Fanfic / Imaginary Seas

Percy Jackson isn't quite sure what's happening when he woke up on the shores of a sea he didn't recognize. All he knew is that he's a Servant summoned by the World to save it after things went to hell. No map, no teammates, and no direction save "Find the others who have been summoned and save the world before you all die."

In other words, just another quest in his life as a demigod.

But things get stranger when he realizes that this Lostbelt he's been summoned to is not like the Ancient Greece he dealt with in life. The Greek gods are enormous alien robots. The Earth has been blown up for the second time. Perhaps, most perplexing of all, his father outfitted him in armor with a Cleavage Window.

Percy has seen a lot as the son of Poseidon, but going against Olympus itself might be the craziest thing he's done yet.

Imaginary Seas is a The Camp Half-Blood Series/Fate/Grand Order crossover written by Ryuugi. It follows Percy's journey through the Atlantis Lostbelt prior to the arrival of Chaldea, as well as the ripples his presence causes.

The story assumes that you're already familiar with both the events of both the Camp Half-Blood series and the Atlantis and Olympus chapters of Fate/Grand Order. All spoilers pertaining to both series are unmarked. You Have Been Warned.

After a long period of hiatus, it updated on 7/18/2021.

Imaginary Seas includes examples of:

A to M

• The Ace: Percy is a tremendously powerful Servant with amazing stats, a laundry list of skills, and a Hyperspace Arsenal of Noble Phantasms. He utterly thrashes both Caenis and Lostbelt Chiron, who both threatened to wipe out Chaldea in the original game, even while holding back to avoid the wrath of the gods. That said, he has to be this, lest he be slaughtered like so many other Servants summoned to fight in the Lostbelt.
• Achilles' Heel: Since Percy possesses the Curse of Achilles, he has one on his back opposite his navel. But since it was never struck in life, Percy's version of Andreia Amarantos doesn't weaken him when he's struck there besides permanently turning off the Noble Phantasm.
• Action Pet: As a Rider, Percy is able to call upon the mounts he used in life. So far, he's only used Mrs. O'Leary's aid to Shadow Travel between islands. And while she's a hellhound the size of a tank who is more than capable of taking care of herself, Percy would much rather keep her hidden and safe because of the danger the Lostbelt Servants pose as well as how necessary she is to escape the wrath of Artemis and Zeus.
• All for Nothing: Percy does his best to minimize civilian collateral during his battles, but he soon finds that it's all for naught, as succeeding in his quest will destroy the Lostbelt and wipe everyone in it from existence. Despite this, he stubbornly sticks to his morals until Olympus' forces rally the populace against him, forcing him to reluctantly destroy everything on Eris Island with Nine Lives to obscure his and Chiron's escape from Artemis' and Zeus' prying eyes.
• Alternate Self:
  • The Chiron that appears in the story is the one that appears in Fate rather than the Chiron who taught Percy almost everything he knows. Despite this, Chiron possesses all of his counterpart's memories of Percy and greets him warmly on sight due to being from the Throne and having access to information on Percy's legend. On the same note, the Lostbelt version of Chiron appears to try to absorb the Pan-Human Chiron to gain his knowledge.
  • The gods also differ drastically from how they're remembered in Pan-Human History. Having never lost their Aletheia, their Humongous Mecha bodies, they were never weakened and thus upgraded into their godly machine forms seen in the Lostbelt. They also operate on cold logic, having never mingled with humans enough to truly relate to them.
  • The author has also discussed what Percy would be like under other classes, as he qualifies for all of them through his exploits. These different versions of Percy would be summoned from different points in his life, such as his Berserker version resembling how he was shortly after the end of The Last Olympian, while his Caster version would be him in his 40s after he's grown up and had kids. The Rider Percy seen in the story depicts him as being in his early 20s, after the Second Gigantomachia but still at his physical and mental peak.
• Always Accurate Attack: Chiron's Noble Phantasm, Antares Snipe, acts as this. Akin to Zoe's arrows, the constellation Sagittarius fires a "comet shot" on Chiron's command with tracking abilities to always strike its target. While it's lacking in destructive power, its unerring accuracy makes it a valuable tactical asset, such as when he uses it to paralyze his Lostbelt counterpart.
• Always Someone Better:
  • In Fate/Grand Order proper, Caenis is a Divine Spirit to be feared and is only beaten through gratuitous Loophole Abuse from Orion aka Grand Archer and Jason. Unfortunately for her in this story, Percy has everything she has but better, on top of martial skill honed from not being invulnerable. It's little wonder that he easily defeats her once he gets serious, not to mention being able to simply pray away the blessings his father gave her. He does admit the slim possibility she could do the same thing to him, but Caenis is both too prideful and hates Poseidon too much to ever try.
  • Percy is an incredibly powerful servant because of how much he accomplished in life, but he's well-aware that even at the peak of his power, he's no match for his father Poseidon in a straight fight, especially since Lostbelt Poseidon has his Aletheia, making him even stronger than Percy remembers him.
  • As powerful as Zoe and her edition of Nine Lives are, it's essentially a single Astromancy spell on the level of a Noble Phantasm. Wodime's mastery of the Animusphere's Astromancy magecraft is far more complex and powerful. While Percy and Zoe can create a single pseudo-circuit with their power in the ideal conditions of the Atlantic Lostbelt, Wodime can rearrange the entire sky to put out power that can bring the gods to their knees.
• Annoying Arrows:
  • Due to Percy's invulnerability on the sea, Lostbelt Chiron's arrows ping harmlessly off his skin. Chiron exploits this to signal Percy by shooting an arrow at back of Percy's head to discreetly get his attention. Percy goes on to ask why anyone would send a message via arrow to the head.
  • Fully averted by Zoe and Artemis, whose "arrows" come down as deadly lasers. Zoe's lasers are powerful enough to burn a hole in people's heads on the lowest setting and scour a small island on their highest. Artemis' laser is an Anti-Planet Noble Phantasm, making it powerful enough to obliterate pretty much anything other than another Noble Phantasm of incredible power and renown.
• Anti-Magic: Percy has a listed Magic Resistance of C, only allowing it to block weak spells with two verses or less. But his effective rank is significantly higher due to saving Hecate from being bound in eternal torment for rebelling against Olympus and granting her recognition and a cabin at Camp Half-Blood. It gets bumped up to A while he's standing in water, and elevated to EX after taking Moly.
• The Archmage: Wodime's Astromancy magecraft is so powerful in the Atlantic Lostbelt that he can easily dominate Servants in single combat and even kill gods. This is how he brought Caenis under his fold and threatens to do the same to Percy should he not retreat.
