Jonathan Crane

Jonathan Crane is the son of the late Gerald Crane.

Early life
He lived with both parents in a house outside of Gotham. His mother died in a fire when he was eight years old.

Assisting his father
Jonathan Crane helped his father murder people by killing them with their worst fears, although he does have some reservations and second thoughts over his father's actions. When Gerald is in the process of drowning a bound and gagged Scottie Mullen at a swimming pool (due to drowning being her worst fear) Gerald orders his son to return to the van and feed the parking meter. But Gerald's plan to kill Scottie fails as detectives Jim Gordon and Harvey Bullock arrive on the scene and save her, although Gerald manages to escape in the van with Jonathan.

Using the adrenal glands taken from his victims, Gerald created a serum which he hopes will remove all fear. He uses it on himself in order to face up to the death of his wife, having felt failure over allowing her to die due to his fear. When the process works Gerald plans to use it on Jonathan to eliminate his fear. The terrified young man flees their home and showing reluctance at his father's beliefs says he isn't afraid. Gerald manages to convince Jonathan to return home, and injects him with the serum. Later that evening Gordon and Bullock track them down. Out in a field, Jonathan (who is overdosed on the serum) looks up at a Scarecrow and with bad side effects starts screaming in terror. At the scene Gerald ends up being killed when (due to not having fear) he opens fire on the two detectives, which leads to him being shot dead. Jonathan is taken to hospital, where the doctor reveals to Gordon he is having very odd brain activity. When Gordon asks whether or not he will make a full recovery, the doctor says he won't and will be forced to witness his worst fear every moment of his life. Gordon watches a terrified Jonathan, who strapped to a bed is under a great deal of stress as he hallucinates a monstrous scarecrow sneaking around his bed, and eventually 'attacking' him.
