The Heroes of Olympus

Warning: This page contains spoilers for the first series and the first two books of the second.

A Sequel Series to Percy Jackson and The Olympians by Rick Riordan. It takes the same setting as its predecessor and is set a short time after.

The first book, The Lost Hero, was released on October 12, with two chapters released online. The story follows a half-blood, Jason (like that Jason) finding himself in a school bus with absolutely no memory of who or what he is, along with a girl, Piper, and a boy, Leo. The three turn out to be half-bloods and run into Annabeth (from the first series) and someone named Butch, who are looking for a disappeared character.

The second book, The Son of Neptune, was released on October 4th, 2011. The first chapter can be read over yonder.

The third book in the series, to be titled The Mark of Athena, is slated for October 2, 2012. However, a sneak peek of the first chapter was read aloud by Riordan while on tour for a different book. Video of the reading can be found here while a transcript of what was read can be found here.

General tropes about the setting carried over from Percy Jackson should be left neatly at the bottom of the page.

Please place tropes which only apply to one character on the character sheet. The main article is getting cluttered, and we're only on book two!

This series provides examples of:
""As they trudged on, Percy thought about all the crazy places he'd seen. None of them left him speechless like Alaska. He could see why it was a land beyond the gods. Everything here was rough and untamed. There were no rules, no prophecies, no destinies--just the harsh wilderness and a bunch of animals and monsters. Mortals and demigods came here at their own risk.""
 * Abusive Parents/Parental Abandonment: Jason's mom.
 * Queen Marie, Hazel's mother, actively (if unintentionally) cursed her daughter and resented Hazel for it when bad stuff started happening.
 * Subverted with her father, Pluto. His deliberately turning a blind eye to her means she won't have to go back to the Underworld, even though she's supposed to be dead.
 * Adults Are Useless
 * Affably Evil: All the Giants are actually rather charming in their own twisted ways.
 * Affirmative Action Legacy/Affirmative Action Girl: While a good majority of the characters in the original series were Caucasian, of the five new heroes, one is Native American, one is Hispanic , one is African American , one is Chinese-Canadian -- and only one is white. See Seven Token Band.
 * Alaska: The land beyond the gods. Where Percy, Frank, and Hazel go on their quest in Son of Neptune.

"Jason:
 * All Your Base Are Belong to Us: Polybotes' invasion of New Rome.
 * Amazon Brigade: The actual Amazons show up in Seattle.
 * Amazon Kinzie Wants Percy Jackson: He doesn't return the sentiment.
 * Does Not Like Men: Subverted. The Amazons like men perfectly well. They just like men to know their place even more.
 * Lady Land: Amazon HQ.
 * Product Placement/Hidden in Plain Sight: Apparently And they apparently read on their Kindles when they ought to be on guard duty (though it's less likely to be Product Placement than Just for Pun).
 * Thanatos uses an iPad to keep track of the dead.
 * Amnesiac Lover: Averted. Jason quickly reciprocates Piper's feelings, but he doesn't want to lead her on when he isn't entirely sure how he feels about her (first because of his amnesia, then because it turns out, and then because of ).
 * Subverted with.
 * Ancient Grome: The ultimate aversion.
 * And the Adventure Continues
 * Animorphism:
 * Artistic License Economics: King Midas's plan. Let's just leave it at that.
 * Well, he WAS born before they really had invented it yet...
 * Art Shift: The covers of the first two books. Probably deliberate, to accentuate the more culturally refined nature of the Greeks (featured in The Lost Hero) verses the rougher, grittier  (featured in [0 xx U/Td 5 GLW Hnq 6 I|Td 5 GLW Hnq 6 I]/AAAAAAAABQE/e1I6_B_8bF4/s1600/Son
 * Ascended Extra: "D-list goddess" Khione plays a major role. Gleeson Hedge (referenced once in TLO) is another example. Will Solace and Jake Mason may also apply.
 * Hylla, Circe's assisstant, last seen in Sea of Monsters turns up again as.
 * Asskicking Equals Authority: One of the two possible ways to get promoted to praetor.
 * Still in full effect for  too.
 * Back From the Dead: Medea, Midas and his son.
 * Also, Hazel and after the war games, Gwen (aka: Centurion Shish-ka-bob).
 * Monsters coming back from the dead in nothing new. Unfortunately, due to, monsters come back mere seconds after being slain.
 * Let's just knock out all the tropes associated with "The Doors of Death are open, and Greek villains and monsters are coming back to life willy nilly":
 * Back From the Dead:
 * Death Is a Slap On The Wrist:
 * Death Is Cheap
 * First Episode Resurrection
 * Resurrected for A Job
 * Badass Army: The 12th legion.
 * Badass Boast: Jason and both during their boasting match.

