At one point he came into possession of what appeared to be an alien spacecraft. Recognizing that the vehicle's stealth capabilities made it a lucrative commodity, he began leasing the vessel to various underworld figures, including the League of Assassins. When the vessel in question was linked to an assassination attempt against Connor Hawke, Green Arrow, and Black Canary began investigating its activity. The trail led them to London where they (along with Mia "Speedy" Dearden) engaged in combat with Dodger at a local pub. Although Dodger proved to be an able-bodied physical combatant, "Team Arrow" subdued him and he told them about the League of Assassins.

When pressed for more information, Dodger was unwilling to cooperate, so the Green Arrow and the Black Canary dropped him from the belly of a cargo plane suspended by a bungee cord until he agreed to give them better intelligence. He took them to his secret lair and triangulated the last location of the stealth ship he had leased.

Studying infernal forbidden magic in an attempt to gain the power to challenge his former lover and rob her of the power of Kismet, Tuoni's assault was reflected by Kismet's divine energies and his body was incinerated.

In this new all-powerful form, Dominus escaped the Zone via Superman's Fortress of Solitude and attacked Earth. Attempting to find Kismet to steal her cosmic powers, he was opposed by Superman.

In another battle, Dominus used his reality-warping powers to become Superman, using the Superman robots to search for Kismet while Superman was disguised as one of his own robots and later as Dominus.

The battle ends with Superman banishing Dominus to the Phantom Zone.

Carl Draper is a fictional character in DC Comics, an enemy of Superman.^[104] Draper made his first appearance in Superman #331 (January 1979), written by Martin Pasko and drawn by Curt Swan and Frank Chiaramonte.^[105]

In pre-Crisis comics, Carl "Moosie" Draper grew up in Smallville (see Kator below). Draper was an overweight clumsy teenager whom most of the other kids never noticed or made fun of and was in love with Lana Lang, who had eyes only for Superboy, much to Draper's resentment.^[106] As an adult, Draper underwent a self-imposed self-improvement regimen, including exercise and cosmetic surgery, to overcome his physical shortcomings. He became an expert locksmith and architect, designing an inescapable prison for supervillains called "Mount Olympus". Impressed by the achievement, Superman augmented the prison's security by placing it on an antigravity platform. Initially dubbed "Draper's Island" by Superman, it was informally renamed "Superman Island" by the adult Lana—with whom Draper remained smitten, just as she remained lovestruck by Superman. It was the latter name, plus the novelty of the floating platform, that caught public attention, diverting recognition from Draper himself. This proved the final straw for Draper, who snapped and became the costumed supervillain the Master Jailer.^[107] He attacked Superman and kidnapped Lana under that name. Superman defeated him and he was sent to his own prison.^[108]

In The New Adventures of Superboy #17 (May 1981), at the prodding of Carl, Superboy creates a robot named Kator as a sparring adversary (and gives the "safety cutoff switch" to Jonathan Kent). Kator, however, developed an artificial intelligence and almost killed the Boy of Steel before being destroyed (in The New Adventures of Superboy #18). The robot apparently gave Draper its identity and powers before being destroyed. Draper (as the new Kator) then engages Superboy in combat, but Jonathan Kent presses the safety switch on the "cutoff" device, which removes "Kator's" superpowers from Draper, and Superboy removes the memory of Draper ever being Kator.^[109][110]

In post-Crisis comics, Carl Draper first appeared in The Adventures of Superman #517 (November 1994). This was during the "Dead Again" storyline, when Superman was suspected of being an impostor after his body was found still in his tomb (from The Death of Superman storyline). Draper was hired by S.T.A.R. Labs to design a holding cell for Conduit, when his daughter, Carla, asked him if he could build a prison that could hold even Superman. Draper initially designed a trap that only the real Superman could escape from, explaining this to Superman by way of a hologram of a costumed figure named Deathtrap. When Superman escaped the trap, Draper became obsessed with proving that he could capture the real thing. This version of Draper was dressed in casual wear, only getting an updated costume with chain-based attacks later.

Draper made several other attempts to capture Superman, often programming the Deathtrap hologram in advance so he could publicly be elsewhere. On one occasion, in Superman: The Man of Steel #43 (April 1995), he programmed Deathtrap to appear during a Draper Security press conference and display how Draper's devices were being "subverted", thus both removing suspicion from him and acting as an advertisement for the company.

In Action Comics #739, Superman (in his blue energy form) was captured in an "energy hobble" by Deathtrap, now calling himself the Locksmith. At the end of the story, it was revealed to the reader that his daughter, Carla Draper, was running the hologram this time and that her father was unaware of this. The now-costumed Master Jailer was one of the villains along with Neutron controlled by Manchester Black in the 2002 storyline "Ending Battle"; however, it was not clear that it was, in fact, Draper.

