[[caption-width-right:350:Mafia Jaguar Warrior]]

Strange humanoid gunmen led by Izcalli who attack everyone they see. They first appeared in the Lostbelt alongside Daybit Sem Void, and have been since kidnapping Deinos and stripping their body parts for resources while ritualistically offering their hearts to Tezcatlipoca. Their capital Mexico City lies in the fifth strata of Mictlān.

[[caption-width-right:350:The Last Emperor Of the Aztecs]]

A mysterious human boy wearing Puma clothing and wielding guns. He is the leader of the Ocelomeh and the king of Mexico City, whose true identity is kept secret for most of the Lostbelt's story.

* BullyingADragon: He makes the mistake of pissing off U-Olga Marie [[spoiler:by gunning down Nemo Marine 4]] and claiming he has that right by virtue of being AboveGoodAndEvil as Tezcatlipoca has been teaching him. She refutes that "logic" by killing all his Ocelomeh minions to the point they turn to ashes and frying him with a single attack.
* {{Foreshadowing}}: Izcalli is the only member of the humanoid Ocelomeh who can speak and understand the languages of Proper Human History. [[spoiler:After all, he ''is'' a prominent historical figure from Proper Human History]].
* HistoricalPersonPunchline: Played for Drama. Late in the Lostbelt's story, Tezcatlipoca reveals Izcalli's true identity to be none other than [[spoiler:[[UsefulNotes/SpanishConquestOfTheAztecEmpire Moctezuma II]], the unfortunate ruler of the Aztec Empire during its fall to Hernán Cortés' conquest. Having felt pity for his betrayal and terrible end, Tezcatlipoca had summoned Moctezuma into the South American Lostbelt for a second chance at life.]]
* InconsistentSpelling: Izcalli or Ixcalli? [[spoiler:Moctezuma and Montezuma are also valid and popular spellings of his True Name (among many), but the Japanese reading leans in particular towards "Motecuhzoma" (モテクソマ - mo-te-ku-so-ma).]]
* PrettyLittleHeadshots: [[spoiler:In the end, Tezcatlipoca shoots him in the face. It's ''impressively'' clean, just a red dot on his forehead.]]
* TraumaCongaLine: The second half of the chapter sees him slowly learn that damn near everything he knows is a lie, and how it doesn't exactly do wonders for his mental health. [[spoiler: From the reveal that Tezcatlipoca has actually helped every side to the point that the king of the Deinos is also an incarnation of him, to Tlaloc not really being the protector god of his city (though she manages to fix that later, he's already dead by that point). And when he finally finds himself unable to follow through with the plan to awaken ORT as he wants to give the Ocelomeh a future, Tez just kills him on the spot.]] His only consolation is that [[spoiler:Tez offers him proper respect for proving he wasn't a failure as history condemned him as, not that it saves him from a bullet through the brain.]]
* YouHaveFailedMe: {{Downplayed}}. [[spoiler:Tezcatlipoca actually [[VillainRespect gives Izcalli props]] for sticking to his convictions about why he refuses to sacrifice himself to awaken ORT, even acknowledging his reasoning and admitting that it's for the best Izcalli didn't sacrifice himself since his wavering resolve wouldn't ignite ORT into destroying the world as Daybit needs it to, and that Izcalli was truly worthy of the title of Tezcatlipoca. Of course, this still means Izcalli is now a liability and has got to go, so Tez doesn't hesitate to gun him down.]]
* YourDaysAreNumbered: [[spoiler:Tezcatlipoca summoned and gave Izcalli a living body by sacrificing his lung, but the god notes after [[YouHaveFailedMe doing away with him]] that Izcalli would have expired on his own regardless of not being sacrificed soon enough anyways due to the nature of said creation.]]

[[caption-width-right:350:Ultimate One of the Oort Cloud]]

The [[UltimateLifeform Ultimate One]] of the Oort Cloud; Ultimate Ones being the designation for the most powerful singular entity of a heavenly body, as well as the vessel of that body's will. In the distant future, the dying Gaia will call out to its siblings in the Solar System to exterminate humanity as revenge for them outliving it on its corpse. ORT responded early, landing in South America in 5000 BC, and fell into a deep slumber awaiting "[[Literature/AngelNotes the promised time]]" when it will be properly awakened by Gaia's death wails. In ''Fate'' timelines, ORT continues to sleep peacefully; however, in the ''Tsukihime'' timelines, it is stated it will eventually wriggle towards awakening.\\\

Across all timelines, there have been a few foolish attempts to kill or capture it, all of which have failed without ORT properly awakening (much like how one groggily smashes an alarm clock before going back to sleep). These failed attempts include the 5th Dead Apostle Ancestor (leading to ORT being awarded the seat ''in absentia''), and an expedition of seven of the most powerful mages of the Mage's Association. As a result of these incidents, the Crystal Valley in which ORT resides has been marked as a forbidden land by all power players.\\\

This is not the ORT of Proper Human History, but a Lostbelt recreation. For more information on this monster, [[Characters/FateGrandOrderORT see its entry for more details]]. Be warned for unmarked spoilers.

* TheImmune: All of them are immune to Mors infection thanks to their gifted Names, making them some of the few capable fighting Mors in the Lostbelt.

* SpellMyNameWithAnS: The English localization uses "Mors", while the Material book shows the name can be read as "Moss".

* MakeMeWannaShout: Her primary form of attacking and Noble Phantasm is Scream Eleusis: Thou Art the Harvest that Reaps the Stars, a massive shockwave that ploughs the earth and destroys entire cities with each usage.

* AdaptationalUgliness: An InUniverse example. Likely due to only being made to be a living MookMaker, the Echidna of the Atlantic Lostbelt is much more groeseteque in comparison to her Proper Human History counterpart who, while still a monstrous snake woman, [[https://static.tvtropes.org/pmwiki/pub/images/echidnaphh.png is much easier on the eyes]].

* NonStandardCharacterDesign: Despite being the head of the Earth Clan, Spriggan looks nothing like them. Earth Clan faeries are depicted as your standard fantasy dwarves, but Spriggan looks much taller and has more humanoid proportions. You would think he would be Wind faerie without wings, but design wise he looks out of place with the rest of the new characters, that he looks notably more Eastern by comparison. [[spoiler:It turns out he's not a faerie at all. He's a human, which explains why he doesn't look anything like an Earth faerie.]]

** [[spoiler:Upon realizing her true nature as someone who will unthinkingly kill even the one faerie in Britain capable of fending off the incoming Calamity just because that person was stealing the spotlight from her, he calls Aurora a monster. He may be a schemer who casually betrays and backstabs those in power for self-gain eventually, but he at least values order, stability, and, most importantly, a working government during a crisis.]]

* ConservationOfNinjutsu: In the Lostbelt Prologue, a small strike team of them are virtually unstoppable, effortlessly massacring Goredolf's army and requiring all of Mash's strength just to fight off a small group of them. By contrast, in Anastasia, where they are fare more numerous, while still dangerous they become much easier to deal with.

->'''Class:''' Foreigner as a base, but can change freely; Grand Foreigner as a Servant

This is not the ORT of Proper Human History, but a Lostbelt recreation. Within Daybit's Lostbelt, the Yucatan meteor with Malla (the microorganism precursors to the Mesoamerican gods) landed ''way'' earlier at 300 million years ago instead of 66 million years ago in the impact that killed the dinosaurs. This allowed it to use its energy to nurture and evolve life in the Lostbelt, unlike in Proper Human History where it was spent repairing the damage caused by the impact. However, Malla's earlier arrival caused ORT to arrive earlier as well. Malla foresaw the incoming disaster and created the underground world of Nahui Mictlān as a safe refuge. ORT's crash-landing in 66 million BC devastated the surface, but the impact didn't stop until it ended up all the way at the very bottom of Mictlān, entering a deep sleep to recover from its wounds.\\\

Humanity eventually evolved into existence far earlier than in Proper Human History, creating the technologically advanced kingdom of Ka'an. Then 6 million years ago, "the promised time" came: ORT finished recovering and began its rampage. Despite this humanity's technological progress, ORT was utterly unstoppable; faced with inevitable extinction, every single remaining member of humanity killed themselves in ritual sacrifice to empower their king Camazotz into an immortal god. Now unable to die, Camazotz battled the alien monster for eons [[DeathOfAThousandCuts until he eventually wore ORT down enough to rip its heart out of its head]], followed by Malla tricking it into thinking it still had its heart, sending it into a deep slumber.\\\

The crisis over, Malla was left with an interesting situation. One of the casualties of ORT's assault was the Tree of Emptiness, which it consumed and is now mimicking, turning ''it'' into the force maintaining the Lostbelt. With vanquishing or evicting the Ultimate One no longer an option, Malla had no choice but to try and keep ORT asleep, and so hatched a plan: they repurposed the removed heart of ORT as Nahui Mictlān's Sun, leaving ORT's "corpse" under the ruins of the Tree of Emptiness in depths of Mictlān where no one would dare disturb it. But ORT's slumber, however long it is, is temporary; it recovers its strength even now, awaiting the time when it could awaken to reclaim its heart and finish the job.\\\

ORT was first mentioned in the material book for ''Tsukihime'', and has since lingered in the background for many Type-Moon works. It finally made its first onscreen appearance in Lostbelt No. 7, due to the Foreign God trying to fuse with it in an attempt to gain an even more powerful body. Meanwhile, Daybit sought to awaken ORT to have it devour the Foreign World CHALDEAS and foil Marisbury's Grand Order, as Daybit considered the outcome of Marisbury's plan to be a ''worse'' fate for Humanity than extinction. Once it is fully awakened by Daybit's sacrifice, it becomes the main antagonist of Lostbelt No. 7 "Forest of Emptiness Travelogue, ORT Xibalba."

