Imposter!Sue

An Imposter!Sue or Imposter!Stu is an imposter of a canon character. Usually the character is so grossely out of character that mere possession or Suefluence does not explain their behaviour anymore. The proper way of dealing with an Imposter!Sue is to first locate the canon character that is impersonated. Often they can be found hiding in a plot hole somewhere. The agents can then procede to charge and dispose of the imposter as they would with a regular Sue. Impersonating a canon character is added as a charge.

A problem arises with Stus that try to impersonate Captain Jack Harkness. Jack can't stay dead and for some reason his imposters have this characteristic too. On their one encounter with a Imposter!Jack Harkness agents Emma and Tasmin decided to dispose of the imposter by taking him into Greek mythology and chaining him up next to Tantalos.
