He is very smart and strategic, but also very cocky. He believes in and cares greatly for his friends. He is very blunt with words. He is also very aware of what goes on around him and has a strong connection to the spiritual. Aside from his strong cockiness, he is always serious and ready for anything. Sometimes, he can be a tad bit sarcastic.

The characteristic that stands out most about him is that he explains things in large, full detail.
