the game's plot revolves around abobo's son, aboboy, who is kidnapped in the opening cutscene in a nod to the opening of "double dragon". the game's levels are mostly linear, featuring several references to other nintendo entertainment system properties with their enemies and layout. before the final level, abobo encounters jerome "doc" louis from the "punch-out!!" series. doc reveals that the real villain is his former pupil, little mac, who went mad with power after winning the championship. abobo defeats little mac in a boxing match, decapitates him with the power glove, and rescues aboboy. as the crowd cheers for the reunited pair, they suddenly leap out of the ring and begin to graphically murder everyone within reach. the events of the game are finally revealed as a dream abobo is having, a reference to the ending of "super mario bros. 2".
