Amadeus Arkham is a character in DC Comics. He was the founder of Arkham Asylum and is the uncle of Jeremiah Arkham.^[77]

He was created in 1984 for the entry for Arkham Asylum in Who's Who: The Definitive Directory of the DC Universe #1. The story was retold and expanded in 1989 in Arkham Asylum: A Serious House on Serious Earth. The graphic novel is interspersed with flashbacks to Arkham founder Amadeus Arkham's life and childhood. The character appeared in DC's The New 52 as a protagonist of All Star Western alongside Jonah Hex.

The Who's Who entry establishes that the Asylum was named after Elizabeth Arkham, the mother of founder Amadeus Arkham. The original name of the asylum was Arkham Hospital. Its dark history began in the early 1900s when Arkham's mother, having suffered from mental illness most of her life, committed suicide (it was later revealed that her son actually euthanized her and repressed the memory). Amadeus Arkham decided, then, as the sole heir to the Arkham estate, to remodel his family home and properly treat the mentally ill. Prior to the period of the hospital's remodeling, Arkham treated patients at the State Psychiatric Hospital in Metropolis, where he, his wife Constance and daughter Harriet had been living for quite some time.

Upon telling his family of his plans, they moved back to his family home to oversee the remodeling. While there, Arkham received a call from the police notifying him that serial killer Martin "Mad Dog" Hawkins — referred to Arkham by Metropolis Penitentiary while at State Psychiatric Hospital — had escaped from prison, and sought his considered opinion on the murderer's state of mind. Shortly afterward, Arkham returned to his home to find his front door wide open. Inside, he discovered the mutilated bodies of his wife and daughter in an upstairs room with Hawkins' nickname carved on Harriet's body.

The shock of the murders brings back the memory of killing his mother. For many years, Elizabeth suffered delusions that she was being tormented by a supernatural creature and would call to her son to protect her. One day, however, he finally sees what his mother saw – a great bat, a spectre of death. Taking a pearl-handled straight razor from his pocket, he cuts his mother's throat to end her suffering. He then blocks out the memory and attributes her death to suicide.

Traumatized, Amadeus puts on his mother's wedding dress and takes out the pearl-handled razor. It is vaguely implied that Arkham cannibalizes his family's remains in a shamanic ritual.^[78] Kneeling in the blood of his family, he vows to bind the evil spirit of "The Bat", which he believes inhabits the house, through ritual and sorcery. He treats Hawkins for months until finally electrocuting him in a shock therapy session. This incident is treated as an accident by the authorities. Soon after, Arkham freefalls into madness. He continues his mission even after he is incarcerated in the Asylum himself after trying to kill his stockbroker in 1929; he scratches the words of a binding spell into the walls and floor of his cell with his fingernails and constantly belts out "The Star-Spangled Banner" in a loud voice until the day he dies.

Decades later, Dr. Cavendish, another doctor in the asylum, believes he is a reincarnation of Amadeus and frees the inmates. Towards the end of the story, he takes another doctor, Dr. Adams, hostage, dresses himself in the dress of Amadeus' mother and relates Arkham's history to Batman before attempting to strangle him. Adams saves Batman by killing Cavendish with the same razor Amadeus used to kill his mother.

Amadeus' role in creating the asylum, Hawkins' history with Amadeus and Amadeus' descent into madness have become canon and are the origin of Arkham Asylum in all incarnations of the asylum since.

In The New 52 reboot, Amadeus Arkham is re-established as having been the partner of Jonah Hex. Amadeus is a psychologist who specializes in criminal behavior and lives in a mansion with his mother. Amadeus works with Hex in an effort to solve a series of murders committed by the Gotham Ripper and uncovers a child slavery operation run by the Court of Owls.^[79]

She befriended the incarcerated supervillains and would sit outside the Joker's cell to read fairy tales with him, growing to idolize the knights in these stories. Astrid developed a grudge against Batman and saw him as a demon that tormented her friends. This grudge turned into hatred when she uncovered video tapes of Ingrid being struck by a batarang. Believing that Batman had murdered her mother, Astrid trained to become a skilled fighter and, inspired by the knights in her bedtime stories, rechristened herself as the Arkham Knight to seek revenge against Batman.^[84][85][86]

After a brutal fight (during which the Dead King manages to claim Aquaman's Trident) Aquaman freed Mera and the rest of the Xebelians, but they sided with the Dead King, recognizing him as the true ruler of Atlantis, except for Mera. They managed to escape to Atlantis, but found it being attacked by the Scavenger's fleet. During the battle, the Dead King and the Xebelians arrived and he managed to cause Aquaman to black out, using his Sceptre and Aquaman's Trident. After being in a coma for six months and soon discovering the Dead King's origins with the help of Nuidis Vulko, Aquaman returned to liberate Atlantis from the Dead King and the Xebelians, using the Dead King's relic Scepter and the Trench. When the Dead King grabbed the relic Scepter and struck at Aquaman, Vulko tried to prevent the Dead King from killing him, saying that Aquaman was the rightful king of Atlantis, causing the Dead King to become so angry that he attempted to destroy all of Atlantis, but Aquaman stopped and destroyed the Dead King, along with the relic Scepter. The battle ended when Aquaman reclaimed the throne once again.