Leo: Wow, dude. You been eating red meat?"

"Percy:"
 * Percy to, “You. Me. To the finish.”

"Hazel: "I didn't even know we had a navy.""
 * Badass in Distress/Distressed Dude:
 * Bag of Holding: Leo's magic toolbelt, which can produce any sort of tool (so long as it's not too huge) and apparently breath mints.
 * Bag of Spilling: In The Son of Neptune, Percy loses most of his memories. He is still effectively invulnerable due to his Curse of Achilles and repeatedly defeats the gorgons. Soon after June tells him that for him to enter Camp Roman he must lose his Curse of Achilles, leaving him vulnerable to harm, and he chooses to enter.
 * Basilisks Are Abhorrent: And they destroyed Frank's bow!
 * Batman Gambit: Double subverted.  It works.
 * Beauty Is Never Tarnished: Being claimed/blessed by Aphrodite invokes this. Piper tries her hardest to mess her appearance up, but her looks just keep fixing themselves for days afterward, to Piper's irritation.
 * Big Bad:
 * Big Badass Bird of Prey: The giant eagles at Camp Jupiter.
 * Big Badass Wolf: Lupa.
 * Big Damn Heroes:
 * Cavalry Betrayal: Polybotes's army assumes the Amazons are there to attack New Rome.
 * Blessed With Suck/Cursed With Awesome: A good portion of the main cast has to deal with powers that can be either crappy or awesome, depending on the situation.
 * Leo, in addition to his technological talent, has . Great for fighting monsters, right?Yeah, except for the fact that   And Apparently the last son of Hephaestus with the ability   So that should give you an idea of what we're dealing with here.
 * Hazel can summon precious minerals from underground . While the ability has come in useful before, it absolutely ruined her   life, as the stones curse anyone who holds onto them...
 * Frank Zhang could darn well be the Trope Codifier for both.
 * Blond Guys Are Evil: Octavian. This is the second time Riordan has made the evil guy from camp an older blond dude. Subverted by Jason.
 * Blood Magic: Gaea plans to use Percy’s blood in some kind of sacrifice to bring down the gods.
 * Break the Cutie:
 * Broke Your Arm Punching Out The Titans: The gods of Olympus are in no shape to fight a war against the giants precisely because they're still broke from fighting the Titans and Typhon.
 * Brought Down to Badass: Percy.
 * Call Back: Ma Gasket shows up in Son of Neptune wanting revenge on Jason, Leo, and Piper. Percy also shows up to reclaim his place as a main character after being absent for the first book.
 * The Captain: Roman praetors.
 * Challenging the Chief: How the Amazons get their queens. This comes back to bite them when their Queen, who would side with the romans, is challenged by a Gaea-backed usurper who keeps on coming back to life whenever she is killed, winning through simple attrition.
 * Changing of the Guard: So far, Percy is the only old character who is part of the Seven. Possibly Annabeth, too.
 * Charm Person/Jedi Mind Trick: Piper, Drew, certain other children of Aphrodite, and Medea.
 * Chekhov's Gag/Brick Joke: Five books later, Annabeth proclaiming the Laistrygonian giants to be "Canadians" in Sea of Monster is brought back up in Son of Neptune where Percy calls them Canadians... in front of genuine Canadian Frank Zhang. Frank is not pleased.
 * Chekhov's Gun: The bronze dragon. Festus first appeared in the shorty story collection "The Demigod Files."
 * And now Terminus. Seemingly a one-off gag, but then comes back in the climax
 * Gorgon blood.
 * Cliff Hanger
 * Clockwork Creature: Festus.
 * Color Coded for Your Convenience: Orange and purple
 * Compelling Voice: Medea, Drew and Piper all display this ability.
 * in "The Son of Neptune".
 * Continuity Nod: In Percy Jackson and The Olympians Sea of Monsters Annabeth regrets forgetting her special coconut sunblock from Medea's department store.
 * And the bronze dragon also makes its first appearance in The Demigod Files.
 * Also, while shopping in shopping mall, a bronze breastplate that is corroded with acid is mentioned along with other merchandise belonging to deceased campers. This troper can't be sure, but her first thought was that the armor belonged to   and was last used by.
 * The Armor coupled with 's conversation with doubles as Fridge Brilliance when you realize
 * Nereus, the old man of the sea, last seen in Titan's Curse, makes a blink-and-you'll-miss-it but funny cameo in Son of Neptune.
 * Vitellius, in Son of Neptune, asks whether or not Percy cleans stables during their first conversation. Since Percy's memory has gone, he can't remember that he did in Battle of the Labyrinth.
 * Conveniently an Orphan: Most of the main characters except for Percy and Piper.
 * Cool Boat:  Averted by the beat-up dinghy that constitutes the entire Roman navy.
 * Cool Boat:  Averted by the beat-up dinghy that constitutes the entire Roman navy.


