Once in time, Schiller became Batman's teacher and a psychology professor at Gotham University. On his first day here, Bruce Wayne entered the psychological clinic. Schiller had no choice but to open the American comic chat system and make his first post. : Batman asked me about the meaning of life, how should I answer? I’m waiting online in a hurry. Thanos: I suggest you kill him directly. Professor Driggs is a world-class master of criminal psychology and the most famous psychology professor at Gotham University. His students include both superheroes and super criminals, but he does not belong to any of them. Batman likes to call him professor. The Joker calls him the calmest lunatic, the Scarecrow calls him the one who slipped through the Arkham net, and Nick Fury thinks he's the one who got away with it. He's Batman's teacher.
