Fanfic / Digimon Xros Wars AU 02

"We are Xros Heart! Engrave it on your hearts!"

"Digimon Xros Wars: Alternate Universe 02!" Is a Fanfic that takes the original Digimon Xros Wars series and initially changes its plot by moving Akari from the human world to the Digital World (making her a Digimon), giving her the Red Xros Loader, and partnering her with Shoutmon and a Lopmon. The original, completed story can be found here on FanFiction.net and the Rewrite here on A03.

The first Sequel, a text adaptation of Zyuden Sentai Kyoryuger, called VAMOLA! Kyoryuger that takes place several years after the end of the first story, and is located on both FanFiction.Net and Archive of Our Own.

A third story, dealing primarily with the world of Last Exile: Fam, the Silver Wing on the Fanfiction.Net version, acts as a hybrid prequel to the Kyoryuger story. On AO3, Fam's backstory is included along with various other looks into the Multiverse that has been created, and acts more as a Compilation of random snips that lack as much of a cohesive story.

The story begins by introducing us to a battle field within a dream, shared by the main characters across two worlds. Soon after that, the sky breaks open, and our hero, Taiki Kudo, is dragged into the Digital World along with Zenjirou Tsurugi. They soon meet Akari Hinomoto and her partner Shoutmon, the Generals of the Xros Heart army, which was started by her father. The story then launches into a massive campaign that takes Xros Heart across the Digital World, freeing Zones from the evil Bagura Empire one at a time, collecting the Code Crown fragments as they go.

After collecting All remaining Code Crowns, Tactimon confronts Xros Heart and Blue Flare to inform then of the static-time-storms that have been chasing them throughout the story, only for one of these storms to interrupt their mock-battle and scatter them across time and space. Half of the team lands back on earth, without functioning Xros Loaders, along with new companions Marcus Damon and his partner Agumon, while the other half end up elsewhere in the Digital World, after the Bagura Empire has taken over and reformatted the Zones into Lands. In the struggle to return to the Digital World, Taiki's group restores their Xros Loaders and unlocks the ability to "Time Burst into Future Forms."

Upon returning to the Digital World, a week long battle begins to regain control of the Digital World, and, shortly there after, save the earth from the impending Bagura Invasion.

After defeating DarkKnightmon, a year has passed. Now Xros Heart works to uncover the mystery of the time storms that have been haunting them since their adventure first began. They discover the identity of this villain, named Quartzmon, and seek to unravel his plans before it is too late to prevent their earth from a similar fate to that of the earth that The Watch Maker came from.

Quartzmon having succeeded in his plans to create a new "Alpha Timeline" by destroying their version of Earth, Xros Heart searches the Universe to hunt down Quartzmon wherever he and his many copies hide across The Multiverse.

8/14 years after Quartzmon's original self is defeated, a splinter of his essence awakens the Deboss Legion, hidden deep beneath the ice in Antarctica, to exact his revenge on those who defeated him. Kaiyumi, now working as the head of NERV's latest giant robot project, ends up becoming the mentor to a team of heroes who have been chosen by her Voltasaurs to become their new Pilots. These heroes also happen to be the children of various Xros Heart Members, plus a few inter-dimensional friends.

With nine kids now comfortable in their positions as Kyoryugers, Quartzmon throws whatever he can at them, only to find that they'll act just like Xros Heart before them and find a way to make his plans fail, usually with The Power of Music and Dancing. After all, nothing says badass like defeating the living incarnation of a Planetary Apocalypse with a Samba beat!

After the conclusion of the Deboss Legion battles, the Kyoryugers seek out the world that Harime, Nui came from. Meanwhile, Fam thinks back on the events that lead to her first encountering the girl that proved to be incredibly hard to kill.

This story provides examples of:

• Aborted Arc: In the original draft, an entire plot line about Petsula being Lilithmon's daughter was cut out before it was even written, although some hints of it remained in the story. Come the Rewrite, said arc has been restored into the story proper.
• Action Girl: Akari and Sparrowmon.
• Adaptation Expansion: From Three "Acts" to Four.
