. In the trolls' Sburb session, he is exiled and becomes a member of the Midnight Crew.
The Hegemonic Brute is first seen trying to detain John's Dad. Though he has incredible strength, he is still easily overpowered by the escaping prisoner.
By orders of the Sovereign Slayer, he tracks down the White King on Skaia. After witnessing the abdication of the king to the Parcel Mistress, he attacks her and knocks the King's Scepter from her grasp. At some point during the struggle, PM decapitates the Brute with her regisword, presumably in self-defense.
After the Queen had been usurped he was tasked with assassinating Dirk before the war could begin. He was however unaware that The Prince was already awake and was promptly beheaded. His head was then rather gruesomely impaled through the Dersite flag, as a way to show Derse how much their shit was wrecked.
