Unlike Matt Murdock, Stick was born blind, so he has trained his techniques to a very dangerous style enabling him to protect himself better than a seeing person could. Stick is the master of the Chaste, a group of mystical ninja which seek spiritual purity and enlightenment as well as physical toughness. They have feuded with their rival group, The Hand, for centuries in a legendary secret war that stretches back to feudal Japan.
Stick has made it his mission to keep the Chaste pure and clean from any evil infection. He forbade another of his prominent students, Elektra Natchios, from staying between their lines because of her vengeful personality, in spite of her formidable progress.
Stick is quite punishing and arrogant with his charges. He encountered the X-Man Wolverine when he was in his feral state and brought him back to reasoning, in part because of continued battering from his bo (staff) and hard nose advising.
Eventually, the Hand sought to wipe out Stick and the good warriors of the Chaste altogether. Stick thwarted an assassination attempt by four Hand operatives; he then summoned the other members of his order to New York City. With the assistance of his clan, Stick defeated Kirigi, the Hand's most lethal ninja at the time. The Hand regrouped and attacked Stick and his band of warriors that now included Daredevil and his then current lover, Black Widow. The Hand had almost overpowered the small band of warriors, when Stick and Shaft resorted to an ancient technique that drained the life force from all ninja present. Unfortunately, the technique resulted in the explosion of Stick and his comrade as a result of the excess energy they had absorbed. The Hand considered the destruction of their arch-nemesis and leader of their enemy a victory and turned their attention to other schemes.
Years later, the Hand again turned its attention to the leaderless Chaste, once again attempting to destroy them, this time to prevent the Chaste's members from locating the new-born child that would bear Stick's reincarnated soul. The Hand severely crippled Stick's soldiers, reducing their number to a handful of warriors. The few remaining traveled to New York, seeking the assistance of Daredevil. Reluctantly, the Man Without Fear aided his former mentor's disciples, returning with them to Japan. Once there, The Hand attacked the Chaste and Daredevil relentlessly. Fighting alongside Daredevil, the Chaste barely managed to escape and safeguard their master's reincarnated spirit.
Stick is a reference to the Zen master Nantembo (1839-1925) - who was famous for striking his students with his nantin staff.
