Brollo, a Gamorrean mercenary, served within Jerec's contingent of the Imperial remnants around 5 ABY. Displaying his rank, he sported a blood-drinking morrt on each of his biceps. His assignment placed him on Sulon, where he was tasked with protecting the Katarn residence. Blotho, his relative, took part in combat events that drew wagers from Imperials and fellow mercenaries.
Jerec enlisted him, and while Jerec was on his quest for the Valley of the Jedi, Brollo was detailed to protect the Katarn estate alongside soldiers of the Imperial Remnant. He engaged in betting matches with Stormtroopers. While on patrol at the estate, an Imperial soldier offered him another wager, presenting a datapad to choose between Kine and his own cousin, Blotho. At that instant, the droid WeeGee forced entry through the kitchen's rear access; following a brief moment of surprise, both men reached for their weapons only for Brollo to be struck down by a blaster bolt fired by Kyle Katarn. His comrade met a similar fate shortly thereafter.
