Wizards have very small upper body and upper arms, which extend out to very broad, three fingered hands. It is wearing a purple coat, which has the heartless emblem on on his chest. Wizards also have a very broad, purple hat, that looks exactly like a witches hat. The wizard's upper body is separated from its lower body by a gold belt. It's legs an feet are hidden due to a bright purple robe beneath its coat. The wizard's head is spherical in shape, and is mostly black. Though you cannot see them, the wizard also has glowing yellow eyes under its hat, similar to almost all other Heartless.
The Wizard also holds a staff called the Wizard's Relic, which it uses to attack.
