Mac (Foster's Home for Imaginary Friends)

Mac is one of the main characters from the Cartoon Network series Foster's Home For Imaginary Friends. He visits imaginary friends all the time. He was the original owner of Bloo until he had to give him up at the end to stay with Foster's Home, as his mother assumes that's why his older brother Terrence is such a jerk to him because of Bloo. Sean Marquette did his voice.
