Fictional character biography.
"Batman: The Brave and the Bold".
The Music Meister, a villain capable of controlling others through song, first appeared in the "" episode "Mayhem of the Music Meister!", voiced by Neil Patrick Harris. In order to hijack a United Nations communications satellite, he induces Black Manta, Gorilla Grodd, Clock King (who were there to steal the satellite themselves), Black Canary, Green Arrow, and Aquaman (there to stop the other villains) to commit the crime for him, launching it into space after they install a device inside it. ("I'm The Music Meister") During the song, Music Meister relates his origin:
When Batman intervenes, Music Meister orders his thralls to attack the hero, which they do in a dance style reminiscent of "West Side Story". His plan successful, the Meister escapes by forcing his captives to dance towards the rocket blast, leaving Batman to rescue them rather than apprehend him. Meister flees to an empty opera house where, in a reference to "Phantom of the Opera", he plays the organ to a cardboard audience. Batman tries to capture him in a cross-town chase, but Meister releases inmates and villains from Iron Heights Penitentiary and Arkham Asylum ("Drives Us Bats"). Having heard Black Canary sing about her unrequited love for Batman ("If Only"), the Meister falls for her, but not enough to give up villainy. Canary, in turn, firmly rejects him.
Meister captures Black Canary and Batman and puts them in a death trap ("Death Trap"). However, they escape just as Music Meister uses the satellite to hypnotize the world with his music ("The World Is Mine"). When Black Canary becomes his slave, Batman tricks her into singing as high as he. He then seizes the Meister's microphone and uses the satellite to transmit Canary's sonic scream to break the mind control and defeat the Music Meister.
"Batman: The Brave and the Bold" (comics).
The Music Meister later appeared in "" #16 (April 2012). After Bat-Mite became instantly infatuated with Batgirl and tried to impress her with his magic, conjuring up scenarios from the comic books he has read, he teleported the Music Meister, Pied Piper, and another musician for entertainment. The Music Meister tried to take control of Bat-Mite, but was knocked out before his powers could take effect.
Powers, abilities, and equipment.
The Music Meister is a metahuman with the ability to cause every living being who hears his voice to burst into singing and dancing as though they were in a musical. In this hypnotic state, they are compelled to obey the Meister's commands, including those that endanger themselves. His influence is effective even when he is several feet away or in another room. The effects of his vocal hypnosis can be blocked out using ear plugs. The deaf and the hearing impaired are also immune to his powers. Victims recover their normal faculties within moments after the Meister departs or is rendered unconscious. In addition, he appears to have the uncanny ability to change his outfits extremely quickly, each of which represent different eras in music history, such as Elvis Presley's leisure suit and Cab Calloway's zoot suit.
Music Meister carries a rod-shaped weapon resembling a conductor's baton that fires energy blasts shaped like musical scores. For transportation, he rides a fast, highly maneuverable scooter in the shape of two beamed eighth notes.
