Dr. Gero (, Dokuta Gero?) made himself into a cyborg by implanting his brain into a robot body. He first appeared with Android #19 to kill Goku. After #19 was destroyed by Vegeta, he fled out of fear and with the intention of activating Android #17 and #18. Once he activated them, they quickly rebelled on their creator. #17 kicked his head off and crushed it. In Dragon Ball GT, he helped Dr. Myu create Super 17, who later went on to kill both of them.
