Donald is the most aggressive of the group. Though he has mastered spells, Donald is very reckless and is the comic relief in many games. Initially, he and Sora often argued, but in the end grow into a deep friendship. Donald is also very protective over Goofy and King Mickey as he is the most worried in Castle Oblivion when he fears he will forget about Mickey and when he thinks Goofy is dead, he flies into a rage and destroys many Heartless. Despite Donald's short-tempered and impatient nature, he is actually goodhearted, as he would sacrifice anything for the sake of friendship. This is proven twice in the games: when he initially leaves Sora to follow Riku after he obtained the Keyblade, he instead eventually chooses to return to his side; also when the King orders him and Goofy to take Sora from Hollow Bastion to look for Kairi and Riku, he chooses to against his orders to help Leon and the others protect Hollow Bastion. He also seems to be afraid of Daisy as shown at Disney Castle when she yells at him for missing their date.
