History Anime / DarlingInTheFranxx

* YouAreNumberSix: Only Zero Two is known by her numbered designation while the rest of the children have actual names. And even those are only a very small step above this trope, as they are based on alternative readings of their respective numbers (invented by Hiro).

* DoesThisRemindYouOfAnything: The act of piloting a Franxx is a pretty clear parallel to sex, what with the positions of the pilots, and Hiro's inability to pilot one in most situations is treated as if he has a case of TheLoinsSleepTonight, complete with him attempting to motivate himself to pilot by kissing his copilot. Another character even explicitly tells her stamen to "Get it up!" at one point when they can't move their Franxx.
* ADogNamedDog: All the children's names, with Zero Two as the exception, are just [[GoroawaseNumber alternative readings]] of their [[YouAreNumberSix designations]].

* GoroawaseNumber: The children's "names" derive from their numerical designations.

* PhlebotinumHandlingRequirements: Franxx cannot be piloted by just any pair - the duo, aside from being opposite genders with good mental sync, must also be naturally compatible.

* WhamShot:[[spoiler: At the end of episode three, we see Mitsuru bleeding and injured in the cockpit of Strelizia, revealing that the rumors surrounding Zero Two's partners being unable to ride with her more than three times before dying are true.]]
* YouAreNumberSix: Only Zero Two is known by her numbered designation while the rest of the children have actual names. And even those are only a very small step above this trope, as they are based on alternative readings of their respective numbers.

* BeachEpisode: Episode 7.

* TheOmniScientCouncilOfVagueness: The leaders of APE sit in a circle and only talk about how the main cast are an experimental team.

* WellDoneSonGuy: All of the parasites are raised with Papa, the head of APE, as a distant surrogate father figure that they are trying to impress. Zorome fully buys into this while others are less enthusiastic.

** Bears: Relatedly, the klaxosaurs are giant beasts trying to steal the plantations magma like bears do to honey bee hives. Zero Two, being part klaxosaur, also seems to have a fondness for covering her food in either honey or syrup.

** Bees: The Plantations' society is divided into strict societal roles, with Papa and the other adults acting like queen bees while the parasites act as soldiers defending the hive/plantation. Their tech and power is fueled by magma, which is colored a honey gold color. The interior city of the plantation is all golden buildings. Gold hexagonal shapes like honeycomb are frequently used, in in interior hallways, in the mission control computer screens, even the HUDs of the Franxx. It also ties into the parasites' designation as stamens and pistils, and all the Franxx being [[{{FloralThemeNaming}} named after flowers.]]

* AnimalMotifs: The young parasites are compared to nestlings huddled together in their dark nest dreaming of one day being able to see the sky; the cooperation between male and female pilots operating Franxx is compared to a myth of a species of bird where males and females have only one wing and thus can only fly together; and parasites who are unable to pilot are compared to birds unable to fly, doomed to an early death because, "where would a flightless bird go?"

** ''Everyone'' of the boys in episode 8, much to [[{{Troll}} Zero Two]]'s amusement.

* WashtubThrow: In Episode 8, the girls sans Zero Two do this when the boys enter the bath after thinking it was unoccupied courtesy of Zero Two pulling a prank on them.

* ThisIsMySide: The eight episode has the girls dividing the house in half after an argument with the boys.

* SpentShellsShower: Downplayed; when Strelizia kills the klaxsaur with her weapon, a single shell is ejected into the air and falls onto the ground with a heavy thud.

* LoveDodecahedron:By episode 7, the series' relationships are becoming quite the headache. Goro and [[AmbiguouslyGay possibly Ikuno]] have feelings for Ichigo, who loves Hiro, who loves Zero Two, who reciprocates, while [[{{Tsundere}} Miku and Zorome]] may have unadmitted feelings for each other. What makes it a headache is that outside of Zero Two these kids have about zero understanding of romantic feelings and relationships due to their upbringing.

* SuperRobot: ''Anime/DarlingInTheFranxx'' is clearly one of these, where one robot is clearly better than the rest, and HotBlooded willpower matters most.
