Robby is a kind-hearted man, and always sees the pure in others, other than Miguel Diaz or his father, Johnny Lawrence. He is like an overprotective big brother, always looking out for his lover with their best interest at heart. However, he has slight anger issues. If he's angry, he won't hide it. You can see it from a mile away if he's upset about something. His mood can differ from time to time, but he remains a pure-hearted man. He's forgiving, except to his father.
