Paxim is the commander of a Talaxian colony's small fleet who agrees to join Tom Paris in attacking the Kazon-held Voyager in Basics, Part II.
Paxim appears in Basics, Part II, the opening of Voyager's third season. With the crew marooned on Hanon IV and the ship in Culluh's hands, Paris, who escaped in a damaged shuttle, makes for the Talaxian settlement at Prema II to beg for help.
Paxim is cautious about taking on the Kazon-Nistrim, and has to be persuaded that the plan is more than a suicide run. Paris has an edge: the Doctor and Lon Suder are still free aboard Voyager and can sabotage its backup systems at the right moment.
The Talaxian ships then draw Voyager's fire while Paris strikes at the weakened phaser array, the overload cripples the ship and the Kazon abandon it. Paxim's convoy sees Voyager back to Hanon IV to collect the crew.
