After rescuing mercenary Rianna Saren from a Black Sun smuggler, Zeeo became her companion; she then removed his [restraining bolt](/article/restraining_bolt-legends], and in exchange, he gave her access to his database containing information on Imperial computer systems. Zeeo proved to be quite useful while working alongside Rianna during her conflict with the Imperial slaver Zarien Kheev and her investigation into the Death Star project. While on Coruscant, he assisted Rianna in the theft of an Imperial shipment; on Alderaan he hacked into the main computer of the Agricultural research vessel to gather intelligence regarding its purpose; on Mustafar he overloaded the main drilling shaft; on Tatooine he aided Saren in defeating the rancor; on Despayre Zeeo downloaded the Imperial codes that allowed them to escape the Death Star and on Danuta he saved Rianna by sacrificially taking Zarien Kheev's final shot. Furthermore, he was responsible for opening numerous doors, disabling alarms, and deactivating force fields. As a capable fighter, Zeeo could stun enemies using electricity and was armed with a potent weapon – the Dual Cannon.
