The Ultimate Impostor has an incredibly kind and caring personality. They are also very proud of their body size. They greatly enjoy food (especially fast food) and have a lot of knowledge about nutrition. They will do anything to get their job done when they are impersonating somebody, and will assume their personality easily. They can adapt to any situation and assume the appearance and mannerisms of anybody without difficulty, and are indistinguishable from the person they are disguised as.