• Alternate Self: Emmit and Clara Brown for Taiki and Sally.
• Alternate Universe: Exactly What It Says on the Tin. The story was made from the idea of "What if Akari was in the Digital World first?"
• All Just a Dream: Chapter 37 begins like this. It quickly turns into something much worse.
• All Stories Are Real Somewhere: played with at various points in acts 3 and 4, and is a definite result of the time storms.
• All There in the Manual: The author has made a "liveblog" where he goes through and comments on the story's plot. You can read that Here, and it serves as the manual of the story where he discusses the plot.
• Anyone Can Die: The Seven Swords' second act pulls this from the very beginning.
• Apocalypse How: Quartzmon starts a Species Extinction by erasing all those on earth older than 21. Then, he escalates it to a Planetary Physical Annihilation by planting Dagomon in the core of the Earth- setting the dominoes so that Dagomon escapes at the right moment to destroy the earth with a massive green-energy explosion. Meanwhile- Quartzmon bifurcates the timeline of everything at once and creates a Metaphysical Annihilation across the entire Multiverse in that splintered timeline. Is it any wonder that Quartzmon is the Big Bad of the series?
• Apocalypse Wow: The Act 3 finale goes to some lengths to show just how big of a scale Quartzmon's plan was.
• Arc Number: the number combination 816 appears frequently throughout Act 4.
• Asteroids Monster: Starmon's "Meteor Squall!" Attack is this with his subordinates.
• A Wizard Did It: Wizardmon gave Sally the training necessary to master Shapeshifting from her Human form to her Digimon form and back again. He helps Akari through a similar ordeal in Shinobi Zone.
• Badass Boast: Shoutmon paraphrasing the Eleventh Doctor's Pandorica speech in Lake Zone during Chapter 5, using Xros Heart's previous reputation to his advantage.
• Bearer of Bad News: Agumon delivers the news to Kristy that Marcus is dead at the end of X0VA-5. They're both pretty shaken up about it from what we can see.
• Berserk Button: Tactimon presses Corone's by indirectly calling her a bug/cockroach/insect. Due to DarkKnightmon's meddling, she doesn't take this well.
• Big Bad: Quartzmon. (See the Apocalypse How entry.)
• Big Damn Hero: Zenjirou in Shinobi Zone; he not only fights Musyamon without his trusty Rare Star Sword, but also breaks open a television set, finds an unclaimed Xros Loader inside, creates the Delta Rare Star Sword, and then proceeds to purify Musyamon down into his child form of Kotemon.
• Big Damn Heroes: Arguably all of Xros Heart at some point or another.
  • Joe pulls off an impressively timed rescue of those who wandered through a Time Anomaly underwater, kicking off the Xros Over.
• Bilingual Bonus: X0VA-5 has two Puppetmon talking to each other in Irish and Galician respectively. Their entire conversation is funny to read, as it's been sent through Google Translate.
• BFG:
  • Taiki Digi-Xrossed with Dorulumon still makes the Dorulu-Cannon.
  • Beelzebmon Xrossed with Revolomon makes him Death the Kid with wings.
  • RampageGureimon IS one.
• BFS: Zenjirou's Rare Star Sword, and Tactimon's Jatetsufūjinmaru.
• Big Red Button: The "Giant, Big, Red, Threatening Button That Must Never Ever Be Pressed Under ANY Circumstances (TM)" that Matadormon presses in Chapter/Episode 28.
• Breaking the Fourth Wall: The Narration delves into this on occasion, lamenting on the story at hand, and even saying that the Readers are lucky they don't have to see a certain event (The Love Love Dance).
  • Quite literally Broken in chapter 36, with Aradia pausing the story entirely to explain what the Honeybeemon were doing.
  • The Combo Record Scratch attack causes a meta-event across all of time and space... Which everyone promptly ignores to continue going about their daily lives.
  • One of Homestuck's various Fourth Walls is literally broken by DarkKnightmon's Green Miles attack.