* AbsurdlySharpClaws: In gameplay ORT's critical attack is to use its giant claws to slam and crush an entire row line of Servants with ''extreme prejudice''.
* AdvancingBossOfDoom: When ORT finally awakens at the Lostbelt's climax, it is still missing its heart -- ''and it wants it back.'' The following chapters are a frantic ChaseFight as Chaldea does everything it can to slow it down and destroy it before it can reach its heart, lest the world be doomed.
* AlmightyIdiot: The decisive factor which led to its loss against Lostbelt Camazotz. Despite its enormous powers and ability to gain the traits of lifeforms it devours, at its base state it didn't have any way to defeat a Beast; who all come with conceptual NighInvulnerability, and it couldn't conceive alternative approaches other than AttackAttackAttack. In contrast, its heart Lostbelt Kukulkan gained full cognizance upon becoming a god, and is capable of self-reflection and making difficult decisions.
* AlternateSelf: This ORT is initially mistaken as the real one from Proper Human History, but in truth its the Lostbelt version that's changed by eating the Tree of Emptiness and then losing its heart.
-->'''Sion''': This ORT is different from the one in Proper Human History. It's adapted to the "WhatIf" history of the Lostbelt. It's inferior to ours in both output and destructive instincts. You could call it an ORT subspecies.
* AlwaysABiggerFish: It is the biggest fish in regards to F/GO. The climax of Lostbelt 7 makes it clear that everything else in the franchise from Gods, to Beasts, to Grand Servants, everything absolutely pale in comparison to the Ultimate One of the Oort Cloud.
-->'''Dumuzid''': Ereshkigal, you did well.... You fought so hard you became one with Kur...no, it would be no exaggeration to say that you were fighting as Kur itself. You would have even repelled the vanguard of a civilization-reaping planet. But this time it was just a bad match up. Truth be told, that thing eats planets. It couldn't have been defeated by anything from Earth.
* AmazingTechnicolorBattlefield: The final battle against Grand Foreigner features a vividly psychedelic stream of color in the background, which changes every time its bar is broken.
* AntagonistTitle: After ORT awakens in full, the title of Lostbelt 7 changes from Golden Sea of Trees Travelogue, Nahui Mictlān, to Forest of Emptiness Travelogue, ORT Xibalba, as it terraforms the entire Lostbelt into its Crystal Valle.
* ApocalypseHow: ORT can literally end the world in seconds if given the chance, its nickname, besides being "The Spider", known as the "Planet Eater". The reason it doesn't right away is because its missing its heart; even then, it waking up angry and merely traversing throughout Nahui Mictlan layers ended up wiping out nearly all life in the Lostbelt. Below is a frightening excerpt as ORT starts its journey towards its heart and transformed the terrain into its Crystal Valley dimension, its seeds spreading:
--> '''Narration''': The end arrived without mercy. The end arrived without cause. No longer does refuge exist in the underground world. The Fantasy Tree seeds came in droves, ravenously consuming all vegetation as nutrients. They considered all non-plant life as enemies, and attacked them indiscriminately. The animals killed by the seeds were crystalized, and then shattered to become stardust scattering in the winds of Mictlan. Deinos and Ocelomeh alike, all who lived in the forest dwellings lost their lives, powerless to resist.
* TheAssimilator: One of the things which makes ORT so threatening is how anything it kills will be eaten and mimicked. Due to being awakened by Daybit giving it U-Olga Marie's heart, ORT considers her a part of itself and so attempts to absorb her shortly afterwards with its tendrils; and because she is still weakened from trying to regenerate her lost heart, she is unable to muster up enough resistance to fight back, and it's only due to Wak Chan's HeroicSacrifice that she survives the experience -- and even then, with about 30% of her Saint Graph lost. Later on, ORT manages to figure out Servant mechanics to summon itself as Grand Foreigner thanks to all the Servants thrown at it for stalling by Chaldea.
* AstonishinglyAppropriateAppearance: Its body appears to be completely black with blue flames streaming out of it, as well as appearing to have huge amounts of segmented sections within it. Given it's the Ultimate One of the Oort Cloud, aka a spherical asteroid belt surrounding the whole Solar System, this makes sense. The segmentation befits the loads of asteroids in it, the blue flames are reminiscent of comet tails (as comets tend to travel through the Oort Cloud to reach the Solar System), essentially making ORT the living embodiment of the barrier between the Solar System and interstellar space, effectively designating this thing as the ultimate wall between humans and the rest of the universe.
* AtomicSuperpower: From what little humanity can analyze, ORT's cells possess internal nuclear fusion process to provide energy, which just adds to its freakiness. The organ which produces the most energy for its actions is its heart, and ripping it out of its body is how Camazotz managed to defeat it in the past -- it is equivalent to taking out the main battery of an invincible killer machine. Said heart proves powerful enough to function as Mictlan's ''sun'' with an unknown lifespan.
* AttackAttackAttack: ORT usually fights opponents by brute force, either physically or via energy beams. While this is usually enough to win, it fails against Camazotz, a Beast with an ''extremely'' advanced form of immortality from all of mankind sacrifice themselves for his power. Because of this, ORT's efforts to win increasingly devolved into trying to beat down the Beast until it was eventually overwhelmed by sheer attrition and had its heart ripped out. This ''only'' applies to the fight with Camazotz in the Lostbelt's history, however -- when it fights Chaldea at present time, the availability of various preys which can feed ORT's CannibalismSuperpower allows it to gain new techniques and powers at a rate which leaves Chaldea in the dust.
* AwakeningTheSleepingGiant: Supplementary materials state ORT is easily the single mightiest entity on Earth at present, so it's quite fortunate that it's content to spend its time waiting until the "Promised Time" only awakening to destroy anything who enters its domain before going back to sleep. The circumstances of Lostbelt ORT's dormancy are distinct, but Daybit and Tezcatlipoca's objective to awaken it still qualify as this trope as the consequences are still ''apocalyptic'' for the Lostbelt and Proper Human History alike.
* TheBadGuyWins: By all accounts, the Lostbelt that ORT is prominent in was technically one where it succeeded; the very effort of summoning Camazotz took the rest of that reality's humanity sacrificing themselves to accomplish it. As ORT's entire objective is to follow the Earth's request for killing humanity, it had won before Camazotz even managed to attack it, which means fighting it was AllForNothing but as a collective vengeance for their extinction, and in the present fighting it is all about dissolving the Lostbelt more than anything else.
* BarrierChangeBoss: In its raid battle, every time ORT wipes an entire row of Servants, its Class will shift randomly between Foreigner and the seven main Classes, shifting its advantages and disadvantages. On the very final bar of its raid battle, it will shift between these Classes every turn.
* BattleAura: Once it assumes its true form, it creates an aura called the Galactica Supercell, a storm of otherworldly colors spiralling outwards. It's also a sign to stay the hell away from ORT, because the Galactica Supercell is caused by ORT generating so much radiation that it's ionizing the air around it.
* BerserkButton: Proper Human History ORT retaliates to any disturbance of its slumber with swift and fatal retribution for the party ''stupid'' enough to do so. However, this is subverted for the Lostbelt incarnation; it was put to sleep by force after eons of battle and losing its heart, so not only it doesn't mind being awakened, it is actually preparing to do so anyways and as soon as it does, it begins moving to retrieve its heart, regardless of what is in its way.
* BeyondTheImpossible: Want to know how freakishly overpowered ORT is? Not even the Throne of Heroes itself is safe from it.
** Servants are summoned by first creating a container for them before transcribing relevant details about the Heroic Spirit recorded in the Throne of Heroes onto the container. If the Servant dies, that's not supposed to be an issue, as the information about the corresponding Heroic Spirit in the Throne should still be safe and can theoretically be summoned again. Not so with ORT; after devouring Servants, it then piggybacks onto their connection to the Throne to hack into it and steal their information directly, an act likened to ''consuming history itself''. The silver lining is that this works both ways, as if someone does the impossible and kills ORT, the consumed information is returned to the Throne safe and sound.
** It's firmly established that there's no Grand container for the Extra classes; only the original seven classes can be summoned as a Grand. Unfortunately for Chaldea, ORT figures out a way to create the class itself, slots ''itself'' into the seat, and then summons itself after its original body dies. Not only is this absurd because Grand Servants can't normally be directly summoned, but ORT does so with a renewable catalyst (its displaced heart) to ''continuously'' summon the Grand Foreigner after the current Grand Foreigner is slain.
** Being enshrined into the Throne of Heroes is a selective and finicky process determined by the Human Order, and normally the idea of just placing oneself on it would be absurd outside of certain exceptions like Yu Mei-ren, who is able to physically enter it by virtue of being a type of Elemental. ORT however is able to cheat the system by using the ability to simulate alternate timelines that it gained from eating Mictlan's Tree of Emptiness. The moment its living body is defeated, it immediately comes up with a hypothetical timeline in which it managed to become a Heroic Spirit, and then summons that ORT as the Grand Foreigner.
* BishounenLine: Its Servant forms, forged from a relentless drive to achieve victory rather than simply instinctive responses, are way smaller than either its spider exoskeleton or the disk which makes up its original true body. This trope is downplayed since it is actually a lot weaker than its spider forms, but this form is what ultimately convinces Kukulkan that defeating ORT is simply impossible as long as she still exists.
* BizarreAlienBiology:
** See that UFO hanging over its head? That's ORT's true body; the spider form is nothing more than an appendage made from waste cells akin to keratin that will automatically be replaced given time. This is made all the worse by ORT's healing factor, as the mere act of regenerating wounds will give it dead cells to start building another spider-body. The more injured it gets, the more cells it will have to replace in a hurry, which means even more materials for the Spider-ORT to be.
** Life on Earth as humans know it is based on cells with predefined structures and functions. That is ''not'' the case with ORT; every single one of its cells is identical and capable of performing any function needed. There's nothing stopping it from turning one of its arms into another heart save for its lack of intelligence.
* BoltOfDivineRetribution: One of ORT's attacks when its charge gauge fills all the way up is to rain a heavy amount of alien lightning energy on its enemies, appropriately called "Cosmic Ray Burst". Not only is it powerful enough to kill a row of Servants if they are not protected by Evade or Invincibility, but it also removes their buffs and cripples the survivors with NP debuffing effects, ensuring they cannot fight back with their Noble Phantasms.
* BreakingOldTrends: It's the first non-Servant enemy with the Star attribute. And while it's not the first enemy with more than four health bars -- Kirschtaria beat ORT to it -- its Servant form is the first proper boss where you have to go through more than four health bars in a single encounter, totaling seven. Finally, it is the only single player raid boss that is fought in the main story - all other single-player raids are encounters in events.
* BroughtDownToBadass: ''Twice over''. And it ''still'' manages to be a world-shattering threat regardless of form.