• Ascended Extra: In the story, not only Chiron is not killed by his Lostbelt counterpart, but he even manages to absorb him, gaining the power and knowledge of Lostbelt Chiron.
• Attention Deficit... Ooh, Shiny!: Percy's magical ADHD acts up when Lostbelt Chiron's forces don't rush him as he'd expected them to while Percy is trying to create a distraction. He has to occupy himself with meaningless tasks like cleaning Riptide and counting all the people in his family tree to keep himself from going against Pan-Human Chiron's plan.
• Audience Surrogate: Zigzagged. Percy is an Experienced Protagonist who has saved the world time and again and lived through Greek myth in the modern day, but he's also completely unaware of the gods' secret history as machines from another world or the notions of Servants or Lostbelts. Because of this, numerous pieces of information are introduced to the reader by others telling it to him.
• Awesome, but Impractical: It's noted that while Percy is a ludicrously strong Servant, his strength and arsenal of skills and Noble Phantasms make his upkeep absolutely ruinous. Because of this, he'd be virtually impossible to utilize in a Holy Grail War without the aid of an external power source. The only reason he's able to operate at all is the fact that the Lostbelt is rich with mana due to the Age of Gods never ending on top of being supercharged with the Klironomia of several Greek gods to compensate for his energy costs. If he hadn't gotten those nanomachines, he would have faded away before he even finished his first fight. Percy speculates that his outrageous mana costs are the reason why he wasn't summoned to save the world when human history was incinerated by Goetia, and he is only summoned into the Atlantic Lostbelt because it is the only place he'd actually have a chance of lasting long enough to fight.
• Awesome by Analysis: Both Chirons are capable of this. Lostbelt Chiron smugly points out the delay between Percy's swing the lasers coming down from the sky, alternating his rate of fire to in an attempt to overcome Percy's defenses. Pan-Human Chiron runs a Batman Gambit based on what he knows about himself and the gods of the Lostbelt to keep Artemis from simply nuking the island.
• Badass Boast: Wodime says with complete and utter confidence that he alone would be enough to fight and kill Percy. This strikes Percy as arrogant, but he doesn't call Wodime out on it either. Given that Wodime's command of Animusphere magecraft grants him power comparable to Lostbelt Zeus, Wodime isn't bluffing.
• Badass Teacher: Chiron isn't just a teacher, but a master of every form of Greek warfare. While he's not as skilled as his students in any particular field (i.e. Heracles' Pankration specialty or Achilles' godspeed), Chiron is good at everything, going from brutally killing his foes with Pankration to firing his bow like a machine gun to strategizing against his more powerful and immortal Evil Counterpart without missing a beat.
• Bare-Fisted Monk: Percy finds Chiron fending off a small army with Pankration instead of his bow, beating thirty of them into a Klironomia-induced coma with his bare hands.
• Beam Spam: In comparison to Artemis' single devastating Anti-Planet beam, Zoe's lasers aren't as destructive but come down far more numerously and far faster, crisscrossing the area in front of Percy's sword swings with much shorter delays between shots.
• Berserk Button:
  • For Percy, it's insulting his mother. He kicks Caenis due to calling him "son of a bitch".
  • Chiron has almost the same button, only it's his students. He becomes murderous when his Lostbelt counterpart calls Percy "a waste of time."
  • As usual, for Caenis, it is Poseidon and anything to do with him. Before Percy learns her identity, when he notices she has similar abilities, he asks if she is one of his half-sisters, causing her to go even more berserk at the thought of being related to Poseidon.
• Bling of War: Percy finds himself outfitted in his father's golden armor upon being summoned in the Lostbelt. He's embarrassed by how gaudy it looks, not to mention the boob window.
• Born Lucky: Percy has an A Rank in luck, reflecting how prophecies always tended to go right for him even when the worst seemed inevitable It's also the same luck rank as the original Perseus he's named after.
• Brain Bleach: Percy's reaction to realizing that cannibalism is a recurring thing in Greek mythology after Chiron says he plans on absorbing his Lostbelt counterpart for power and information.
  Percy: Cannibalism kind of ran in the family, anyway. —Oh gods. I didn’t need that thought. I did not need that thought.
• Brains and Brawn: Percy and Chiron form this duo. Percy is the Brawn, having been supercharged by the Klironomia he's been taking in as well as his wide array of Noble Phantasms and skills that make him a One-Man Army. Chiron is the brains, as he is still the wiser and more calculating of the two of them and has more knowledge of what exactly is going on in the Lostbelt.
• Broad Strokes: The author takes some liberties in order to bridge the two series together. Luke, for instance, is never burned by Hestia's fire or electricity from Hephaestus' chair in this story, as that begged the question of why Hestia or Zeus didn't simply smite him. Percy also has access to Nine Lives through the memories engraved in Riptide, which he gained after taking it back from Setne.
• Buried Alive: Discussed. After realizing that they were at an impasse due to their mutual Nigh-Invulnerability, Percy considers just burying Caenis alive under rocks and trees until she starves to death. He dismisses the thought when he remembers that Servants can simply disperse into Spirit Form.
• Cannibalism Superpower: Chiron notes that his Lostbelt version is trying to absorb him for the information he has on the Pan-Human Servants. Pan-Human Chiron decides to return the favor in order to gain an advantage.
• Cassandra Truth: When Percy finally meets Poseidon, just as Chiron warned, Poseidon doesn't recognize him and doesn't believe him when he says he is Poseidon's son. Percy has to show Poseidon his memories to convince him.
• Casual Danger Dialogue: In his usual fashion, Percy's dialogue is littered with quippy remarks while he's in the middle of fighting. Chiron is no slouch either, saying that he's having a "slightly difficult day" while he's busy murdering people with Pankration.
• Chainmail Bikini: Percy compares his father's armor more to a metal bra than a tank top, though he's grateful he at least has pants to go with the skirt armor.
• Classified Information: Due to being recognized as one of the Olympians, Percy's Servant stat sheet is redacted and abbreviated by the Interstellar Emigration Treaty that brought the gods to Earth. This conveniently serves as a Framing Device to slowly reveal Percy's capabilities over the course of the story, as more of the restrictions are lifted each time he breaks out new abilities in a fight.
• Cleavage Window: Percy is baffled by his father's armor, which has a gaping hole to expose his chest. It doesn't matter much given his invulnerability, but he feels indecent because of it and quickly looks for a shirt to cover himself up. After getting his armor upgraded by Hephaestus in time for his fight with Poseidon, Percy is dismayed to find that the window has gotten even bigger.