• Break the Cutie: The story seems to be putting Kiriha through the ringer with the Seven Swords arc. First Kiriha has to wait through a good portion of the six month time skip in the Digital World for Taiki and the others to return from earth; shortly before they do he learns that Deckerdramon is dying. Second: He has to watch MetalGureimon get broken apart by Dorbickmon's Aegisdramon's attack. Third: MetalGureimon is absorbed into Neo Vamdemon, and despite the fact that they get him out, MailBirdramon appears to be in a coma inside the Digi Xros at the end of chapter 35. Fourth: he sees Nene bleeding out in reality after being stabbed in a dream. FIFTH: it's heavily implied that in the gaps between chapters 45 and 46 that he tried to kill Nene, though the exact details aren't clear. FINALLY: After rescuing Kiriha and Gureimon from the grimdark clutches of Anubimon, Deckerdramon is killed by Anubimon via one of his throwing daggers. Poor Kid.
  • Akari gets a minor one in the Seven Swords finale when Shoutmon throws himself in the line of an attack to save her..
• Brick Joke:
  • When Cutemon and Shoutmon Digi-Xros in Shinobi Zone into "Tengen Toppa Shou-Cutemon!", It comes off as a one-off Shout-Out. You don't expect Xros Five and Cutemon Digi-xros into Gurren Lagann: Xros Five! in Chapter 28.
  • You'd think it's just a Punny Name when you hear Sally's full name originally, but then comes Chapter 28 again with its Whole-Plot Reference to the Doctor Who episode "Blink."
  • Space Core appears briefly in the second half of the Seven Swords finale, being mentioned to still being carried forward from the momentum given to him in the last Intermission, and later on X0VA-1.
  • What happened to Gravimon? He appears at the end of an intermission episode, being orbited by Wheatley and Rick from Portal 2. After this, he then turns out to have been recruited by Quartzmon (AKA: his future self) to get his revenge against Xros Heart by means of destroying the earth.
  • Tagiru, when told about his future, makes a rather funny sound from the back of his throat. Yuu, ten chapters later, when told that Nene is pregnant, makes a similar sound from the same place. In X0VA-4, Daisuke makes the same sound twice.
• Call-Back: Shoutmon's speech in the Seven Swords finale echoes tones from his earlier boast in Island Zone.
• Climactic Battle Resurrection: Shoutmon says he'll be dragging the dead back to life kicking and screaming if he has to. He pulls it off, somehow. Kiriha makes Shoutmon promise not to die first if he ever has to do it again in X0VA-4.
• Continuity Nod: too many to count. It should probably have it's own page.
• Continuity Snarl: The story subtly changes tracks roughly halfway through the first arc, due to Digimon Xros Wars: The Young Hunters Who Leapt Through Time airing, and you can tell what the author was watching/reading at the time that each chapter was being written due to the increase of shout outs.
• Cool Boat: Olegmon's flagship the Good Friday.
• Cool Car: A Time Traveling DeLorean ripped straight from Back to the Future, in X0VA-1.
• Cool Ship: SpaceTrailmon, which gains the power to Time Travel later on in it's personal time stream.
• Cool Train: GrandLocomon, followed soon after by Kiichi's Locomon (Also a time traveling train, as of X0VA-4).
• Cute Monster Girl: Akari's Digimon form, as seen Here and Here.
• Deadpan Snarker: Quite a few characters do this on various occasions, but Sally is queen of this trope without a doubt.
  • In Fam's backstory, Senketsu snarks quite a lot due to no-one being able to hear him
• Did You Just Punch Out Cthulhu?: Victory King Xros Seven pretty much decimates the Horror-Terrorized Anubimon.
• Disappeared Dad and Missing Mom: Akari's father founded the original Xros Heart, presumably her mother was a member as well. They left her in Green Zone with the promise that they would return. They Didn't, and one day the Red Xros Loader fell from the sky and passed leadership of the team on to her and Shoutmon.
  • Tactimon spells it out for us. They're time travelers from the future who returned to said future after spending some Twenty Years in the past. With the implications that they'll meet the younger versions of her parents in one year, coincidentally lining up with the epicenter of the static storms. As of the Hunters finale, Akari is reunited with her parents, who have gone through the whole loop.
