* CompleteMonster: Richard Cross starts out looking like one and certainly heads in that direction, but has moments towards the end that show he really does regret his actions. [[spoiler: Roberto Portalegre]] plays this fully straight though, being completely unrepentant over killing Jessica and saying he would happily do it again if he could. Similarly, [[spoiler: Graham Lester]] has no appreciable moral qualms about [[spoiler: framing one of his own patients]].
* MagnificentBastard: Richard Cross, played by the incredibly charismatic Stanley Tucci. It's questionable through much of the show just how much he's involved in the murder, but he clearly knows more than he's saying and ''loves'' waving that in the heroes' faces. At one point, Teddy remarks that Cross' wife "has a good soul" - Cross smiles and offers "Whereas I am evil incarnate?". Teddy doesn't really disagree.
* TheWoobie: Neil Avedon.
