Paxim

From Memory Alpha, the free Star Trek reference

Commander Paxim was a Talaxian from the Prema II colony, and an old friend of Neelix. When he originally made contact with USS Voyager, he played a part in the crew's attempts to uncover a traitor in their midst by taking on Tom Paris as a pilot, only for the Kazon-Nistrim to capture Paris for information. (VOY: "Investigations")

After the loss of Voyager to the Kazon-Nistrim, Paxim helped Paris regain the ship, as his ship and another provided cover fire while Paris, in a shuttlecraft, disabled Voyager's primary phaser couplings. (VOY: "Basics, Part I", "Basics, Part II")

Paxim was played by Russ Fega.

Fega's costume was sold off on the It's A Wrap! sale and auction on eBay. [1]
