Remy seems calm and composed, but in reality he is a cruel and nihilistic warrior full of wrath and hostility. Though he sees fighting as a futile lifestyle, as it "victimizes people, destroys love, and creates hatred," he continues to fight out of an inability to forgive people like his father, who abandoned him and his now-dead sister to pursue the fight. His resentment is of such a level of vindication that he reports fighters he defeats for the authorities to deal with, and an almost possessive hatred that may be to the point of madness; Remy's pre-battle rival dialogue with Alex indicates that the latter thinks him to be insane and in need of a psychiatrist.
Despite claiming to "hate everything that he sees," Remy obviously still cares for his dead sister, whom he has preserved. He also has an inquisitive, self-doubting side, as he often ponders why his opponents fight, or why he continues to fight despite the fact that he abhors fighting.
