The Jester (oz)

The Jester was planning to destroy Dorothy to get rid of her once and for all

When the Jester was just a young boy, he often tried to steal his sister's broom for himself. Not only that, but she also did terrible, repugnant, and abominable stuff to him. At some point, she placed a spell on him that prevents him from taking off the same outfit. Whenever he attempted to take it off, another one with different colors would appear each time. Even after her death, the spell remained intact.
