Yen Sid

Yen Sid is a powerful sorcerer introduced in Kingdom Hearts II, and originally taken from the "The Sorcerer's Apprentice" short in the Disney film Fantasia. He is a retired Keyblade Master, renowned for his wisdom and command over the arts of magic. Although he is no longer an active Keyblade Master, he still keeps a close watch on the balance between light and darkness. He was once Mickey Mouse's master, and taught him everything he knows of magic and the Keyblade.
