Nobody

One of Nobody's core themes (and possibly the only theme that is consistent among all his appearances) is "Mystery.". Nobody has tons of varying interpretations. Nobody is often involved in everything. He has his fingers in a lot of pies. When Nobody appears in a story, it is always significant. And, there is often no real way to fight against Nobody. Usually, even the almighty Foundation has to just allow him to do what he wants. Nobody is (likely) operating alone. Basically, the idea was to take the term "Nobody" as literally and dramatically as possible. This idea was inspired by how, in previous appearances, Nobody is able to blend in and move about with unprecedented freedom, seemingly separate from the world around him. In short, in this conception, Nobody is unable to affect the world around him in any significant ways. He cannot be the origins of any change in the world. Anything that he tries to do will inevitably end up as if he was never involved. His goals are to try to affect something, so that he feels that his life will have meaning. He has insane IQ and EQ btw. "Nobody" is self-aware and knew themself is just fiction created by a person.
