Ultimate Muscle was one of several series that 4Kids Entertainment imported to the United States for Fox from Japan. The series made its American debut in 2002, and lasted 2 seasons before Fox pulled the plug. Utaking uploaded the open to YouTube:
As a wrestling fan, I was insulted by the fact that part of Kid Muscle's repertoire required him to fart in the ring. Not funny. We know that they take their wrestling seriously in Japan. Shoot, they take everything seriously. Fox was lucky to find enough marks among the viewers to keep the series around, but it could only go so far.
