This week’s release of Scott Pilgrim vs. the World, in which Michael Cera has to do battle against Mary Elizabeth Winstead’s seven murderous exes, hopes to mine our collective, primal fear of the evil movie boyfriend: The guy who gets the girl — or got her once — but so totally doesn’t deserve her.

Others are altogether more disturbing — be they serial killers, kidnappers, or jaded supermen. We’ve gone back through film history and done the self-esteem-depleting work of researching cinema’s most iconic and evil boyfriends. Here they are, ranked in order of ascending evilness.
