Ul’Thakar

Ul’Thakar Darkness is the Infinity who embodies Darkness and rules its Supreme World. Aggressive, proud, and sustained by the Universe’s fear and destruction, he becomes one of Nux’s principal opponents while repeatedly showing that his love of battle does not override his instinct for survival.

Biography

An unknown enemy and an ancient stalemate

Ul’Thakar enters the conflict after the disappearance of Supreme Borns from all four ruling factions convinces the Infinities that the Anomaly may command powers from another universe. Orravyn needles him to enter the enemy universe through darkness, appealing to his reputation for bravery and conquest. Ul’Thakar refuses to become the first test subject. Like the other Infinities, he fears that the apparent opening may conceal several unknown Infinities, and he values his life more than proving a boast. His initial position therefore establishes the limit beneath his aggression: he welcomes dangerous combat when he can judge it, not a blind gamble from which his rivals might profit. (Chapter 2130)

That caution sits within a much older deadlock. Ul’Thakar wants the Absolute Power of the Universe and claims that, once he possesses it, he could defeat the Anomaly and conquer other universes. Equarios rejects the promise as unsupported and declares Ul’Thakar too prideful and impulsive to hold such authority. Ul’Thakar answers by naming Equarios a coward who disguises fear as calculation. The argument exposes both his ambition and the pressure restraining it: no Infinity can fight the others without risking catastrophic damage to the Universe and leaving the victor vulnerable. Even while strengthened by the fear surrounding Nux’s attacks, Ul’Thakar cannot safely convert that advantage into sole rule. (Chapters 2212–2214)

Ul’Thakar consequently accepts collective planning without surrendering his rivalry. He supports defending High-Level Worlds and drawing out Nux’s real forces, but opposes involving Azriel, whom he assumes is aligned with the Anomaly. He is bored by deliberation and wants a challenging fight, yet privately refuses to move first while the other Infinities remain safe. His choice helps preserve their stalemate while also allowing Nux time to grow—the precise danger the meetings are meant to prevent. (Chapters 2215–2218)

A united front and war with Light

When the four Infinities manifest physically to address the Universe, Ul’Thakar puts his hostility toward Seraphielle aside long enough to present Nux as a foreign invader. He admits that the Supreme factions have fought for growth and calls on them to direct that conflict outward; the four publicly declare themselves one force. This unity is strategic rather than reconciliatory. Ul’Thakar and Seraphielle remain the oldest active enemies in the Universe, and their opposing natures make even their physical proximity strain the void around them. (Chapters 2219–2222)

The alliance frays as Nux’s campaign damages Light. Ul’Thakar mocks Seraphielle for closing her worlds and for the suffering that decision causes, while privately benefiting from the fear, anger, uncertainty, and helplessness spreading through the Universe. Those emotions strengthen Darkness until he becomes the strongest of the four current Infinities, though Darkness has a ceiling and cannot grow without limit as Chaos can. When Azriel contacts the group, Ul’Thakar’s resemblance to the newcomer in arrogance makes the exchange especially volatile: he challenges Azriel to meet him alone, and only Equarios’s reminder that they still need information makes him master his temper. (Chapters 2287–2289 and 2293)

Azriel then weaponizes the Infinities’ distrust, suggesting that one of them may secretly support Nux. Seraphielle turns the suspicion into an ultimatum and declares war on Darkness. Ul’Thakar accepts, beginning a clash powerful enough to damage a specially reinforced void and pull both factions into a wider war. Although the ambient misery favors him personally, Seraphielle’s prepared opening destroys vital Darkness Worlds and infrastructure; the loss of Darkness’s own followers can weaken him despite the general increase in death. Ul’Thakar’s faction therefore gains power from war in principle while paying severe material costs for his decision to fight it. (Chapters 2290–2293 and 2301–2302)

From rivalries to the Anomaly trap

Equarios and Orravyn interrupt the Light–Darkness war only because Zylarith offers information too consequential to ignore. Ul’Thakar initially prepares to expand the confrontation, then listens when told that Nux is Zylarith’s “son,” has grown from a mortal in only millennia, and can devour worlds to increase his strength. The revelation reframes Ul’Thakar’s opponent from an irritating foreign raider into a rapidly developing threat capable of ending every Infinity’s plans. He accepts a temporary five-Infinity alliance, though neither side expects loyalty after Nux is subdued. (Chapters 2322–2326)

The alliance captures Vashti, whose projections can notice the temporal blindness surrounding Nux. Ul’Thakar returns when her soul has been made into the Crown of Peace and questions its operation closely. He confirms that his own fate-reading relics cannot reproduce Vashti’s perception and presses Orravyn until Orravyn admits that the exact mechanism behind her superior sensitivity remains unknown. Ul’Thakar nevertheless accepts the device, helps plan its distribution, and looks forward to the hunt without objecting to the torture and soul-conversion that made it possible. (Chapters 2328 and 2332–2336)

