Ultimate Muscle is the story of Muscle mans (Kinnikumans) son Kid muscle.

It is going to start airing on The fox Box(formally fox kids) on Saturday mornings at 9:30 and 10:30. The fox box is airing 2 shows in a row now. From 9:30 to 10:30 in the morning you get your weekly dose of muscle wrestling action.

Toys 'r' us ran a special where you could get a free Fox Box with information on the new shows that will be airing. It included a CD with information on the shows as well as a short movie with the intro.
