He was young and inexperienced; as a result, fellow Maquis resistance fighter Kenneth Dalby was very protective of Gerron during their time on Voyager. Gerron was reticent, to the point of rudeness and, as a result, was ordered by Commander Chakotay along with three other former Maquis members, Chell, Mariah Henley and Dalby, to undergo a rigorous Starfleet Academy-style training scenario conducted by Lieutenant Tuvok and aimed at brining former Maquis personnel unfamiliar with Starfleet standards and in dire need of some discipline up to date. During one of the exercises he was almost killed by a plasma leak but was rescued by Tuvok and the rest of the team. (VOY: "Learning Curve")
Gerron was played by Kenny Morrison.
In the VOY - The Brave and the Bold novella The Third Artifact his name is given as Gerron Ral. He was serving in Chakotaty's cell aboard the Geronimo which was abandoned in 2371 after being hit by one of the Malkus Artifacts.