 * Cool Sword: Jason's Imperial Gold sword, which can also turn into a javelin- see Swiss Army Weapon.
 * Crazy Prepared: The Zhangs have an armory in their attic that's almost as well stocked as the one at Camp Jupiter. They have everything from swords, bows, arrows, spears, even potato launchers for taking out earthborn. It comes in handy. (Don't forget the water-hose on the roof!)
 * Creator Provincialism: Noticeable aversion in comparison to the first series. Instead of all America, all the time (with a few digs at Canada), Heroes of Olympus looks set to be much more international: a Chinese-Canadian main character (complete with an exceedingly rare tip of the hat to Canada's military) a book cover set against the Quebec City skyline, a climactic moment in British Columbia, and a quest that looks set to take the heroes back to the original Rome and Greece.
 * Crossover Cosmology: When meeting his dad for the first time in a dream, Leo exclaims, "Holy Mother!" Hephaestus chides him, "It's 'holy father', boy. I would think you'd know the difference."
 * Topped in The Son of Neptune by rainbow goddess Iris, who hasn't quite decided whether her personal creed should be...Buddhism or Taoism. Amusingly, Buddhism canonicaly sees nothing wrong with being a god and buddhist at the same time.

""He'd perfected his wolf stare over the last few months - a look that said: However bad you think you are, I'm worse""
 * Crush Blush: Ella, Tyson.
 * Curb Stomp Battle: Percy, Frank, and Hazel against the First and Second cohorts in the war games.
 * Also, Hazel and Frank against  It wasn't a totally one-sided battle, but they really gave him a beatdown.
 * Cyclops: Ma Gasket and her sons..
 * Darker and Edgier: Continuing the trend from the original series.
 * Dark Secret: Piper thinks she'll have to betray her friends.
 * Death Is Cheap: For the monsters, which are regenerating within hours if not minutes because  made a new tunnel into Tartarus.
 * Eventually, even some demigods are able to come back from the dead without even realizing that they are..
 * Death Glare: Used by Percy in Son of Neptune.
 * Death Glare: Used by Percy in Son of Neptune.