Success does not repair the old rivalries. Ul’Thakar openly reassures Zylarith that the four will honor their bargain while all four privately intend to betray him, and he anticipates another war over Nux’s body, soul, memories, and family once the immediate threat is removed. The trap thus achieves operational unity but no lasting trust: Ul’Thakar cooperates because the danger is shared, while still treating every ally and promised reward as part of the next contest. (Chapters 2333–2336)

Execution, reversal, and imprisonment

When Nux battles Zylarith, Ul’Thakar tears open an entrance into Nux’s dimension and brings the other Infinities through. He initially dismisses Zylarith’s warning that Nux could defeat any one of them, then notices how completely the former Chaos Infinity has abandoned pride to urge immediate action. Ul’Thakar becomes the first of the four to insist that they stop arguing and kill Nux. In the ensuing battle he serves as the coalition’s close-range pressure, repeatedly reforming from darkness to strike while Seraphielle accelerates and heals him, Equarios makes impossible advantages carry a price, Orravyn restrains and records, and Zylarith corrupts Nux’s routes. (Chapters 2355–2360)

The cooperation nearly fails when Nux combines several Laws with Anomaly and erases more than half of Ul’Thakar’s body. Darkness cannot disperse the strike, Seraphielle cannot heal it, and Ul’Thakar needs hours to recover; another direct blow would have killed him. Rather than resume their quarrels, the five close every opening and eventually overwhelm Nux. Ul’Thakar joins the process that removes Nux’s unseen traces after Light erases the visible ones, believing that the execution has severed him from every timeline and universe. His victory leaves him injured but apparently vindicates the collective strategy he had once resisted. (Chapters 2360–2365 and 2400)

Nux’s return overturns that conclusion. Ul’Thakar hides as a minute piece of darkness, reforms behind him, and attempts to behead him, but Nux can now seize his nonphysical body and destroy Orravyn’s attempted protection. Unlike the other Infinities, Ul’Thakar does not run or beg when his defeat becomes certain. He asks how Nux survived, tries to fight once more, and accepts that expecting mercy from someone he tried to erase would be hypocritical. Nux removes his ability to die, pulls out his soul, and condemns it to continuing agony before sealing all five captives in inaccessible space. Three thousand years later, Son of Darkness governs in his absence and cannot locate him; Ul’Thakar remains alive, imprisoned, and unable to end his suffering through death. (Chapters 2400–2403)

Appearance and personality

Ul’Thakar’s meeting-body is black light surrounded by ominous energy, while his deeper form is Darkness gathered without a fixed shape or size. When he takes a defined physical appearance, shadow and smoke form a tall, lean man with polished-obsidian skin, black hair, crimson eyes, and red light pulsing like magma beneath his skin. A sentient-looking mantle of mist coils around his shoulders, and his presence consumes warmth rather than merely blocking light. (Chapters 2122, 2213, and 2219)

He is direct, combative, and intensely proud. Ul’Thakar despises Equarios’s indirect phrasing, Seraphielle’s moral performance, Orravyn’s playful evasions, and Azriel’s superior manner; confrontation is both recreation and a means of asserting status. Yet his aggression is not mindless. He can suppress anger when Equarios gives a practical reason, recognizes when Zylarith’s fear is evidence rather than weakness, and avoids unknown battles that would make him another Infinity’s experiment. His composure at final defeat also distinguishes him from his allies: once escape is clearly impossible, curiosity and a last attack replace bargaining for mercy. (Chapters 2130, 2213–2215, 2287–2289, 2357–2358, and 2401)

Abilities and cultivation

Ul’Thakar is an Infinity, a being whose comprehension no longer requires the bounded Domain used by an Eternal. He can impose Darkness directly on reality wherever his authority can reach. The corpus identifies his signature power as the Law of Absolute Darkness, but does not explain how he originally acquired the Law or became the Darkness Infinity.

