Chief Warrant Officer Zoey-149 is a SPARTAN-II Super soldier whose body suffered from complications resulting from a part of the Augmentation procedures which caused permanent optical damage. She was designated as a 'washout' of the program and placed into ONI's ranks - primarily working between the Watershed division and Materials group. Through advancements made in the fields of both medicine and bio-technology regarding the blindness she suffered, Zoey was rehabilitated and put forth for active duty, serving aboard the UNSC Infinity as part of Fireteam Pteranodon whilst testing new technology constructed by both the Watershed Division and Materials group.
