Music Meister to Threaten Supergirl and The Flash in Musical Crossover

Executive producer Greg Berlanti has revealed who the villain will be to trouble Supergirl and The Flash in the upcoming crossover episode… which will be a musical.

“It is going to be the Music Meister,” he told reporters during the recent Television Critics Association press tour. “We’re finishing writing the script this weekend.”

The Music Meister uses his singing voice to create a pitch so high that it hypnotizes people. In their state of hypnosis his victims are forced to sing and dance.

The character was voiced by Neil Patrick Harris in “Batman: The Brave and the Bold” animated series, leading some people to speculate that he could be cast to play the live action role on “Supergirl”, but no casting has yet been announced.
