Katherine Warren is a character in both Resident Evil 2 and the Resident Evil 2 remake.
Katherine is the daughter of Raccoon City's Mayor, Michael Warren. Left behind in Raccoon City by her father, she is left in the care of Chief Brian Irons. Driven insane by the outbreak, Irons instead murders Katherine, planning to stuff her body and keep it as part of his taxidermy collection.
Warren's body appears in both versions of Resident Evil 2 and its retelling Resident Evil: The Darkside Chronicles. She appears in the remake's Ghost Survivors DLC story "Runaway", which takes place outside of the main series canon.
