1. Of course the mask turns invisible when he's invisible. He is able to turn invisible while wearing clothes, he just chooses to go around naked cause it's more arousing to him, and he wears the mask to conceal his face. If there are any other issues with the method, please read "Sean Renaud"'s first reply, he explains it perfectly.In invisible mask? If he's invisible and the mask isn't, that's rather a giveaway -- look, a floating mask! If the mask is invisible and he materializes, he's not masked -- look, it's Wilhelm!
But if he DOES switch off invisibility in a situation allowing his capture and punishment, that makes him an idiot. If he's a non-idiot and is threatened with capture he need merely go invisible again, and escape.
Okay, he's not a rapist. He's a nice, moral guy with quirks. Right. He never thinks of exploiting his power / ability beyond playing flashing pranks. Right. Are readers going to buy that he's a sweet one-trick dumbass?
EDIT: As you might gather, I'm not a big fan of stories about people with 'powers'. Nothing personal.I tend to approach those as farces, like Randy Randy (The Pornomancer). That's just me.
2. Of course he knows he could do more to his victims with his power, but chooses not to. I never said it made him a decent moral guy, I just said he was a prankster, and a flasher ONLY.
3. He would turn off his invisibilty only to flash his targets, the same reason normal flashers open their trench coats. But if you still have issues with this, you could switch up the method and say instead of having the power of invisibility, he uses some sort of object that gives him the power.
