Music Meister

 Music Meister is a villain from Batman: the Brave and the Bold. He was created exclusively for the series, and is voiced by Neil Patrick Harris.

History
Music Meister makes his prescene known to the world when he used his hypnotic voice to control fellow villains Gorilla Grodd, Black Manta, and Clock King, as well as Aquaman, Green Arrow, and Black Canary. Using his six mind puppets, Music Meister hijacked a government satillite he planned to use to project his voice across the world. His actions caught the attention of Batman, and his eyes caught hold of Black Canary. When he failed to win her over, Music Meister decided to do away with her and Batman, by tying them up in a death trap. But in his arrogance, Music Meister underestimated his opponents, and, despite help from a mind controlled world, was defeated with one punch by Batman.

Powers
Music Meister's singing voice contains a hypnotic frequency that allows him to control minds.
