An Evil Twin or Evil Clone, also known as an Impostor or Doppelganger can be a deliberate attempt at creating an evil version of a hero by science or magic, or it can be an alternate version of a hero from a twisted reality or timeline. On some occasions, it can even be a literal twin of both the identical and non-identical varieties. Either way, it also connects to and overlaps with villains who are Incriminators.
They can also be Evil Counterparts, Foils or Copycats, meaning that they share some similarities to the heroes and their backgrounds, or are merely copying certain aspects of the hero or another villain altogether. Some of them take this a step further, to the point they would want to replace the hero altogether (Jill Roberts is a prime example to this).
