Jupiter Ross was an assassin in a secretive Terran Confederacy military unit, alongside Gustav Lorca, Gregg Moonstone, Kon Rennie, Romy Pyrius and Banta West. Pyrius was unsure if this was his real name.
In 2483 he and the rest of the team raided a meeting to kill the targets. However, Pyrius, a drug dealer, had hatched a side deal which compromised the mission. Ross and the others were killed; Pyrius, who ended up selling them out, was the only survivor.
