| First Appearance: Conquest of the Planet of the Apes
Last Appearance: Battle for the Planet of the Apes
In Conquest of the Planet of the Apes, Kolp was Chief Inspector of the 'State Security' secret police organization under Governor Breck, displaying himself as sadistic, but in a detached, matter-of-fact manner. Kolp and Inspector Hoskyns interrogated Armando, which Armando ended by throwing himself through a high window, rather than confess what he knew about Caesar under hypnosis. Later Kolp tracked down the originating shipment that had carried Caesar to Ape Management; he deduced that Caesar had sneaked himself into the shipment, to appear to have wild origins. Kolp was also present when Breck interrogated Caesar, strapped to an electroshock table, and he gave the order for Caesar to be electrocuted, once it was proven that Caesar could speak and reason.
Kolp survived the Night of the Fires, when the apes revolted and took over, and also the nuclear war mankind then unleashed, all but destroying themselves in doing so, while the apes escaped to the wilderness. Much of the city's governing staff were relatively safe in underground fallout shelters and bunkers; nonetheless, lingering background radiation began to cause physical mutations in the survivors. By the fifth movie, after Breck's death, Kolp had inherited the remnants of the human population of the city and styled himself 'Governor'. He was paranoid about the apes returning to finish the destruction of humanity.
Twelve years after the end of the war, Caesar, Virgil and Mr. MacDonald revisited Ape Management (now called the Forbidden City by the apes), in hopes of finding old video recordings of Caesar's parents. Kolp's agents discovered their presence, and Kolp assumed they had come scouting for things to loot or reconquer. Shots were exchanged as Caesar, MacDonald and Virgil fled, and scouts tracked them back to Ape City. With the city's location known, and jealous of the relative health and prosperity of the apes and the humans living with them, Kolp decided to marshal his forces and conquer Ape City. At this point, Kolp was not only mad, but also vengeful. When his second-in-command Méndez pointed out to him that attacking the Ape city would constitute a direct violation of years of peace, Kolp's answer was that of a deranged state-of-mind: "Yes, well things have gotten rather boring around here now, hasn't it."
Kolp supervised the attack personally, telling his troops to leave Ape City looking "like the city we came from," and to do their worst. When it appeared Caesar was defeated, Kolp personally taunted him with a revolver, nearly breaking Caesar's spirit, until a cry from his wife Lisa restored it. Beaten and dying in the ape counterattack, Kolp sent back the order for the mutants' last-resort weapon, the Alpha-Omega nuclear missile, to be fired at Ape City. Kolp was killed while retreating, by Aldo and his Gorilla troops. His lieutenant, Méndez, subsequently cancelled the order, deciding the best thing to do was to retreat and live in peaceful coexistence with the apes and above-ground humans.
- The original ending of Conquest was altered after it was judged too gruesome by test audiences. The key difference was that in the first version, Breck was killed by the vengeful apes. In the released version with newly-filmed ending, Caesar spares the life of the Governor to show the compassion that the humans lacked. (The original ending was finally restored in the 2008 Blu-Ray release of the movie.) While this left open the option of Breck's return, which was in fact written into early scripts for Battle for the Planet of the Apes, actor Don Murray wasn't interested in returning to the role. Instead, the part was reworked to allow Kolp to become the new Governor of the mutant city after Breck had died off-screen.
- The early scripts for Battle all use the name 'Modern City' for the city in which those events take place. They also refer to Breck as having been 'City Governor', rather than the Governor of a state.
- The 'Alpha-Omega Bomb' scenes in Battle were removed from the officially-released version in 1973, in order to avoid the suggestion that the events of Battle would inevitably lead to the destruction of the world shown in Beneath the Planet of the Apes. The scenes were, oddly, restored for TV broadcasts in 1975, but did not receive an official release until included on a Japanese Laserdisc (in the early ‘90s) and on North American-region DVDs in 2006.
- Marvel Comics' adaptation of Battle was based on the early scripts of that movie (writer Doug Moench claimed to have not seen the later Apes movies that he adapted to comic format), and consequently featured Governor Breck as the mutant leader. The role was the same as that of 'Governor Kolp' and at the end of that version, Breck (rather than Kolp, who doesn't appear at all) is shot dead by Aldo after the Ape-Mutant battle. Uniquely, Marvel also published an original story set between Conquest and Battle which detailed how Breck, Mendez and Alma managed to escape from Caesar's Ape settlement after some years as slaves, and returned to the radioactive city (one year after the great mushroom cloud had destroyed it) where by the time of Marvel's Battle adaptation, they had become severely disfigured.
- The novelization of Conquest was based on the script of that movie, and consequently saw Governor Breck killed at the end of Caesar's revolution. The novelization of Battle therefore required Kolp to fill the role of mutant leader, as in the movie.
- MR Comics' Revolution on the Planet of the Apes comics detailed the aftermath of the events of Conquest. Here, Kolp and his associates Mendez and Alma launched a rescue operation to free Breck - a prisoner of the apes in the days after his capture - but in the ensueing battle, Breck was crushed beneath a massive bomb.
- Malibu Graphics/Adventure Comics' Forbidden Zone comics featured 'Kolp', who exiled the mutant Mendez X from their underground city before sending General Jaekel to kill him. It's unclear if he was a descendant of Governor Kolp, or how the Mendez Dynasty regained the leadership of the mutant city.
- An early draft script of Conquest gives Kolp the first name of 'Arthur'.
- The comic book miniseries Revolution on the Planet of the Apes, from Mr. Comics, calls him 'Vernon Kolp'.
- He is the only villain other than Dr. Zaius to appear in more than one Planet of the Apes film.
