Luffy - funny,stupid Ace - angry and smart Sabo - smart and calm Garp raised his grandson Luffy and holds high standards for him,[13] and gets mad at the slightest mistake he makes, even when his own are sometimes no better (i.e., telling off Luffy for falling asleep only to fall asleep himself). This often leads Luffy to receiving the force of Garp's punches, and due to these experiences, he has become afraid of his grandfather.
