Joker Boss

Description
Joker Boss is a soft floppy jester doll with a hat of three prongs, a wind-up key embedded in his back, and an evil living shadow.

Powers and abilities
Joker Boss's abilities are among the most bizarre of the Bosses, able to summon and control toy-like objects from anywhere for anything, such as enormous toy trains, armies of razor-sharp animate playing cards, bombs in the shape of balloons and rubber balls, and giant living dolls with magical powers of their own. Although Joker Boss can become the size of an adult human, he and everything else shrinks roughly 200 times their original size should they set foot inside a magical toybox he calls home. Joker Boss also owns a large scythe that he can use as a weapon, although his propensity to collapse from physical instability makes physical combat very difficult for him. He relies on a continual winding of his key in order to stay awake, although the key is magical and only requires a slight nudge to start twisting itself.

History
Joker Boss was originally a doll abandoned in his own toybox by a child. The resentment caused him to split between two personalities - a carefree, forgetful, and generally absent-minded but extremely fun-loving character, and a very cruel, sadistic, and malevolent mind which inhabited his shadow. When Magic Box came to recruit him, he joyfully awaited the challenge of the Fighting Polygon, but before long, his evil shadow decided on a whim to take over the world, beginning by draining Joker Boss's physical body of energy and magic, thereby becoming Joker Foe. The Fighting Polygon returned to defeat him, however, and Joker Boss went back to hiding in his toybox and generally having much fun. Eventually his body began to fall apart from neglect, and deteriorated to the point where his mechanisms were no longer capable of supporting him.
