Iron Master was formerly known as Legless Master when he and his brother, Armless Master fought together in the Thai fighting circuit. His signature move was an attack called the Whispering Hand, a powerful single blow technique. When Tim Drake went to paris to complete his martial arts training, he sought out Iron Master's dojo. There Tim met Dava who wished to learn the whispering hand technique. Iron master was killed by Lady Shiva when he refused to tell her Dava's name.
