The accomplished hypnotist and occultist, and native of Gotham, Barnabas Cobblepot joined The Victorian Legion under the code name Doctor Mind. He proved to be an asset to the group with his mind reading and persuasion powers. He was able to break open cases or find the mastermind behind any plot just by engaging with bad guys in conversation.

Later he was thrown out of the legion in disgrace after it was found that he was using his powers to coerce young boys to engage in inappropriate sexual activities with him. He was shunned by his family and forced to live the rest of his life in Arkham Asylum to atone for his deviance.
