Jonathan Crane

Jonathan Crane is a psychology professor obsessed with fear. Due to a harsh childhood in which he was intimidated by his physicality and his passion for studies, Crane develops a kind of obsession with taking revenge through fear.

This trauma was never overcome and his withdrawn personality mutated into an unscrupulous soul.

He becomes more and more obsessed with the concept of fear and causing fear in others, since it gives him the power and control that he never felt during his childhood.

Jonathan is often described as cunning, cocky, cruel, and intimidating. He constantly filled the people around him with feelings of unease and discomfort due to his creepy obsession with fear. Jonathan is quiet, calculated, observant, and unpredictable.

He was incredibly intelligent, calm, sly, intuitive, seductive, perverted, lustful, bold, and blunt. To many people, he may be seen as domineering, patronizing, and condescending due to his passive-aggressive, intense nature.

Jonathan was very dominant, aggressive, rough, and sinister, giving him an eerie aura. He was a genius, perceptive, handsome, dirty-minded, psychology professor. Most people, including his colleagues and students, thought of him as creepy, obsessive, possessive, and petty.

At times, he could be flirtatious and seductive. Though, he was mostly sadistic, manipulative, selfish, egotistical, and narcissistic.

As a young child, Jonathan Crane was subjected to sick and twisted experiments on fear conducted by his own father. Emotionally scarred and mentally unstable from the ordeal, Crane spent his childhood living in fear until he made an important realization—if he could control fear, it would never again control him.

Abused and bullied in his youth, he develops an obsession with fear and uses a specially designed hallucinogenic drug–dubbed "fear toxin"–to exploit the phobias of the people of Gotham City and its protector, Batman.

As the self-proclaimed "Master of Fear", the Scarecrow's crimes do not stem from a common desire for wealth or power, but from a cruel pleasure in terrorizing others to further his sadistic experiments on the manipulation of fear

Crane, in almost all of his incarnations, is cruel, sadistic, deranged, and manipulative above all else. Crane is obsessed with fear, and takes sadistic pleasure in frightening his victims, often literally to death, with his fear toxin.
