Personality and traitsEdit
- Six: "Be careful Rex, he doesn't look as strong as you."
- Rex Salazar: "You're underestimating him, he's as wild as the sea, you'll learn that after awhile of spending time with him."
- Six: "...I think I'll pass."
- ―Agent Six and Rex, talking about Nathan.
Nathan is brave, a natural leader, and is willing to risk his life to save friends, strangers, and sometimes enemies. He has a sarcastic and smart sense of humor, a laid back demeanor, and has earned in a short time the respect of all the major characters in the series, even Black Knight (who strictly dislikes most men), White Knight (who hates most E.V.Os), and Six (who generally doesn't socialize with people). He also earned the trust, and respect of the Pack (who don't usually trust allies of Providence). Despite this, Nathan remains true, and usually never goes back on his word.
However, he is definitely not perfect. Nathan is somewhat short-tempered, and thus has trouble controlling his anger (when he sees bullying) and tends to do or blurt out things before thinking, no matter the consequences, causing him to get in a lot of trouble. Nathan can also be sarcastic and moody, and he dislikes being restrained or forced to obey. After living on the streets, with and without Rex, Nathan has developed a "wolf stare" that says "No matter how bad you think you are, I'm worse".
Nathan's fatal flaw is revealed to be excessive personal loyalty, to his loved one and those who are rated highest in his heart, at one point he was told that "to save a loved one, he would sacrifice the world".
