This is Hush, AKA Thomas Elliot. He is the childhood best friend of Bruce Wayne, grown up to become one of Batman's greatest enemies. In his civilian identity he is a wealthy neurosurgeon, his devious and manipulative tactics making him an extremely formidable opponent. Elliot attempted to murder his parents at a young age in order to inherit their fortune the way Bruce Wayne did, and blames Thomas Wayne for ruining his life by saving his mother. He seeks to take revenge by ruining Bruce's life on every level.
