From Homestar Runner Wiki
At knee-height (1' 2"
et 18lb.), covered with yellow fuzz, and sporting a gold tooth,
The Cheat is decidedly "holy crap adorable". He speaks entirely in a language of high-pitched squeaks and growls, which is actually called "The Cheat", and other characters apparently understand it just fine. The Cheat is loyal to
Strong Bad, protected by
Strong Mad, and respected by the rest of the gang. He is an amateur Flash animator in his spare time, creating
Powered by The Cheat cartoons and music videos. The
Cheat Commandos are based on
Firebert, The Cheat's alternate persona (with a bad commando name).
