The illusive Jimmy is the only person that John trusts and does not torture. Jimmy is John's partner in crime because they both have the same goal: to rule the world. They thought that if they have the same goal then it would be a lot easier to collaberate then to try to kill each other. They both have very similar motives and thinking processes, just John has a higher kill count. This is because John is a lot more comfortable with being in public. However, Jimmy is more technological, thinking outside of the box. He too, however, does not have a known appearance. This is because he is always with John, and John can sense when people are near. He then proceeds to hide himself and the Jimmy with his shapeshifting abilities.
