STORY The high school baseball player from Megalocity High was hailed as a future prodigy, a super high school-level genius slugger, but one day he lost his life while trying to save Dr. Yamada Belmara and his granddaughter, Rinda Yonekura, who were attacked by the massive criminal organization Death Guitar... However, the great criminal organization Death Guitar feared that even in death, the courage power of that high school baseball player had blasted through the Neo Drum Justice Gauge and sent the ball flying over the fence, so they performed evil cyborg Drummer surgery on him in order to exploit that justice power for their own wicked ends. But the moment he was revived as an evil cyborg drummer, he was rescued by Dr. Yamada, who had been captured and forced to cooperate by the massive criminal organization Death Guitar, and escaped from their hideout. The high school baseball player struggled with the conflict between the side of himself that was a baseball player and the side that was a cyborg Death Drummer (dissociative identity disorder), but through the surgery and treatment performed by Linda, the granddaughter who inherited Dr. Yamada’s genius brain, he was able to integrate both sides and acquire a single identity as Iron Gaban. Iron Gaban fights by transforming his drumsticks into a Metal Iron Bat in order to crush the evil that plagues the world and defeat the massive criminal organization Death Guitar!!!!! (By the way, the Metal Iron Bat is designed with spikes on the snare and toms, inheriting just the right balance of both drumming and baseball. Its shape also resembles Kyoto Tower, but that is because it serves as a fast-breeder reactor that amplifies the Galaxy Monster Energy caught by Kyoto Tower, the base of Iron Gaban and Linda. Furthermore, perhaps because of the evil feelings incompletely implanted in him by the massive criminal organization Death Guitar, he has no hesitation whatsoever in full-swinging the Metal Iron Bat at an enemy’s temple.) Meanwhile, in order to oppose the existence of Iron Gaban, the massive criminal organization Death Guitar secretly abducted and imprisoned the high school baseball player—an ultra high school-level genius pitcher whose skill was said to be Major League class—on the day of the Koshien final, and subjected him to evil cyborg surgery to turn him into Mega Bass. The regret of having been unable to fulfill his dream of winning Koshien merged with the evil cyborg feelings implanted in him, and he was revived as Giga Bass, who had returned to this world to destroy it in a form even Death Guitar had not anticipated. Giga Bass, having gained power so great that no one could control him, pressed the MEGA BASS button on the stereo mini component built into his body, and by thermally boosting the shoulders and elbows that, for a pitcher, are his lifeline and would otherwise crack, shatter, and be destroyed under the strain of his own power, he completely shattered the control panel in his brain and awakened as Iron Rider, able to throw balls that would tear the earth apart...
