Yu Bianfu-Wang

"I am the great, powerful and utterly malicious King Jade Bat, and I'm ready to destroy China! Bwa ha ha ha ha ha!"

- Bianfu-Wang Yu Bianfu-Wang, also known by his English-translated name King Jade Bat, is the main antagonist of SpongeBob & Sagwa (the video game) as well as the first season and first half of season two of the TV series. He is the original archenemy of the titular characters, the leader of the Jade Bats and the arch-rival of the future series antagonist, Starfury the Amethyst Cat.

Bianfu-Wang is voiced by Jim Cummings, who also voiced various Disney characters including Tigger, Peg Leg Pete and Darkwing Duck, as well as Cat from CatDog, Taz from the Looney Tunes franchise and Dr. Robotnik from Sonic the Hedgehog (SatAM).

Appearance
Bianfu-Wang is a gigantic, muscular, green bat spirit with long hair extending down to his neck to make a beard combo, bushy eyebrows, long lower fangs, huge claws, a long tail and giant bat wings.

Personality
In the first video game and the very first episode of the show, Bianfu-Wang was a very intimidating, menacing, powerful and sadistic monster who did whatever it took to achieve his evil goals. He would imprison anyone who dared to reawaken him from his eternal slumber, like he did so with Patrick. He was also a very feared entity to many Chinese residents, so he is also a fear monger.

However, since the episode SpongeBob and the Catfish, viewers began to notice that Bianfu-Wang was losing his cunning nature and was transforming into more of an incompetent comic relief antagonist rather than a stereotypical dark overlord antagonist.
