Nevo once served as an Imperial assassin; he and his squad infamously murdered a multitude of uninvolved individuals while attempting to eliminate their intended target.
Although Nevo and his team were initially condemned to die, Darth Vader intervened and altered their punishment. Vader, aiming to obtain Abal Karda along with his enigmatic box, enlisted the skills of Boba Fett. Subsequently, Nevo and his associates were contracted to assassinate Fett and deliver the box back to Vader. Nevo's accomplices included Fraal, Gann, and Lumus.
The group received a swift vessel and a tracking mechanism, employing them to monitor Fett's search for Karda. Without Nevo's crew realizing, Fett knew that Slave I was being tailed. After uncovering the group's mission, Fett ambushed and eliminated Gaan at Starstation 12. Despite this loss, Nevo pressed on, eventually encountering Fett on Maryx Minor, where the renowned bounty hunter killed him and his entire team.
