Lon Suder was a Betazoid male who served aboard the USS Voyager in the early 2370s. Suder joined the Maquis in 2370 and joined a cell led by Chakotay. Over the next year, Suder proved an effective member of Chakotay's team. When Tharia ch'Ren, a fellow crewmate aboard Chakotay's ship, the Geronimo, came into possession of a Malkus Artifact, it was Suder who detected a difference in his mind, an effect of the Artifact.
