History Fanfic / DestinysDivide

* LiteralSpitPersonality: Chapter 18 sees the formation of Vezon off of Vezok.

* PowerNullifier: During the fight with the future Piraka, Penny uses her Semblance on Thok to disable his ability to create prisons with his mind.

* FlawedPrototype: Salem's initial batch of rideable Grimm is meticulously conditioned to follow the Skrall's commands--an achievement that impresses Tuma, even if he won't admit it. However, when Tuma orders the Grimm to fight him, he swiftly dispatches it, revealing its flaws. The creature's sluggishness and excessive armor-plating on the rear make it vulnerable to attacks from the front. In response, Tuma advises Salem to enhance the next batch by increasing speed and reinforcing the front armor, while allowing the rider to protect the rear.

* FellOffTheBackOfATruck: Berix claims that this his how he got his seemingly-endless supply of macarons - from a crate that fell off a caravan vehicle, and he simply couldn't let all that food go to waste. Emerald isn't convinced, but doesn't press the issue.
* FigureItOutYourself: Emerald notes that Salem always took this approach with Cinder in regards to her Maiden powers, just telling her what to do and expecting her to figure out ''how'' herself.
* FlawedPrototype: Salem's first batch of the rideable Grimm are conditioned to obey the commands of the Skrall, something that impresses Tuma even if he won't admit it. However, when Tuma commands it to fight him and he easily kills it, he demonstrates that the Grimm is too small and cumbersome and it has too much armor-plating on the back and not enough on the front, exposing weak points that the enemy can hit. Tuma instructs Salem to make the next batch faster and put armor-plating on the front while letting the rider defend the rear.

** Despite the fact that they're all on the same side, the representatives of Vacuo and Atlas ''do not'' get along with each other, as seen during the Council meeting in Chapter 10. [[ShamingTheMob Yang puts her foot down once she's had enough.]]

* OriginalCharacter: Petra Zephyr, the seven-year-old daughter of Headmaster Theodore, plays the part of the (as-yet-unknown in canon) Summer Maiden. She's spunky and rambunctious, but doesn't have any idea how to use her powers - and even her Aura refuses to activate, which just baffles and frustrates the main cast.

* NoBodyLeftBehind: When the Skrall are first shown fighting the Creatures of Grimm, Tuma shows annoyance at the fact that their bodies disappear into mist as soon as they're killed, since he wanted to collect a BattleTrophy from the beasts of Remnant.

* BookEnds: A minor example in Chapter 14, "Legacy of the Schnees." It begins with Whitley having a verbal (and almost physical) altercation with a Vacuan Huntsman, and ends with Whitley [[spoiler:personally delivering a crate of Dustfruits]] to that same Huntsman.

The first fic, ''[[https://archiveofourown.org/works/36718834/ Destiny's Divide]]'' [[note]][[https://www.fanfiction.net/s/14029847/1/Destiny-s-Divide FanFiction.Net link]] [[/note]], opens with Team RWBY fighting with Cinder in the space Ambrosius created to evacuate the people of Atlas to Vacuo, but this time things go somewhat differently and Emerald ends up joining our heroines (and Neo) on their plunge instead of Jaune. They then fall out of the void... into the skies over the island of Mata Nui as the Toa are arriving, and find themselves trying to help these new heroes defeat yet another force of ancient darkness and malevolence. In addition to the girls navigating the island and their own trauma, a newly-human Penny Polendina [[BackFromTheDead gets another chance at life...]][[CantLiveWithoutYou though it's contingent on constantly being near]] Takua, a strange little Matoran [[AmnesiacHero with no idea of anything besides his own name]]. It began on January 28th, 2022, and was completed on March 28th, 2023.

* DeathByAdaptation: Sort of, while Cardin simply [[WhatHappenedToTheMouse disappears after vol. 3]], in ch. 15 Yang acknowledges him as MIA.

* GoodOldFisticuffs:
** Much like in canon, this is Yang's preferred fighting style, complete with [[MixAndMatchWeapon shotgun gauntlets.]] Once he acquires the Mask of Strength (and after a little bit of coaching), Tahu comes to adopt this against enemies that resist fire.
** Onua is no slouch in this department either, if his fight against an Infected Lewa is anything to go by, though he seems to prefer clever thinking and elemental powers over a full-on slugfest.

