Canadianman is a large and very powerful Choujin from Canada. He usually lives as a lumberjack, but also owns his own gym called Canadianman Gym. His body is colored like the Canadian Flag and he has the Maple Leaf on his chest. He is exceptionally strong, being able to lift the Korakuen Stadium during his fight with Robin Mask during the Choujin Olympics. He was initially depicted as a top-label Choujin, but afterwards became less active and, along with Specialman, became one of the most well-known "background" Choujin in the story.
He appears in Kinnikuman Nisei as a Legend and the father of Canadian Boy. He recently appeared again during the Ultimate Choujin Tag Arc. He and Specialman are reluctant to be picked to take part in the Reserve Match. It is also revealed at this time that after Canadianman was eliminated from the Universal Choujin Tag Tournament, he returned home to find that his gym had been trashed.
