Personality
Peter is a weird Elmo creature in Episode 1, but changes into Peter Pan in the next two episodes. Peter is an annoying squeaker who is very stupid. He, along with Shadow, are not very efficient when it comes to escape planning and social interactions in the prison. He seems to be a psychopath, participating in violent behavior with everyone in the prison, with strangely, no consequence.
