The Xonti Brothers were a duo who managed a gladiatorial business during the time of the Imperial Era. The first brother along with the second brother at one point trained five aliens, including the Wookiee Krrsantan, who was exiled and unwillingly forced to participate in gladiatorial combat in fighting pits. Following the Battle of Yavin at some point, the Xonti Brothers were present at an auction overseen by Doctor Chelli Lona Aphra. Upon seeing them, Black Krrsantan made an attempt to assault them, but Aphra incapacitated him with a stun. As Aphra finalized her bid, Eternal Rur was freed without her knowledge by 0-0-0 in order to coerce her into setting him free from his programmed constraints. The Xonti Brothers tried to get away, but Black Krrsantan apprehended and abducted them. Paying his life debt, Black Krrsantan subjected the Xonti Brothers to the same treatment they had inflicted upon him, forcing them into rigorous training against their will.
In Doctor Aphra (2016) 12, Chelli Lona Aphra calls one of the brothers Corlac Xonti, though it remains uncertain which of the two bears that name.
