Both Purple Man and Moondragon have committed sexual assault, perhaps rape, against male victims. It was strongly implied that the Purple Man forced Swordsman II (Strucker) to acquiesce to certain acts while under PM's control. Similarly, Moondragon mind-controller Thor to be her lover. Without consent in either circumstance, I would call it rape.
I vaguely recall that the Puppet Master may have also crossed the line with a collection of female victims under his control. Empath may have as well. Seems to be a theme with villains who can control others' minds or emotions.
It's open for debate, but in my mind, Starfox has been acquitted of using his powers to interfere with consent.
when did moondragon do that?
