Mandrill is another who "rapes" through mind control.
Sabretooth supposedly raped Silver Fox.
In modern retellings, Belasco wasn't just hocus-pocusing over young Illyana, but raping her. And he certainly raped the original Beatrice.
D'Ken raped Cyke's mom.
Lincoln Slade, the Phantom Rider, raped Mockingbird, but he used drugs and hypnosis to make her more pliable.
Kaptain Brtion and Sat-Yr-9 liked to rape, in tandem with mind control, but I'm sure that was optional. Psylocke killed the former when he tried with her.
I'm quite sure it's been suggested that Sugar Man raped a lot. Can't recall the examples off hand though.
Coach, from X-Force/Statix, attempted to rape U-Go Girl. She shot him for that.
Joe MacTaggart raped Moira, and this was the explanation for Proteus' madness. Don't accept that last part, but well...
Has Mandrill ever used his powers to rape anyone? Obviously, having the power to mind control women could very easily be used for that purpose, but I don't think he's ever done so. As far as I know, he's only used his power to make women commit crimes for him, not to have sexual relations with him. And for what it's worth, Dan Slott specifically stated that Mandrill was not a rapist over on the Spider-Man board.
