Nabu is a fictional character appearing in American comic books published by DC Comics. First appearing in More Fun Comics #67 in May 1941, he is a major supporting character in Doctor Fate titles. A fictionalized version of the Mesopotamian god of the same name, he frequently serves as the first person to call himself Fate before serving as a guiding force and mentor of several bearers of Doctor Fate, notably being his agents for the Lords of Order. Over time, Nabu is characterized as cold and relentless in his battles against the Lords of Chaos, resorting to manipulating his first apprentice by usurping control of Kent Nelson's mind and body while being the chief cause of Inza Cramer's mental breakdown. This characterization becomes consistent although the character has also attempted to learn from his errors. In modern continuities, while his history of his mental control over Nelson is intact, he agrees to cede control to Khalid Nassour, favoring his newest host.^[1]

Shortly after the formation of the universe, two elemental forces were born: the Lords of Order and the Lords of Chaos. As the two emerged, both forces struggle for supremacy over the other. The Lords of Order manifest as the first sentience race in the universe as disembodied magical beings, in which included Nabu. As a Lord of Order, he was one of the first beings to contribute to the creation of the universe.^[2] Eventually assigned to the mortal world of Earth, he adopted a human form and descended to Earth from Cilia, and became Nabu the Wise, an advisor to the pharaohs of ancient Egypt. He served as a court magician for various Egyptian pharaohs including Khufu and Ramses.

During his time with Ramses, Nabu tried to warn the pharaoh and subsequently his son against persecuting the escaping Jews, led by Moses. One night, Nabu was visited by the Spectre, who warned that every firstborn Egyptian child would be killed by him except for Hebrew slaves. This horrified the magician and he prepared to fight the Spectre with all of his powers but was defeated despite his preparations. The humiliated mystic returned to the pharaoh who had lost his son and, in despair, agreed to free the Hebrew slaves, but then decided to send his army to kill them to annoy God. Despite his plans, the Pharaoh was killed when the Spectre brought the Red Sea crashing into the Egyptian army after Moses and the Israelites had crossed.^[2]

Nabu became the guardian of several powerful talismans, in 2578 BC, when Egypt had fallen under the rule of the Vandal Savage, who had assumed the identity of Pharaoh Khafre. Around this time, Bonnie Baxter of the Masters of Time had come from the 20th century, where Khafre's guards threw her into a prison cell. Nabu appeared before her and led her to safety with his magic and asked for her help in overthrowing the immortal Khafre. He intended to combine magic with the science of the time traveler where she gave him her communicator. By combining the pair, he created the Blue Beetle of Khaji-Da, which Bonnie used to overthrow the pharaoh who was wrapped in bandages to contain him, as his immortality would cause him to rise again.^[3] The Beetle was lost for 4,500 years before being rediscovered in the 20th century by archaeologist Dan Garrett, who became the first Blue Beetle.

During the Theban dynasty, Nabu served as an advisor to Prince Khufu Kha-taar, where he served with his ally Teth-Adam. One day, they witnessed a Thanagarian spacecraft crashed and they headed to catch up, they arrived at the scene of the dying pilots where Nabu conjured a spell to translate their alien language that spoke of imminent danger in the far future after this they died. From the ship, they discovered the existence of Nth Metal, which Khufu forged into weapons for his use, and Nabu tried to prepare them, as it was determined that the prince and his fiancée had a role to play in this conflict. During this time, they encountered a traveler who could travel at high speeds and gave him a war glove forged from portions of the Nth Metal called the "Claw of Horus", which they predicted would be instrumental in a battle of thousands of years in the world.

In 1920, archaeologist Sven Nelson and his son Kent go on an expedition to the Valley of Ur. While exploring a temple discovered by his father, Kent opens the tomb of Nabu and revives him from suspended animation, accidentally releasing a poisonous gas which kills Sven. Nabu takes pity on Kent and teaches him the skills of a sorcerer over the next twenty years before giving him a mystical helmet, amulet, and cloak. In 1940, Kent meets Inza Cramer and Wotan in Alexandria, Egypt on his way back to America. After arriving back in the United States, Kent begins a career fighting crime and supernatural evil as the sorcerer and superhero Doctor Fate and sets up a base in a tower in Salem, Massachusetts. Due to Nabu occasionally possessing him, he converted to half of the helm to regain control but at the cost of halving the power.

After Kent's death, Nabu chooses Eric Strauss and his stepmother Linda to be the next Doctor Fate, with Eric and Linda having to merge into one being to become Fate.^[4] Nabu goes on to possess Kent's corpse to personally advise them.^[4] The three of them are soon joined by a friendly demon called Petey and lawyer Jack C. Small.^[5] Eric is killed on Apokolips during a battle with DeSaad, forcing Linda to become Doctor Fate on her own.^[6] Linda is killed soon afterwards by the Lords of Chaos. Following this, Eric and Linda's souls reincarnate in the bodies of Eugene and Wendy DiBellia while Nabu reincarnates as their unborn child.^[7]

Eventually, Nabu came into conflict with the Spectre when he began hunting down and killing other Lords of Chaos and Order. In Infinite Crisis, Alexander Luthor Jr. revealed that he had sent Superboy-Prime to recover the black diamond and that the Psycho-Pirate delivered it to Loring on Alex's orders and had Eclipso-Loring manipulated the Spectre by convincing him magic was an abomination to God and into breaking down magic into its more raw energy form, in which doing so killed the Lords of Chaos and Order in the process. In doing so, Alexander could use them for his own ends. After killing other Lords of Order including the Wizard Shazam, Nabu was the last one to face him. Nabu put up a valiant fight against the Spectre but knew he would lose this battle and instead, opted to fight at a level for the Presence to take notice. Je was fatally injured but ultimately stopped the Spectre. Nabu, in his final act, passed his Helm of Fate to Detective Chimp and tasked him to find one worthy of the mantle. With his death, the 9th Age of Magic had ended and the 10th Age of Magic begun.

