|Chronological and political information|
One year after the Battle of Yavin, Tsumo was captured by Boba Fett, who imprisoned him aboard the Slave I. On their way to Coruscant, the bounty hunter discovered a lost ship floating in space, the Mingula. For the exploration of the freighter, he chose to take Tsumo with him, instead of his cell neighbor, Chung. Unlike the Ubuugan, who was wanted alive, Tsumo's life could be spent.
Aboard the derelict craft, Tsumo and Fett discovered the supposed casket of Emperor Palpatine's third cousin, Volpau, in the cargo hold and noticed the drill holes of Ubuugan fleshborers on its surface.
In the cockpit of the freighter, the two found the bodies of the Zylurian crew. They were covered with strange boils, so Tsumo assumed they died of some disease. When Boba Fett knelt down to examine one of the corpses, Tsumo grabbed a blaster from another dead Zylurian, trying to shoot Fett in the back. The bounty hunter reacted far quicker and shot Tsumo in the shoulder. The criminal stumbled backwards and dropped over a body. This caused the Ubuugan fleshborers to creep out of the Zylurian body, immediately attacking Tsumo. Unable to shake the parasites off, the flesh-borers quickly bit their way through Tsumo's skin, painfully killing him.
