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 who also voiced Dr. Blowhole.

He is loosely inspired by the Music Master, a one-shot villain used in the Justice League episode Legends, one of the villains of an alternated universe who turns out to be a creation of the mutant Ray Thompson (incidentally, Ray was also voiced by Neil Patrick Harris). Like the later villain, Music Master has red hair and a gap in his teeth, but the similarities end there.

History
Music Meister makes his presence 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 plans 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. It also has the unusual ability of forcing his victims to express themselves only through song and dance, as if they are in a musical. He mentions that he discovered this power as a child and used it on those who bullied him for singing in choir.

His weapon of choice is a cane/baton outfitted with a microphone that allows him to amplify his voice, and shoots sonic blasts that resemble sheet music. His mode of transportation is a motorcycle shaped like a beamed note. This can also convert to a scooter shaped like an eighth note, and to a helicopter.

Dress
The Music Meister changes outfits and hairstyles frequently over the course of the episode, having an extensive collection of ensembles based on different styles of music. One thing that remains the same is his sheet-music styled glasses. His outfits include -