Law of Absolute Darkness

Darkness is both Ul’Thakar’s substance and his source of authority. Fear, helplessness, anger, and similar negative emotions across the Universe feed it; Nux’s attacks and Light’s repression therefore make Ul’Thakar stronger until he temporarily surpasses the other three current Infinities. This growth is conditional rather than limitless. Darkness cannot expand endlessly like Chaos, and destruction concentrated against Darkness’s own worlds, Eternals, and faction can instead reduce the base supporting him. His strength consequently depends on the state of the wider Universe as well as his own comprehension. (Chapters 2293 and 2301–2302)

He can release darkness over a battlefield, smother warmth and light, and form that darkness into fists, claws, knees, and elbows carrying Infinity-level force. In the five-Infinity battle, these manifestations repeatedly break Nux’s bones even after blocks. During the attempt to erase Nux, Absolute Darkness devours what remains unseen—shadows, echoes, and residual records left after Absolute Light burns visible marks. This latter use is demonstrated as one component of a five-power execution, not proof that Ul’Thakar can erase an Infinity across all timelines by Darkness alone. (Chapters 2219, 2360, and 2365)

Darkness form, dispersal, and movement

Ul’Thakar can dissolve his body into mist or scattered darkness so ordinary physical force passes through without injury, then reform from a minute particle elsewhere. He uses this both defensively and for surprise movement: he lets Nux’s first punch cross his dispersed body, reconstitutes behind him, and lands a blow strong enough to send him through the void. He later repeats the infiltration tactic after Nux’s resurrection by moving a small darkness behind him before forming his claws. No fixed range, duration, or energy cost is stated. (Chapters 2358 and 2401)

The form is not invulnerability. Nux’s Law of Anomaly makes a physical punch damage Ul’Thakar despite dispersal, while a combined attack using Space, Time, Destruction, Chaos, Death, and Anomaly prevents dissolution and erases most of his body. A lesser large-scale Anomaly barrage would naturally require at least half an hour to heal; the combined wound needs hours and resists Seraphielle’s healing. After Nux’s return, he can physically grab Ul’Thakar’s otherwise intangible arm and throat. These are counters demonstrated by Nux’s exceptional Law, not general weaknesses every physical attacker can exploit. (Chapters 2359–2360 and 2401)

Infinity endurance, physical power, and faction authority

Ul’Thakar is the coalition’s strongest direct physical combatant. He tears open the narrow breach into Nux’s dimension with his claws, overpowers Nux at close range, and continues fighting through damage that would remove lesser beings from battle. Seraphielle’s temporary Light enhancement increases his speed and recovery, but those boosts are borrowed support rather than innate Darkness abilities. Equarios’s damage redistribution and Orravyn’s relics likewise preserve him during the team battle without becoming part of his permanent powers. (Chapters 2355–2361)

His will also persists through Son of Darkness, a separate proxy created from Ul’Thakar’s will with part of his consciousness. The proxy can govern Darkness Borns and erase them without seeking permission; in Ul’Thakar’s absence, it carries the faction’s authority as “Darkness.” This is delegated rule, not evidence that the proxy equals Ul’Thakar’s full combat power. By the latest established state, Ul’Thakar’s own soul remains conscious but sealed and tortured, while the proxy governs without knowing his location. (Chapters 2301–2302 and 2403)

Relationships

• Nux: Ul’Thakar first treats the Anomaly as a dangerous unknown, then as an opponent whose raids strengthen Darkness and threaten every Infinity’s future. He helps trap and erase Nux, but Nux returns, overcomes his intangible form, and condemns him to undying imprisonment.
• Equarios: The two are ancient enemies who understand one another’s weaknesses. Ul’Thakar calls Equarios a coward hidden behind calculation, yet he accepts Equarios’s intervention when his own temper threatens their plans and relies on Balance’s damage-sharing during their final alliance.
• Seraphielle: Light and Darkness share the Universe’s oldest surviving enmity. Their mutual disgust becomes open war, but the threat from Nux forces them into unusually effective cooperation in which Seraphielle supplies Ul’Thakar with speed and healing.
• Orravyn: Ul’Thakar distrusts Orravyn’s appetite for variables and his playful manipulation, but accepts his plans when they promise useful action. Orravyn’s relics protect and sustain him in the final battle, though they cannot save him after Nux returns.
• Zylarith: Ul’Thakar mocks the fallen Infinity and intends to betray him after using his information. He nevertheless recognizes the seriousness behind Zylarith’s warnings and fights beside him once Nux demonstrates the threat Zylarith predicted.
• Azriel: Their similarly enormous egos produce immediate hostility. Ul’Thakar challenges Azriel to a direct fight, but postpones it for information; Azriel’s insinuations later help ignite the war between Light and Darkness.
• Vashti: Ul’Thakar participates in exploiting Vashti’s exceptional projection ability after her capture. His questions clarify what the relic made from her can and cannot sense, but he shows no concern for her stripped soul or body.

Items

• Crown of Peace: Ul’Thakar helps evaluate and deploy the network of relics made from Vashti’s soul. The Crown does not directly sense Nux; it detects the otherwise inexplicable temporal blindness surrounding a world he is about to affect and reports through Orravyn’s central Orb. Ul’Thakar neither creates nor personally owns the network, and even Orravyn cannot fully explain why Vashti’s understanding makes the method work when the Infinities’ own fate-reading fails.