""That was sarcasm, wasn't it? Machines don't have sarcasm, usually.""
 * Deceased Parents Are the Best: Esperanza Valdez and Emily Zhang. Subverted with Marie Levesque and Jason's unnamed mother.
 * Delinquents: Jason and his friends are apart of a 'Wilderness School,' a Boarding School in Nevada for 'bad kids.'
 * Demoted to Extra: Annabeth, Chiron, and Clarisse.
 * Grover has officially joined the list as of Son of Neptune.
 * Did You Just Dump The Queen Of The Gods In The Little Tiber?
 * Iris, the Messenger goddess, is outside. She throws a ding-dong at him.
 * Did Not Do the Research: The time that Vitellius lived in was around the death of the Republic, the only battle in which a Legion Eagle was taken was at the battle of Carrhae against the Parthians, not during a Jewish rebellion.
 * Averted. See the other wiki The Twelfth did lose it's eagle in the Jewish Revolt.
 * Disney Death: Oh no, Percy Jackson just fell off a cliff in a No Escape but Down situation! ... wait. He fell into water.
 * Does Not Understand Sarcasm: Hephaestus. He's not too smart dealing with organic life forms.


 * Does This Remind You of Anything: An amnesiac hero with a ton of martial skills and esoteric knowledge named Jason.
 * Doting Parent: I never thought I'd say this, but
 * Also, Hades/Pluto. Probably the most involved parent of all the gods.
 * Don't forget about Hephaestus.
 * The Dragon:.
 * Dramatic Wind: Invoked and lampshaded by Jason during his boasting match with.
 * The Dulcinea Effect: Probably not what Reyna meant when she asked for Percy’s help, but Percy interpreted it that way. See Ship Tease.
 * Dug Too Deep: Invoked. . After realizing this,.
 * Easy Amnesia: Zigzagged. Both Jason and Percy have their memories stolen by Hera/Juno,  YMMV as to whose amnesia was easier.
 * Elemental Powers
 * Earth: Hazel
 * Fire: Leo
 * Wind: Jason
 * Also, Shock and Awe
 * Water: Percy
 * Heart: Piper
 * Death/Darkness: Nico
 * Annabeth and Frank got shafted on the elemental powers thing, though.
 * Eternal Recurrence: How many times do you think the Titans and giants will keep going after the Olympians?
 * Invoked with Monsters, which regenerate to be fought again, and with immortals, as they don't change (much). Addressed further in The Kane Chronicles, which share a universe.
 * Invoked with Monsters, which regenerate to be fought again, and with immortals, as they don't change (much). Addressed further in The Kane Chronicles, which share a universe.


 * Everything Sounds Sexier in French: Aphrodite apparently thinks so. Children of Aphrodite can speak and understand French. Why? Because it's the language of love, of course.
 * Subverted in Son of Neptune. Frank and Hazel try to talk to each other in French, but they’re pretty bad at it.
 * Expy: Piper's father is mentioned to have played The King Of Sparta and there is mention of The Poster which the two considered funny until it hit the internet.
 * Extremely Short Timespan/Time Bomb/Cosmic Deadline
 * Fan Nickname: / / for.
 * Fauns and Satyrs: They are considered to be the same thing.
 * Hedge mentioned that "Fauns are Roman." Seeing as how Roman demigods are quite different from their Greek counterparts, it wouldn't be surprising if this was the case with other magical creatures.
 * Possibly justified. They could have indeed become more or less the same if people began to believe that they were with different names. In the first series, it was said that the Titans Helios and Selene faded after the Romans reassigned their duties over the sun and moon to Apollo and Artemis, so it's not unprecedented for them to have been blended them together into the same creature/species.
 * And as of Son Of Neptune, we've seen fauns, and they are, in fact, not the same as satyrs, to Percy's confusion.
 * Fire Forged Friends: Played with. Leo and Piper think they've been friends with Jason for a while, but even when this is proven to be false, they're still tight from the time they have spent together.

