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. Due to his arrogant nature, Rugal is an incredibly sore loser. Refusing to accept defeat at the hands of his enemies, he'll instead trigger the self-destruct mechanism of whatever the base he's in with the intention of taking his opponent with him.
