Power Progression

The documented changes below occur across separate encounters and worldlines; they do not form one uninterrupted evolution 644 750.

Stage / Realm / Level	Chapter	Notes
Awakening — Mictlan	442	Awakens after the wounded Alien God enters the abyss beneath its heart. Fires cosmic rays and spreads Fantasy Tree seeds throughout Mictlan.
Stellar-scale evolution — Mictlan	445	Expands from approximately 40 to 100 meters long. Regenerates severed limbs with greater length and hardness, adapting to previous attacks.
Hypothetical Heroic Spirit body — Foreigner, Grand-level mana	448	Devours defeated Servants’ data, reverse-engineers the Heroic Spirit system, and summons itself through a blood-red magic circle.
Alien God ORT — fused successor	449 450	After Kukulkan destroys ORT’s Spirit Origin and vaporizes 95% of its body, Marisbury claims the remaining flesh. The resulting entity has a defensive field that defeats countermeasures developed for the original ORT.
Silk-producing adaptation — Snowfield encounter	643	Develops durable threads that seize Gomorrah and pull her down, threatening to immobilize the flying Beast.
Mantis-like adaptation — Snowfield encounter	643 644	Sheds its burning shell, attacks from underground, and develops serrated arms. Its evolutionary path explicitly differs from Mictlan’s ORT.
Further enlarged form — later South American Lostbelt	863	Appears with six enormous legs; the 200-meter Bridge Giant stands only as tall as one leg. No formal rank is supplied.

Background / History

Earlier Encounters and Suppression

According to Altrouge Brunestud, Proper Human History’s ORT acquired its fifth-ranked classification when a Dead Apostle Ancestor attempted to capture it. Although ORT was reportedly wounded and hibernating, it instantly killed and devoured the intruder. Goldolf Musik recounts another legend in which one Grand and seven Color magi investigated ORT and never returned, leaving its territory forbidden 370.

Mictlan’s history places Camazotz’s struggle against ORT 66 million years earlier. The Aztec Empire’s advanced technology—including interstellar battleships and immortal flesh—could not kill it. Six million warriors were sacrificed to elevate Camazotz into a god; he suppressed ORT and transformed its heart into a sun, but never fully destroyed it 373.

Kukulkan was subsequently created using part of ORT’s heart. Her existence sustained Mictlan while also preserving an indirect route for ORT’s continued survival 448 449.

Competing Plans in Mictlan

Jaguar Warriors hunted Deinos and delivered their internal organs to ORT as energy. Miyamoto Musashi’s presence later forced the hunters to target isolated Deinos more cautiously, slowing ORT’s replenishment 371 372.

Three competing strategies centered on its dormant body. Marisbury wanted to seize it and destroy Chaldea; Daybit initially intended to awaken it, destroy Mictlan, and stop Marisbury and Chaldeas; Chaldea sought to prevent both awakening and fusion while cutting down the Fantasy Tree. Daybit later abandoned his original plan and cooperated against Marisbury 370 371 435.

Awakening and Chaldea’s Battle

Chaldea reached Xibalba and attempted to wound Marisbury badly enough to prevent him from controlling ORT. Four simultaneous Noble Phantasms overpowered his counterattack, but he survived and entered the abyss beneath ORT’s heart. ORT then awakened, forced the combatants to evacuate, and began converting Mictlan into a crystal-covered landscape 441 442.

As ORT climbed to the seventh layer, it regenerated and completed a stellar-scale evolution. Beast Ereshkigal, Space Ishtar, and Mysterious Heroine XX attacked from three directions, severing limbs, shattering its shell, and exposing its core. Yuan Shikai ordered Morgan, Little Da Vinci, BB, and Sion to analyze its distortion field before it could adapt again 445.

ORT subsequently returned as a self-summoned Foreigner with Grand-level mana. Kukulkan intercepted its laser attack on the Chaldea Battleship and became the principal combatant, repeatedly destroying its body without stopping its regeneration 448 449.

Destruction and Alien God Takeover

Kukulkan revealed that she and ORT were mutually immortal: neither could truly die while the other existed. She used Star, Fall from the Universe to vaporize 95% of ORT’s body, destroying its Spirit Origin and shattering her own Spirit Core 449.

The remaining flesh regenerated under Marisbury’s control. He had deliberately relied on Chaldea’s victory because ORT’s death allowed him to claim its body completely. Alien God ORT blocked Artoria Caster’s Excalibur, rendering Chaldea’s previous field analysis insufficient 449 450.

Yuan Shikai ultimately exploited the fusion’s incompatible drives: Marisbury wanted godhood, the Alien God followed its assigned mission, and ORT instinctively destroyed everything. The contradiction destabilized the entity, which smashed through a mountain wall and fled the Lostbelt 451.

Snowfield Encounter

A later revived ORT advanced on Snowfield City to replenish itself from the ley lines. Its Crystal Valley neutralized the defenders’ sinkhole tactics, prompting Yuan Shikai to summon Gomorrah, Beast VI/G, whose touch suppressed ORT’s regeneration 638 639 640.

ORT answered with new adaptations: binding silk, shell shedding, underground attacks, and serrated arms. It cut Gomorrah’s wings and forced her into ground combat. The Great Divine Envoy, Bull of Heaven, Gilgamesh, Alcides, and other combatants eventually joined the assault, pushing ORT into an increasingly defensive position 643 644 647.

The supplied account later credits Yuan Shikai with holding ORT back and dismissing Gomorrah after the incident ended, but does not detail ORT’s final disposition in that encounter 651.

