Lorelei Circe (The Siren)
The Siren
A deadly super villianess who is able to put any man under her spell by singing a note of three octaves above high C. In the series she was able to get Commissioner Gordon to sneak into the batcave via the boot of the batmbile, then entranced Bruce Wayne to sign over all his fortunes to her and even made Chief O'Hara jump into Gotham lake.
When she almost fell off the top of Wayne Headquarters building (pictured above), Robin promised to pull her up only if she sang an antidote note to release all those still under her spell. She did so causing her to loose her voice for good.
She appeared in two episodes during the third season, including a team up with the Riddler during her first episode. The Siren's other associates/thugs were Allegro and Andante who had to keep putting on ear muffs/headphones to block out Sirens entrancing note. Her only lair was the "underground grotto".
Before being the Siren, she was simply Lorelei Circe a world famous singer and musician (played the harp) but unfourtunately decided to use her voice to persure a life of crime.
