In 2011, Sanrio (the creators of Hello Kitty) acquired the licensing rights to the Mr Men and Little Miss characters from Chorion. Costumes With Character produce her exclusively for the license holders Sanrio. Mr Strong is a square, red, inanimate, antron fleece-covered character with a green hat. He carries two black dumbbells. He has a friendly, smiling face. Sometimes Mr Strong in the Mr Men show is a triangular character, but he is square in the books.