  Percy: Dad, why is there a boob window?
• Combat Parkour: Percy backflips over a crowd at one point and meets a soldier's charge only to jump and roll over his shield while tackling him to the ground.
• Combination Attack: Percy's version of Nine Lives has him ask for Zoe Nightshade's aid to rain hell upon his foes with a barrage of Kill Sat lasers. He makes a point of referring to his Nine Lives as "Nine Lives: Nightshade", to emphasize his gratefulness for Zoe's aid even though he can invoke it simply by saying "Nine Lives". He also refers to the resulting beams as "our light".
• Composite Character: An interesting case. The Chiron summoned by the World is Fate!Chiron with the addition of the memory of PJO!Chiron.
• Conspicuous Trenchcoat: Discussed and lampshaded. Percy puts on the Nemean Lion's pelt in the form of the trenchcoat he wore as a teenager while snooping around Deimos Island in search of Hephaestus. While the protection is obviously welcome, it makes him look suspicious and feel suspicious, to the point that he thinks people would call the cops on him if he put on a pair of sunglasses.
• Cool Sword: Riptide, aka Anaklusmos, has gotten even cooler after Percy became a Servant. In addition to all of its previous abilities (i.e. being anathema to monsters), its strength scales with the user's divinity, making it even more powerful due to Percy's possession of Poseidon's core. In addition, he's able to call upon Zoe's aid to assail his foes with Beam Spam from her constellation in the sky. Finally, he can unleash Heracles' Nine Lives by drawing on Riptide's connection to him and Zoe, allowing it to chop a replica of Cerberus to bits easily and even destroy everything on Eris Island.
• Cool Teacher: Chiron, as usual, is kind, noble, and an endless well of wisdom for his students. Percy instantly feels relieved to know that he has Chiron by his side. Chiron returns the sentiment, noting that even though Lostbelt Chiron has his immortality and more power, it was Pan-Human Chiron's decision to share his wisdom that brought Percy to his aid.
• Cool Uncle: While thinking about his family tree, Percy realizes that his beloved teacher Chiron, a son of Kronos, is technically his uncle. Percy doesn't dwell on it much though, as he is far more interested in whether or not Chiron is a robot like the Olympians.
• Curb-Stomp Battle: Percy's battle with Caenis is this to the point that he initially sums it up as "So anyway, I kicked her ass." When he decides to go into detail about their fight, he has the upper hand the entire time and can't even be scratched by her due to his invulnerability. He then simply prays her invincibility away before burying her in the dirt. The only reason why he doesn't kill her outright is the arrival of Wodime and the threat of Artemis nuking the island from orbit.
• Deadly Upgrade: Percy requests Hephaestus to make his version of Trident Ocean Ray as powerful as possible with full knowledge that it would certainly kill him by the time he's done with it. Since fighting his father would be a Suicide Mission regardless, he says that he might as well have every ounce of power he can to make it one with some chance of success.
• Deadpan Snarker: Percy still loves to snark at everything in sight, from his foes to the gods themselves.
  Minerva: Are you always this impertinent?
  Percy: Yes.
• Death of Personality: After taking his Lostbelt counterpart's memories, Chiron explains to Percy that Zeus completely wiped Poseidon's memory and reprogrammed him into a subservient attack dog that circles the entrance to Olympus to guard it from intruders. Because of this, reasoning with him would be useless, as he's essentially become an extension of Zeus' will. Despite this, Percy wants to try anyways, using the three favors Poseidon promised Theseus along with their bond as father and son in hopes of being able to start a conversation at the least.
• Deflector Shield: Hephaestus sends for Minerva to help him make the Aegis for Percy. Also known as the Divine Corpus Bounded Field, it is essentially the forcefield used by all of the gods back when they were ships. Making one for Percy would essentially give him the protection of a god, but against the likes of Poseidon, it would only even the odds enough that Percy would be able to withstand two or three non-fatal blows before it crumbles.
• Defiant to the End: Even when Percy proves to be Always Someone Better to Caenis and has her at his mercy, she refuses to surrender or beg for her life and instead keeps cursing him. Granted, it doesn't come to that since Wodime shows up for the save.
• Deity of Human Origin: Percy was born Semi-Divine, but is currently a full-fledged Divine Spirit due to being gifted Poseidon's Divine Core. While this bumps up his strength, it makes his mana consumption even more ridiculous and he needs several doses of Klironomia to be able to fight properly and it isn't until he takes in Athena's and Ares' Klironomia for him to be able to fight at full strength.
• Discard and Draw: In order to obtain armor and weaponry that will give him some chance of victory, Percy offers up several of the Noble Phantasms in his possession to Hephaestus. Among them, he hands over the Golden Fleece, Medusa's head, Riptide, his father's trident, his father's armor, the Nemean Lion's pelt, and Pandora's Box. With Athena's help, Hephaestus hopes to be able to recreate the Aegis, the Bounded Fields used by the gods when they were still ships, as well as overclock Percy's copy of his father's trident to go toe-to-toe with Poseidon even if it kills him.
• Does Not Know His Own Strength: Percy knows that he has new powers as a Servant that he never had when he was alive, but he doesn't know just how exceptional he is until Chiron shows shock at just how many Noble Phantasms he has, using five without thinking about it even while holding back. It's also played more conventionally when Percy suffers the effects of forcibly taking on Zeus' Klironomia. His body starts spasming so badly that when he tries to grip a tree for support, he ends up ripping it out of the ground and pulls it apart while trying to let go of it.
• Doppelgänger Gets Same Sentiment:
  • Percy hesitates when fighting Lostbelt Chiron, whose face reminds him so much of the Chiron who had taught Percy everything he knows. He gets over it with the knowledge that his beloved teacher from Pan-Human History is on his side. Even then, he's creeped out by the idea of Chiron more or less cannibalizing his Lostbelt counterpart and cringes when Lostbelt Chiron screams after being paralyzed.
  • When Percy learns that Zeus mind-wiped Poseidon into a mindless minion, he says he'll try to reason with him, believing their father-son bond plus Poseidon's three promises to Theseus will be able to reach him. Chiron points out that it won't work because they are in an alternate timeline where Percy never existed, so Poseidon wouldn't recognize him even if he wasn't mind-wiped. Percy says even so, Poseidon is his father and he has to try.
• Embarrassing but Empowering Outfit: Wearing your dad's Divine Armour is pretty awesome but all this gold is gaudy as heck and why in the name of everything holy is there a boob window?!
