Due to a lack of things that he can say, David's personality is somewhat of a mystery. However, him saying "Aw, seriously?" shows us that he can be quite whiny and a person who complains a lot. David is also quite antisocial, often refusing to follow the directions of others and quick to shout his catchphrase whenever greeted with conflict. (He can say only: Aw, Seirously, Wha, and NO)