• Dreaming of Things to Come: Akari seems to have prophetic powers, having a dream about a critical event in the Death Generals Arc at the beginning of the first Jungle Zone chapter. She continues to have more simplified dreams after being turned back into a child and arriving in Shinobi Zone. She later has another one foreshadowing the climax of the Second arc, set to Infinity Mechanism, no less.
• Does This Remind You of Anything?: Akari's near murder by Flymon stinger comes off as a rape scene.
• Don't Explain the Joke: Eridan the Monitamon explains the funny spelling of DeltAntylamon's name, much to Aradia the Monitamon's annoyance. It becomes a Running Gag when Eridan tries the same thing with OmegaShoutmon in chapter 32 and beyond.
• Dynamic Entry: The Vespa team escaping the explosion from the Last Exile Earth to the Digital World by skipping rocks, sling-shotting around a sun, and then surviving reentry all before barely missing crashing into a flag-pole and crashing into a lake.
• Eaten Alive: Daemon is eaten by VenomMyotismon. Played for Laughs however, as Daemon is unharmed except for a whimpering cry for his "Mommy."
• Eldritch Abominations: The Anubimon that was working underneath Gravimon is descended from a group of Digimon who became these. He follows in their footsteps soon enough after he reveals this.
• Enemy Mine: Xros Heart and Blue Flare team up briefly with Tactimon when AncientVolcamon goes insane from his previous defeats.
• Evolving Credits: The Author makes note during his liveblog of the story that the second half of the Seven Swords arc was to have a changing opening sequence every time a major plot development occurred.
• Fanservice: Lopmon can Digi-Xros with Lila to become Turuiemon Xros Two Lilly, who is an alternate Version wearing a green skirt and a loose, green T-shirt with fairy wings instead of the usual the ninja clothing. Taiki lampshades this as Lila's will altering the Digi-Xrossed form.
  • Akari fights in a bathing suit during the first Magma Zone episode.
  • Nene wears the Love Love Dance costume in Dragon Land for no apparent reason other than to annoy Zenjirou and Lila.
  • X0VA-2: Kaoru has a scene where the camera pans up her legs from her feet- past the hips- past her chest- and to her face. She also reaches into Sanzomon's robes in an awkward spot for a keyring.
• Faux Shadowing: Nia the Lopmon explains that a White Lopmon sacrificed itself at the end of their life span in an act of friendship. Which also can count as a Mythology Gag towards the Anime itself where this actually happened.
• Feet-First Introduction: The first thing Taiki sees of Sally Sparrow are her dark grey snow boots, strangely out of place on a tree on an island's beach.
• Flat "What"
• Food Fight: Akari starts one with Shoutmon at a fancy restaurant.
• Foreshadowing: The opening narration of "Anyone being born in the Digital world is a Digimon" thing.
  • The Bearmon in prison comments about a Cutemon couple who had recently been transferred out of Magma Zone. Cutemon notes that it would be a wild coincidence but can't help but wonder if it's his missing parents. Chapter 28 confirms it's them.
  • The random Greymon in the first dream is not Blue Flare's Gureimon, but is supposed to be the one AncientVolcamon has later on.
• Gilligan Cut: Tagiru initially refuses to take Pagumon home with him. One cut later...
  He'd taken the Pagumon home.
• Half-Human Hybrid: Practically everyone when you let Wizardmon use his Shapeshifting spell.
• Hot Skitty-on-Wailord Action: Riska declares her love for Gureimon when it appears he's on the verge of dying. This is partially subverted as it's been stated before that there is a spell to turn Digimon into humans.
• Happily Married: Zenjirou and Lila and Kiriha and Nene as of the Hunters arc.
• Hijacked by Ganon: In X0VA-9, we find out that Quartzmon and Gravimon are the same person, which means the entire Hunters arc and beyond was all because of Gravimon.
• Hot Springs Episode: Having just left Island Zone, which actually had a beach, and arriving in Magma Zone, everyone wants to enjoy the Hot Springs. Akari lampshades this.