• Everyone Knows Morse: Percy uses Zoe's arrows to flash "five minutes" in Morse code as a discreet signal to Chiron. Justified in that Chiron could have easily taught this to his students as part of their training at Camp Half-Blood, even though he predates the concept by nearly 14,000 years.
• Evil Counterpart: Lostbelt Chiron is sadistic, had never taught a student before, and an enforcer for Zeus. He's about to hunt down the Pan-Human Chiron when Percy shows up to help drive him off. Lampshaded by Percy, who refers to Lostbelt Chiron as "Evil Chiron".
• Experienced Protagonist: Zigzagged. As a Servant, Percy has already lived through all of his adventures, married Annabeth, settled down and had kids. He comes across as Older and Wiser as a result and is at his physical and mental peak as a demigod warrior in both might and skill. But this is also his first time fighting as a Servant and encountering Nasuverse mechanics, which leaves him woefully out of depth regarding the metaphysics of his situation and the secret history of the Greek gods.
• Fantastically Indifferent: Subverted. Having saved the world time and time again, Percy thinks he's Seen It All until he learns that the Greek gods were giant robots. Then he starts getting regular doses of nanomachines to upgrade himself and learns about how the gods combined into a super mecha to fight off an Alien Invasion.
• Fatal Flaw: Percy is well-acquainted with the notions of this trope, and his own personal failing is his sheer loyalty: he'd doom the world to save a friend. So when someone close to him nicely asks for a favor, he can't turn them down, even when it goes against his personal feelings on the matter. He also exploits Athena's pride to get her to stop being obstinate with him and just give him more than just a map to get him to his goal.
• Fling a Light into the Future: Percy fully expects to die when he confronts his father, but hopes to be able to at least kill Poseidon to both free him from his servitude to Zeus as well as open the door to Olympus for the Servants that come after him. As if to emphasize the point, he hands Pandora's Box to Hephaestus, telling him to "just hand it to the next guy", in case he doesn't survive his battle with Poseidon.
• Force and Finesse: Percy's Noble Phantasms and raw strength makes him the force to Chiron's finesse. Percy is able to plow through most of his problems simply due to being far better equipped and more powerful, while Chiron's strategic expertise, wealth of knowledge, and general ability to see the larger picture makes him equally valuable even when he isn't slaughtering his foes with his bow or Pankration.
• Freudian Excuse Is No Excuse: When Percy learns who Caenis is, he is a little sympathetic to her because his father Poseidon had raped her, but he says that is no excuse for her threatening innocent people.
• Godzilla Threshold: Zeus combining with the Olympians into a super Megazord to defeat Sefar is seen as this. But the process is so uncomfortable and awful that the other Olympians that they were willing to die rather than do it, comparing it to a violation of their very selves. While they didn't need to do this in Pan-Human History, Lostbelt Zeus took the option out of their hands.
• Grand Theft Me: Chiron cannibalizes his Lostbelt counterpart and takes over his body, gaining his powers and memories in the process.
• The Great Offscreen War: Percy is astonished to learn of two wars that are never discussed in Greek mythology: the Leukosmachia 14,000 years ago when the Greek Gods fought Sefar, and the Olympiamachia, when the gods went to war with each other over their role in guiding humanity. Unlike Pan-Human History, Zeus forcibly merged with the other Olympians to defeat Sefar, which is why they still have their mecha bodies.
• Green Thumb: Lostbelt Chiron rallies the nearby townsfolk to use their Demeter Klironomia to create a cage of trees around Percy in an attempt to trap him.
• Half the Man He Used to Be:
  • In a demonstration of Riptide's sharpness, Percy cleaves through a tree trunk and one of Chiron's soldiers in one swipe.
  • Hephaestus was cut in two some point during or after the Olympiamachia, leaving parts of himself in both Atlantis and Olympus.
• Have We Met?: Percy has already met all of the Olympian gods in his own lifetime and treats them all like old acquaintances. By contrast, none of the gods had ever heard of him because he didn't exist in their history. Athena in particular, or rather her terminal Minerva, is baffled when Percy calls her his mother-in-law.
• Healing Factor: The denizens of the Atlantis Lostbelt have all been given Demeter's Klironomia, Ambrosia. As a result, they have the ability to regenerate from most wounds, only requiring a healing coma in the case of severe injuries, and are The Ageless.
• Heroes Love Dogs: Percy still adores his pet hellhound, Mrs. O'Leary, and takes special care to keep her out of danger. Mrs. O'Leary returns the favor by being endlessly loyal to him, taking his own well-being into account first and foremost.
• Heroes Prefer Swords: Percy still relies on Riptide as his main weapon of choice. It's been upgraded after his summoning as a Servant, scaling in power based on the user's Divinity and being able to unleash Nine Lives through its connection to Heracles and Zoe Nightshade.
• Hijacked Destiny: According to the author, Perseus Khresmos would work like this if Percy were to be summoned as a Saber. Instead of drawing upon his fate, he'd be able to become the focus of any fate or conclusion he would be eligible for because of his decision to become the focus of the Great Prophecy when he turned sixteen. So if one of twenty people were to be taken in for questioning, he could make it so that person would be him. This also means he can choose to take oh the fate of "Winner of the Holy Grail", meaning that in a Holy Grail War, he's guaranteed to win unless his opponent's luck stat allows them to outright defy fate.
• Historical Badass Upgrade: As a Rider, Percy has all of the Noble Phantasms and treasures he wielded in life, including several that he lost like the pelt of the Nemean Lion thanks to his Savior of Olympus skill. His Noble Phantasm, Poseidon Asphalios, also grants him access to every skill used by a descendant of Poseidon along with several Noble Phantasms due to his status as Poseidon's favorite, such as Orion's Stout Arm of Brutality and Poseidon's armor and trident. There's also the implication that he has the ability to transform into animals like Frank, but he decides not to bust it out to avoid drawing too much attention.
• Home Field Advantage:
  • Even more so than in life, Percy gets a massive power boost while in water. In addition to raising his overall fighting prowess, it bumps his Magic Resistance up to A, and he has an additional layer of Nigh-Invulnerability so long as he's near the sea.
  • However, in an inversion of this trope, Percy loses the Curse of Achilles in Rome or areas conceptually defined as Rome because of how the Little Tiber washed it away in The Son of Neptune.
• Hyperspace Arsenal: Perseus Khresmos is the embodiment of Percy's fate as a Greek demigod. He is able to draw upon it and his Savior of Olympus skill to access any and all of the Noble Phantasms he acquired and lost throughout his journeys. Having reenacted much of Greek mythology, Percy has a small armory of Noble Phantasms at his disposal, including several non-combative Noble Phantasms such as Moly and the Golden Fleece.
