Willie the Giant

Willie the Giant is the main antagonist of the Mickey and the Beanstalk segment of Fun and Fancy Free, and later, one of the main protagonists from his other appearances. He was voiced by Billy Gilbert in the original film and has since been voiced by Will Ryan and Jeff Bennett.

Personality
Willie is incredibly powerful, demonstrating amazing magic powers such as flight, invisibility, and metamorphosis. Despite this, he is very childish and not considered very bright, given his fondness for toys and inability to pronounce certain words, such as pistachio. His favorite food is implied to be chocolate pot roast with pistachio, given his overweight appearance. But he can also be very greedy and uncaring such as when he stole the golden harp from Happy Valley and did not care that the land and the people were suffering. However, after the events of the film, he seems to have become more polite and humble, this is most noticeable in his later appearances.

Mickey's Christmas Carol
In the film, he is protrayed as the Ghost of Christmas Present. In this depiction, although still bumbling and lacking in intelligence, he is good. He shows Uncle Scrooge the meaning of generosity and warns that there may be trouble ahead for the Cratchit family, and ultimately Scrooge himself.

Who Framed Roger Rabbit
Willie can be spotted as a poster in a movie theater in Toontown.

Disney Parks
Willie makes an appearance in the Sir Mickey shop at Magic Kingdom and Disneyland Paris, lifting part of the roof and peeking inside.

Powers & Abilities
Despite his childish mind, Willie is a surprisingly powerful user of magic, claming all he needs to do is chant a spell Fee-Fi-Fo-Fum, and he can perform shapeshifting, fly, and become invisible.

But even aside from his magical powers, Willie is a powerful physical force, oweing to his size and strength.

Still, Willie is not invincible - He has his weaknesses, one of which is implied that he is subject to the limitations of the forms he takes, such as when Mickey had planned to swat him when he'd tried to get Willie to turn himself into a fly. And of course Willie isn't all that smart but he is able to realize when he's been tricked, or almost tricked.
