Donald Duck

Donald Duck is a Disney character that has made a number of appearances in animation, comics and video games.

In Kingdom Hearts
Donald Duck is the court wizard of Disney Castle, a loyal servant to King Mickey, and one of Sora's two sidekicks throughout the series. Donald is voiced by Tony Anselmo in the English version and Kōichi Yamadera in the Japanese version.

He is a short-tempered, powerful magician on a quest to find King Mickey Mouse.

In Kingdom Hearts, he and Goofy embark on a journey to carry out the missing king’s orders to follow the Keyblade wielder. Donald is one of Sora's two companions who go with him to every world. While he initially only cares about Sora as an asset to track down King Mickey, he eventually grows to deeply care for him as a friend.

At the end of Kingdom Hearts: Chain of Memories, he, Sora, and Goofy are put to sleep for a year while their memories are fixed by Naminé.

In Kingdom Hearts II, he awakens with his friends and continues to fight the Heartless along with the Nobodies and Organization XIII. This version of Donald, like Sora and Goofy, undergoes several transformations on different worlds to blend in with the inhabitants.
