KR Zero-One was a King Raven unit in the Coalition of Ordered Governments Air Corps that transported Chairman Richard Prescott and Prescott's two bodyguards, Rivera and Lowe, from Azura to the CNV Sovereign following the First Battle of Azura. Marcus Fenix noted that the Raven was newer and nicer than the remaining Ravens onboard Sovereign, and Dom Santiago wanted to give the Raven the "stranded welcome" by stripping it for spare parts. Soon after Zero-One's landing, a Lambent attack on the ship killed the deck chief, preventing the Raven from taking off. Delta-One was able to clear the landing bay of Lambent and raise the deck lift, allowing the Raven to take off.
