Henry Phage created Mr. Hero as a sleeper agent to send to Earth until such a time as he wished to conquer Earth. He was discovered in the 1800s by a farmer, who later sold him to a magician. The magician trained Mr. Hero to box and used him as a prop in his act. Using Mr. Hero's second head (the "Ratiocinator"), Mr. Hero would give advice to the audience. Then, his less rational but more physically able head would be fitted to his body and he would engage in Queensbury Rules boxing with a member of the audience.