** Camazotz ripping ORT's heart out means it lacks a main battery to really function, essentially operating with the Lostbelt's Tree of Emptiness which it devoured, which is far too lacking and forces it to enter a dormant state to slowly recover its strength and eventually awaken again. It is a process which would have taken an unknown amount of time until Daybit jumpstarts it by feeding it U-Olga Marie's heart. The heart of the Foreign God is still inferior to its own, but it does not make ORT any less of a reality-warping, Servant-eating juggernaut: even like that it shrugs off and plows through everything Chaldea can throw at it, and it ultimately takes them teaming up with the Foreign God herself to do something that can finally destroy its body.
** Its Servant incarnations are vastly inferior to its original body, as is the case for most Servants in the series which are simply degraded copies of the original Heroic Spirits in the Throne of Heroes. But this hardly matters as even this degraded vessel still qualifies as a ''Grand'' Servant in a Class which doesn't even ''have'' a Grand seat by scale of its power alone. By the time ORT summons itself as a Grand Foreigner, it has consumed so many Servants and evolved new methods to cheat death and kill everything, that now being beatable in a straight fight doesn't make it any less dangerous than before.
* BullyingADragon: In Proper Human History, ORT tends to be awoken from its sleep by many who seek to obtain it and its power for their own use. Most don't live long enough to regret it. Amusingly, this is ''completely averted'' by the Lostbelt ORT, as after Camazotz managed to defeat and render its body dormant, absolutely ''nobody'' other than Daybit and Tezcatlipoca is willing to risk its awakening, not even Camazotz who managed to defeat it in the first place.
* CallForward: Astea's warning about how the current humanity will never defeat ORT and that only the next dominant species will have a chance references the A-Rays and Ether Liners, a modified humanity that runs on the True Ether released by Gaia's death as well as Gun God being the last of the old humans. It also doubles as {{Foreshadowing}}, as it's later revealed the Lostbelt's Humanity indeed stood ''zero'' chance of defeating it and all Camazotz managed was defeat it, not ''kill'' it. Even when Chaldea succeeded, they only did so with the help of entities that weren't part of humanity, one of them even born of ORT itself.
* CameBackStrong: After ORT is seemingly ''finally'' killed as the Grand Foreigner, it resummons itself into an even more powerful version of it's previous form known as the Starcell. Fortunately, Kukulkan manages to finish it off before it has the chance to do anything with said power.
* CannibalismSuperpower: ORT has the ability to mimic and gain the traits of lifeforms it devours. In ''Tsukihime'', it devouring the previous holder of 5th rank Dead Apostle Ancestor gave it a taste for blood and all of its powers, which is why it is considered a vampire despite being anything but. In the Lostbelt ORT displays just how ridiculous this ability could get:
** After it consumes the Tree of Emptiness sustaining the Lostbelt, ORT proves it can create even ''more''. Once it awakens and uses its Crystal Valley to terraform the Lostbelt, every single tree in the Lostbelt is replaced with a Tree of Emptiness.
** Using the information gained from devouring a bunch of Servants, it essentially manages to ''hack the World and the Throne of Heroes'', creating a custom class to summon itself as a Servant.
** The above example is also the ''reason'' ORT is explicitly held as impossible for mankind to defeat without outside help - ORT's ability to cannibalize even ''Heroic Spirits'' means that any attempts by the Counter Force to defeat ORT would just ''make it stronger'' by giving ORT new prey to consume.
* ClimaxBoss: Lostbelt ORT is the final major threat faced in the ''final'' Lostbelt, and thus also the final enemy the heroes must face before the story climax. It is also, without question, the single longest and most intense fight in the entire game, functioning as a ''single player'' raid battle where the player uses an entire ''army'' of Servants to try and whittle away at it.
* CombatTentacles: ORT's true UFO body utilizes this as its main method of attacking its enemies, generating golden tentacles from the three holes on the bottom of its body to stretch out and ensnare its victims.
* ControllableHelplessness: The first fight with it halfway through Lostbelt 7 is initially portrayed as strange, but winnable with ORT "only" having 1 Million HP with a weird cluster icon under its HP bar. Then you deplete that health bar and see the fresh hell you're in for: that cluster icon is a new Break Bar that splits into '''nine more''', and the new HP bar fills up to ''10'' million, with each bar past that getting more absurd. It also gains unremovable buffs after the first break that immunizes it to debuffs, fully charges its NP every turn, and doubles its Attack power. Hacking has shown that the fight is ''theoretically'' winnable as ORT has no other gimmicks here, but there is simply nothing in the game that can withstand this onslaught. The fight ends when your party is defeated after breaking the initial Break Bar.
* CosmicKeystone: This ORT ''ate'' the Lostbelt's Tree of Emptiness, which turns itself into the new foundation of the Lostbelt and enables it to claw itself out of the Lostbelt and into Proper Human History, which Daybit and Tezcatlipoca actually count on. Unlike Surtr though, ORT doesn't vomit the Tree back up upon defeat, so killing it means destroying the Lostbelt -- provided one can kill it in the first place.
* DavidVersusGoliath: Taken to its logical extreme in the Lostbelt's history when Camazotz fought it at its original and ''strongest'' state. The only reason ORT didn't obliterate the Mayan god was because he was given an ''incredibly'' powerful form of immortality by his people performing a mass-sacrifice down to the last human, and it didn't have any way to nullify this immortality despite its raw power. It took him ''millions'' of years, like an elephant being attacked by the world's most persistent ant, but he eventually succeeded and ripped ORT's heart out.
* DefeatingTheUndefeatable: Chaldea doesn't stand a chance against ORT in a straight fight, and they know it. It's only after it's revealed this ORT ate the CosmicKeystone maintaining the Lostbelt that they're forced to try anyway, and for all the crazy shit they're picked up over the course of the story, ORT has some crazy shit of its own to retaliate with, ''only worse''. Having the core of ORT itself on their side in the form of Kukulkan is the only reason it's remotely beatable.
* {{Determinator}}: '''''Holy Flipping Hell Yes'''''. While most of ORT's actions are instinctual or a case of JustFollowingOrders (specifically to fulfill GAIA's request to destroy mankind), the final portion of Lostbelt #7 sees ORT pulling out all stops and straight up doing the impossible ''purely out of the desire to defeat the protagonist''. This includes ''hijacking the Throne of Heroes'' '''so it can summon itself into battle''' '''''as the Grand Foreigner'''''. Nasu has stated that ORT will prioritize its own survival above all else and engage in any method it sees fit to live.
* DetrimentalDetermination: Stuck around the Earth of the Seventh Lostbelt after mankind was all but extinct because Camazotz was still technically human, leaving its purpose on the planet still ongoing when it could have left at any time and potentially avoid its eventual defeat and imprisonment.
* DevelopersForesight: Much like Goetia, there are hidden animations built in should anyone hacks the game files to get a playable ORT. [[https://www.youtube.com/watch?v=JhGkZuuwjsg See it in action against a very screwed Tezcatlipoca]].
* DidYouJustScamCthulhu: Camazotz ripping out its heart wasn't enough to actually stop it since it's capable of moving without it, so Malla put it into slumber by sending a signal to trick it into thinking its heart was still in its body. ORT spent the next 6 million years effectively as a car stuck trying to start an engine that's actually missing. Daybit and Tezcatlipoca's plan is putting in a makeshift replacement heart so it can stop banging its head against the wall and finally realize what's going on.
* DramaPreservingHandicap: ORT lost its heart long ago and is using the Tree of Emptiness and U-Olga Marie's heart as vastly inferior power sources. Despite this it still plows through every single obstacle in Mictlan, including multiple Divine Spirits, dozens of Deinos each on par with a Servant and armed with modern weaponry, the Foreign God, and even swats aside a full powered Excalibur blast (the same one which can ''OneHitKill'' other world-destroying threats like Sefar and Beasts of Calamity) with contemptuous ease. Given it has evolved new methods to deal with threats and the fact the Lostbelt is now filled with ''many more'' things it can devour to evolve via CannibalismSuperpower, it is already nearly unstoppable even ''before'' it can reclaim its heart. Having both the apparent BigBad and the Lostbelt King on our side is the only reason we have a shadow of a chance.
* TheDreaded: Both the game and the ''entire franchise'' go out of their way to emphasize just how ''feared'' ORT is. The two incarnations of ORT present in FGO are both these:
** For Proper Human History, Kadoc recounts a tale from the 16th century when 7 incredibly powerful mages including a Grand-rank led an ill-fated expedition into the Crystal Valley. Only the Clock Tower Lord Astea came back, warning humanity to never again disturb ORT before turning into crystal on the spot. Amongst the nobility of the Clock Tower like Goredolf, ORT's name is used as a boogeyman to get mischievous children back in line.
** In the Lostbelt, nobody other than the U-Olga Marie before losing her memory, Daybit, and Tezcatlipoc is thrilled at the thought of it awakening. When Tezcatlipoca uses his RealityWarper powers to briefly materialize a possible future of its awakening, everyone is understandably nervous of it. Even ''Camazotz'' who defeated it the first time doesn't fancy his chances of doing so again, and wanted to prevent it from happening.
* DuelBoss: In its final fight when brought down to its very last Break Bar, ORT Xibalba will gain massive Damage Reduction buffs and start throwing out OneHitKill after OneHitKill every turn until only the Servant at the front of the player's formation remains. The counter to this is that the remaining Servant will receive their own slew of buffs every time the OHKO is used, incentivizing the player to keep everyone alive until then so the remaining Servant can punch through the DR.
* EarlyInstallmentCharacterDesignDifference: Its character design is notably different from its earliest design. This is [[JustifiedTrope justified]] out-of-universe as the last time ORT appeared in any capacity was '''''22''''' years ago and its appearance was only shown in materials, and in the story itself it is also justified because its spider body can be reconstituted however ORT needs it to be.
* EldritchAbomination: It's an alien lifeform so removed from the World's laws, to the point its surroundings are transformed into Crystal Valley which embodies its native homeworld's own laws. Mash speculates it might take another 1000 years before human technology is capable of analyzing it.
* EvilIsNotAToy: U-Olga Marie entered the 7th Lostbelt with the intention of acquiring ORT's power for herself. Though she ends up [[LaserGuidedAmnesia losing her memories]] plus [[WorfHadTheFlu a good chunk of her power]] long before an actual confrontation, when Tezcatlipoca materializes a FlashForward vision of ORT's awakening she tries to attack it with her black hole, [[WorfBarrage only to do barely anything to it]] and being overwhelmed by its retaliation. Once the future vision ends, Olga is left horrified by the scale of ORT's power and capacity for destruction.
* {{Expy}}: Of [[VideoGame/ChronoTrigger Lavos]] as a super powerful unfathomably old huge insect-like alien entity that crash landed onto Earth in the ancient past, slumbering away until a certain time arrives. Its specific function with the plot is intertwined in exploring an AlternateTimeline in which LivingDinosaurs are now in competition with humans to determine who will ultimately get control over Earth's history and become the permanent dominant species. This is supported by a BadFuture worst case scenario preview by Tezcatlipoca titled "Day of ORT" as a parallel to ''Chrono Trigger'''s "Day of Lavos" demonstrating how both aliens would completely devastate the planet when they fully wake up. The second part just cements it by revealing that, in the Lostbelt's history, it was a meteor that permanently changed the course of history by creating the circumstances to allow for humans to flourish and thrive, just like Lavos did. Even the final battle with it mimics Lavos',with it becoming increasingly more humanoid and copying its foe's systems by the final phase.
* EyesDoNotBelongThere: In its ORT Xibalba form, green eyes are seen ''throughout'' the entity's body, [[https://static.wikia.nocookie.net/typemoon/images/b/b9/ServantORTFull.png/revision/latest?cb=20230728071331 lining up its arms, legs, body, neck and head]].
* FastKillingRadiation: Its body expels so much cosmic radiation that just getting near it is fatal, even for Servants and Deinos. The protagonist requires a makeshift spacesuit given by Daybit just to survive its vicinity. This is reflected in its raid battle where all Servants are given a gradually-worsening MaximumHPReduction. It's even worse in its true UFO form, expelling so much radiation that the air itself is ionized and creating a beautiful but deadly rainbow atmosphere around it. This is played to frightening effect during the story narration; as ORT is slowly but surely getting closer to Mexico City, its coming is heralded by its rainbow storm of death seen creeping up on the screen.