* HumansAreUgly: On more than one occasion the Matoran, and to a lesser extent the Toa, are weirded and grossed out by the biology of the Huntresses. Takua in particular finds Penny's toes ''extremely'' repulsive, comparing them to worms stuck to her feet, among other things. In fact, part of the reason Makuta decides against trying to expose the Huntresses to Energized Protodermis in their fight is not wanting to see if it would make them look even ''worse''.

* PaintingTheMedium: Beings of great power relative to the Toa and Huntresses (such as Makuta, the Toa Kaita, and [[spoiler:Mata Nui himself]]) almost exclusively have their dialogue portrayed in italics to represent how PowerEchoes.

* TeamChef: Yang serves this role whenever the girls are together. She spends most of the story working out how to make the metallic food of Mata Nui more palatable for human taste, which is definitely appreciated by her non-Matoran companions. Neopolitan and Penny in particular appreciate her cooking.

* AdaptationalBadass: The Boxor machines in this AU have a laser Nuparu and Penny designed added to them, giving them a ranged attack.

* PuppeteerParasite: The Krana as in canon, which is made worse by how they can produce tentacles to help them move around, and made worse by the possibility that, since they're organic, they might be able to work on the Remnantians as well.

* TakeMeToYourLeader: Lampshaded by Fox (see above), then played straight when the Agori agree to form and send a FirstContact party to the city of Vacuo.

* WeAreStrugglingTogether: One of the major conflicts the heroes face on the Remnant side of things, as it's clear that Atlesians and Vacuans ''still'' struggle to get along and find common ground. This is most evident in the opening chapter (where Ruby and friends have to fight off a Grimm attack sparked by a riot breaking out in the Glass District, and where Joanna and Harriet are still at each other's throats) and during the Vacuo City Council scene in Chapter 10. By the latter, Yang's seen this happen enough times that she's completely sick of it.

* AdaptationalEarlyAppearance: The Piraka, still with the Dark Hunters, attack Axonn and Penny on Xia, well before the timeframe of the Voya Nui arc.

* BeatThemAtTheirOwnGame: When she and Axonn are at Roodaka's shop looking for some of the parts that they need to repair Metru Nui, the Vortixx refuses to accept Axonn's payment, since the last time he was there he paid with the Spear of Fusion from Teridax's lair. Penny manages to get her to give them the parts by throwing in a few inches of her hair, telling Roodaka the truth of its origins in a somewhat dramatic fashion, but ''not'' that it grows back, conning her (and getting Axonn to smile in the process). Considering that a few minutes before Roodaka was boasting about how the Vortixx have known about the Order since pretty much the beginning, and that her people are masters of deception and uncovering secrets, Penny definitely beat her at her favorite game.

* FantasticFruitsAndVegetables: The "Dustfruit" plants that Whitley manages to make from the Vuata Maca seed pod brought back to Remnant from the last story not only share the Aura-replenishment properties of their progenitor plant, but can act as renewable sources of Dust. It tastes a lot better than the original too.

* HorseOfADifferentColor: One of the things that Tuma gets out of his alliance with Salem is a new breed of Grimm that he and his warriors can ride.

* KeepingSecretsSucks: When Kopaka calls Nokama out for how she and the other Turaga are keeping secrets, she makes it clear that they don't ''like'' having to do so, but feel that they have to.

* MamaBear: Mumu very clearly loves her kittens, to the point that she remains in her den, despite the Bohrok in the area, because her kittens are too young to survive the cold of the blizzard outside.

* MultipurposeMonoculturedCrop: Upon experimenting with the Vuata Maca seed pod that was brought back from Mata Nui in Chapter 14, Whitley finds that the seeds can be infused with Dust to create what he calls "Dustfruit" plants, growing quickly with Aura. The resulting plants are a plentiful food source that replenishes Aura, can be used as a renewable source of Dust for weapons and other uses, and the ones made with Water dust allow for fresh water to be constantly available in the Vacuo desert.

* OOCIsSeriousBusiness:
** Vakama notes that [[spoiler:Makuta summoning the Kanohi Dragon]] is a complete surprise, given how the Makuta had previously limited himself to the Rahi on the island, showing the Turaga just how much their foe instinctively ''fears'' the Huntresses and their ability to be a SpannerInTheWorks for his plans. [[{{Pride}} Not that the Master of Shadows would ever admit his fear, however.]]
** On the boat ride to save Ga-Koro, Penny finds Ruby's sudden HeroicBSOD after the motor breaks ''extremely'' disquieting. Granted, the poor girl had every reason to be upset, considering she's blaming herself for almost everything that's gone wrong in the last few days. On both worlds.