• Humiliation Conga: DeathMeramon in Magma Zone keeps getting blasted through walls; It's a miracle he survives as long as he does. Later, Neo Vamdemon in Vampire Land gets one as well.OmegaShoutmon's internal transformations affect the outside version of the Digi Xros, allowing him to make Neo Vamdemon literally shoot himself in the foot... Through his mouth. Somehow. ZekeGureimon follows it up by putting a giant record through Neo Vamdemon's knee. And finally OmegaShoutmon finishes it off by disabling the vampire's wings and then forcing a Reverse Digi Xros from the inside.
• I Am Not Left-Handed: In X0VA-4, Xros Heart holds back against VenomMyotismon until he fuses with Daemon and an alternate Myotismon... Then they blast him with a combined attack with half of the participants not even being present for the previous fight up until that point.
• Interspecies Romance: Played with with Shoutmon and Akari, but ultimately subverted. The opening narration explains that "Anyone born in the Digital World" is a Digimon, and the first episode shows that Akari has Shoutmon's attacks and can Digi-Xros with Lopmon. She also has to ride in the Xros Loader(s) with the other Digimon, or else she'll disintegrate like any other Digimon.
  • Played straight with Lila the Lillymon and Zenjirou, although Lila just wants to be human, and they haven't admitted to liking each other yet. As of the Hunters arc, they are now Happily Married.
• Instant Costume Change: Betsumon is a master of this, and complains when Tagiru and everyone else Betsumon had stolen clothes from pull off a Flung Clothing change back into their original outfits.
• In the Name of the Moon: Whenever someone asks "Who are you," a roll-call usually follows, ending with
  "We are Xros Heart! Engrave It on your Heart!"
  "The Strongest and Bravest in History! 'Voltasaur Team!' KYORYUGER!"
• Invoked Trope: Shoutmon finds a scarf in the Human world that matches the Scarf of Asskicking that mysteriously appeared (and disappeared) In Shinobi Zone.
• It Runs in the Family: Tactimon implies that being a traitor runs in Hangyomon's family, though whether this was a dig at Hangyomon's family itself or at Xros Heart's future habit of turning enemies into allies remains to be seen.
  • Being completely badass carries on from Xros Heart to the Kyoryuger team.
• Jumped at the Call: Taiki did this to save Dorulumon's life, unaware of all the troubles that were about to fall upon his shoulders.
  • Caleb literally jumped onto Gabutyra's head after being handed a Gaburevolver that he was only meant to hold for a few seconds.
• Laser-Guided Amnesia: Airu, at some point before the Hunters arc began, has most of her memories sealed away, resulting in her forgetting some things that she should have known already. When Gumdramon confronts Airu on her actions, this is brought to light.
  • Luckyuro erased her own memories after surviving the Second Impact and being frozen in a stasis pod for an unknown number of years.
• Law of Inverse Recoil: Averted. The Dorulu Cannon has a NASTY recoil, Taiki only ever uses it twice before collapsing in Lake Zone. After awakening Hephaestus' transforming-creative powers, however, Taiki can handle the recoil a lot better.
• Leaning on the Fourth Wall: Shoutmon briefly wonders if he's taking the position of the viewers of a TV series in chapter 29.
• Massive Multiplayer Crossover: By the end of X0VA-12, the story has become this.
• Memento MacGuffin: Shoutmon's Omega shaped Necklace. Doubles as an actual MacGuffin in that it lets him Digivolve into OmegaShoutmon, and is part of a Stable Time Loop put into place by Shoutmon himself by ensuring it winds up in Tactimon and Lilithmon's hands.
• Mook–Face Turn: Dorulumon starts a trend. Hangyomon, Ba'almon, GrandLocomon,BlueMeramon, and now Olegmon and his entire crew have defected from the Empire. In the Seven Swords finale, the whole Bagura Empire sides with Xros Heart briefly to take on DarkKnightmon.
• Mundane Utility: While the Shapeshifting Spell from the original Xros Wars Manga to turn a Digimon into Human Form is normally used for more private use, Sparrowmon uses it to quickly repair her jet engines and rescue Nene from falling in Heaven Zone. Wizardmon uses the same spell to disguise the other Digimon as humans when the Xros Loaders break down on Earth.
