Gravity Cat is a cat who hates gravity, can fart poison gas, and can do almost anything. He is a minion of Happycat. When he is not amused by someone he kills them by using his epic powers to fly and throw the person. His mortal enemy is Dr. Hax, who threw a computer at the cat for obvious reasons, most famously when the cat killed everyone in the theatre, except for Bo Schitt, his assistant from Half-Life 2, and Dr. Hax.