* FinalBossPreview: Tezcatlipoca actually calls his recreation of the possible future of its awakening as this trope. The Lostbelt's Act 1 concludes with Chaldea facing it without proper preparation. It is at level 1 just to show it's not even at full strength, and it still obliterates the protagonists. Fortunately for Chaldea, this gives them the chance to actually prepare for the worst case scenario when it awakens, and rallies pretty much every other party which can be convinced to fight it when it ''does'' awaken. This fight also demonstrates major mechanics at play in the actual fights against ORT; having 1 million HP at minimum, only appearing to have two bars before it reveals it has far more than that number, multi-hit [=AoE=] attacks that inflict unremovable Max HP Down debuffs, and every Servant who dies to it is turned into crystal and eaten by it.
* FinalExamBoss: In a more complex way than normal - ORT's unique ability to change classes every time it wipes a line, as well as how any servants it defeats will be "DATA LOST", means you will have to use ''every trick you have'' to beat it down, while also forcing you to throw ''every single servant you've got at them''. It is noted that canonically, the protagonist threw ''every known Servant to Chaldea'' at it.
* FlyingSaucer: While most people assume ORT is some sort of otherworldly, techno-organic GiantSpider, that's just its ShapeshifterDefaultForm, a projection from its real body that's actually the giant halo/disk. When it disperses the projection in order to travel through the air and space, the disk is very clearly a giant UFO.
* TheFourthWallWillNotProtectYou: ORT's influence in the second half of the Lostbelt's story is seen and felt to terrifying degrees, notably:
** When it fully awakens and uses its Crystal Valley ability to take over the Lostbelt, the main menu glitches out ominously before transforming the green button of the Seventh Lostbelt to a ''red'' button representing its new world.
** During the start of its raid battle, ORT is making its way up the layers of the Lostbelt, ''shown as it walking/running towards the screen'', '''as if ORT will eventually attack you in real life.'''
** The Protagonist's profile picture is not spared from ORT, as during the long raid battle, the Protagonist's face goes from normal, to grim and determined, to sweating and exhausted, to finally terrified and gasping...
** The way it also kills your Servants is entirely unique too to only it, as it is TheAssimilator, ORT will crystalize then absorb the Servants it defeats, which results into them being "Data Lost" and cannot be reused for the duration of the raid. Of course, if you run out of Servants to fight ORT, the game is at least courteous enough to give a SoftReset to the beginning of the raid to allow for the player to better strategize.
** An unintentional example of this is that the raid as a whole puts a ''massive'' strain the poor device you are playing the game on excluding the highest end of devices. Special mention goes to its UFO phase while it is warping space, as the strain of rendering the boss fight would ''drastically lower the framerate'' itself.
* FromASingleCell:
** Camazotz notes even when missing its heart and dormant, its body is still healing itself. Tezcatlipoca further elaborates that ORT doesn't truly have any "vital" organs. Its limbs, nervous system, heart, and brain are all equally unimportant in the grand scheme of things and can be restored in time, compared to a human body having hard limits in what it can heal before it dies, because each cell possesses all of its functions. The main reason it hasn't woken up sooner is because Malla has "fooled" it due to its heart being intact, not destroyed when Camazotz removed it, but that's only slowed down its inevitable awakening.
** Upon awakening and being fought in battle, ORT reveals it goes ''triple fold'': its spider body is nothing more than an appendage for its true body the UFO-like disk, and it being destroyed is only a minor setback as it can be recreated easily; said UFO body is not only incredibly tough but also regenerates insanely fast, to the point even the full power of Earth's Holy Sword can't outpace it. Chaldea needs U-Olga Marie's SuperSpeed Authority to speed up the Rayproof to destroy ORT and even after losing this true body, its detached heart Kukulkan is still an anchor for its consciousness to exist and affect the world so it keeps summoning its Grand Foreigner form endlessly, forcing Kukulkan to sacrifice herself to keep it down for good.
* FunWithAcronyms: Its Servant form indicates that ORT actually stands for '''O'''ne '''R'''adiance '''T'''hing.
* GameplayAndStoryIntegration:
** ORT is explicitly held to be ''completely'' beyond what the Human Order can deal with at the current point in time. When the player first fights ORT, their level is '''''1''''', making it clear that even at their weakest, they're beyond what Chaldea can handle.
** Later it's revealed Camazotz had removed its original heart, so ORT ends up becoming weaker than how it would normally be -- which is why its level is at Level 1.
** When ORT defeats a Servant in the raid battle, it comes with a special animation where the Servant is turned into crystal, shattered, and consumed by ORT. This isn't just flavor; that Servant is now replaced with a '''DATA LOST''' in the menu, ORT having [[BeyondTheImpossible stolen the Servant's information right out of the Throne of Heroes]], and thus they cannot be used again in the raid.
** ORT's mechanics in the raid battle -- preventing stall tactics, wiping the party after a Break Bar is depleted, Mash being restricted every few fights -- ensures that it ''will'' defeat multiple Servants, thereby giving it a means to analyze how Heroic Spirits work and summon itself as Grand Foreigner later.
* GiantSpider: One of the best ways to describe this ''thing''. While it also looks like a huge alien with a giant UFO like appendage over its head, that is mainly for modern day characters. More archaic characters refer to it in this manner and extend the description further; Tezcatlipoca refers to its destruction of the planet as ORT weaving its web. Later on in the Lostbelt, Chaldea finds murals left by the Lostbelt humans depicting their war against ORT, which is portrayed by a giant spider. Moreover, the cylindrical layout of Nahui Mictlān with ORT resting in its depths is evocative of a [[https://en.wikipedia.org/wiki/List_of_trapdoor_spiders "Trapdoor Spider" lair.]]
* GoldColoredSuperiority: It's eventually revealed that the true coloration for its UFO body is gold and its final form as Grand Foreigner is a gold-colored humanoid alien.
* GreaterScopeVillain: The Lostbelt ORT serves as this for Act 1 of Lostbelt No. 7 as it's still sleeping. Daybit and Tezcatlipoca both wish to awaken it for their own purposes, so Chaldea must resolve the situation as fast as possible, or failing that prepare to fight it in a grueling existential battle. Once it's revealed this ORT actually ''ate'' the Tree of Emptiness and became the Lostbelt's CosmicKeystone, it officially becomes the Lostbelt's ArcVillain.
* HoistByHisOwnPetard: What ultimately leads to its defeat. After pulling out all the stops to defeat even this weakened version of ORT, it is still too much for Chaldea and everyone in the Lostbelt. The only reason it is finally beaten is because its still living heart -- which had gained sentience -- blew itself up and TakingYouWithMe. Otherwise, it would have trounced the opposition.
* HopelessBossFight: Act 1 of Lostbelt No. 7 ends with this, doubling as FinalBossPreview. With ''10'' health bars, the first being 1 million HP, the second being 10 million HP, and the third is 100 Million HP. Datamining has shown all of it's HP bars added together adds up to 3,591,250,000. That is over three ''billion'' hp. To hammer in just how outmatched you are, ORT's level in that "fight" is '''''one'''''. To make the point clearer, the "fight" ends with U-Olga Marie attacking it, [[EvilIsNotAToy only for her attack to do as much damage or even less than the other Servants.]]
* HorrifyingTheHorror: '''Everyone''' is scared shitless of this thing. Even the people who want to unleash ORT or [[HijackingCthulhu want to control it]] acknowledge [[GodzillaThreshold that it is an absolute last resort to prevent]] CHALDEAS from completing Marisbury's Grand Order. You know it's bad when the stoic protagonist who has SeenItAll at this point ''has'' to pick the options that form the following lines.
--> '''The Protagonist:''' ''"We've encountered many threats to humanity up until this point, but THAT is a genuine'' '''monster'''".
* InscrutableAliens: Besides answering the call from the planet to exterminate humanity, it has absolutely no way of communicating with Earth's native lifeforms and vice versa, and all aspects to the alien have otherwise been inferred from the few disastrous attempts to interact with it while slumbering. This inability to communicate makes its truly alien mindset unable to really change and adapt to Earth's own sensibilities, unlike various other entities who have encroached upon Earth in the many millennia throughout history, all of which either [[GoingNative adapt to humanity]], have a close enough mindset, or at least have behaviors and languages graspable by humans. Its separated heart ends up pulling a Type Venus and becomes a god with a very human mindset, suggesting it might not be impossible to understand it, but this only happens ''after'' it successfully reduced the Lostbelt's humanity into extinction.
* InvincibleVillain: ORT is considered to be completely invincible by the world of Magecraft, with anyone who tries to mess with it being regarded as TooDumbToLive. Quoth WordOfGod, "If the battlefield is Earth, ORT has no weakness." Here, we finally learn ''why'' this is the case: ORT's CannibalismSuperpower extends to anything it can consume, [[BeyondTheImpossible including Heroic Spirits which are supposed to exist outside of known reality]]. ''Anything'' the Human Order could throw at ORT can become a new weapon in its arsenal, from Counter Guardians, to Grand Servants, to even functions of the Throne of Heroes itself. The only reason Camazotz defeated ORT was because the current humanity was ''already'' extinct except for himself in the process of giving him immortality, leaving ORT with no Human Order to consume, and all the PyrrhicVictory accomplished was merely putting ORT to sleep for a while.
* {{Irony}}: Manages to spoof a Grand-level Class Container, giving it the perfect form to avenge itself against Camazotz, but is defeated before getting a chance to try.
* TheJuggernaut: Good lord, if you thought Tiamat was bad, ''then wait till you get a load of ORT''. Once it's fully awakened by Daybit, it makes a beeline for its lost heart, and barrels through every single layer of Mictlan and their defenses in an attempt to reclaim it. Every time Chaldea and their allies find a way to slow it down or even stop it, it simply adapts itself to keep going.
* {{Kaiju}}: Supplementary materials state ORT can easily grow up to forty meters in height, with no indication this is its maximum size. When fought briefly as a FlashForward FinalBossPreview, it easily towers over our heroes and rivals other giant monsters like ''Tiamat'' and ''Cernunnos''. During the second opening of Cosmos in the Lostbelt, a flash of lightning is seen as Daybit ponders to himself; ORT growing ''rapidly'' in the background. When it finally reactivates fully and sheds its SleepModeSize, da Vinci states it's grown to about ''one hundred'' meters tall.
* KamehameHadoken: When fought as its UFO body, its full charge attack has it generating an avatar of its spider form, before unleashing a ''giant'' beam at its enemies, which will kill your entire row of Servants.
* TheKeyIsBehindTheLock: Chaldea's initial plan was to confirm ORT's location and avoid it like the plague while they destroy the Tree of Emptiness to prune the Lostbelt. Unfortunately, one of ORT's first actions upon awakening in the Lostbelt's pre-history was to ''consume'' it and replicate its function, so now ''it'' maintains the Lostbelt. Goredolf pleads with da Vinci for some way, ''any'' way, to prune the Lostbelt that doesn't involve facing the awakened ORT directly, and she can only sadly reply that there isn't one.
* KillAllHumans: Why it was called to Earth by Gaia, albeit way earlier than expected. It contends with Primate Murder, aka Beast IV, as the best human killer which is why it's classified as a Threat to Humanity despite it being inactive.
* KillItWithFire: How the alien entity ultimately meets its end when Kukulkan sacrifices herself, thus killing ORT's heart and its last remaining lifeline. As Kukulkan blows herself up in a supernova explosion, ORT is engulfed in flames, it and its Crystal Valley dimension burned to nothingness.
