Benos was a space pirate and slave trader on the planet Domo.

Benos appeared to work for Verlis. It was he and his gang who captured Kerr Avon shortly after his arrival on Domo (this was part of Avon's plan). He also took Avon's teleport bracelet (this was not).

When Avon and Nebrox came up for auction, Nebrox was able to steal the bracelet back, allowing them to escape with Dayna Mellanby's assistance. Benos fought Dayna but was shot and killed by Avon. (D: Assassin)
