O-Sensei src
The O-Sensei is a legendary martial arts instructor.

There is very little known about his origins, except that he used to work with Barney Ling in the organization G.O.O.D.. He took Ben Turner as a student while living in Japan. They discovered a thief named Richard Dragon trying to steal a statue one night. Dragon attempted to kill O-Sensei, but O-Sensei easily defeated him. Despite this violence, O-Sensei saw goodness in Richard Dragon, and decided to teach him as well. O-Sensei spent six years training Dragon and Turner in combat, history, philosophy, and science. Their training eventually finished, and O-Sensei viewed them as sons, but he was forced to let them go pursue their destiny. His students were recruited by Barney Ling, who used them as agents of G.O.O.D..[1] They later left Japan to move to America, and O-Sensei said goodbye with tears in his eyes. Dragon and Turner moved to New York City with O-Sensei's goddaughter Carolyn Woosan.[2] It is later revealed that O-Sensei gave Richard two gifts, both items that had been passed down by his old sensei. This included his own uniform, and a powerful emblem called the Dragon's Claw.[3]
