Donald Duck

Donald Duck is the deuteragonist of the Mickey Mouse franchise.

Despite being a protagonist, he's also an antagonist (more accurately considered as an anti-hero) at times when he bullies and picks on Mickey Mouse, his nephews Huey, Dewey, and Louie, and Chip 'n' Dale.

His first appearance was in The Wise Little Hen (1934), where he was asked by the Wise Hen to help her plant her corn, but he faked a belly ache to get out of doing the chore and play rather than work, along with his friend who did the same thing. When the Wise Hen sees this, she gives them castor oil, to teach them a lesson. As the hen and her chicks eat the corn themselves, Peter and Donald, with nothing but an appetite, repent with all their might by kicking each other on the rear.

He is shown to have rivals, such as Mickey Mouse, Chip 'n' Dale, Gladstone Gander, and many others.

Personality
Donald is very greedy, short-tempered, jealous, stubborn, rude, arrogant, self-centered and selfish who has a very bad temper and very bad luck (two of Donald's main problems), especially when he appears with Mickey Mouse.

He is very egotistical as he believes he deserves the spotlight more than Mickey such as in House of Mouse where he wanted to change the club's name to House of Duck which Mickey protested against.

Donald finds enjoyment in bullying, and has been known to prank and humiliate others for his own amusement. What he can not tolerate, however, is his victims fighting back against him as such, these battles often lead to Donald's humiliation.

His short temper is also his very weakness which has gotten him into tight spots between him and Daisy (who has a more-controlled temper than him) but has lost it on certain occasions.

He is often the target of bad luck which in the theme song about him "Who gets stuck with all the bad luck, No one but Donald Duck!", he is constantly attacked, beaten, and defeated in the end most of the time, but sometimes he comes out on top when he fights back at his enemies and fights to the end.

Despite his negative personality, he is friendly and jovial, and will often team up with Mickey and friends to defeat the villains.
