Amygdala is the alias of DC Comics character Aaron Helzinger, who is a sometime opponent of Batman. He has reduced mental capacity, near superhuman strength and endurance, and is prone to outbursts of violence due to medical experimentation on his brain, chiefly the removal of his amygdala.

Publication history[edit]

Amygdala first appeared in Batman: Shadow of the Bat #3 and was created by Alan Grant and Norm Breyfogle.

Fictional character biography[edit]

Anatomically, the amygdala refers to the bundle of nerve cells in the brain that control emotional associations of many kinds. Aaron Helzinger's amygdala cluster was removed in an attempt to cure him of his homicidal rage. This procedure resulted in Amygdala becoming exceedingly angry and was the opposite of what the surgery was intended to achieve. Easily led due to his childlike nature, Amygdala has been the pawn of a number of Batman villains, but when properly medicated, he can be peaceful.

Amygdala first appeared in Shadow of the Bat #3 in 1992 during the story arc Batman: The Last Arkham. In the issue, Amygdala was forced to attack Batman by the maddened Jeremiah Arkham. Batman subdued Amygdala, but was then forced to face more inmates.[1]

Amygdala later appeared in Part 2 of the year-long story arc Batman: Knightfall, which also saw other characters introduced in Batman: The Last Arkham return to the comic book universe, most notably Zsasz and Jeremiah Arkham. In Knightfall, Amygdala was freed from Arkham Asylum by Bane along with numerous other inmates and was soon under the control of the Ventriloquist. Batman intercepted Ventriloquist, but was promptly attacked by Amygdala. As Ventriloquist escaped, Batman subdued Amygdala once more and the villain did not appear again in Knightfall.[2]

He has been released into the community on numerous occasions, where he has been an ally and friend of Dick Grayson (Nightwing, the former Robin). He lived in the hero's apartment building and worked as a warden in Lockhaven Prison. When Blockbuster was in the process of breaking Nightwing down both physically and emotionally, Blockbuster destroyed Grayson's apartment complex while Amygdala was inside. Amygdala survived, but he was heavily traumatized by the death of his friends.

In the Infinite Crisis storyline, Amygdala was among the villains that joined Alexander Luthor, Jr.'s Secret Society of Super Villains.

He also appeared in the 2008 mini-series Gotham Underground, drinking in the Penguin's Iceberg Lounge.

In the DC Rebirth reboot universe, Amygdala appears as one of the many villains attempting to kill Batman to stop Two-Face from leaking secret information. Alongside Killer Croc and King Shark, Amygdala attacks Batman on a train.[3]

Powers and abilities[edit]

Amygdala is a huge man with the strength and endurance of a championship bodybuilder. His emotional instability and explosive rage enhance this even further, making him prone to bouts of boundless violence unrestrained by the usual barriers and limits set in place by one's self-awareness.

Other versions[edit]

In the Elseworlds tale Batman: Crimson Mist—the third part of the trilogy that began with Batman & Dracula: Red Rain, in which Batman becomes a vampire—Amygdala makes a cameo during Batman's assault on Arkham Asylum. Amygdala is killed and then beheaded by the vampire Batman.

In science[edit]

Amygdala is briefly referenced in an article by Joseph LeDoux,[4] a neuroscientist and expert in the role of the anatomical amygdala in fear processing, as testament to popular interest in the brain area.

In other media[edit]

Stink Fisher portrays Amygdala in the television series Gotham.[5]
