This is an image of Donald Duck,one of the main protagonists in the Kingdom Hearts series.Donald,in Disney canon, is a sailor with a dangerously short temper. His debut is in The Wise Little Hen. In Kingdom Hearts, Donald is the Royal Magician of Disney Castle and the royal assistant for King Mickey. As such, his weapon of choice is a Staff. He often provides comic relief more than advancing the plot despite the amount of camera time he has in the series. He is rash and has an aggressive personality, but he is loyal to his friends. 

Though he initially only cares about Sora as a means to track down King Mickey, Donald soon grows to deeply care for him as a friend.

"Confounded Heartless! Get lost, will ya?"