• I Can't Feel My Legs!: Chiron fires some arrows into the spine of his Lostbelt counterpart. Percy is unnerved by how Lostbelt Chiron's screams sound identical to the Chiron he knows, but the two quickly escape so Pan-Human Chiron can absorb him for power and information.
• I Gave My Word: Discussed and weaponized. Percy possesses one of Theseus' Noble Phantasms, the three favors he received from Poseidon that he promised to answer no matter what. Although Percy hopes to use these wishes to restore enough of Poseidon's personality to hold a conversation, Chiron advises him against that, as the gods repeatedly break their oaths and forgo their favors for their own convenience. Percy knows this but remains steadfast, as though oaths from Poseidon mean nothing to Chiron, as Poseidon's son, his oaths mean the world to Percy, just as Poseidon rushed to his aid during the Battle of Manhattan.
• Improbable Aiming Skills: Lostbelt Chiron is able to exploit the split-second delay between Percy's swing and Zoe's arrows to launch a barrage of arrows at him. Pan-Human Chiron manages to counter that barrage with a volley of his own in the same timeframe.
• In a Single Bound: Percy has the Mana Burst (Leap) skill to compensate for his lowered Agility rank as a Rider. He makes liberal use of it during his fight with Lostbelt Chiron's forces, leaping over 20 feet in the air to dodge attacks. It's noted to be especially potent when jumping between bodies of water, due to his feat of jumping from the St. Louis Arch to the Mississippi River on his very first quest.
• Indy Ploy:
  • While teaming up with Chiron to face off against Lostbelt Chiron, Pan-Human Chiron asks Percy to make a distraction so he can ambush Lostbelt Chiron from behind. He leaves the rest of the details up to Percy, who more or less shrugs and rolls with it.
    Percy: Do a thing so something happens and make it work out; sounded like a plan to me.
  • Hephaestus asks Percy if he has a real plan to defeat Poseidon. Percy admits that he only has vague ideas of what he's going to do when he inevitably clashes with Poseidon.
• Instant Expert: Discussed. Percy is baffled by how comfortable he is with Riptide's new laser function even though he never used it in life. Chiron explains this as a consequence of being summoned as a Servant, but the specifics of the metaphysics quickly bore Percy.
• Insufferable Genius: Athena is the goddess of tactical warfare and wisdom, but is especially proud and confident in herself, treating others like morons to be educated or chess pieces to move. Percy refers to her as a "heartless, cast-iron bitch", but is able to abuse her pride to manipulate her into being more helpful.
• Invincible Hero: Downplayed. Percy is borderline unstoppable in a one-on-one confrontation, between being invulnerable to most forms of harm, his incredible range of skills and Noble Phantasms, and just raw strength and experience from being the son of Poseidon, he's able to bulldoze the competition as a One-Man Army. His fight with Caenis is nothing less than a Curb-Stomp Battle and he's able to thrash Lostbelt Chiron after wading through his army of Elite Mooks. But Percy is aware that there's Always a Bigger Fish, and he knows he has no chance against the Olympians by himself, especially since they're even more powerful than he remembers them to be in the Lostbelt.
• Kill Sat:
  • Artemis resides in orbit to fire her Noble Phantasm, an Anti-Planet laser, upon anything deemed a threat to Olympus.
  • In a similar vein, Zoe Nightshade assists Percy through her constellation in the stars, raining arrows in the form of lasers upon foes in the general direction of Percy's sword swings through their mutual connection in Riptide. While these beams are normally a mere D-Rank Noble Phantasm, enough to injure but not kill a Servant, their power rises dramatically at night when the stars and moon are visible, easily delivering a Boom, Headshot! death to the soldiers Lostbelt Chiron sends after Percy. At full power, they're strong enough to scour an entire island.
• Laser-Guided Karma: Chiron's decision to share his knowledge with others and raise heroes in Pan-Human History is what brings Percy to his aid, something Chiron lampshades and is thoroughly grateful for compared to his sadistic Lostbelt counterpart.
• Last-Name Basis: Percy refers to Wodime by his surname, showing that he recognizes him as an enemy and not letting his morals get in the way in case he needs to throw down with him. Also because his first name, Kirchtaria, is hard for Percy to say.
• The Law of Diminishing Defensive Effort: Percy's invulnerability lets him shrug off nearly anything anyone can throw at him. But he makes a point of deflecting Lostbelt Chiron's arrows just in case they had a way to pierce them. When he decides to risk his shoulder to test them, he finds that his invulnerability on the sea still holds and completely abandons defense to go on the attack. That said, when Lostbelt Chiron's soldiers fill the sky with a Rain of Arrows, Percy dodges anyways as a precaution in case Moly didn't stop their magic from working.
• Leeroy Jenkins: Subverted. Percy expects Lostbelt Chiron's 400-or-so men to Zerg Rush him and try to overwhelm him with sheer numbers the way they had for Pan-Human Chiron earlier. Instead, they scurry about the island, making preparations to fight Percy. This ended up working in Percy's favor, as it gave Mrs. O'Leary time to rest and Chiron time to lay a trap.
• Lightning Bruiser: Percy is a modern-day Heracles in terms of strength, toughness, and agility. While his numerical parameters are currently unknown, he's incredibly strong owing to being a son of Poseidon and possessing a better version of Orion's Stout Arm of Brutality skill. He also has three different forms of Nigh-Invulnerability, can temporarily have EX-Rank Magic Resistance by using Moly, and can cross massive distances In a Single Bound with Mana Burst (Leap). This is on top of having top-notch combat training and reflexes from his high rank in Clairvoyance, his Eye of the Mind (False) skill, and generally being trained by Chiron himself.
• Making a Splash: As the son of Poseidon, Percy has the ability to manipulate water at will. So far, he's mostly used it for giving himself footholds and to outmanuever his foes, but he also has access to his father's Authority over the sea through his trident. Combined with his natural abilities, he should be capable of far greater feats, like the time he collapsed a glacier. Caenis also has access to the same Authority, using bursts of water pressure to send Percy flying.
• Master Swordsman: Percy's mastery of the sword is on full display here, as he utterly trounces Caenis once he gets serious and fends off a small army as well as Lostbelt Chiron on his lonesome through martial skill alone, only needing Moly to ward off magic attacks, his control over water for superior footholds, and Stout Arm of Brutality to wrestle Lostbelt Chiron to the ground.
