Sunny

Sunmantha, informally known as Sunny, is a major recurring character in Coupon Kids and a close friend of Pic and Quat. At first glance, she appears to be your typical anthropomorphic dog; however, as revealed by the actress who voiced her in the Coupon Kids anime produced by GAINAX, Sunny is in fact a middle aged human woman wearing a golden retriever fursuit at all times.

She also wants to bone Quat's sister.

Sunny once killed a man in cold blood by running him over with her car for making a flirtatious comment towards her, a crime which she was completely absolved of as the Judge refused to convict her for giving the victim his just desserts.

And she REALLY wants to bone Quat's sister.

Sunny is also known to be trained in 83 forms of hand-to-hand combat, some of which are not even native to the planet Earth, leading many to question where exactly she comes from. When asked about her past, Sunny will frequently decline to comment, and if pressed further, will threaten to "shove my cane so far up your ass it'll come out your mouth" if asked again. She is extremely hardcore and a very good dog.

Plus like she REALLY really wants to bone Quat's sister, you guys. Like, I can't stress this enough. She won't admit it though.

Sunny is dead. This is confirmed multiple times by Tang, who has gone on record as saying "My hottest character is my dead dog." However, Sunny continues to be a regular character in the comics, as she was brought back to life by being prototyped into a kernelsprite in COUPON KIDS X HOMESTUCK: THE KAREZI CHRONICLES.