Also, Pipers father says that he thinks " That Indian and Greek stuff is all bull " "“So you do have a plan?” Octavian asked skeptically.
 * Foreshadowing: When Reyna summons Percy to a private meeting with her in the principia,.
 * Gaias Revenge: Proper.
 * Though it's really in name only. Gaia isn't really angry at humans polluting the environment, she's angry at the Gods for killing the Titans. Destroying the gods and thus unmaking western civilization would have a similar effect, however.
 * And Gaea's powers appear to be more Earth based and less nature based: that was Pan's domain.
 * Genius Ditz: Quite a lot of characters, including Leo, Frank, Percy, and Ella.
 * Gentle Giant: In their native home, the Hyperborean giants are peaceful.
 * Getting Crap Past the Radar: Schist.
 * Much of Percy's intepreting for Arion consists of this.
 * In "The Lost Hero", it mentions that Drew dumped, "everything from the bathroom waste bin- some pretty nasty things- all over the floor".
 * In "The Lost Hero", it mentions that Drew dumped, "everything from the bathroom waste bin- some pretty nasty things- all over the floor".
 * Good Scars Evil Scars: Jason has a little one on his lip from trying to eat a stapler when he was two. Lit, Midas' son and bodyguard is covered in them.
 * G Rated Drug: Dakota, a son of Bacchus, is addicted to Kool-Aid.
 * Grievous Harm With a Body:
 * Gunship Rescue:.
 * Harping On About Harpies: In Son of Neptune. However, Phineas . This isn't exactly what happens.
 * Have You Seen My Gods: Olympus has been closed and the gods have gone MIA.
 * In The Son of Neptune he seems to have changed his mind (or bowed to the inevitability of the others meddling making the plan moot), allowing Mars to order a quest.
 * Hell Yes Moment: The Fifth cohort after Percy, Hazel, and Frank storm the defenders’ fortress during the war games.
 * Heroes Unlimited
 * Heroic Sacrifice: is initially thought to have  Then, after, they go back to the
 * The Cavalry: Amazon reinforcements in New Rome.
 * Holding Hands: Percy and Reyna after.
 * A House Divided:
 * Human Popsicle: Quite a few, from those in Boreas' fortress and . Midas' "house guests" probably count, too.
 * Indy Ploy:

Percy looked at his teammates. “We go to Alaska as fast as possible...”

“And we improvise,” Hazel said.

“A lot,” Frank added."

"The coffee shops were doing a brisk business, and street musicians filled the air with the sounds of guitar, lyre, panpipes, and armpit noises."
 * Inelegant Blubbering: The Earthborn. "Yay-son! Where Yay-son? Kill Yay-son!"
 * Instant Awesome Just Add Dragons: Festus
 * Interspecies Romance:
 * Invisible to Normals: The entrance to Camp Jupiter and New Rome.
 * It Belongs in A Museum: Piper initially believes this of the dagger she gets from Annabeth (it had once belonged to Helen of Troy). Annabeth tells her that they're surrounded by Ancient Greek stuff at camp, but weapons like that are the heritage of the demigods and are meant to be used.
 * Jedi Mind Trick: Charmspeaking.
 * The Last of These Is Not Like the Others:

