Memory parasite
A memory parasite was a lifeform that manipulated the memories of those around them, making them believe they were always there.
Aoife Fitzgerald perceived memory parasites as "the worst", and remembered when SIGNET fell victim to "Aaron or Alex or something", a memory parasite who made them think that he was always part of the team and then tried to "have sex with people."
Later, Charles Zoltan said there was "an infestation of memory parasites in Whitehall." This infestation caused other governmental organisations to be held up, forcing SIGNET to deal with a thermonuclear missile. After the Noodle Man inserted himself into the narrative as a result of the Noodle Incident, Zoltan began to believe that his teammate Jae-Sun was in fact a memory parasite. Zoltan also shot Choppy the Gonzales in the head be;lieving to be a memory parasite. Unlike many other Presidents of the United States, Richard Nixon, who came to help, was categorically not a memory parasite.
