Character from Foster's Home For Imaginary Friends, Mac (voiced by Sean Marquette) is Bloo's creator (having imagined him at the age of three) and Terrence's younger brother, a short boy with brown hair. He is a bright, shy, and creative eight-year-old who visits Foster's every day. He wears a red shirt with white, spotted sleeves, olive pants, black shoes, and carries a backpack. Mac is often the voice of reason among his friends when they are making decisions. He has the patience to endure Bloo's quirks as well as the eccentricities of other characters. However, his extremely good nature tends to make him somewhat naive. He is very attached to Bloo, and it is shown that his biggest fear is never seeing him again. Mac lives with his mother and his older brother, Terrence, who regularly bullies him.
