Dr. Myuu

Dr. Myuu is the first main villain of Dragon Ball GT and creator of the next two main villains, Baby and Super 17.

Creating Baby
Dr. Myuu is first introduced as an evil scientist who seeks to use the Dragon Balls to create the ultimate Machine Mutant. To do so, he created General Rilldo to act as an enforcer who could obtain the Black Star Dragon Balls for him, which had been scattered throughout the universe because of a wish made by Emperor Pilaf. However Goku, Pan, and Trunks managed to destroy Rilldo and foil Myuu's plans. He escaped, only for Baby to burst out of his body and kill him. Baby then revealed he had programmed Dr. Myuu, not the other way round.

Alliance with Dr Gero
Dr Myuu later teamed up with Dr. Gero while in Hell and the two worked together to create a duplicate of Android 17, named Hell Fighter 17. This duplicate succeeded in brainwashing 17 and the pair of doctors used their combined powers to create a portal out of Hell, which they and their new creation escape through, along with every other past villain. Once Hell Fighter 17 fused with Android 17 and became Super 17, Myuu revealed he had changed the androids programming so that it would kill Gero, which he did. Super 17 then managed to defeat all of the Z Fighters, even Super Saiyan 4 Goku, with help from his absorption field ability, which convinced Myuu he could finally take over the universe. However Android 18 appeared and managed to get into Super 17's head, causing Myuu to order his creation to attack with his Shocking Death Ball. However the android was angered by this and used that attack on Myuu, killing him yet again.

Trivia
