Prohibit went to school with Photos and Sike, being good friends with them at that time. But between that time and now Peter has traveled the world and learned to have complete control over his powers something that he was never able to obtain in school. A majority of this time was spent learning kung fu allowing him to be able to face off against enemies directly. During one of his travels he got a call from Photos to come back to the institute to act as guidance counselor for the time being. Prohibit immediatley agreed and traveled back to his old school.
