Brian J Mason is a high-level executive in the GENOM corporation who killed Dr. Stingray and stole his Boomer technology. As with Sylia, certain mysteries are created around Mason which are never resolved in the series. It is generally accepted that Mason somehow transferred his personality into a boomer body some time prior to his death, resurfacing under the identity of Largo. Most likely, he succeeded in transferring his memories into the ultimate Boomer, thus creating a God-like being.