* TheLawOfDiminishingDefensiveEffort: When it finally awakens and starts its trek to Mictlan's Sun, ORT effortlessly tanks everything sent its way and when it looks like it's taking damage, it just assumes another form and keeps on trucking along. Then Chaldea fires the Hume-Barrel Rayproof at it, and for the first time ORT actually deflects an attack, proving it's not completely invincible. Of course, that means someone has the unenviable and nigh-impossible task of holding it in place long enough for the attack to land. U-Olga Marie sacrifices her life to do so, and it is shown that while ORT can deflect the Rayproof, it can't ''take'' it.
* {{Leitmotif}}: It's primary and main theme, "[[https://youtu.be/JiyzFL4ROsU Expanding Sun]]", plays whenever the entity takes the stage, its imposing electronic track booming to instill ''hopeless despair'' for everyone who hears it. It first plays when Chaldea fights this abomination in its FinalBossPreview. Then it plays again and again every time the game wants to hammer home that ORT is a ''terrifying monster''. [[note]] Besides its FinalBossPreview mentioned before, the theme plays at key points: when Daybit wakes it up from its long slumber, when its fought again in its SleepModeSize, when it transforms the Seventh Lostbelt into its Crystal Valley home after "waking" up ''angry'', when it "sheds" its defeated spider form and shows off its ''real'', more dangerous form as a UFO and finally, when it comes back as the '''Grand Foreigner Servant''', ''ORT Xibalba''.[[/note]] The spider also has the following themes below:
** ORT's second theme, "[[https://youtu.be/gq9v_qvk3xg Invade Spider]]" is a much harsher and faster arrangement of the first, as Chaldea has to contend with the fact it's legitimately woken up and it's ''pissed''. ORT is then chasing its heart down as Chaldea desperately tries to stop it and slow it down, to little avail. The theme plays one more time when ORT regenerates its spider form on its final health bar, at ''3,000,000'' HP, as the heroes take the battle to near outer space and it grows to roughly to the size of '''Cernunnos'''.
** ORT's third theme, "[[https://youtu.be/8Ivy5wjLSNc Invade Star Cell]]", plays as it engages Chaldea in its true UFO form; the theme adds choir and becomes orchestral even as the electronic music comes and goes as everyone is forced to contend with a highly radioactive, spinning, death machine, that is ''determined'' to kill its enemies.
** ORT's fourth and final theme, "[[https://youtu.be/wCIlBdCITxE Virtualized Earth History]]", plays as Chaldea manages to achieve the impossible and obliterate both its UFO and spider body entirely, with ORT following up by ''copying the Throne of Heroes mechanics'' and then summoning itself as a Servant, '''with a Grand Foreigner Saint Graph container'''. The music shifts the choir into major key, dispenses the electronic elements entirely, and adds piano to demonstrate that the end is absolutely in sight as long as Chaldea can get through ORT's last ditch attempt to cling to life, with both parties holding nothing back against each other in a grand last duel to the death.
* LoadsAndLoadsOfLoading: ORT's initial UFO phase with Galactica Supercell before being hit by Beni-Enma Alter's sword is so effects-heavy that it makes all animations lag and take much longer to load even with fast-forward and double speed enabled.
* LogicalWeakness: For all of ORT's might, it has one flaw in its CannibalismSuperpower: it can't consume what it can't destroy. This is why Camazotz was able to defeat it: because humanity and the Counter Force were extinct at the time, ORT neither had a means of countering Camazotz's extreme immortality nor could it find one. So long as Camazotz didn't give up, ORT's defeat was inevitable.
* LoopholeAbuse: Given ORT's RealityWarper nature, both Chaldea and the audience are led to believe that this is the real ORT of Proper Human History and a Lostbelt version can't exist, since its quasi-Reality Marble would override the Lostbelt. But the meeting with Ixquic reveals there is a way for there to be two [=ORTs=]: for the Lostbelt's PointOfDivergence to happen before the real ORT even landed on Earth. Fortunately for the planet, the PHH ORT stays asleep and out of the picture as Chaldea deals with the Lostbelt version.
* MagikarpPower: ORT's CannibalismSuperpower. It's stated by supplementary materials ORT has no weakness when the battleground is Earth, and this Lostbelt shows exactly how; in its fight against Lostbelt Camazotz, ORT was fighting in a barren prehistoric Earth with no human, Servant, other Gods or any lifeform which it could devour to gain an ability which can bypass a Beast's NighInvulnerability. This means fighting ORT in ''any'' other time period in which the Counter Force is active would ''massively backfire'', as Counter Guardians and Grand Servants summoned to fight it would only give it new abilities it otherwise wouldn't have. Sure enough, after it has consumed enough Servants in the raid against it, it has learned enough about Heroic Spirit Summoning to turn it against you.
* MarathonBoss: The most extreme case in the game. When you finally get to fight it properly, it has 10 break bars of 1.000.000 HP each (which the game encourages you to [[DuelBoss solo]] by the way, as you're trying to use as few servants as possible), then you are treated to five break bars of 1.200.000 HP each, and after that a single break bar of 2.000.000 HP. If you clear all that without losing all your servants before clearing this last bit, then you get a proper party boss fight with 3.000.000 HP. And after THAT, you have to fight ORT-Xibalba (aka this thing reviving itself from the dead), which has 6 break bars with 1.600.000 HP total, and deliberately slows you down by doing stuff like preventing you from using Arts Cards or forcing you to clear the last Break Bar with a solo. It is, bar none, the longest main story fight yet, by a long, LOOOONG shot.
* MistakenIdentity: It was initially confused for Type-Mercury, but was later revealed to be the Ultimate One of the Oort Cloud. Of course, this raises questions as to where is the ''real'' Type-Mercury.
* NamedAfterTheirPlanet: Unlike its sibling Type Venus, its name is almost identical to its homeworld.
* NighInvulnerability: The few known things in the whole franchise which can meaningfully hurt ORT (the other Ultimate Ones, the real Black Barrel[[note]]which is not guaranteed to kill a Type and if it did the death may not be permanent while our own [[https://reddit.com/r/grandorder/comments/10pzrbb/lostbelt_7_golden_sea_of_trees_travelogue_nahui/ja1mguo/?context=3 Black Barrel Replica cannot work because it lacks a concept of death]][[/note]], and Ado Edem[[note]]who does not exist in any capacity outside one [[BadFuture possible future]] and is noted to severely damage the planet whenever he uses Slash Emperor[[/note]]) are absent in ''FGO''. Chaldea has no way of knowing this, and thus are caught by surprise when nothing they can do deals any damage, and even the [[WorfHadTheFlu admittedly-weakened]] ''Foreign God'' who fires a black hole still does jack-squat against it. It's subsequently revealed Lostbelt ORT has been weakened due to the loss of its heart, and they do have the one thing which ''might'' do lasting damage to it -- the Hume-Barrel Rayproof -- which is ''still'' potentially a crapshoot since it's a weapon which exterminates threats to the planet whereas ORT was invited as Gaia's guest. Fortunately, while it remains unknown whether it would have worked on Proper Human History ORT, it ''does'' work on the Lostbelt ORT and it's enough to destroy its main body... [[StayingAlive though that still doesn't kill it]].
* NonMaliciousMonster: Despite being called here to exterminate humanity in the future, ''Angel Notes'' establishes the Ultimate Ones have no enmity towards humans. They're just following Gaia's wishes, and ORT's behaviour reflects that as it's content to ignore everything and just sleep unless someone's stupid enough to enter the Crystal Valley. Unfortunately, the circumstances behind the slumber of the Lostbelt ORT mean it's very pissed off and malicious, which means if it awakens under the conditions Daybit wants, a rampage that can lead to the planet's destruction is inevitable.
* NotSoInvincibleAfterAll: Make no mistake, its reputation as TheDreaded is ''more'' than earned, to the point where Chaldea has to pull out everything within ''and'' without their arsenal to bring it down. But for all of ORT's might, even an Ultimate One has flaws:
** Before consuming and analyzing enough beings to [[CannibalismSuperpower develop it]], ORT doesn't have the capacity for critical thinking. With Camazotz as the sole (and unkillable) remaining human left on the planet, ORT could've simply left the Beast to mope, but still fruitlessly tried to kill him despite having no answer for his immortality. And because its removed heart is still intact, despite being able to [[FromASingleCell regenerate a new one]], ORT instinctively tries to reclaim the old one because it still physically exists. ORT wouldn't even have realized it could simply ''go around'' the obstructing Tenochtitlan's HumongousMecha if it hadn't consumed Servants on the way. This ends up buying Chaldea valuable time.
** ORT isn't able to crystallize and consume things that don't have a concept of death. Such beings are few and far between, but they ''do'' exist, and the immortal Camazotz was unfortunately one of them. In Proper Human History, ORT would have a smorgasbord of ways to impose a concept of death on beings that don't have it, but in the Lostbelt where all sentient life was extinct except for the rampaging Camazotz, ORT simply has nothing in its arsenal for true immortals. It's DavidVersusGoliath taken to the extreme, but so long as the immortal doesn't stop, ORT ''will'' fall in time.
* ObviousRulePatch:
** ORT is only able to absorb Servants that it defeats. To prevent players from using sacrifice effects such as Arash or Chen Gong's Noble Phantasms to cheat it out of a kill, every Servant is 'buffed' with a permanent passive Guts that only activates from sacrifice effects.
** To prevent stall tactics, ORT inflicts the more traditional debuff of MaximumHPReduction on the whole party and worsens it every turn. This, along with the massive damage boost it gets from one of its Break Bars depleting, ensures that the player ''must'' send out new Servant(s) for every bar.
** Rather than being turned into crystal and absorbed, Mash retreats from the fight like usual. Because this means she doesn't suffer from the normal DATA LOST penalty every other Servant that dies to ORT is saddled with, she instead is prohibited from entering the next few fights.
** In a more benevolent example, unlike other feature fights where the player must deploy at least three Servants, the ORT raid lets them deploy one at a time so as not to put a heavy constraint on their barracks.
* OlderIsBetter: Its Grand Foreigner form gleefully exploits the Nasuverse's "The older something is, the more powerful" rule. Thanks to the Fantasy Tree it absorbed it can create a virtual history for itself to feed into the Throne of Heroes, and thus on the first reading, it makes ''a 300 million-year-old history'' of itself, making it one of the oldest Servants. By the time it was finally killed, it comes back ''again'' as a "Star Cell" and was going up to '''14.6 billion years old''', making it ''older than the universe''. Thankfully, Chaldea is spared fighting this form, as Kukulkan kills herself and takes the Ultimate One entity with it. Who knows how ''powerful'' and what abilities it could potentially have by making itself '''that old'''...
* OneManArmy: Canonically, Chaldea throws ''every Servant they know of who could logically be sent'' (read: anyone who was not totally erased from existence, such as Solomon and Musashi) against ORT as it makes its trek through Mictlan. [[NighInvulnerability This doesn't really do much more than slow down its advance]], until its body is destroyed from the Hume-Barrel Rayproof. The Servants do have a better chance against its Grand Foreigner Servant incarnation, but killing that just prompts it to summon another.
* OrganicTechnology: For all that ORT appears to be and behaves like a machine, to the point its awakening is portrayed visually and audibly more like a robot starting up after disuse than a creature rousing from slumber, it is most definitely an organic being. Yet another entry on the list of how ''alien'' this thing is.
* OutsideContextProblem: Unfathomably powerful as ORT undoubtedly is, considering it's explicitly the most physically powerful being in the franchise at least up to October 2014 and the "biggest fish" of its own personal pond by virtue of being the Oort Cloud's UltimateLifeForm, it's just one out of at least eight or nine other Ultimate Ones alluded to in Angel Notes. However, Complete Material suggests it's among not the Ultimate Ones who received Earth's SOS call there! What makes ORT such an anomaly is that it inexplicably chose to arrive on Earth thousands (or in the Lostbelt tens of millions) of years before it was supposed to and, as a result, humanity is nowhere ''near'' ready to handle something with its kind of power.
* PlanetEater: ORT not only has the power to [[PlanetDestroyer blow up planets]], but snack on them too. Multiple characters refer to it as a planet-eating monster.
