Krampus
A being calling itself Krampus was a member of the Pantheon of Discord. He attempted to change history by removing Amy, Rory and Mels.
HISTORY
This member of the Pantheon found its way into reality by a Time Field in Leadworth. He managed to fully enter reality by getting Veronica-the spoiled daughter of the Mayor to take his "gift for her". There he proceeded to send his servants to capture Amy, Rory and Mels-when they failed, he personally captured them and took them to the library. In order for him to fully have power he needed Veronica's wish, when at first she didn't want to he persuaded her to do so by showing her an image of Amy's Petrichor brand. However his plan was foiled when Amy told Veronica that her hands were dirty-and what she thought was her doll was in reality a lump of coal used to coax Veronica to bring him to Leadworth, she threw it back into the mirror as Krampus and his goons were forcibly dragged back into where they had originally came from, presumably for good.

APPEARANCE
Krampus while appearing to Veronica and the others appearing to be dressed in the attire of Father Christmas, though with the colours reversed-to the point where he claimed he was standing in his shadow. Briefly the members true form was revealed as a tall red being with a long tongue and ghastly features. He also spoke with a German accent.
PERSONALITY
The Pantheon member whilst attempting to coax Veronica seemed to be like Santa Clause-he appeared to be a kind man to Veronica telling her he was her uncle with a big smile, But in truth he despised the child and was only intending to use her to get rid of them angrily telling her "Just say ze vords [you] spoiled brat!"-He hated returning to his point of existance as he screamed as he was dragged back into it. Krampus appeared to truly resent the young Amy and Rory as he angrily told them their own future-intentionally realising that he had told them the truth. The being however was flawed at explanations as he sometimes awkwardly laughed when Veronica knew he wasn't her actual uncle or when she heard him annoyed with her. (COMIC: Imaginary Enemies)
BEHIND THE SCENES
It is currently unknown if this being is The Krampus from Doctor Who Adventures.
It is also unclear whether or not this being is actually the same species as the Trickster as they're both defeated by the link that brings them there being rejected or if it is a similar species.