"Leo: See, lady, that's what happens to snow in Texas. It. Freaking. Melts."
 * Late Arrival Spoiler: After taking most of The Lost Hero to be revealed, Gaea being the new Big Bad is spoiled in the first chapter of Son of Neptune.
 * Locked Out of the Loop: The gods, Chiron, and Lupa are keeping a big secret. The Lares of Camp Jupiter, too.
 * A bit of story hints is that Chiron never mentioned.
 * Long Lost Relative/Everyone Is Related:
 * Hazel is  sister and Frank turns out to be.
 * Leo is related to
 * Kill It With Ice: The result of getting hit by Hyperborean breath. Percy uses this to his advantage.
 * Khione, the goddess of snow, is fond of doing this.
 * Love Dodecahedron: Shaping up to be one between Piper, Jason, Reyna, Percy, and Annabeth, in that order.
 * Love Triangle: There is potential between Hazel, Leo, and Frank, but it remains to be seen if there will be one.
 * Mama Bear: An evil example with Ma Gasket.
 * Meet Cute: Piper to Jason.
 * Mistaken for Spies: And Percy hates it.
 * Muskeg Sucks
 * My Greatest Failure: The Romans lost their eagle standard in a disastrous campaign in Alaska in the 1980s. They're still sore about it.
 * They made up for it with some help.
 * Myth Arc: The Gigantomachy.
 * Mythology Gag: Pun not intended.
 * Names the Same: A Power Trio with members named Piper and Leo.
 * New Powers As the Plot Demands: On a series level, not within the series. Apparently certain children of Hephaestus can wield fire and all children of Aphrodite have apparently always been able to speak French, and some can charm-speak people into doing what they want. Justified as it's stated that controlling fire and charmspeaking are ridiculously rare, though some fans still think Aphrodite's children speaking French came from left-field.
 * There was only one named camper from the Aphrodite cabin in the first series, and she was never in a situation where speaking French would have been remotely helpful. Combining that with the fact that Piper seemed honestly surprised she could speak it, and it's fairly justified.
 * It was also never really delved into in the first series just what powers were granted to each god's children, and they seem to vary quite a lot among themselves as well.
 * Official Couple: Played with as of Son of Neptune. Hazel and Frank share a kiss after, but we don’t know if they’re officially going out by the end.
 * Oh Crap:
 * One Man Army: It was mentioned that Greek Heroes are trained to handle things solo compared to the Romans who rely on military teamwork. Percy's fighting style is repeatedly mentioned to be un-Romanly because of this.
 * One Steve Limit: Averted; though it'd be very hard to confuse, Midas mentions his daughter being named Zoe (not to be confused with the first series' Zoë Nightshade).
 * There's also a Jason at Camp Half-Blood playing Capture the Flag in Titan's Curse.
 * Our Dragons Are Different: Festus.
 * Poisoned Chalice Switcheroo: Percy manages to pull this on  with the  . He wins. Doubles as Out Gambitted.
 * Popular Is Dumb
 * Protect This House
 * The Power of Love:
 * Arguably, Still technically fits the trope, since only children of Aphrodite, goddess of love, can do this...
 * Power Trio: Jason, Leo, and Piper.
 * Percy, Hazel, and Frank.
 * Precision F Strike: Except that the word "freaking" is used instead of the normal phrase. Going toe-to-toe against an ice goddess is definitely one of Leo's Crowning Moments Of Awesome.
 * Precision F Strike: Except that the word "freaking" is used instead of the normal phrase. Going toe-to-toe against an ice goddess is definitely one of Leo's Crowning Moments Of Awesome.

"Percy:  *thunk*"
 * Pre Ass Kicking One Liner: "My turn."
 * Pre Mortem One Liner: Percy gets an awesome one in on.

"Frank: Welcome to Canada, idiot."
 * Frank also has a good one on

"Mars: Two hundred Romans and no one's got a pen?"
 * Prophetic Fallacy: Several new prophecies are mentioned in Son of Neptune, but are only half complete, leaving their ultimate meaning unclear.
 * Prophecies Rhyme All the Time: Lampshaded by Octavian who insists that Mars' prophecy rhyme and be cryptic and vague. Mars pulls out a grenade.
 * And turns it into a pen. Its mightier then a sword afterall.


