Tadd Marteens was a human male from Stewjon who joined the Rebel Alliance after its victory against the Galactic Empire at Yavin in 0 BBY. A decent pilot with no combat experience, he flew an RZ-1 A-wing interceptor into battle. Not long after joining the Alliance, Marteens traveled to the planet Tibrin as part of a diplomatic mission with fellow Rebels Luke Skywalker, Leia Organa and Jaahn Liddle. During the mission, Marteens attempted to throw a grenade at a group of stormtroopers; however, one stormtrooper shot his hand and the grenade fell, throwing Skywalker to the ground, who was subsequently subdued by the stormtroopers.