Carl Draper appears in Checkmate #17 (October 2007). At some point, Checkmate discovered his multiple identities and used this to force him into becoming a security consultant, protecting Checkmate itself from attack. In the issue, he prevents numerous assaults on Checkmate headquarters and is promoted to head of security with the title Castellan. Although he has not told his superiors, he strongly suspects that Carla is involved in the attacks. The issue also contains an Easter egg—computer displays show an actual website (now defunct)^[111] that could be accessed with the username "CARL DRAPER" and the password "wilhelmina". The site was a journal and database written from Draper's perspective. In his journal, he claimed to have been only Deathtrap and that he was unconnected with the Post-Crisis Master Jailer.

A DC Rebirth version of the Master Jailer appears in the Aquaman/Suicide Squad crossover "Sinking Atlantis" as a member of the Squad. Aspects of his pre- and Post-Crisis history are present, with Carl growing up in Smallville and having a daughter.^[112]

• The Master Jailer appears as a character summon in Scribblenauts Unmasked: A DC Comics Adventure.^[15]
• The Master Jailer appears in Supergirl, portrayed by Jeff Branson.^[113] This version is an alien from the planet Trombus and a guard at the Kryptonian prison Fort Rozz until the prison ship landed on Earth and many of the inmates escaped. He turned vigilante, hunting down and lynching several escapees until he was thwarted by Kara. Additionally, on Earth, he posed as Detective Draper of the National City Police Department.

Carla Draper is the daughter of Carl Draper who made an appearance in Superboy (vol. 4) #26 (May 1996) under the name Snare. She responded to a request from the Hawaiian Special Crimes Unit to Draper Security for assistance in capturing the supervillain Knockout, who was on the run with a misguided Superboy in tow. Snare, aware of her father's obsession, tried to prove that she could do something that he could not by capturing Superboy. This led to a fight with the SCU, during which Superboy and Knockout escaped.

The Dreadnought is a fictional character in DC Comics appearing in The New 52 continuity. He serves as an agent of the H.I.V.E., along with Psiphon. He appears in Superboy (vol. 4) #20, where he is sent by the H.I.V.E. to New York City to apprehend Doctor Psycho, who had escaped from a H.I.V.E. facility, and Superboy, whose psionic powers were of interest to the H.I.V.E. The two characters teamed up and managed to defeat the H.I.V.E. soldiers. The Dreadnought was sent flying by Superboy and landed in the Hudson River.

Dubbilex is a DNAlien, an artificial, genetically modified human with psychic powers. Created by Jack Kirby, he first appeared in Superman's Pal Jimmy Olsen #136 (March 1971).^[115] In Post-Crisis continuity, he becomes an ally to Superman and was among those who attended his funeral after Doomsday killed him.^[116]

Dubbilex grew close to Superboy, having aided in his creation by providing mental impressions that he had gained from past encounters with Superman to provide Superboy with his '"template"'s memories in the absence of Superman's actual mind. Once Kon-El left the Labs for Hawaii, Dubbilex accompanied him to report his status to Cadmus.^[117] Although their relationship started off somewhat rocky, they became great friends. Superboy taught Dubbilex about many things about the modern world, while Dubbilex represented Superboy during a "parents' night" for the members of Young Justice.^[118]

Dubbilex gained many friends of his own while in Hawaii: Agent Rex Leech, Rex's daughter Roxy, TV reporter Tana Moon, and Bibbo Bibbowski's dog Krypto.^[117] Superboy and most of this group end up operating out of a small, isolated house. Dubbilex also helps uncover the nature of Knockout, While Superboy's super-powered girlfriend has fought villains many times, it is revealed, via Dubbilex's powers, that she casually kills an innocent police officer simply because he was in her way.^[119]

Once Superboy returned to Cadmus, Dubbilex followed and became the Head of Genetics.^[120] Although partly blaming himself for Tana Moon's death, Dubbilex eventually found a retreat and learned from a monk that Superboy needed to move on with life without his guidance.^[121] After Superboy left the Project, Dubbilex has stayed in the background.

Dubbilex and Project Cadmus resurfaced in Countdown to Final Crisis Week 32 (September 2007), in an attempt to help Jimmy Olsen with his new superpowers.

Dubbilex seemingly died due to wounds sustained in battle with Codename: Assassin, when the assassin attempted to eliminate anyone affiliated with the truth about Cadmus' cloning experiments. Despite being shot in the head, his unique physiology allowed him to survive long enough for Jimmy Olsen to find him and learn the truth about recent events. In his apparent last words, he asked Jimmy to consider him a man rather than a creation. Olsen came to believe that Dubbilex was murdered as part of a plot to destroy Superman and all other Kryptonians, such as the recently enlarged citizens of Kandor.^[122] He was later proven right; as "Assassin" is seen working for Lex Luthor and General Sam Lane, avowed enemies of Kryptonians.

Dubbilex (or a new clone of him) still lives and returned to battle Supergirl.^[123]

In 2011, The New 52 rebooted the DC Universe. Dubbilex appears briefly when Kevin Kho / OMAC attacks Cadmus.^[124]