* PowerfulButIncompetent: Its biggest weakness is that for all its ridiculous array of powers, it doesn't have the intelligence to use them effectively. ORT could easily have regenerated a new heart after Camazotz tore its first one out, but its instinct is to prioritize taking it back over regeneration so long as the heart still physically exists elsewhere. This buys the Lostbelt every precious bit of time they need to defeat it as ORT takes the long way to Mictlan's sun.
* ReadingsAreOffTheScale: The difficulty level for every fight with it is EX. Not 90+ or even 90++, just EX. That's how scary ORT is.
* RealityWarper: Strictly speaking, the Crystal Valley is less turning the ground to crystal and more warping the Texture (the "cosmos" as the Planet perceives it, enforcing the Planet's laws) around it to resemble its home world: it has been compared to Reality Marbles, except on a much higher scale and so powerful that even the World cannot reassert its natural order. It uses this ability upon awakening, turning the Lostbelt into a literal sea of Trees of Emptiness thanks to consuming the original Tree long ago and gaining the ability to replicate its functions. This is shown when after taking over the Lostbelt, the icon for the Seventh Lostbelt in the main menu glitches out before reforming into its world, titled "ORT Xibalba". And this was at ''low'' power -- if ORT had its heart, the entire Lostbelt and everything in it would've been crystallized instantaneously.
* SelfInsertFic: InUniverse. As a last-ditch effort to survive, ORT uses the Tree of Emptiness it consumed to quite literally invent a timeline where it was revered as a "hero" in order to create a Servant version of itself, which was inserted into the Throne of Heroes and then summoned to fight Chaldea. Since this history is completely fictional, ORT ''starts'' with a version that predates humanity by a ''long'' shot and then tries to summon a version of itself ''older than the universe'' after that.
* SealedEvilInACan: Unlike the ORT of Proper Human History who went to sleep peacefully, this ORT had its heart stolen away by Camazotz and was put to sleep in the very bottom of Mictlan, nigh-impossible to reach even for a Deino. It's understandably cranky once Daybit reawakens it and proceeds to rampage across the Lostbelt as it heads for its missing core -- Mictlan's Sun, Kukulkan.
* ShapeshifterDefaultForm: Despite its lower body being a mutable projection generated by its ''real'' body the [=UFO=], its preferred projection is an eight-limbed spider with a distinctive head. The head also appears on its UFO body, showing where it's facing right now. Even when it has to adopt a more humanoid form as Grand Foreigner, it still has the same head along with appendages and limbs resembling its eight spider legs.
* SleepModeSize: ORT's initial form is a fair bit smaller than its primary one, and is nothing more than the creature being in a literal sleep mode that defends itself. Defeating this form doesn't kill ORT -- it just ''wakes it up on the wrong side of the bed''.
* StayingAlive: Even next to monsters like Tiamat, this thing's inability to die is ''absurd'', and both Chaldea and the inhabitants of the Lostbelt had to pull out damn near everything to finally take it down.
** For starters, as one might expect from Ultimate Ones, it has no concept of death -- meaning dying simply isn't part of the script of its existence, thus RealityWarper effects which would normally result in instant deaths just don't work on it.
** Ereshkigal Alter summons [[GiantFootOfStomping one thousand Gugalanna legs]] ''en masse'' to crush the rampaging spider in an attempt to keep it from moving forward. She fights so hard that Dumuzid says she could have even repelled ''Sefar'' and destroys it. It turns out the spider is not its real body, the UFO hovering over it is; it simply autotomizes the spider body and keeps flying, and later regenerates the spider body anyway.
** Beni Enma Alter manages to enforce a concept of death onto it. It turns out it can regenerate FromASingleCell, so deaths of its individual cells don't really slow it down. Even when it turns out Tepeu has been sitting on [[ShatterpointTap Mystic Eyes of Death Perception]], not even ''that'' can outpace its regeneration. Eventually ORT throws even that off and regenerates itself with a brand new concept once it realizes its in actual danger.
** It gets the Hume-Barrel Rayproof, Chaldea's Excalibur cannon, fired straight at it since it's a Threat to Humanity. The UFO just ''bends space'' to deflect it.
** When U-Olga Marie finally manages to speed up Chaldea's time so they can destroy it with the Hume-Barrel Rayproof, it uses the accumulated data about Heroic Spirit Summoning from the Servants it ate to essentially hijack the Throne of Heroes, ''outright creates the seat of Grand Foreigner,'' '''''and puts itself on said seat to summon itself'''''. It's essentially the same trick Gilgamesh pulled in the Babylonia Singularity on an even crazier scale.
** Even after defeating Grand Foreigner ORT, ''another'' one gets summoned right after that's ''even stronger'' than the last one, and trend that will continue as long as even one piece of its original body remains in the world -- said piece is currently being repurposed as Mictlan's sun. Kukulkan, the avatar of that deified sun, [[TakingYouWithMe commands it to self-destruct in a glorious explosion that consumes the Grand Foreigner along with every Fantasy Tree it spawned]], finally defeating the alien monster for good.
** And even ''this'' may not have killed it. It wouldn't be the first time a Type has survived true death in the series, such as Type Moon persisting as a ghost. Only the Cosmos Denial erasing the very world it hijacked ensures it is KilledOffForReal, and even then, the mark it left on the Throne of Heroes remains...
* StoryBreakerPower:''Yep.'' '''Absolutely.''' It is stated throughout the franchise and shown in this game that ORT would absolutely kill damn near everything thrown at it if it was fought under ordinary circumstances. The Lostbelt was essentially picked by Daybit to create conditions where beating ORT becomes remotely possible, and many major events in its history revolve solely around ''nerfing'' ORT somehow and preventing it from simply regenerating its heart. Daybit's scheming, and essentially the Lostbelt's story, outright wouldn't be possible otherwise.
* SuspiciouslySimilarSubstitute: ORT's role in the seventh Lostbelt is basically filling the role of Tiamat from the Babylonia chapter, as a [[NighInvulnerability Nigh Invulnerable]] being who spends the first part of the story asleep, but once they awaken, continually chases down the heroes despite everything being thrown their way. This is further made clear by the presence of characters like Ereshkigal Alter.
* TakenForGranite: One of its powers is to transform anything into crystal, from anyone stupid enough to attack it to the very Earth it stands on. This transformation can be delayed, as Astea manages to last long enough to return to the Clock Tower before crystallizing. It is also self-sustaining, as seen on the chapter map where areas that have been converted into crystal keep growing in size even after ORT has long since left the area.
* TakesOneToKillOne: ORT's original body is only destroyed with the full power of its sibling Gaia fired through the Hume-Barrel Rayproof, followed by its own heart self-destructing to destroy its entire existence completely.
* UltimateLifeForm: As a TYPE/Ultimate One, it is explicitly the most powerful/perfected existence of its home world, with strength easily surpassing most of the Divinities of the setting, including the {{Top God}}s. It's telling that the Foreign God (a ''Beast'') intending to try and pull a GrandTheftMe on it is treated as HijackingCthulhu. The chapter shows exactly why it is an Ultimate One as it adapts to everything the Lostbelt throws at its way, to the point even ''death'' is a minor speed bump for it.
* TheUnfought: Its final form, the Starcell, ultimately isn't fought in gameplay. Due to Chaldea already running on fumes [[MarathonBoss from fighting several of ORT's forms and the Grand Foreigner at this point]], it's ultimately defeated by Kukulkan's Noble Phantasm before it has the chance to fight.
* UnseenNoMore: It ousts Fou as the character with the longest time between their first mention to their first proper appearance, a whopping ''22'' years. It's been hyped up as an indestructible, planet-consuming monster for all that time, and even this alternate version of ORT didn't disappoint.
* UnstoppableForceMeetsImmovableObject: Once Camazotz became an immortal Beast, he fought ORT against in a never-ending battle with neither having the power to truly kill the other. Nasu clarified in the F/GO 8th annivesary interview for Famitsu that when Camazotz tore out ORT's heart, ORT had vaporized all of Camazotz but his right arm as a counter-attack. Had Malla not intervened and put ORT into slumber with its trick signal, the two would have regenerated themselves and kept on fighting endlessly.
* VillainOverride: It attempts one on Kukulkan even before it wakes. She fortunately has the will to resist it.
* WeakButSkilled: Lostbelt ORT is this in comparison to itself from Proper Human History, at least by the time it is finally defeated. Strictly speaking, its original self has superior stats due to possessing its heart, and having interacted with enough beings that it has a massive amount of power assimilated. Lostbelt ORT however, due to its exotic diet of Servants and a whole Tree of Emptiness, can not only call upon the abilities of whatever Servant it devours but is also able to figure out how to perform Heroic Spirit Summoning, and thanks to the powers of the Tree of Emptiness is able to personally uphold its own timeline and even simulate new ones to create custom Servant versions of itself for it to use its newfound summoning ability on. Even its ability to transform the landscape to suit it goes from just recreating its homeland to being able to make new Trees of Emptiness, which is arguably more disastrous for the mess all those Trees would make if they reached maturity.
* WorfHadTheFlu: Due to missing its heart, Sion states this ORT is still not as powerful a threat as the one still slumbering in Proper Human History. The battle against it is a race to defeat it before it can get its heart back, but as it turns out even weakened it is still ultimately beyond Chaldea and the Lostbelt's ability to handle, requiring the VillainsDyingGrace of the Foreign God ''and'' the HeroicSacrifice of the Lostbelt King (ORT's own heart) to kill it at last.
* WorldsStrongestMan: It's been hyped up as the strongest being in the Nasuverse, a humanity killer to rival Primate Murder, and has more than enough power to destroy the planet with likely only a middling amount of effort. According to Sion, if Chaldea is Level 50 and the Foreign God (who is explicitly a PlanetDestroyer with her black hole generation feats) is 1000, then ORT is an astonishing ''10,000''. In fact, ORT is ''so'' strong that a mere fragment of it summoned is considered to be a ''Grand Servant'', putting it on a level comparable to Solomon, Super Orion, and Romulus-Quirinus, though perhaps it is more appropriate to say ORT is to these servants what the Grand Servants are to ''everyone else''.
* YouCantFightFate: ORT's awakening is inevitable. Camazotz ripping out and separating it from its heart might have forced it to shut down, but it would have eventually regenerated a new one and awakened. Malla exerting her influence to fool the sleeping Ultimate One could only slow the process down to a passage of ''millions'' of years, but it would still wake eventually. Under normal circumstances ORT awakening would just result in it going on a small rampage and trashing some of the planet before taking off back into outer space, but Daybit and Tezcatlipoca's plan amounts to jump-starting ORT with a new heart filled with the resolve to destroy the planet, which would influence ORT to carry out the goal of destroying CHALDEAS.
* YouDontLookLikeYou: ORT's [[https://static.wikia.nocookie.net/typemoon/images/e/ed/ORT.png/revision/latest?cb=20140703150351 initial appearance]] in Tsukihime's ''Character Material'' differs in several notable aspects; [[https://static.wikia.nocookie.net/typemoon/images/f/fa/ORTTransparent.png/revision/latest?cb=20230206170557 its original palette of green flame has been discarded in favor of blue, the halo has been shifted from behind to above its head, and its silvery-gold armor has been made entirely black.]] This discrepancy is answered by the simple reveal that [=ORT's=] "body" is just a mutable projection from its [[https://static.wikia.nocookie.net/typemoon/images/0/00/GalacticaSupercellTransparent.png/revision/latest?cb=20230304130346 halo/UFO true body]], which itself can also change shape on its whim. This ORT is also native to the Lostbelt, not the one from Proper Human History, and is also missing its heart, which might also explain the differences. Interestingly, both incarnations of ORT summoned as Servants return to the green-flamed golden-armored aesthetic.

