“Best imaginary friend ever, eh? He's using a knife for pizza. Sus-*pee*-cious!„~ Bloo Blooregard Q. Kazoo (simply known as Bloo) is Mac's imaginary friend and the main character/antagonist from the Cartoon Network series Foster's Home for Imaginary Friends. He is the only character to appear in every episode. Extremely selfish, rude and arrogant, Bloo has noticeably become much more of an antagonist since the start of the series, serving as an antagonist or otherwise acting downright evil in several episodes. However, there are times when Bloo actually feels remorse for any of his actions and apologizes for whatever he's done.
