Bomberman is the first robot created by Dr. Mitsumori, a robot of incredible power, but is programmed "only for the pursuit of goodness and justice." Unfortunately, the doctor's second robot, Black Bomberman, suffered a programming error that clearly omitted that part. A power-hungry maniac with aspirations for world domination, Black kidnapped Lisa (the doctor's only daughter) and holed itself up in the intimidating mechanical castle. Bomberman begins his long journey towards the castle to rescue the good doctor's daughter, and to put a stop to this malfunctioning misfit!
