The origin of Super Villains: Fiddler
https://en.wikipedia.org/wiki/Fiddler_(comics)
The Fiddler is a fictional supervillain appearing in American comic books published by DC Comics, as an enemy of the first Flash.
The Fiddler made her live appearance on the fourth season of The Flash played by Miranda MacDougall. This version is a female version who is actually not a villain and a budding country music artist.
Fiddler first appeared in All-Flash #32 (December 1947/January 1948) and was created by Robert Kanigher and Lee Elias.
Earlier, a character with the same name, though only superficially similar, appeared in multiple Action Comic episodes of the Vigilante (starting with Action #59, April 1943 cover date.)
The Fiddler's history was changed somewhat during the Crisis on Infinite Earths.
The Fiddler started out as a thief who was arrested in India and sent to jail. While in prison, he met a fakir, charming a snake in his cell, who taught him the "mystic art" of Indian music. For the next five years, he learned the fakir's secret and made a crude violin made of material he could scrounge in the prison. He developed the ability to use his violin to play sounds that could either hypnotize others, shatter objects, or create barriers.[1] After the fakir declared his student had surpassed him, he used the instrument to hypnotize the guards to open their cells and he and the fakir escaped. He then murdered the fakir and the merchant who had him arrested in the first place.
