However, after his defeat, he regains his former memories, and realizes that he and the other Dastardly Bombers had been brainwashed by Buggler when they were resurrected. On Planet Scrapheap, Plasma Bomber tells them that his objective is to overthrow the organic life-forms who created them, because they treat them like garbage and discard them on a wasteland planet when they tire of them. The Bomberman Brothers work their way from planet to planet toward the center of the solar system, defeating each Dastardly Bomber in combat and freeing the planets from their grip, overcoming their own limitations in the process. White vows to defeat them, but he must force his apathetic siblings to come with him.

They receive a transmission from Buggler, who states that his Buggler Army has taken over the five planes of the Starry Sky Solar System as part of his mission for galactic conquest, and insists that anyone who is brave enough to oppose him should come and face the Five Dastardly Bombers. Meanwhile, on Planet Bomber, the Bomberman Brothers are slacking off, despite their eldest brother White's insistence that they train diligently. He bids them to join him in a quest for revenge.

On Planet Scrapheap, the evil Buggler appears and uses dark powers to revive five scrapped robotic life-forms, the Five Dastardly Bombers.
