16. Dexter (Arthur Mitchell)

The sole major villain in the Dexter series who operates under the Trinity Killer alias is Arthur Mitchell (played by John Lithgow). During "Hello Dexter Morgan," Arthur discovers who Dexter is and creates a role reversal from predator to prey. Arthur invents an appearance of family-man virtues, but his secret identity reveals him as a murderous serial killer. Arthur Mitchell stands as one of history's most remarkable antagonists because his average suburban persona allows him to pull off gruesome acts similar to the way Dexter operates with his secrets.
