Originally a docile inmate at Arkham Asylum, Aaron was an unfortunate victim of fellow Arkhamite Jack Buchinsky's quest to create a perfect henchmen through the use of crude electrical lobotomies. Unlike Buckinsky's other victims, Danzing lobotomy was successful, leaving him open to suggestion and extremely aggressive. Telling his new partner to kill the guards, Danzing and Buchinsky escape Arkham together.
Danzing followed Buckinsky, now being called "the Electrocutioner" by the press because of his electric-based weapons of choice, as Jack attempted to get revenge on the criminals that had turned their backs on him, causing the Electrocutioner to get arrested in the first place.
- Press-releases and IMDb pages of episodes originally suggested Aaron Danzig to be Aaron Helzinger. It was probably so on the early stages of writing and maybe even filming (as surnames "Danzig" and "Helzinger" are very similar and could be dubbed and lip-synced in already filmed sequences with relative ease), but was likely abandoned and changed the last moment, as Aaron Helzinger was largely written into first episodes of Season 2 and Danzig being lobotomized by Jack Buchinsky doesn't really fits original character of Amygdala and newly written Helzinger as well. Pre-operation Danzig, though seems to be accurately based on Helzinger and could be still considered an alternative version of a character.
- As such, the Gotham Season 2 Red Band Trailer shows footage of Aaron Danzig from the episode "Rogues' Gallery" to show Aaron Helzinger's past.
