Starting in Japan in 1983, Bandai's Kinkeshi line was licensed in 1985 to Mattel for marketing in the United States and Canada, where wrestling had become popular. This North American line was renamed "M.U.S.C.L.E." (Millions of Unusual Small Creatures Lurking Everywhere!)

They come in random colors, orange, yellow & white, in each character.
