The Armless Master, a man with no arms but using only his legs is still a magnificent fighting force. He trained two of DC Comics' martial artists. One whose very name is whispered in Gotham as the world's greatest thief: Catwoman. Second one is a B-list villain and mercenary who was the greatest student to walk out of the Armless master's class and brought Catwoman to his dojo: Hellhound.
Many years after this, one of the deadliest assassin in the DC Universe, Lady Shiva, attacked and killed the Armless Master, then blamed Bruce Wayne (Batman) for this death, while he was still recovering from Bane's attack. The result was Bruce being attacked by a numerous amount of the Master's students.
