An eccentric psychopath, a cyborg who takes Angel's place as Rosewater's assistant and the Union's liaison in season two. Gabriel's real agenda is somewhat nebulous, though it would appear that he is straddling the fence between the Union and Rosewater, depending on who will give him the opportunity to kill the most people. He seems to have a particularly gruesome hobby of dismantling androids while they still function, as he claims to despise androids.

He becomes the pilot of Big Duo after it is reconstructed by Alex Rosewater. But as he fights Big O, Big Duo recognizes that Alan is not its proper pilot and crushes him inside its cockpit.