• Mistaken Identity: Due to being Poseidon's son and having his armor, blessings, and Authority, others tend to mistake Percy for his father on sight. It tends to work in his favor, as most of Olympus' citizens rush to aid him on sight and the machines that responded to his father will also respond to him.
• Momma's Boy: Percy still thinks fondly of his mother Sally and doesn't take kindly to Caenis calling him a "son of a bitch", kicking Caenis across a beach in retaliation.
  Percy: [coldly] Hey, now. I’ll have you know my mother was a lovely woman. Everyone thinks so.
• More Dakka: Both Chirons are able to draw and fire their bows at speeds that make them act more like automatic weapons than bows.
• Morton's Fork: Percy tries to dodge the issue, but once Wodime confronts him about it, Percy realizes that acting will inevitably kill the countless people who lived in the Lostbelt, while not acting will inevitably kill the countless people who died when the Lostbelts were created. As someone who doesn't like killing people in general, this weighs heavily on him.

N to Z

• Nanomachines: The Greek gods are able to bestow a small fraction of their Authorities upon people they choose through special nanomachines called Klironomia, which are referred to as the legacies of the gods. Being implanted with them gives normal people the power to take on Demonic Beasts and even Servants, but the gods' special brand of Klironomia offers a much sharper boost in power and have special abilities. For instance, Demeter's Klironomia, Ambrosia, grants a powerful Healing Factor and eternal youth. Percy takes on several of these throughout the story to strengthen himself and manage his mana costs.
• Nice Guy:
  • Percy is a friendly and caring guy who doesn't want to see Olympus' citizens getting hurt even though he is summoned to destroy the Lostbelt and them along with it. Chiron is also a kind and noble teacher who Percy adores for being the kind of mentor figure he always needed as a kid.
  • Of the gods, Hephaestus is among the few who doesn't come off as a complete jerk, especially when compared to his ally Athena. In addition to siding with the Coexistence Faction, Hephaestus treats Percy respectfully and helpfully provides all the information he knows while pointing him towards Perse Island to get the Divine Construct he needs to battle Poseidon.
• Nigh-Invulnerability: Percy has three forms of invulnerability. Owning the pelt of the Nemean Lion grants him invulnerability to man-made weapons, he has the Curse of Achilles (aka Andreias Amarantos) rendering him immune to all non-divine attacks except for those that strike his weak point, and the blessing of his father in the form of Poseidon Asphalios, making him immune to damage so long as he's on the sea. Unfortunately for him, all of them are useless against the Greek gods.
• Non-Indicative Name: As per standard in the Fate series, Percy's Archer version wouldn't use bows at all due to how notoriously bad he is with them. Instead he'd simply use his demigod powers to fling water at his foes and shape it into weapons and attacks.
• No-Sell: Percy's multiple layers of Nigh-Invulnerability render most attacks meaningless against him. Lostbelt Chiron flings everything he has at Percy in hopes of taking him down: explosions, swords, arrows, magic, brute force, surprise attacks... but the worst they can do to him is knock him to the ground. A soldier who tries to choke Percy dangles uselessly off him. Even Lostbelt Chiron's attempts to cage him in with plant life are fruitless, as Percy easily plows through the cage with brute force. The invulnerability provided by his father proves especially important, as Percy notes that Lostbelt Chiron could have broken at least his jaw with his blows were he not immune to damage.
• Not Afraid to Die: Despite Chiron's pleas, Percy is resolute in his desire to confront Poseidon and potentially fight him to death with full knowledge that he will die in the attempt, as handling enough power to duel his father will inevitably kill him.
• Not in This for Your Revolution: While musing about the Morton's Fork of the situation he's in, Percy admits that he doesn't really care about whether Olympus stands or burns and honestly says that Luke's motives were understandable. He only fought for Olympus because countless people, including many that he cares about, would have been in grave danger if Kronos succeeded.
• Not So Invincible After All: Invoked. Percy is well aware that the gods are far more powerful than he is even with the Klironomia charging him and his arsenal of Noble Phantasms up. Because of this, he's always worried that the attacks thrown at him will have some way to bypass his invulnerability. This is why he fights as though he didn't have his invulnerability at all until he's absolutely sure that he's protected.
• Obnoxious In-Laws: Percy really isn't on good terms with his mother-in-law Athena whom he calls a heartless, cast-iron bitch and as such feels no remorse in trolling and manipulating her.
• Older and Wiser: The Percy who appears in this story is in his early 20s, having already lived through all the adventures described in Riordan's books. Because of this, he approaches most of his problems with a more mature and at times more cynical outlook than his teenage counterpart even though he remains as quippy and impudent as ever.
• Older Is Better: By Nasuverse tradition, older Mysteries tend to be able to overpower newer ones. As a result, the author says that even Percy's invulnerability would fail against the full might of Wodime's Astromancy magic, as while the Olympian gods are ancient, the stars have inspired wonder in humans long before the Olympians arrived.
• One-Man Army: Percy takes on 400 men on the level of Servants on his lonesome and wins without taking a scratch, not only because of his Nigh-Invulnerability, but also his raw combat prowess allowing him to overwhelm even Lostbelt Chiron. Lampshaded when Lostbelt Chiron uses the "we have you surrounded" line on him.
  Percy: Wow. He really didn’t even know me.
• Only the Chosen May Wield: Having been gifted his father's Divine Core, Percy is able to activate machines that would normally only be accessible to the Olympians or those working for them. He gets numerous doses of nanomachines this way. He's also been bestowed with the armor and trident of Poseidon, enhancing his already immense powers. His Savior of Olympus skill also grants him the right to use any of the Mysteries of Ancient Greece and Rome, which lets him draw upon any Noble Phantasm he's ever owned through his other Noble Phantasm, Perseus Khresmos. This is also implied to be what makes him compatible with any of the gods' nanomachines, which Athena warns would tear him apart if they rejected him.
• The Owl-Knowing One: Minerva, Athena's last remnants and terminal, takes the form of an robotic owl that looks half-finished with half its wire frame showing.
• Painful Transformation: Stealing Lostbelt Chiron's copy of the Zeus' Klironomia causes Percy's body to spasms as his body's structure is changed from the inside out before losing consciousness.
• Papa Wolf: His Lostbelt counterpart demeaning his student Percy as a "waste of time" makes Chiron look positively murderous.
• Parental Favoritism: Weaponized in the form of Percy's Noble Phantasm: Poseidon Asphalios: An Ocean of Blessings for the Most Beloved. As Poseidon's favorite son, he has his full blessings on top of the skills of all of the other sons of Poseidon but better. This is why he has an A+ Rank in Stout Arm of Brutality compared to Orion's B+, Poseidon's armor, Divine Core, and trident, and the same invulnerability as Caenis.