Mystic Eyes Train and Later Lostbelt Battle

In another encounter, ORT’s laser shock wave sent the Mystic Eyes Train into a dangerous midair spin. Yuan Shikai synchronized with Lita Rozay-en and activated her Vengeful Valkyrie Form. ORT evaded his opening flying kick and attempted to seize the transformed train with eight legs; ordinary bombardment left no lasting damage because it repaired itself 734 735.

A later South American Lostbelt confrontation used coordinated long-range support from the other Lostbelts and Aoko Aozaki. Six attacks struck ORT’s exposed legs simultaneously, exploiting the limited coverage of its distortion field. The subsequent account attributes its defeat to Aoko’s preparations and surprise, which prevented it from reaching its third phase 863 864 866.

Appearance

ORT’s body changes between worldlines and through combat-driven evolution 445 644 863.

• Spider-like body: An enormous upright spider with a metallic shell, appearing blood-colored beneath the setting sun 636.
• Mictlan size increase: Grows from approximately 40 to 100 meters long during its stellar-scale evolution 445.
• Mantis-like form: Develops serrated arms after shedding its fire-damaged shell during the Snowfield battle 643 644.
• Eight-legged form: Uses eight legs in an attempted close-range capture of the Vengeful Valkyrie 735.
• Later colossal form: Has six legs individually comparable in height to the 200-meter Bridge Giant, surrounding a core disk 863 864.

Abilities & Skills

Adaptive Evolution

ORT alters its body in response to its environment and the attacks it receives 445.

• Regrown limbs become longer and harder rather than simply returning to their previous condition 445.
• Develops new weapons and hunting methods, including silk, serrated arms, and underground ambushes 643.
• Can evolve specifically to counter an opponent; its Snowfield adaptations diverge from those of Mictlan’s ORT 644.
• Prolonged combat risks allowing it to adapt beyond the defenders’ ability to defeat it 636 863.

Regeneration and Linked Immortality

Mictlan’s ORT can regenerate indefinitely from even a trace of surviving flesh 449.

• Repeated destruction of its body does not eliminate it 449.
• Its survival is linked to Kukulkan, who was created from part of its heart; killing it requires her to accept her own destruction 449.
• Gomorrah’s touch can suppress healing and negate regeneration, leaving shell damage and lost limbs unrepaired during their battle 640 643.
• Whether Alien God ORT retains the same unlimited regeneration is explicitly uncertain to Yuan Shikai 450.

Crystal Valley / Crystal Ravine

ORT deploys a Reality Marble that replaces the surrounding terrain with crystal 638 639.

• Enhances its mobility while restricting opponents who cannot fly 638.
• Crystals resist, absorb, block, and reflect magical energy; they also withstand the heat of Gomorrah’s meteor bombardment 638 639 640.
• Terrain conversion defeats the defenders’ sinkhole strategy 638 639.
• In Mictlan, its awakening spreads Fantasy Tree seeds and produces a Crystal Ravine that develops into a land-devouring Crystal Tree Sea 442.

Spatial Distortion Field

ORT distorts the space surrounding its body, appearing as though it occupies a different plane 445.

• Partially shields it from the combined attacks of Ereshkigal, Ishtar, and XX 445.
• Has limited coverage: coordinated attacks exploit the exposure of its approximately 200-meter-long legs 864.
• Alien God ORT possesses a changed defensive field that completely blocks Artoria Caster’s Excalibur despite prior analysis of ORT 450.

Consumption and Self-Summoning

ORT consumes both energy sources and information, turning defeated opponents into resources 371 448 639.

• Receives energy from Deinos’ organs supplied by Jaguar Warriors 371.
• Targets Snowfield’s ley lines to replenish its newly revived body 639.
• Devours defeated Servants’ Heroic Spirit data and reverse-engineers their summoning system 448.
• Summons a hypothetical version of itself as a Foreigner with Grand-level mana 448.

Cosmic and Physical Attacks

ORT combines destructive energy projection with close-range predatory attacks 442 448 643 735.

• Fires cosmic rays upon awakening 442.
• Its self-summoned body launches a laser with a projected temperature of approximately 5,000°C 448.
• Spider legs inflict deep penetrating wounds on Gomorrah 640.
• Durable silk can bind and pull down a flying opponent; evolved serrated arms can sever wings 643.
• Can evade an incoming aerial attack and immediately counter with a multi-legged capture attempt 735.

Relationships

• Kukulkan — Created from part of ORT’s heart and an extraterrestrial information-memory entity. Their linked immortality makes her both a source of its continued survival and the combatant able to destroy it at the cost of her own Spirit Core 448 449.
• Camazotz — Ancient opponent who suppressed ORT and turned its heart into Mictlan’s sun, then continued preparing countermeasures for millions of years 373.
• Marisbury Animusphere / Alien God — Seeks ORT’s body as a vessel. Exploits its defeat to become Alien God ORT, but cannot fully reconcile the fusion’s competing intentions and instincts 371 449 451.
• Daybit Zem Void — Initially plans to awaken ORT as a means of destroying Mictlan and stopping Marisbury and Chaldeas; later changes course and cooperates with Chaldea 371 435 441.
• Yuan Shikai — Recurring opponent and strategist who coordinates field analysis, summons Gomorrah, and pilots the Mystic Eyes Train against it 445 638 734 735.
• Gomorrah — Beast VI/G opponent whose regeneration-negating touch counters ORT’s healing, provoking further combat adaptations 640 643.
• Jaguar Warriors — Supply energy to dormant ORT through Deinos organs, but resist its awakened advance with machine guns 371 442.
