First comic appearance: Detective Comics #74 (April 1943)
Arkham Asylum appearance: Arkham North (Entrance Gate)
The connection: Two more characters who steal their persona from nursery rhymes and Lewis Carroll books… what are the odds? Pretty high in Gotham City, we suspect. While the pair are not considered particularly insane, they do appear in the aforementioned Arkham Asylum: A Serious House on Serious Earth. In that graphic novel, they are connected by a couple of electroshock helmets, with one as the left half of the brain and the other as the right half.
So are the beanies sitting on this seesaw equally complicated? Or are they simple, silly costume hats? We may never find out.
Bizarro Fun Fact: In the comics, the original Tweedledum has died and been replaced by his twin brother. Both are cousins to Tweedledee.
First comic appearance: Batman #386 (August 1985)
Arkham Asylum appearance: Arkham Mansion (Dr. Young’s Office); Medical Facility (Patient Observation)
The connection: Roman Sionis’s parents were obsessed with appearances. They covered up the fact that Roman was dropped on his head as a baby because they feared the social repercussions. They hated Bruce Wayne’s parents, but remained friends with them because it looked good to do so. Because his family always wore metaphorical “masks” in public, Roman chose that theme when he was driven to become a villain. His trademark mask, found in Dr. Young’s office, is carved from the coffin of his dead mother… who he murdered, along with his father. Yuck.
There’s another reference to Black Mask in the newspaper clippings that mention Firefly and the Injustice Gang. “Roman Sionis in court!” screams the headline. This probably refers to the incident in which his cosmetics company rushed a product to shelves and ended up disfiguring hundreds of women.
Bizarro Fun Fact: Black Mask was killed by Catwoman. Not once, but twice.
First comic appearance: Batman #609 (January 2003)
Arkham Asylum appearance: Medical Facility (Surgery Room)
The connection: Hush’s true identity is Tommy Elliot, a childhood friend of Bruce Wayne’s. Like Bruce, he had a wealthy upbringing and traveled the world after his parents’ untimely death. Unlike Bruce, he was the one who killed his parents. When he returns to Gotham City, he works as a famously skilled surgeon before letting an irrational jealousy and hatred of Bruce consume him.
Based on this white board, Tommy Elliot has not yet been revealed as Hush in the Arkham Asylum universe. The alter ego may not even exist yet… but could emerge for a sequel.
Bizarro Fun Fact: As an adult doctor, Thomas Elliot treated a patient named Edward Nigma (aka the Riddler). As a boy patient, Thomas Elliot was treated by Dr. Jonathan Crane (aka the Scarecrow).
First comic appearance: Batman #63 (March 1951)
Arkham Asylum appearance: Botanical Gardens (Aviary)
The connection: Would you be surprised if we told you that a low-rent villain called Killer Moth carried a cocoon gun? Of course not. Based on the morbid scene above, however, Arkham Asylum might be going for a darker take on the character. The cocoon gun is supposed to trap victims only – there shouldn’t be a skeleton unless he left his prey to starve up there.
So he’s either seriously sadistic… or he’s Charaxes, a monster that Killer Moth transformed into upon selling his soul to a demon. Yes, this actually happened in a 1995-1996 miniseries. Charaxes secretes an acid that can dissolve human flesh.
Bizarro Fun Fact: Killer Moth really envies Batman’s style. He built himself a Mothcave, drives a Mothmobile and occasionally uses a Moth-signal.
First comic appearance: Detective Comics #259 (September 1958)
Arkham Asylum appearance: Penitentiary (Main Cell Block)
The connection: Batman villains love their themes, but this guy is ridiculous. His alter ego is Julian Gregory Day, a three-word name that manages to cram in three references to calendars. If you haven’t guessed his modus operandi yet, you’re not even trying. He plans crimes so that they relate to the day on which they are committed. In his Arkham Asylum cell, you can find torn pages for January 1st (New Year’s Day), July 4th (U.S. Independence Day) and November 19th (possibly Thanksgiving). What do the other dates signify?
Bizarro Fun Fact: Calendar Man is often considered a pathetic joke enemy, easily dispatched by the Teen Titans or Power Girl. In the story for Batman: The Long Halloween, however, he is cast as a creepy and clever Hannibal Lecter-like character.
First comic appearance: New Year's Evil: Prometheus #1 (February 1998)
Arkham Asylum appearance: Penitentiary (Guard Room)
The connection: Prometheus is often described as the anti-Batman. Because he witnessed his criminal parents get gunned down by police while a child, he has committed himself to hunting down and destroying law enforcement. Prometheus is the ultimate “cop killer” and, therefore, one of the GCPD’s most wanted felons.
Bizarro Fun Fact: For awhile, the mantle of Prometheus was held by the son of a cop, who murdered his parents because they wouldn’t let him play videogames. Sigh.
First comic appearance: Detective Comics #483 (May 1979)
Arkham Asylum appearance: Intensive Treatment (Patient Pacification Chamber)
The connection: Maximillian Zeus, like so many Batman foes, takes his name far too literally. He has a god complex, honestly believing that he is Zeus, the Greek god of thunder, sky and lightning. This explains the symbols and mythology book found in his Arkham Asylum cell, which is hidden behind a wall in the Patient Pacification Chamber.
That location is significant as well. In the graphic novel, Arkham Asylum: A Serious House on Serious Earth – the same story referenced for the Mad Hatter and Tweedle entries – Maxie Zeus is addicted to electroshock therapy, calling the currents “fire from heaven”.
And thus, the indignant clue from the Riddler: “Even I was shocked when I saw how Maxie Zeus was treated!”
Bizarro Fun Fact: In the same disturbing comic story mentioned above, Maximillian is implied to be a coprophiliac, meaning that he derives pleasure from feces. Come to think of it, his cell does look a bit dirty…
