Satan Girls Prisoners

Satan Girl originally appeared in the 30th Century and took on the Legion of Superheroes. She was unstoppable until they realized Satan Girl was Supergirl who had been turned evil by Red Kryptonite. As she has all of Supergirl's powers it would have been easy for her to travel to the 1970s and just for fun capture Wonder Woman and Supergirl. Using Superspeed she could have surprised and tossed Supergirl into a box filled filled with red solar radiation and chloroform fumes. Then she would chloroform Wonder Woman when she tries to help. The heroines would wonder who she was before she went back to the future.