 * Prophecy Twist: Spoofed by Mars in Son of Neptune. When asked by Octavian for a prophecy, a cryptic poem to guide the quest, Mars writes down the most bluntly straightforward prophecy ever with absolutely no ambiguity whatsoever.
 * Purple Is Powerful: The demigods in Camp Jupiter wear purple shirts.
 * Put On a Bus: As the series is an ensemble, focusing on several new characters as well as old ones, many of the main characters from the original Percy Jackson series take on secondary or cameo roles in the first two novels.
 * Raised By Wolves:
 * Real Men Wear Pink: Minor character Butch, a bulky dude with a shaved head and a face like a pile of bricks. His mother is Iris, the Rainbow Goddess. Got a problem with that?
 * Recycled in Space: The Argo II In Universe.
 * Rummage Fail: When facing off against, a nervous Leo reaches into his tool belt for a weapon and initially grabs breath mints before hastily swopping them for a hammer. He hopes no one noticed. This is turned into a Brick Joke seconds later when the perspective switches to Jason, and while evaluating his assets, he thinks about "Leo, who apparently thought he could defeat the armies of darkness with breath mints."
 * Sadistic Choice:
 * Also keeps with the History Repeats theme of the series, as
 * Several characters outright state that Percy’s gonna have to make another one sometime in the future, but likely won't be able to, due to his fatal flaw: loyalty to his friends above all else.
 * Save Your Deity: Jason, Piper, and Leo have to
 * Sealed Good in A Can: Percy was kept asleep by Juno for several months until the time was right for him to go to Camp Jupiter.
 * Hazel's time also qualifies.
 * Secret Test of Character: Percy thinks "June" is trying to put him through one in the beginning of Son of Neptune.
 * Hazel thinks it's a test too - she orders Frank not to fire, because she thought Percy was a god in disguise.
 * Self Made Orphan: Subverted and very tragic.
 * Seven Token Band: So far, the seven demigods of the prophecy include a Native American girl (Piper), a Latino (Leo), a Chinese-Canadian (Frank), a black girl (Hazel), and two white guys (Percy and Jason).
 * Particularly jarring when compared to the first series, where there were almost no minority characters. Makes some sense, as Rome was much more diverse then Ancient Greece.
 * Sir Swearsalot: Arion, according to Percy.
 * Ship Tease: Percy and Reyna as well as Reyna and Jason. While she and Jason weren’t a couple, Reyna is shown to be fond of him. It's also fairly common for praetors to become romantically involved. Then Jason disappears for eight months.
 * Shout Out: Jason suggests Leo jump off a building and yell "Flame on!"
 * There's a possible shout out to the show Charmed. The three main characters' names in the first book are Piper, Leo, and Jason, and one of Artemis's Huntresses is named Phoebe. While this might be a coincidence, if any of the other new demigods are named Paige, Prue, or Derek, we definitely have ourselves a major shout out.
 * owns a shop with the acronym R.O.F.L whose workers are called ROFLcopters. Also when complains about the samophlange.
 * The name "Perry" getting mentioned in the scene with Phineas.
 * Butch, the stable keeper at Camp Half-Blood, is a son of Iris, the Rainbow Goddess. He likes Pegasi. Remind you of anypony?
 * Not only that, but in Son of Neptune, Alcyoneus calls Arion a "little pony".
 * Piper is mentioned to have kaleidoscopic eyes.
 * There's a character called Gwen, who plays a major part in demonstrating that people can come back to life indefinitely. Perhaps coincidental, but it certainly reminds this troper of a couple characters in a certain TV series.
 * Shown Their Work: Rick Riordan has been around in real life, and used to be an editor for mythology books. And it shows.
 * He actually gets a lot of common misconceptions correct, such as how Thanatos is actually Death itself, and that Pluto was not just the lord of the underworld but also the god of wealth and the earth.
 * Staying Alive: Gaea grants her minions this.
 * Steampunk: Leo describes the Hephaestus cabin as steampunk. The term also applies to Festus.
 * Summon Bigger Fish: Summon Hyperborian giant, actually. (Or at least run underneath one.)
 * Summon Magic: Frank's godly parent gives him a spear tipped with a Dragon's Tooth that will regrow thrice. Breaking it off in the ground creates a zombie warrior roughly akin to the Terminator.
 * Suspiciously Similar Substitute: Reyna and Piper.
 * Swiss Army Weapon: Jason's weapon begins as a gold coin; a toss causes it to become an Imperial Gold sword or javelin on heads or tails respectively.
 * Taking You With Me:
 * Team Mom/Team Dad: and Chiron.
 * Team Pet: Festus.
 * Hannibal the elephant for Camp Jupiter as a whole.
 * Teeth Clenched Teamwork: There is quite a bit of animosity between Hera and more than a few demigods, particularly Annabeth and Thalia, but as Piper points out, they will have to work together to beat the Giants and.
 * They Plotted a Perfectly Good Waste:
 * Three Amigos: Jason, Leo, and Piper. Also Percy, Frank, and Hazel.
 * Title Drop: Hera/Juno does it while speaking with Jason about his destiny in the last chapter of The Lost Hero.
 * Token Minority Couple: Frank and Hazel.
 * Before that, Sammy and Hazel.
 * Token Trio: Jason as the quest leader, Piper as the Native-American love interest and Leo as the Latino Best Friend.
 * Also in "The Son of Neptune" with Percy (white), Frank (Asian), and Hazel (black).
 * Touche: Gaea’s grudgingly impressed by
 * Trojan Horse: Invoked by . It's not exactly a horse though, and nor is that actually the plan.
 * True Companions: Percy comes to consider Hazel and Frank as important to him as anyone from Camp Half-Blood.
 * Truly Single Parent: Aphrodite was born from the sea foam produced from Ouranus's body when it fell into the ocean.
 * Two Guys and A Girl: Both trios for both books 1 and 2.
 * Truly Single Parent: Aphrodite was born from the sea foam produced from Ouranus's body when it fell into the ocean.
 * Two Guys and A Girl: Both trios for both books 1 and 2.


