He is the field commander of Spearhead Squadron with the codename Undertaker. Having survived 5 years on the front lines, he is considered an elite Processor at the young age of 16. Among the Eighty-Sixers, he is famously known as the Reaper.
His ability to hear the voices of the Legion allows him to locate the Legion without the use of detection systems like radar. The ability developed from a genetic extrasensory ability of the Pyropes that allowed certain people to sense others' thoughts by use of a vestigial region of the human brain.
