One of XZ-500's most enigmatic warriors, file designation [REDACTED]. Known only by the distinctive eternal flames burning within their skull cavities - a mutation unique even among Pyro specialists. The teal smoke constantly emanating from their form suggests they survived direct exposure to the Great Fire of 2145. Some whisper they were the first to master the forbidden "Soul Burn" technique, though all records of this were mysteriously destroyed. Even their final fate remains unknown, with reported sightings continuing decades after their supposed death.