• Mutual Kill: Marcus and Piedmon manage to land a killing blow on each other's hearts in X0VA-5.
• Mythology Gag: The "02" in the title refers to Digimon Adventure 02.
  • The Second arc is named "Seven Swords" instead of "The Evil Seven Death Generals" as a Shout-Out to the rumored title for the Second half of the Xros Wars anime, and gets a Title Drop in the title of the next episode/chapter, 46, "Canyon's Echo! The Seven Swords Forged In the Heart of a Star!" And even in the chapter itself, the Title Drop got a few Title Drops thrown in!
  • In the Rewrite, Zenjirou's floundering in episode 1 is replaced by his line from the Digimon Fusion dub about the "Pit of Screams."
• Nice Job Fixing It, Villain: Dark-Knightmon's plan for making the Darkness Loader was to kidnap Nene, Kiriha, and Taiki, Force-Digi-Xros Kiriha and Nene with his pet-project Shademon, and then feed their Xros Codes to Nene's Sister, Kotone, along with Taiki's Xros Code to create the perfect host for his Ultimate-Shademon and wreak havoc on the Digital World with his Darkness Loader. Too bad that in doing such he ended up waking up the four Guardian Spirits of the Digital World (who had been residing within those four particular humans for all their lives) and caused his entire base to get destroyed. To add insult to injury, Hephaestus and Taiki gave him the smack-down of his life, breaking him down from Dark Knightmon to Skull-Knightmon, and then having him be eaten alive by the guardian Machinedramon hidden underneath his base that he didn't even know was there. Whoops.
  • Quartzmon inadvertently made the friendship between the To-Be-Kyoryugers stronger by awakening the Deboss Legion, giving them something to unite against.
• Noodle Incident: A lot of what happened in Sword Zone falls under this, but the most bizarre example is where Problem learned "The Stare" and turned it on his tormentors.
• Offscreen Moment of Awesome: In X0VA-3, MegaGargomon activates an Emerald Mode parallel to Gallantmon's Crimson Mode. All we hear is the name call, and three minutes later, he's rescued Jeri from the D-Reaper somehow. We're promised that we'll see this event in another story of the authors.
• One-Hit Kill: Played straight at the end of the Karaoke Zone endings, where Gurren Lagann Xros Five Galaxy Drill Breaks Shogun-Gekomon before he even gets a chance to fight. Subverted in the fight against Zamielmon, which was anything but a OHK. It took three repeat firings of the same attack to finally finish him off.
• Play-Along Prisoner: Xros Heart does this to break out the prisoners in Magma Zone.
• Poor Communication Kills: Shoutmon and Akari seem to have some troubles with this during the Hunters Arc- resulting in an apparent six-month long break up that's resolved a single episode after their troubles are fully introduced. Although, it's hinted that part of their troubles behind this is the result of Akari not being able to get pregnant.
• Psychic Dreams for Everyone: The first chapter opens with everyone who was sleeping at the time having the same dream-battle.
• Punctuated! For! Emphasis!: done on multiple occasions, but done rather hilariously in the Kyoryuger Adaptation.
  Do. Not. EVER. Put. The. Kentro. Spiker. Battery. Into. The. Gaburevolver!
• Purely Aesthetic Gender: Averted like it is in the main series, with a few added details. The Shapeshifting Spell from the original Xros Wars Manga to turn a Digimon into Human Form is normally used between Digimon who can't reproduce in their Digimon forms.
• Ragtag Bunch of Misfits: Dust Zone's rebellion force is this. Dorulumon and Shoutmon discuss all of Xros Heart being this in Chapter 36, and Rina makes a call back to it in X0VA-4.
• Rewrite: The Author has made mention several times of the potential of rewriting the earlier chapters to bring the story's initial plot back into line with the rest of it and to remove some Early-Installment Weirdness, and now that it has been completed, the rewrite has begun!
