Balrog is generally self-centered, hot-tempered, arrogant and sadistic. He is a belligerent pugilist who possesses an insatiable urge for money and a vicious, bullying mean streak, often refusing to take responsibility for his actions. Despite being a once great prize boxer, Balrog intentionally cheated in his fights whenever he felt like it, and has even killed one of his opponents (though by accident). The only depiction of empathy and humanity in him is his relationship with Ed, showing that deep down, he is capable of proper relationships, empathy and even fellowship. Even after their fight and the latter leaving, he is shown to genuinely care about Ed.