• Posthumous Character: Apollo, Ares, Athena, Hades and Hestia were all destroyed during the Olympiamachia. Athena managed to leave behind the remnants of her knowledge and memories in the form of her terminal, Minerva, and Hephaestus was cut in two, leaving a part of him in Atlantis and another part of him in Olympus.
• Power-Up Food: Percy has access to Moly, the herb Hermes gave to Odysseus to protect him from Circe, in the form of the multivitamins Hermes gave him in The Sea of Monsters. Eating them bumps up Percy's Magic Resistance to EX, allowing him to weather small uses of divine power. Percy also takes in Ares' and Athena's Klironomias by drinking them.
• Prongs of Poseidon: Poseidon's Authority over earth and sea is embodied in his Noble Phantasm: Trident Ocean Ray – Sea God’s Trident. Due to being favored by Poseidon, both Percy and Caenis have it even though Poseidon still exists in the Lostbelt.
• Psychic Dreams for Everyone: Percy has a dream of Olga Marie on the day of her death, seeing everything up the point that the control room was bombed and listening to all of her thoughts. He then sees the Priestess of the Alien God before the dream ends. This is also why Percy is able to recognize Wodime on sight, though he doesn't know that Wodime is now one of the Crypters who began the Lostbelt crisis. Percy later gets another dream about the circumstances that led Zeus to usurp his fellow Olympians' Authorities.
• Rain of Arrows:
  • Lostbelt Chiron's forces fire hundreds of arrows at Percy for every one of his heartbeats. Each arrow is strong enough to shred a tree trunk or shatter the ground, but their aim is so perfect that Percy is able to dodge or intercept them relatively easily.
  • Zoe Nightshades fires arrows in the form of lasers from her constellation in the sky to assist Percy while he's fighting, shooting enemies along the swing of Riptide's blade.
• Red Eyes, Take Warning: Caenis' normally greyish-blue eyes glow red from the sheer rage she feels towards Poseidon and Percy by extension.
• Reluctant Fanservice Guy: Percy is not pleased when he learns that his new armor comes with a gratuitous Cleavage Window that shows off his pecs and abs and feels indecent because of it (though he's glad his armor includes pants, unlike Caenis' version). So when he comes across a village whose inhabitants rush to serve him as the son of Poseidon, one of the first things he asks for is a shirt.
• Sacred Hospitality: As per the standard for Ancient Greece, the citizens of Atlantis greet Percy warmly after mistaking him for Poseidon. They cater to his every whim and he tries to return the favor by protecting them from Caenis, invoking it in return.
• Schmuck Bait: Percy goads Lostbelt Poseidon into reading his mind by floating the hypothetical situation that Pan-Human History has someone as strong as Kirschtaria on its side. If Poseidon is so well-protected against information warfare, then there would be no risk.
• Sins of Our Fathers: Caenis absolutely hates Percy and tries to kill him for being a son of Poseidon because Poseidon had raped her. Percy admits to feeling sympathy for her when he hears her name and realizes why she's so obsessed, though of course not enough to not defend himself.
• Situational Sword: By calling upon Riptide's True Name, Percy is able to call upon Zoe's aid from the stars to fire a barrage of lasers at his opponents. However, a number of conditions must be met for it to be used at full power: "That the user can see the stars," "that the Moon can see the blade," and "that the Huntress is beside the Moon". In addition, it can't use its full power in a texture incompatible with the concept of the Heavens, but the Atlantis Lostbelt allows it to showcase its devastating might.
• So Last Season: Discussed by the author. He's aware that Gilgamesh originally held the title of being the strongest character in the Nasuverse courtesy of owning Ea and having enough Noble Phantasms to take down even Arcueid Brunestud. This has made Gil the de facto measuring stick for power in the Nasuverse, but even he has been eclipsed by the Servants shown in Fate/Grand Order, namely gods like Lostbelt Zeus, Arjuna Over Gods, and other top gods like Quetzalcoatl and Ishtar at their full strength.
• Spared by the Adaptation: Thanks to Percy's assistance, Pan-Human Chiron survives his battle with Lostbelt Chiron, giving him an opportunity to escape otherwise certain death.
• Speaks Fluent Animal: One of Percy's Combo Platter Powers is the ability to telepathically communicate with any animal under his father's domain, namely all aquatic life and horses. He speaks to some of the fish in the ocean while trying to figure out where he's summoned and the strange nature of the islands.
• Split-Personality Merge:
  • Chiron explains this as a possible risk of absorbing his Lostbelt counterpart. Absorbing him would mean reliving Lostbelt Chiron's life, meaning that Chiron would experience 14,000 years of memories in an instant. Because of this, he isn't sure if it will change his personality or not, and Percy is so unnerved that he offers to just kill Lostbelt Chiron on the spot. But Chiron takes the plunge anyways, deeming the information Lostbelt Chiron has too valuable to pass up. Luckily, Chiron pulls through and is still the same as ever.
  • Hephaestus is worried when he learns about this, as the new merged Chiron could be a Bitch in Sheep's Clothing waiting to backstab Percy when he's least expecting it. Percy acknowledges the possibility, but decides to trust him anyways, since anyone could betray him, but that's just how life works. And one of the most important figures in his life, Percy would like to trust Chiron more than anyone.
• Spotting the Thread: While exploring underwater, Percy apparently sees the Fantasy Tree, but realizes it is an illusion when he notices it is not disturbing the water currents.
• The Straight and Arrow Path: Chiron and his Lostbelt counterpart are both masters of the bow, flinging arrows at machine gun-like speeds with unerring accuracy.
• Sufficiently Advanced Aliens: The Greek gods were originally machines from another, dying universe who made their way to Earth in search of a new home, settling on Earth and deciding to serve humans after the last of the aliens that created them died out. The fact that they're all robots baffles Percy, who asks if Chiron is a robot too. Percy himself is classified as an "Anti-Ship Amphibian Combat Unit/Pseudo-Organic Planetary Scouting Unit registered to the Planetary Environment Modification Plant-Ship Poseidon".
• Suicide Attack: After Percy dispatches his men, Lostbelt Chiron resorts to detonating them with the nanomachines inside in hopes of hurting Percy.
