Quackerjack

Quackerjack is a vicious jester with a weird obsession for toys in the Darkwing Duck series. He was once a toymaker who was run out of business after the "Whiffle Boy" video game market expanded. Understandably, he has a particular hatred of "Whiffle Boy" video games and toys. He became a supervillain who robbed banks to get money to fund his toymaking ventures. However, he's a genius who has built many successful toys. His catchphrase is "It's PLAYTIME!" He also has a doll named Mr. Banana Brain (a parody of Mr. Potato Head), whom he carries around and talks to. Generally, he adapts a high pitched voice to have the puppet talk back in rhyming form.

Most times Quackerjack works alone, but he has been known to team up with Megavolt, and was a member of the Fearsome Five (led by Negaduck and including Bushroot, Liquidator, and Megavolt). His superpower is his "wackiness," which greatly annoys NegaDuck.
