Dissociatives, Villains with Dual Personalities or Villains with Multiple Personalities are characters who have been diagnosed with or display signs of dissociative identity disorder (also known as multiple personality disorder) - these individuals have a fractured psyche that makes it appear like they have more than just one personality; one or more of these personalities is seen as obviously malicious or dangerous (at least in fiction). Dissociative Identities can occur from different circumstances: mental illness (e.g Norman Bates), failed experiments (e.g Green Goblin) or traumatic events (e.g Fliqpy).

Do not add beings who are possessed by demonic entities, Aliens or other beings (for those cases use Possessed/Brainwashed or Pawns) - also do not confuse them with Alter-Egos (as they are simply alternate personas made by the villains to disguise themselves and perfectly sane individuals may have Alter-Egos for a variety of reasons such as keeping their identities secret, much like how traditional heroes wear disguises: dissociative characters literally see themselves as two or more distinct individuals and are not in control of any changes). They can even be similar to but still not the same as villains who are Fragmental given that the evil part of the individual's mind as a whole is just a splintered fraction of who the character really is. However, if a Dissociative is forcibly split from at least one of their "other selves", they may overlap with Fragmentals and can overlap with Alter-Egos if a different personality is an entirely separate individual within the same person.

This kind of villain generally doesn't count as Pure Evil given they have no control over their actions due to their illnesses. However, some can qualify if:

  • A) The Alter ego of the character meets all criteria and every heinous crime is traced back to said ego (e.g. Yami Marik).
  • B) The split personalities and original personalities are all heinous and show no regret towards their crimes, even being capable of knowing what their split personality did (e.g. Norman Osborn as both his original self and Green Goblin persona).
