|Grand Master Wizard|
|Name||Grand Master Wizard|
|Introduced in||"Wizard Battle"|
|Voiced by||Maurice LaMarche|
Grand Master Wizard is first seen in "Wizard Battle." He is in charge of enforcing the rules of and presiding over the Wizard Battle. He is a stickler of the rules and will not allow anything but magic to be used in the Wizard Battle, and anyone who uses only science or weapons cannot participate. If a contestant forfeits or otherwise tries to leave the Wizard Battle, he transforms them into a cat. On that note it should be said that he loves cats and cats can be seen on and around his person at most times. He was too distracted by playing with his cats to notice Ice King using a weapon to cheat.
He has a thick white jacket that could be mistaken as a coat of fur despite the sleeves on it; it covers his whole body. He has yellow skin on his arms at least. He has eyes that resemble cut emeralds, and he wears a thin golden crown with a rod branching up that is set with a single green jewel set at the peak. The top of his head has a different yellow-stained color that doesn't match his white beard and robe, it looks like his head hair but could also be part of his crown.
The Grand Master Wizard erects a semi-transparent sky barrier around the stadium to prevent people from leaving. He also fires a green ray from the top of the emerald in his crown, though it may be that the rays of the setting sun caused it and the crown itself is magical.
- The Snail appears in his jacket sleeve as he's playing with cats.
- He appears to play with the wizards he turned into cats.
- His ability to turn others into cats is somewhat similar to the Thief Wizard's ability to turn himself into a cat.
Ladies and gentlemen, I am the Grand Master Wizard of ceremonies, and now the rules: Contestants will fight each other with spells from the eight schools of magic. No science, Science Whyzard! No weapons, Weapon Head! To enter wizard battle, you must be a wizard!
No! No one is allowed to exit Wizard Battle! The doors are shut, the sky barrier is in place, all of you will kiss the princess or die in battle.
