Starfury the Amethyst Cat

Starfury the Amethyst Cat, also known by her Chinese-translated name, "Xing-Yu Zi Jing-Mao", is one of the main antagonists of SpongeBob & Sagwa 2 alongside Plankton. She is a gemstone cat spirit serving as the empress of Garnet City, the leader of the Amethyst Boars and the proclaimed rival of Yu Bianfu-Wang.

Starfury is voiced by Debi Derryberry, who also provided the voice roles of Jimmy Neutron, Draculaura from Monster High, Clay from 2001-2007 Playhouse Disney, Chica's Magic Rainbow from FNAF World, etc.

Appearance
Starfury appears a tall greyish-purple cat with amethyst gems for spots on her back, green eyes with large single eyelashes and vertical pupils, a swirly tail and a pig symbol on her forehead, which shows that the pig is her Zodiac symbol.

Personality
Starfury is portrayed as the stingy, sadistic and intelligent leader of an army of pig spirits known as Amethyst Boars judging by her Zodiac totem. It is believed that based upon her symbol's yang attribute, meaning "amiability without fidelity leads to immorality", she is known to be remorseless of her actions.

She is also the arch-rival of Yu Bianfu-Wang. Because of this, Starfury has different strategies and decisions from him. Unlike Bianfu-Wang, her sole purpose is to only go around China finding whatever they can steal, which was the main reason behind Plankton awakening her to keep the Noodle Patty formula in SpongeBob & Sagwa 2. She also has more calculating and well-executed plans than Bianfu-Wang as well as better treatment of her minions. Therefore, it is also implied that she is more intelligent than her rival. While Bianfu-Wang tends to be intolerant of failure, Starfury will often accept failure if her plans go to waste, though she still shows no remorse for anything she does.

Trivia

 * Starfury is considered to be one of the greatest villains in the SpongeBob & Sagwa series, due to her superiority over the Jade Bats.
