3. The Enchantress
One of Thor's earliest foes from way back ... Amora the Enchantress's prime motivation is the seduction of Thor. Thor has proven himself to be one of the few men who can resist her tempting wiles, and like any bad girl, she can't resist a challenge. The thing about Amora is, she's obsessed. Obsession is a majorly bad characteristic for anyone to demonstrate, but in a spurned woman of Amora's type, well; you've got a super-powered, Asgardian god-like case of Fatal Attraction here. To be fair though, the only way she's ever going to pay any attention to you is if it's going to help her to persuade Thor to look her way. Amora is beautiful, conniving and possessed of an extremely powerful array of magical abilities that rank her one of the most dangerous in this bad girl list. Not only is she Asgardian, which makes her super-human, but she's also demonstrated incredible resourcefulness and imagination in developing new tricks to enthral and dominate Thor. You wouldn't get a valentine from this bad girl. As a mere mortal that dwelleth amongst the dust-laden hovels of Midgard, thou wouldst be fortune-blessed indeed to simply garner the slightest glimpse of the sun-dressed golden locks of the fairest of Asgardian womanhood.
