Shizzandra (1994)

A villainess plots to steal a valuable jewel. For her evil plans to succeed she requires the services of a woman with super-strength. She orders the kidnapping of an innocent girl and, using ancient Egyptian techniques - and plenty of tight bondage - forces the captive to arouse her secret strength that has been locked in the subconscious. Unfortunately for the villainess, the superheroine, now named Shizzandra, escapes once she realizes her own super-strength.
