During the era of the Galactic Civil War, there were Trandoshan twin brothers who operated as hired guns, or mercenaries. They sometimes crossed paths with Boba Fett on the planet Ryloth, where they created problems for him. Subsequently, these same twins found themselves working for a small mercenary force under the command of a Bith criminal known as Bounty #239, who was, ironically, the target of a bounty to be claimed by Boba Fett.
The initial reference to the Trandoshan twins appeared in a non-canon narrative created for the Boba Fett figurine within the Star Wars Mythos series of sculptures.
