Originally a Soviet scientist, Vostok was formed after experimenting with an alien vessel found by the USSR. Radically transformed by the encounter, Vostok became a new life-form of synthetic matter and technology who no longer answered to his previous identity. Vostok became a founding member of the Supreme Soviets, the officially sanctioned super-team of the USSR who replaced the Soviet Super-Soldiers.
