Portrayal in adaptations
In Middle-earth: Shadow of Mordor Brûz is an Olog-hai seemingly willing to help Talion and Celebrimbor rise to power. When Brûz helps Talion with occupying the fortress in Núrn, it turns out that the fortress was ruled by Ratbag and Ranger.

Brûz put himself forward as Overlord but Talion gave that position to Ratbag, much to the discomfort of Brûz. Eventually when Talion captured another fortress, Brûz decided he wanted to be Overlord and betrays Talion. Brûz started an uprising, killing followers of Talion and Celebrimbor. Brûz captured Talion's Warchiefs, but the chiefs were rescued and Brûz was defeated by Talion. He still managed to escape, after which he kidnapped Ranger. When Talion went in and saved Ranger, Brûz was defeated again. This time Talion shamed him until he lost his mind, preventing further actions from his side.