In 2011, "The New 52" rebooted the DC universe. This new iteration of the character featured alterations to his origin story. In the Doctor Fate series, the character's earlier history attributed him to being a servant of Thoth, who created the Helmet of Fate and designated Nabu as the spirit within. The reasons behind this choice are unknown, but Nabu's role was to assist the chosen champion of the Egyptian pantheon, Doctor Fate.^[8][1]

However, an alternative origin was later presented for Nabu in this revised continuity. It depicted his rise to becoming a member of the Lords of Order from a mortal existence. This transformation occurred as a result of his interactions with Hecate, a deity who had suffered abuse from fellow sorcerers, including the notable future practitioner of dark magic, Mordru. As a consequence of the inherent dangers of magic, Nabu's spirit eventually came to reside within the Helmet of Fate as his body deteriorated. While this alternative origin restores his status as the Helm's primary intelligence, it diverges from the traditional depiction of the Lords of Order as ancient energy beings.^[9]

In the Doctor Fate series, Nabu assumes a new role as a guide and mentor to Khalid Nassour, the new Doctor Fate. Nabu assists the inexperienced Khalid in his battles against various adversaries, including Anubis, a necromancer, and the spirit of Julius Caesar. Additionally, Nabu imparts crucial information to Khalid, as well supports Kent Nelson when he resurfaces in Khalid's life after discovering Khalid's destiny as the next Doctor Fate.Nabu is portrayed as a deceased spirit who often communicates in cryptic ways, which fustrates the young Doctor Fate. At times, Khalid dismisses Nabu, likening him to an annoying Jinn.^[8][10][11] For a period, Kent Nelson resumed the Doctor Fate mantle while training Khalid Nassour, but Nabu trapped Kent in mystic stasis. Nabu then assumed the role of Doctor Fate, using Kent's connection to manifest through the Helm of Fate. Nabu clashed with Blue Beetle and his scarab Khaji-Da, orchestrated by their shared adversary, Arion. Kent eventually regained control, defeated Arion, and continued training Khalid.^[12]

In Justice League Dark, Nabu betrays Kent Nelson, taking control of his body and imprisoning Khalid Nassour. Nabu's goal is to eradicate magic and sacrifice the magical community to eliminate the threat of the Upside-Down Man and Hecate. Khalid, Kent, and the Justice League Dark unite to counter Nabu and Hecate, ultimately leading to Nabu giving the mantle of Doctor Fate to Khalid. With Nabu's help, Khalid battles Circe, the Injustice League Dark, restores balance to the elemental Parliaments, and faces the Upside-Down Man. Both Nabu and Kent make sacrifices to aid the team. Though surviving, Nabu is no longer the primary intelligence in the Helmet of Fate. Throughout the series, Nabu's manipulative nature is evident, but he gradually learns from his mistakes and gains respect from Khalid. Kent becomes cautious about trusting Nabu, while supporting Khalid as Doctor Fate.^[13][14][15]

Some time before the battle with Upside-Down Man, Nabu assists Khalid and Superman in battling Xanadoth, a former leader of the Lords of Chaos.^[16] After parting ways with Khalid following the fight with Upside-Down, Nabu reappears to help defeat Xanadoth once more alongside the Justice League and Justice League Dark.^[17] Eventually, Hauhet replaces Nabu as the patron spirit of the Helmet of Fate, bringing her superior wisdom and perspective.^[18] Future State hints at a connection between Nabu and Hauhet, with Hauhet considering herself wiser than him.^[19]

Nabu, a sorcerous entity composed of pure magical energy and a key figure in the Doctor Fate mythology, is widely recognized as one of the most powerful beings on Earth. Among the esteemed members of the Lords of Order, Nabu holds a position of great power and influence. However, his capabilities are rivaled by other notable sorcerers such as the Phantom Stranger and Arion, the former who serves as an agent of the Presence and the latter a fellow Lord of Order and a hailed Sorcerer Supreme, respectively.^[20][21] Boasting an immeasurable reserve of magical power, this character possesses the ability to perform virtually any mystical feat. These powers encompass mind reading, interdimensional teleportation, and various others. Additionally, Nabu possesses inherent immortality and a degree of superhuman strength.When residing within the Helm of Fate, Nabu can establish communication with the wearer, provide visions, interface with computers, and even exert influence over the wearer's will.^[1][22]

While Nabu possesses considerable might, his power is surpassed by the Spectre, the embodiment of divine vengeance and justice.^[2] The character also suffers from various imposed limitations overtime, with recent stories depicting him been rendered unable to utilize a human host without their consent.^[1]
