Music Meister

The Music Meister, a villain capable of controlling others through song, first appeared in the Batman: The Brave and the Bold 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:

Bullies used to pick on me because I sang in Choir.

But something very strange occurred when I kept singing higher.

The ruffians around me quickly fell into a trance.

And it was then with wicked glee I made those puppets dance.

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.

The Music Meister later appeared in Batman: The Brave and the Bold' #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 The Fiddler for entertainment. The Music Meister tried to take control of Bat-Mite, but was knocked out before his powers could take effect. This comic also offered up an origin story for the character, revealing he was the sole human survivor of an alien race consisting entirely of sentient frying pans, with the exception of Meister, whose real name was given as a combination of bizarre symbols.

The Music Meister made his first canon appearance in the one-shot DC Pride 2022 as a villain to Robin (Damian Wayne) and Green Arrow (Connor Hawke).
