Glegg

Origin
He fell in love with the beautiful, young Peg Amy from Sun Top Mountain; when she persisted in refusing him, Glegg transformed her into a tree. He pursued a complicated strategy over the space of three years to win her, only to be thwarted in the end by Prince Pompadore of Pumperdink and Kabumpo the Elegant Elephant.

Glegg was punished by Ozma of Oz: he was forced to drink one of his own malicious potions, which caused him to explode into nothingness.

The power and versatility of the sorcerer's magic is demonstrated in his creation of Glegg's Box of Mixed Magic.
