Another totally not intimidating villain: That druid woman from Troll 2. First of all, I dig the librarian look (to be fair, she does radiate an aura of \"never procreate\"). Then her evil villain power: Asking you to drink green shaving foam that could turn you into a plant thing. Minions: Children in potato sacks, wielding sticks and really bad rubber masks. How to defeat her? Hold hands. Or, you know, simply not drinking the broth because she really can\'t so anything.
Only thing remotely intimidating about that one is a) the voice and b) the acting.
By the way, do NOT see Troll 2. It is without a doubt the worst movie ever.
