As the leader of his brothers, he greatly respects the sense of honor, justice and responsibility, as well as the physical abilities and wisdom that someone may have, especially if they are part of the good side. If he perceives a threat, he will not stop until he eradicates it or proves otherwise, always seeking to know the why of something (whether it is why someone is a villain or in finding their motivation to act that way) trying to dialogue if possible with the person he fights with depending on whether they are open to dialogue.
He tends to be more emotionally closed, but that doesn't mean he can't develop feelings.
He takes missions quite seriously as he is the leader among his brothers, able to recognize how capable a person can be.
