The story revolves around a young boy named Sport Billy who is from the planet Olympus (a twin of Earth on the opposite side of the Sun) which is populated by athletic god-like beings. Billy himself has a magic size-changing gym bag - the Omni-Sack - which produces various tools as he needs them. Billy battles the evil Queen Vanda and her gnome-like henchman, Sipe. Vanda's mission is to destroy all sports in the galaxy since fairness disgusts her. (Wikipedia)
