Blaster Master 2

It has been four years since Jason's Encounter with the Plutonium Boss and the radioactive mutants under the Earth. His only reminder of the incident is S.O.P.H.I.A., the vehicle he used to stop them, which he has hidden in an abandoned barn. One day, one bolt of lightning struck the house and caused the ceiling to crumble, knocking Jason unconscious. When Jason woke up, S.O.P.H.I.A. was in pieces and the parts he had collected from his first dealings with the Mutant Bosses were missing.
