This article contains a list of minor characters in the American television series Prison Break. The listed characters are those who are played by guest stars. The characters are listed alphabetically by their last name or by the name which appears in the episode credits.
Jonathan Krantz, or the "Pad Man" to fans (played by Leon Russom), is the main antagonist in the series. He is the leader of The Company and holds the rank of General. He appears only fleetingly in his first two seasons, as William Kim's shadowy superior and architect of Michael Scofield's incarceration at Sona. The character plays a large and important role in season 4, appearing in every episode although being credited as a guest star instead of being in the main credits. In earlier seasons, he is identified by his tendency to issue orders on notepads, to avoid being recorded, a tendency which he fully abandons by the fourth season. In his appearance in the season 4 premiere, he discovers that James Whistler, the man Michael was forced to break out of Sona, is a traitor. After Whistler's betrayal, he orders drastic measures to be taken against The Company's enemies, dispatching the ruthless assassin Wyatt to kill anyone and everyone necessary to achieve those ends. Meanwhile, in the initial stages of his season 4 character arc, the General is not aware of Michael's teams's efforts to steal Scylla and most early episodes of the season deals with him planning a sinister operation in Laos, and interacting mostly with Wyatt and the Scylla Cardholders. As the season unfolds, Michael and his team eventually learn of the General's identity and his place as the leader of The Company, and he gradually comes to the forefront of the plot with increased screen time with the protagonists as a consequence. When it is reported that Agent Don Self did an identity search on the General, he seems to be very shocked and gives Wyatt the order to keep an eye on Self. In "Safe and Sound", it is revealed to the viewers that the General's name is "Jonathan Krantz", as seen from the images of him. Learning that the General has one of the Scylla Cards, Michael's team plan an attack against his limo in "The Price". Due to the betrayal of team member Roland Glenn, the General is alerted and the attack is not successful.