• Rule of Three
• Running Gag: The Red Pickmon and Birds, The Xros Loaders breaking at inconvenient times, everyone falling from the sky when entering a new world area, and the Digimon Introduction Corner Segments. A more subtle one is a character noting if Akari found out that they did something, or failed to do something, she'd kill them. A more frequent one is that when asked "Who are you?", Akari and Shoutmon go into variations of a Roll Call and a "Super Sentai" Stance; but when Taiki tries this one by himself in the Hunters Arc, it's interrupted by Breakdramon going berserk and throwing him off.
• Sanity Slippage: Noboyuki, Sugou, in a nutshell.
• Shout-Out: It has it's own page.
• Spanner in the Works: The Denizens awakening puts a Spanner into DarkKnightmon's plans.
• Spell My Name With An S: Gureimon instead of the usual Greymon, which helps considering that ShineGreymon along with VictoryGreymon, KaiserGreymon, and WarGreymon makes several appearances.
• Stable Time Loop: The whole story so far seems to be the result of many separate loops woven together into a single cloth. One Major loop is that Tactimon left a necklace that was worn by a girl (suspected to be a younger Lilithmon) who rescued Shoutmon from a village being attacked by the Bagura Empire when he was a child. Said necklace then wound up in Shoutmon's possession right when he needed it the most, unlocking his ability to transform into OmegaShoutmon.
• Stealth Pun: the "Miyakuru" at the opening of the second episode is pronounced as "Miracle."
  • In Chapter 67 of XWAU02, when the song ''Black'' plays, a ''Shooter'' named ''Rock'' appears.
  • In the 10th Chapter of the Kyoryuger Adaptation, Fam, a Sky Pirate in her original universe, steals Dogold's battle style as Kyoryu Gold, pilot of the Flying Voltasaur, Pteragordon.
• Stuff Blowing Up: Happens to just about everything that could explode. Including, but not limited too, the Earth.
  • The Kyoryuger adaptation has a Monster of the Week blowing up pretty much once an episode, sometimes multiple times. (And that's not counting the resurrections either.)
• "Super Sentai" Stance: It seems that PawnChessmon Squads are prone to doing this, usually following the In the Name of the Moon roll call.
  • The Kyoryugers do this as a staple of being a Sentai Team.
• Tangled Family Tree: ChibiKamemon calls Akari "Akari-onee-chan", Shoutmon "Shout-onii-san", and Knightmon "Knight-otou-san", despite the fact that he's not related to any of them, and that he considers Knightmon to be more of an uncle than a father, but thinks it sounds better. Akari's mother (Chou) is the cousin of Lilithmon (Airu). In the rewrite, due to Petsula being Lilithmon's daughter, Petsula and Akari are now cousins. Then there's their respective daughters, Kurei and Kuuko...
• Temporal Mutability: The story is all over the scale. Up until the end of Cascade Side B, every time loop fell directly under the You Already Changed the Past trope. After that, however, baring a few minor loops that have had their ends already fulfilled, time travel became inherently more unstable, to the point that if there was a Quartzmon Tower that prevented the Timeline from branching, whatever changes were made would overwrite the future that had been left. As seen from X0VA-1, which introduced the concept similarly to Back to the Future. This odd way of changing things has lead to the events of XOVA's 7 and 9, which take place within a doomed timeline.
• Theme Music Power-Up: Dondokomon's assembled band playing X4B THE GUARDIAN! and SKY DANCING HERO XROS FIVE! in Heaven Zone counts as this. They continue on after this point, playing music whenever the situation calls for it. Eventually, we get We Are Xros Heart Ver X7 sung live as Xros Heart puts together Victory King Time Seven for the first time.
• Theme Naming: The Seven Swords arc has the first half of the episode title being named after the current Land in some way.
• There Is No Kill Like Overkill: Kiriha's motto when it comes to fights. Xros Heart seems to have adopted this in their later fights.
  • Xros Heart Digi-Xrosses two 'PLANETS' together just to turn DarkKnightmon into a sun.
  • Invoked Trope: The United Xros Heart Army says it right before Shoutmon De-Xros destroys NeoVamdemon with three consecutive attacks. In X0VA-4, this comes up once more, with the "GIGA INFINITELY COMBINING RAINBOW EXPLOSION!"
