GAD-3 was a droid designed for labor who performed tasks aboard the Odionite space station known as The Spike in the era of the second Charge Matrica.
During 1032 BBY, the Jedi Knight named Kerra Holt reprogrammed GAD-3 while she was on a mission to The Spike, and he assisted her in damaging the station. After Kerra instructed him to deactivate the containment fields, he, along with various other droids and at least one Verpine crew member, were pulled into the vacuum of space and were likely decompressed.
GAD-3's only appearance is as a small, supporting villain in Knight Errant: Aflame 3—a component of the Star Wars: Knight Errant comic series—that came out on December 8, 2010. John Jackson Miller created the character's backstory, while Ivan Rodriguez provided the artwork and Michael Atiyeh was responsible for the colors.
