The Bitter Troll. Bitter Trolls are a curious cross-species. They can be trolls of any breed in their larval stages, but become Bitters after their previous activities are seen for what they were. What sets these trolls apart from other classifications is their behavior after they have been spotted and labeled as trolls. Angry, frustrated, and resentful about being "outed," the Bitter Troll will wage a campaign of indignant complaints intended to focus attention away from the troll and on whomever is responsible for identifying the creature. Often, a troll mutates into a Bitter just prior to becoming a Vulgar.
The Pretender Troll. The mutant offspring of Bitter Trolls, Pretenders become outraged when outed and attempt to channel their distress by mimicking their tormentors. Pretenders always "accuse the accusers," as they say, frequently (and falsely) charging that they are being wrongly labeled for merely dissenting in the course of a debate. Pretenders sometimes try to invent their own species labels and descriptions in desperate attempts to deflect and redirect the attention of other forumites. They may also ape the language and demeanor of their accusers (though they typically fail).
