Sensei is one of the League of Shadows' most senior members. He is also an associate of the Light, and directs the League of Shadows based on the Light's orders.[2]
Sensei goaded Dr. Serling Roquette to finish her project, otherwise she would pay with her life. Shortly after Red Arrow extricated Roquette from the Island, Sensei was informed by Professor Ojo that the project was done, and Sensei smirked with relish.
While meditating, Sensei was told that Roquette had been tracked down to Happy Harbor, he asked what agents they had in the vicinity.[4]
After the Fog was destroyed, Sensei informed the Light that they had successfully obtained data from STAR Labs, but were unable to get intel from Wayne Tech due to the young heroes' interference. L-2 remarked that they had an operative on the inside, and Sensei exuded satisfaction.[4]
After Ra's al Ghul had died in a battle with Batman, Talia and Sensei oversaw his revival in the Lazarus Pit. It worked, but shortly after Ra's had left, Clayface also rose from the pit. Sensei blamed Talia.[5]
