"I had to get through the worst, to prove I was the best."
― William Bishop

Lieutenant Colonel William Bishop (ウィリアム·ビショップ) is the leader of the United States Air Force Warwolf Squadron. He is a flight veteran with many years of experience in various conflicts.

Bishop is the main player character in Ace Combat: Assault Horizon, leading Task Force 108 through the game's events.


William Bishop was born in California in the United States.[1][2] Nothing else is known about his early years.

Early combat and testing

As a fighter pilot in the United States Air Force, Bishop saw his first combat in the Bosnian War as a rookie under callsign Wolf 4 in Wolf Squadron. He later served as a squadron commander in unspecified conflicts in Iraq and Libya.[4]

By the 2010s, Bishop had earned the Lieutenant Colonel rank. He was assigned to be a test pilot for Righteous, a modified F-22A Raptor in development to be a UAV.[4]

Bishop "dying" in his dream

While testing Righteous, Bishop was offered the role of squadron commander in Task Force 108, which was fighting the SRN insurgency in West Africa. Frustrated with the lack of combat in being a test pilot, Bishop accepted.[4]

One night soon after arriving in the conflict zone, Bishop suffered a nightmare where he and Warwolf Squadron were defending Miami from an attack led by a fighter pilot with a shark on the aircraft's nose. Bishop was shot down in the nightmare, and when the shark-nosed aircraft attempted to hit him head-on, he abruptly woke up in a sweat.[6]

Concept Art



Early image of Bishop with facial hair

  • In initial promotional media for Assault Horizon, Bishop (and his wingman, Guts) was depicted with some facial hair. However, USAF policies do not permit facial hair, so this was removed later in the game's development.
  • Bishop is the first player character in the Ace Combat series whose face has been unambiguously revealed. All prior player characters were never seen from the front, or had their faces obscured.
  • Bishop is the second player character in the Ace Combat series to have voiced lines, the first being Phoenix in Ace Combat 2 landing sequences. (Ace from Ace Combat Advance was also a speaking player character, but he did not have any voiced lines.)
  • Bishop is the highest-ranking player character in the Ace Combat series. Other player characters either did not have their ranks revealed, were no higher than Captain, or their ranks were dependent on gameplay.
    • Despite his rank of Lieutenant Colonel, other characters repeatedly refer to him as "Colonel" in shorthand. This is also commonplace in the real world.[7]
  • Bishop's age is a subject of confusion. Official media confirms that Bishop is 37 years old at the start of the game's events,[1][2] which means his year of birth is either 1978 or 1979. However, he took part in the Bosnian War,[4] which ended in 1995, when he would have been 17 years old at most.
  • Jim DeFelice based Bishop's characterization on an F-105 Vietnam War veteran he personally knew.[5] He also drew inspiration from Lieutenant A.K. Waters (played by Bruce Willis) in Tears of the Sun.[5][8]
  • Bishop's name is likely based on Canadian ace William "Billy" Bishop.
