Gary Blackburn was a sergeant of the Eclipse Special Forces as a Titan-SS and DNA template for Project C.L.O.N.E.
Gary, like Kyle, never got to know his first clone Bassy as Anakin Nakamura, Head Director of the Nakamura Cloning Commission, never intended to have the male clones get close to their original hosts.
He had a family member named Thomas Blackburn who was a High General of the Eclipse Army.
