Completing the Circle: Trying to Figure Out Supergirl #18
Richard Pryor tries to kill Superman in Superman III.
Midriff Supergirl learns from her father that she must kill Superman somewhere around Supergirl #16.
Belly-Covered Supergirl decides she must kill Midriff Supergirl in Supergirl #18. But who is she really? The Real Supergirl? An imposter? The answer, if you look closely, is obvious.
She is clearly Rain Pryor, daughter of Richard Pryor, in a blonde wig. And thus the cycle of killing is closed.
