The Crane Serum is a powerful hallucinogenic compound which was created by the late Gerald Crane, and is utilized by various criminals in Gotham City (most notably by Gerald's son, Jonathan).

History

After being paralyzed with terror during the burning of his house (which led to the death of his wife), Dr. Gerald Crane became obsessed with overcoming fear, and thus, began harvesting the adrenal glands (most notably, cortizal and adrenaline) of people in high-intensity fear situations (killing them with their own phobias, in order to maximize their state of terror at the moment of death) to create this serum which forces the subject to see their greatest fears, in the hope that seeing said fears would allow them to face and overcome said fears.[1]

Upon completion, Crane took the serum himself, and became completely fearless as a result of overcoming his fear, ultimately resulting in his death when he initiated a shootout between himself, Harvey Bullock and James Gordon. As shown with Crane's son, Jonathan, a high enough dosage of the serum could force the subject to see their fear constantly.[2]

Hugo Strange took to employing the serum in his procedures at Indian Hill, such as using it on Oswald Cobblepot in order to rehabilitate him and change his personality.[3]

The serum is later recreated when Grady Harris and Merton's team forced Jonathan Crane into making a new batch for them to use for crimes. Crane updated the serum's formula and made it into a gaseous version. Jonathan eventually uses the formula himself, upon donning the moniker 'The Scarecrow'.[4] Upon entering Gotham Asylum, Scarecrow gassed Warden Reed and the inmates of Arkham Asylum.[5]

Capabilities

Upon exposure, either through injection or inhalation, the Crane Serum causes its victims to experience hallucinations of either their deepest fears, or their own inner demons (as shown with Gerald). Eventually the effects will wear off and the victim will revert back to normal (albeit with some differences, as Gerald became completely fearless following his inoculation)

Adverse effects

Anyone who is exposed to larger-than-average doses of the serum will still see their greatest fear/inner demons through hallucinations, but twisted into a much darker, more demonic form. Prolonged exposure can induce minute brain damage, placing the victim in a constant state of intense terror. Victims such as Jonathan Crane and Warden Reed, who were exposed for an extended period of time, become what they fear. As shown with Gordon though, people with strong enough willpower can resist the effects, a feat which Jonathan claimed to be impossible to the point that "[one] can't simply stop being afraid, [one] can only become [their] demon".

Trivia

  • The Crane serum is based off the fear gas that Scarecrow uses in the comics.
    • Interestingly, this version of the Scarecrow's Fear Toxin bears similarities to the "Super Toxin 451-A" from Batman: the Dark Knight (Volume 2).
  • Curiously, Reed was exposed to this serum for a far shorter period of time (in comparison to Jonathan, who suffered under its influence for three years) before becoming one with his fear.