* DegradedBoss: During the ''Serva Fes 2023 Servant Summer Festival'' event, Cernunnos' overwhelming boss abilities (and hit points) have been split evenly among the three versions of him encountered during it. Moenunnos has his DamageOverTime stacks (albeit with Burn instead of Curse), Uminunnos has his StoneWall charge swap manipulation gimmick (again, with Storm Layers instead of Curses), and Yamenunnos has Baobhan's borrowed Skill and NP Seal capabilities but with the NP drain tied to his own NP instead of a Skill. However, each one has a nasty additional trick on top of these. Moenunnos can cast Spreading Fire, and does bonus damage against enemies afflicted with Burn. Servants that attack Umununnos to remove his Storm Layers have their health drained and their defense decreased. Yamenunnos has a high chance of automatically stunning a Servant when they activate their skills, his seals combo with how he has increased defense against debuffed enemies, and he cleanses the three latest buffs of his opponents every two turns.

--> ''Narration'': The end arrived without mercy. The end arrived without cause. No longer does refuge exist in the underground world. The Fantasy Tree seeds came in droves, ravenously consuming all vegetation as nutrients. They considered all non-plant life as enemies, and attacked them indiscriminately. The animals killed by the seeds were crystalized, and then shattered to become stardust scattering in the winds of Mictlan. Deinos and Ocelomeh alike, all who lived in the forest dwellings lost their lives, powerless to resist.

