The Master, Yen Sid

Name: Yen Sid
Nickname: Master Yen Sid
Alias: Master Yen Sid
Personality: While little is known about his life as a Keyblade master, the elderly sorcerer is shown to be a rather stern man. In almost every instance, he is shown to be frowning. But beneath his harsh exterior belies a man who strongly believes in his apprentices no matter how much mischief they may get up to, demonstrated by when he expresses annoyance at Mickey for running off with the Star Shard and recklessly getting lost with it, but then forgives Mickey and awards him the title of Master with an encouraging smile.
Origin: The great sorcerer first appeared in the Fantasia short The Sorcerer's Apprentice as Mickey Mouse's master. He was the owner of a magical hat (which he wears in Kingdom Hearts II) that is apparently a major source of his power. As the last remaining Keyblade Master, his sole purpose at the academy is to train one more person to take the title, and then go back to his tower so the new Master can train others.


He disciplined Mickey in The Sorcerer's Apprentice, (1940)