Atlanna is a character appearing in American comic books published by DC Comics.

Atlanna is the mother of Aquaman in the Silver Age of Comics and the post-Crisis on Infinite Earths comics and the wife of lighthouse keeper Thomas Curry.

In post-Crisis on Infinite Earths continuity, Atlanna was retconned as the Queen of Atlantis. After a dream-affair with Atlan, Atlanna became pregnant, but died in prison from illness. Afterwards, Charybdis revives her as a mermaid.

In 2011, The New 52 rebooted the DC universe. Atlanna is the jaundiced queen of Atlantis and mother to both Arthur Curry and Orm Marius. The post-Flashpoint incarnation of Atlanna is a runaway from home after an arranged political wedding to much hated Orvax Marius of the Atlantean navy was decreed by her nation's parliament. It was during her great escape she met and fell in love with a lighthouse keeper named Thomas Curry while witnessing his bravery during a harsh storm out at sea. The two cohabited and would parent the future king of Atlantis; Aquaman. When young Arthur Curry began to manifest a rapport with the native marine life in the sea around their ocean side home early on, Atlanna was resigned to return home and face her duties as royalty under the crown.

She would marry her betrothed who now sat on the throne of the undersea nation as king, fathering a second child to him called Orm Marius, one who would later ascend to monarchy in later life. Her time as queen was rather horrid however as her spouse was abusive and power-hungry, often abusing his leadership to sanction raids on human-made vessels to spite those who made residence on land. On top of physically assaulting his lawfully wedded wife, Orvax cheated on his royal spouse, having fathered a second child named Tula with another woman at an unknown date. After finally gathering up the courage to leave her wretched life as Queen of Atlantis behind and be with her first love and other son, her king cruelly jested that he had had them killed by his military force just so she would avoid leaving him; this enraged Atlanna enough to kill him dead with her own royal scepter and make it look as though an assassin had done the deed when Orm came in on them. As Orvax's deranged rule had no shortage of enemies, this was what people believed.

During her second son's maritunis, Atlanna had faked her death during a freak accident while on stage, something which many people thought Orm secretly engineered to usurp the crown early on. She would finally leave her servitude to a nation she had hated for taking what she cherished most by using forgotten knowledge of Atlantean magitek to found her own secret nation of Pacifica, an extra-dimensional refuge for downtrodden mariners like her.

When her long-lost surface born son came looking for Atlanna, she adamantly rebuffed his claim of parentage. Believing her Arthur to be long dead, she sought to sacrifice Arthur and his wife to Karaku, a volcanic entity of colossal proportions. Aquaman managed to escape just as Atlantean reinforcements came through the Maelstrom; at the same time, Karaku the volcano god descended and attacked both sides with fire trolls. After a hard-won fight against the lava titan, Arthur would display his skill of marine telepathy which she herself possessed to prove himself. Atlanna then broke down in tears, realizing her son was well and truly alive, before sending him back to Earth with her Shell of Sounds.

In the present, Arthur and Mera encounter Atlanna while seeking out the Trident of Atlan. After joining them in escaping the Hidden Sea and thwarting Ocean Master's attempt to wage war on the surface world, Atlanna reunites with Thomas.

Aurakles is a superhero appearing in American comic books published by DC Comics. He first appeared in Justice League of America #100 (August 1972), and was created by Len Wein and Dick Dillin. He was originally named Oracle, but was renamed to Aurakles in Seven Soldiers: Mister Miracle #4 (May 2006).

Aurakles was created on the planet Earth by the New Gods around 40,000 BC and is generally considered "the original superhero", by those who know his reputation. He has the mission to "bring order and meaning where incoherence reigns". Opposing the evils of his time, he battles the Sheeda and Nebula Man. The Sheeda finally succeed in imprisoning Aurakles in their "bone prisons", set up in the ancient past.

Aurakles reappears in modern times as the Oracle. When the Justice League of America and the Justice Society of America work together to bring back the time-lost Seven Soldiers of Victory (themselves victims of Nebula Man), they invoke the Oracle (in spiritual form) as their guide. It takes the combined magic of Doctor Fate (Kent Nelson), Zatanna, and Thunderbolt to summon him. Oracle refuses to give direct answers to their questions, but helps them solve the matter for themselves. He sends them to the various places in time where the Seven Soldiers have been exiled.

Some time later, Aurakles is freed by Mister Miracle (Shilo Norman) when the latter opposes Darkseid, Nebula Man, and the Sheeda as a member of the new Seven Soldiers. Aurakles' golden tomb on Mars is also seen in Grant Morrison's version of Frankenstein.^[121]

The rookie heroine Bulleteer is Aurakles' descendant and "the spear that was never thrown", one of "seven imperishable treasures" used to combat the Sheeda.
