For the Delta Quadrant species, please see Devore.

Devor was a member of a group of mercenaries that boarded the USS Enterprise-D during preparations for a baryon sweep in 2369 at Arkaria Base with the intent of stealing trilithium resin.

Their plan was foiled when they were discovered by Captain Jean-Luc Picard, who was still aboard the ship. Devor was the first of the mercenaries to be encountered by Picard, who soon realized their plan and subdued him with a Vulcan nerve pinch. When he came to, Picard questioned him about what was going on, and when Devor refused to answer, Picard used a hypospray on him. Devor was presumably later killed by the baryon sweep.
