A very fucking serious white cat popularized by imdb.com user Timmys_DownTheBloodyWell. He is Emperor and Supreme overlord of a board called "The Sandbox" as well as President of the Anti-squirrel coalition. In his spare time he enjoys spreading awareness of the seriousness of a thread, killing infidels (mostly squirrels), and he also taking long llama rides on the beach.
