The Butt-Ugly Martians (B.U.M.) are forced to invade planets for the evil Emperor Bog. When they are sent to Earth they become addicted to American culture, deciding not to hurt the earth and simply pretend to be occupying the planet for Bog. They are shown around by their new Earthling friends: Mike, Cedric, and Angela. The Butt-Ugly Martians will continue to hang out on Earth as long as Emperor Bog never finds out. The franchise also had a toy line by Hasbro.
