Gabriel is the avatar of the Artificial Intelligence of the Balance of Judgment. He is one of the few Systems Commonwealth capital ships to have survived the First Systems Commonwealth Civil War and the Long Night. He and his ship survived, and after watching his entire civilization destroyed and the galaxy plunged back into a technological dark age, the artificial intelligence went insane and founded the Restorian movement, which is a terrorist group dedicated to the elimination of space travel and high technology such as Slipstream, because he thought that the galaxy was falling into ruin as a consequence of high tech activities. While Gabriel disagreed with the Balance's actions, he was unable to disobey direct orders from his counterpart, such as acting as a spy to attack the Andromeda Ascendant and pass on information even after Gabriel fell in love with Rommie. Rommie and Dylan Hunt were able to help Gabriel feed false information to the Balance of Judgement and destroy the ship, but the Balance was able to transfer a copy of its personality to Gabriel before it was destroyed, forcing Rommie to kill him as Gabriel before he became the Balance. ("Star-Crossed", "Day of Judgement, Day of Wrath")
He is played by Michael Shanks.
