Originally a Soviet scientist, Vostok was formed in an unexplained incident involving extra-terrestrial technology. Radically transformed by the encounter, Vostok became a new lifeform of synthetic matter and tech who no longer answered to his previous identity and instead took up the initial name of Sputnik. He became a founding member of the Supreme Soviets, then changed his name from Sputnik (the first unmanned Soviet space mission) to Vostok (first manned Soviet mission) to reflect his growing humanity.
