Rugal is a cruel and powerful man who will kill anyone who stands in his way. He sees absolutely no value in human life, to the point where he proudly displays the metal-encased corpses of worthy opponents he has killed in battle as trophies. He will even go so far as to kill people simply to spite others (such as when he slaughtered Heidern's family simply because he found Heidern to be a disappointment). Unlike most other KOF villains, Rugal has a sadistic sense of humor about what he does. Many of his winquotes are snarky insults toward his opponents, and he often sees the act of taking human life to be more of a pastime. Most of his powers are from his physical strength and his ability to imitate other attacks. Since gaining Orochi power, he has expanded his abilities to lethal heights. However, he can only use a fraction of the Orochi power, lest he is consumed and destroyed by it, as it happened in 95. Upon his revival, he continues using his powers that are from the borrowed Orochi blood, but he is still just as susceptible, despite his growing mastery of his own powers.