 * Unusually Uninteresting Sight: Lampshaded when Percy runs through traffic with "June"  in Son of Neptune, most of the drivers, "just swirved and looked irritated, as if they had to deal with a lot of ratty teenagers carrying old hippie women across the freeway." Its The Mist again.
 * Voluntary Shapeshifting: All the gods can do this..
 * Walk Into Mordor: Book two resembles the grand old debate of Why didn't you just fly the giant eagles to Mor -- I mean, Alaska?
 * Because the Senate wouldn't give you any eagles of course.
 * Because Percy hates to fly on anything that isn't a Pegasus. Zeus might kill him for trying it.
 * Walking Wasteland: Hazel's life gives off this vibe. Wherever she goes, cursed gems and gold emerge from the earth that could kill innocents who picked them up. Pluto seemed to imply that most of his children are like this to some extent, Hazel just takes it Up to Eleven.
 * What Do You Mean Its Not Symbolic: A couple fans interpreted Octavian sacrificing the stuffed panda as a symbol for the death of the Greek and Roman rivalry, thinking the panda’s black and white coat symbolized the divide between both camps. This never comes up again and isn’t implied to mean anything else other than to be Played for Laughs.
 * White Male Lead: Subverted in Son of Neptune - Frank is the official leader of the quest.
 * Window Love: Piper and her father  do this through a video chat, with their hands touching on "opposite sides" of the computer screen. Your Mileage May Vary on whether this is possible, considering for this actually to work they'd have to put their fingers on the camera...
 * She's a child of Aphrodite. The Power of Love did it? Not all love is romantic afterall.
 * Winter Royal Lady: Khione.
 * The Windy City: Although Riordan doesn't seem to realize that Chicago is called the "Windy City" because of blustering politicians, not the weather. It is windy, though. Especially in the winter, when it's also freezing cold. Also, perceptions are important in this series, so if people think that Chicago is literally windy, that's where the Wind will go.
 * With This Herring: The only formal aid the Roman Senate gives Percy, Frank, and Hazel on their quest to save Camp Jupiter in Son Of Neptune is the piece-of-crap dinghy that sinks outside of Seattle.


 * A Worldwide Punomenon: Riordan being Riordan, almost as frequent as snarking. Special mention goes to Lupa, directed to Jason: "As always, you are our saving Grace."
 * Worf Effect: The Giants. Despite being stated to be the greatest threat Olympus has ever faced and three revealed being so far created as direct counters to the most powerful Olympians they have all be defeated fairly easily. Possibly justified in Porpheryion at least was not at full power. That and Percy is just that badass, so a villainous example of Overshadowed By Awesome?