* FastKillingRadiation: Its body expels so much cosmic radiation that just getting near it is fatal, even for Servants and Deinos. The protagonist requires a makeshift spacesuit given by Daybit just to survive its vicinity. This is reflected in its raid battle where all Servants are given a gradually-worsening MaximumHPReduction.

** ORT's second theme, "[[https://youtu.be/gq9v_qvk3xg Invade Spider]]" is a much harsher and faster arrangement of the first, as Chaldea has to contend with the fact it's legitimately woken up and it's ''pissed''. ORT is then chasing its heart down as Chaldea desperately tries to stop it and slow it down, to little avail. The theme plays one more time when ORT regenerates its spider form on its final health bar, at ''3,000,000'' HP, as the heroes take the battle to near outer space and it grows to roughly '''Cernunnos''' size.

-->'''Dumuzid''': Ereshkigal, you did well.... You fought so hard you became one with Kur...no, it would be no exaggeration to say that you were fighting as Kur itself. You would have even repelled the vanguard of a civilization-reaping planet. But this time it was just a bad match up. Truth be told, that thing eats planets. It couldn't have been defeated by anything from Earth

* AntagonistTitle: After ORT awakens in full, the title of Lostbelt 7 changes from Golden Sea of Trees Travelogue, Nahui Mictlān, to Forest of Emptiness Travelogue, ORT Xibalba, as it terraforms the entire Lostbelt into its Crystal Valley.

* {{Determinator}}: '''''Holy Flipping Hell Yes'''''. While most of ORT's actions are instinctual or a case of JustFollowingOrders (specifically to fulfill GAIA's request to destroy mankind), the final portion of Lostbelt #7 sees ORT pulling out all stops and straight up doing the impossible ''purely out of the desire to defeat the protagonist''. This includes ''hijacking the Throne of Heroes'' '''so it can summon itself into battle''' '''''as the Grand Foreigner'''''.

* OlderIsBetter: Its Grand Foreigner form gleefully exploits the Nasuverse's "The older something is, the more powerful" rule. Thanks to the Fantasy Tree it absorbed it can create a virtual history for itself to feed into the Throne of Heroes, and thus on the first reading, it makes ''a 300 million-year-old history'' of itself, making it one of the oldest Servants. By the time it was finally killed, it was going up to 14.6 billion years old, making it ''older than the universe''.
