What happens when you have a PuritySue, and remove the Purity part? You get a Neutrality Sue. This one, much like the AntiSue, is not afraid to be flawed. In this case, however the distinction made is not that the character is trying to be flawed, but that any flaws are {{Hand Wave}}d by them being [[GreyAndGrayMorality neutral characters]]. But, here's the interesting part... this means they have license to do ''anything''. Want them to save a kitten from a tree? They can. Want them to [[KickTheDog kick the kitten]] in the very next moment? They can, with no contradiction of character.

In terms of personality, this trope usually is either [[EmotionlessGirl devoid of emotion]], or varies from [[SugarAndIcePersonality deadpan to emotional]] to [[ChaoticStupid outright]] [[{{Yandere}} unstable]]. The Neutrality Sue basically thrives on being somewhere between extremes, and thus able to do everything in between.

Related to the FixerSue, a combination of PuritySue[=/=]VillainSue, and in some cases the SympatheticSue (if backstory and personality flaws are played out heavily). Compare CloudCuckoolander.