• Time Skip: Twice over the span of three chapters- A day between the Karaoke Zone sing offs end and the final battle in Sword Zone, and a week between Xros Heart's arrival on earth and their return to the Digital World. Six Months have passed for the Digital World from the Battle in Sword Zone to the present day in Dragon Land. A Year has passed since the end of the Seven Swords arc and the start of the Hunters arc. Three months pass between that and X0VA-2, and another two years have passed by the time you get to X0VA-4. Between the end of X0VA-12 and the start of the Kyoryuger sequel, there's been a hybrid skip of eight years for Aincrad and fourteen years for the Digital World/Earth solar system!
• Timey-Wimey Ball: The Time-Static-Storm-Like-Things that keep popping up seem to be a part of one going across all of time and space.
• Troubled Backstory Flashback: Akari and Taiki get these early on, showing how they came to hold the Red Xros Loader and Memento-Goggles, respectively. Sparrowmon get's a series of flashbacks over the first half of Chapter 39. Shoutmon later gets one where he explains how he came to live in Green Zone.
• Unexplained Recovery: SkullKnightmon's survival of being eaten and Giga-Drill-Break'd goes largely unexplained, although it's been theorized by Xros Heart that he's much like the Shademon that he used to possess Nene and Kiriha (and several people in Heaven Zone) and that his data was unstable enough to survive. DarkKnightmon writes a journal entry in a recent chapter trying to explain away his recovery as a survival mechanism. It's up to you if you want to believe him or not.
  • In the Kyoryuger Adaptation, Quartzmon just brings people back to life if he feels like it.
• Virtual Soundtrack: *cue We Are Xros Heart*
• Wham Episode: DarkKnightmon kidnaps Nene, Kiriha, and Taiki as well as cements his status as the first half of the series' Big Bad in Jungle Zone's last episode. Followed by the Dust Zone Arc.
  • The Hunters Finale "Xros Out! Quartzmon's Symphony" has Ryouma revealed as Gravimon, Taiki shot and about to regenerate, and Quartzmon's Apocalypse How scenario coming to full fruition.
  • X0VA-5 changes tone rather suddenly with Marcus' death.
• Wham Line: In Episode 2: Shoutmon asks if Zenjirou "actually thinks there’s a way back” to earth.
  • In the second episode of Hunters, Shoutmon tells Tagiru that he's going to be a father.
  • In X0VA-7, Yuu tells Shoutmon and Akari that they're trapped within a doomed Eva-Verse timeline.
• Whole-Plot Reference: Several that also serve as Shout outs.
• Who's on First?: Lila and Nene's nonsense routine that finally gets Karatenmon to laugh appears to be a failed attempt at this.
• Xros Over: Much like canon Hunters, alternate versions of various heroes from other Digital Worlds appear to help fight Quartzmon's Towers, and the first five X0VAs are cross overs between Digimon Xros Wars and the previous Digimon series.
  • Yuu is hinted to be going to Aincrad in the future to fight "The Skull Reaper," the floor 75 boss. This is confirmed with a scene in "Cascade Side B" showing Kirito facing off against The Gleam Eyes, the floor 74 boss, and the later X0VA-6, where this Xros Over actually begins.
  • Rei from Nobody Dies has appeared at some point during her inter-dimensional journey. She and Unit 05 appear once more during the "Cascade Side B" sequence, and she appears as a recurring character from X0VA-7 on.
• You ALL Share My Story: DarkKnightmon wonders on the fact that Taiki, Kiriha, Nene, and her sister all have extremely Strong Xros Codes despite not being born in the Digital World. It's later revealed that their parents were all former heroes who saved the Digital World, and that the Denizens gave their very power and essences to them in order to defeat Moon Milleniumnmon. Sparrowmon is included in this too, as her parents were a part of that group as well.
• Your Size May Vary: It's a brief blink and you miss it line, but Sparrowmon had data that allows Xros Five (and any subsequent forms) to adjust their size to match their opponent. This is used against Giga-Breakdramon's Gravity Press attack by shrinking down to half their original size and negating the original attack's parameters.
  • Thanks to the Carnival Beast Battery, the Voltasaurs can shift between chibi versions of themselves and their usual towering forms.
