Ûshak

Ûshak was an Uruk of Mordor.

He is non-canonical as he does not appear in the works of J.R.R. Tolkien, and appears only in the game Middle-earth: Shadow of War.

Biography
Ûshak lived in Mordor and ran a fighting pit called "The Circus", staging countless matches between numerous creatures and races of people captured by his slavers. The Easterling Zhója usurped leadership of the mercenary group the Vanishing Sons and sold the group's former head Serka to Ûshak.

Serka's brother Baranor, rescued him from the fighting pit, killing Ûshak and his slavers in the process.
