Biography
Background
While he doesn't appear while the original Dragon Ball series takes place, his bio mentions that back at Age 740 Myuu (who was apparently a native M2 resident) found the Tuffle made parasite that had contained the Tuffle King's memories and had been taken over by this parasite, that would eventually become Baby, and then began executing his plans for universal domination.
Dragon Ball GT
Black Star Dragon Ball Saga
To reach his sinister goal of control through the universe, Dr. Myuu creates a powerful enforcer named General Rilldo and tries to gather the Black Star Dragon Balls to use them to complete his ultimate creation, Baby. He also hires Dolltaki, the leader of the Luud Cult, for whom he creates a giant Machine Mutant called Luud, as well as Cardinal Mutchy Mutchy and Leon.
Baby Saga
When Goku, Pan, and Trunks arrive on M-2, Dr. Myuu masterminds the plan to build the ultimate Machine Mutant out of them, but the gang gets past General Rilldo and foils Dr. Myuu's plans. When Trunks reveals Baby to Goku and Pan, Dr. Myuu reacts horribly, believing lowlifes such as Trunks should not look at his amazing creation.
Believing they have destroyed Baby, Dr. Myuu escapes but is killed when Baby bursts out of his body. It is revealed then by Baby that it was Baby who programmed Dr. Myuu, and not the other way around.
Super 17 Saga
Dr. Myuu later teams up with Dr. Gero in Hell and creates a mutant machine duplicate of Android 17, who controls the original Android 17 and converges their powers together to set a rift between Earth and Hell. Hell's Android 17 and the two scientists escape, after which the two Android 17s eventually fuse together to become Super 17. Due to Myuu changing Super 17's programming behind Gero's back, Super 17 betrays and kills Dr. Gero during Super 17's dominant battle against the Z Fighters. Super 17 then proceeds his domination against the Z Fighters (including Super Saiyan 4 Goku thanks to his absorption field ability) to the point that Dr. Myuu truly believes he can take over the universe until Android 18 shows up and appeals to Super 17's sense of self.
In anger at Android 18's apparent influence, Dr. Myuu orders Super 17 to destroy Goku and Android 18 with his Shocking Death Ball, calling out his manhood and courage in the process. However, Super 17 is agitated by this, refusing to be controlled again, and turns against and destroys Myuu with the attack instead.