• Superpower Lottery: Being Poseidon's favorite son has its perks, and all the quests he went on as a teenager has left Percy with a treasure trove of Noble Phantasms and powerful skills, including no less than three forms of Nigh-Invulnerability, his father's Divine Core, Authority, armor, and trident, on top of access to Heracles' personal Noble Phantasm, Nine Lives. His Noble Phantasms, Poseidon Asphalios and Perseus Khresmos, also allow him to use every skill inherent to another child of Poseidon as well as any Noble Phantasm he's used in the past. Lampshaded by Chiron, who after getting over his initial shock at seeing Percy's capabilities, remarks that Percy always had a tendency for standing out.
• Super-Senses: As a side effect of the time he hosted Nekhbet to defeat Setne, Percy has A+ Rank Clairvoyance suited towards observing the true nature of things, such as the very fabric of reality. Because of this, he's able to see Artemis orbiting the Earth in space from his position on the ground.
• Super-Strength: Percy's already great strength becomes even more pronounced with his Stout Arm of Brutality skill, letting him throw Lostbelt Chiron like a baseball.
• Suspiciously Specific Denial: Percy definitely did not spend his first night in the sea because he was afraid being seen. He's investigating. Definitely.
• Sword Beam: Riptide can fire "arrows" in the form of beams representing its connection to Zoe Nightshade, who assists Percy with laser beams along the path of Percy's swings.
• Sympathy for the Devil: After learning Caenis' identity, Percy is still willing to tear her apart for assaulting him but can't bring himself to hate her anymore, acknowledging what his father did to her is unforgiveable.
• Takes One to Kill One: Poseidon and Demeter are the same class of ship due to their mutual use in terraforming and manufacturing. Because of this, Percy's possession of Poseidon's Authority allows him to unravel Demeter's Authority, nullifying her Klironomia and enabling him to kill those who would otherwise simply heal away their injuries.
• Taking You with Me: Discussed by Percy. He tells Hephaestus that giving anything less than his all against Poseidon is tantamount to suicide anyways, so he asks Hephaestus to crank up the power of his copy of Poseidon's Trident to the maximum rather than trying to make it safe for him to use. If his body is going to crumble from handling the power of a god and he expects to die anyway, he might as well make it a fight with some chances. After that, he'll leave the task of saving the world to whoever comes after him.
• Temporary Bulk Change: The muscles of Percy's arms briefly bulge in size while he's using his Stout Arm of Brutality skill, allowing him to easily thrash Lostbelt Chiron with brute force.
• Tempting Fate: Double Subverted. When Percy is about to kill Caenis, he loudly announces his intentions in case she's some god's favorite child, lover or ex-roommate, expecting to have someone swoop in to save her. When no one appears, Percy shrugs and gets ready to go through with it until Wodime tears a hole in space and tells him to stop.
• There Can Only Be One: Normally, Chiron would have been absorbed by his Lostbelt version almost immediately due to the latter being the more powerful existence. Chiron is only spared because the gods were unsure of how this would affect Lostbelt Chiron. Because of this, Percy uses his nanomachines to steal the critically injured Lostbelt Chiron's own to allow Chiron to take over his body.
• The Power of Family: Percy hopes that his relationship with his father will be enough to at least start a conversation with him and get him to stand down. After Lostbelt Poseidon reaches into Percy's memories, he's willing to at least speak with Percy and soon finds himself caring enough to try and get him to turn back rather than fight him. This is all in spite of Zeus' brainwashing to turn him into an attack dog.
• Thou Shalt Not Kill: Downplayed. Percy is familiar with slaying monsters and is ready to kill his foes, human or not, without hesitation. But that doesn't mean he's fine with killing others and is especially disturbed to learn that he's been summoned to destroy an entire world, killing everyone living on it in the process.
• Top God: Zeus is still the king of the gods and the most powerful among them, having usurped their Authorities and very beings to defeat Sefar 14,000 years ago. Percy even admits that as much as he might disagree with Zeus's personality, policies, or actions, the one thing he'd never dispute is that Zeus could tear him apart in a one-on-one fight. This even extends to his Klironomia. While the nanomachines are able to operate independently alone, Percy can feel the Zeus Klironomia enforcing a strict hierarchy upon the others after he steals it from Lostbelt Chiron.
• Underestimating Badassery: Having helped slaughter many Servants before and being unaware of Percy's existence, Lostbelt Chiron doesn't think much of Percy joining the fray against him. As a result, he's almost completely blindsided by Percy's ability to weather all of his attacks and kick his army's ass before rushing off to do the same to him.
• Villain Has a Point: Percy admits that Luke had a point in wanting to rebel against Olympus: the gods rule from afar and shove all of their problems onto demigods, who they rarely acknowledge, leaving the demigod youth feeling cheated and abandoned. This on top of their dickish actions from mythology. This is why Percy turned down godhood in favor of rectifying the circumstances that led to the Battle of Manhattan and Kronos' near-victory. Percy also finds himself agreeing with Wodime that it would be immoral to kill countless people who have done nothing wrong with their lives and were simply doomed to a timeline destined for pruning.
• Walking Shirtless Scene: Defied. Percy feels uncomfortable walking around with his pecs and abs showing in a ridiculously gaudy-looking set of armor he had no say in wearing, so he puts on a shirt the first chance he gets.
• Walk on Water: Being the son of Poseidon allows Percy to harden water into a flat surface he can walk on. He frequently uses this to fight others on the surface of the water where he has a foothold advantage. Due to having the blessing of Poseidon, Caenis has this ability too.
• Weapon of X-Slaying: Due to being forged from Celestial Bronze and being previously owned by two amazing monster hunters, Riptide is extra powerful against Magical or Demonic Beasts.
• Willfully Weak: Percy purposefully restricts his usage of his more potent abilities like manipulating water, creating storms, and starting earthquakes out of fear of attracting his father's attention.
• Woman Scorned: Zoe still hasn't forgiven Heracles for taking her sword and essentially writing her out of history. Because of this, Riptide suffers a rank down in Heracles' hands and calling upon her aid will likely end up making Zoe fire upon Heracles too.
• You Can't Fight Fate: Embodied and weaponized by Percy's Noble Phantasm, Perseus Khresmos. His adventures and experiences are stored and recorded in his string of fate, which Percy is able to access at any time. This, combined with his Savior of Olympus skill, allows him to draw upon every Noble Phantasm he has ever possessed by pulling it directly from his fate of possessing them.
• You Don't Look Like You: Percy notes that Chiron looks younger than he remembers and has blonde hair on top of not having horse legs. Despite this, Percy is able to recognize him on sight and rushes to his aid, though he's quick to bring up the discrepancy when they meet up.
  Chiron: Percy?
  Percy: [relieved] Looked like you could use some help. Gods, am I glad you remember me. I wasn’t sure you would, in this world. You look, uh, different.
