* ActorAllusion: The [[http://www.animenewsnetwork.com/news/2012-07-20/eureka-seven-ao-hybrid-game/anime-promo-streamed trailer]] of the {{OVA}}/{{LicensedGame}} hybrid disc shows Elena in an outfit and pose similar to [[SoulEater Maka's]]. As indicated below, both share a voice actor.
** She also says Maka's catchphrase as well.
* AnimeFirst: Technically the manga was released first, but it's meant as an advertisement for the anime and was overtaken by it in only a couple episodes (the manga being released on a monthly basis with about the same amount of content per release), so the story is anime first.
* CastingGag: The casting of MicahSolusod as JohnnyYongBosch's son, especially given the mistaken identity between the two when ''SoulEater'' first came about.
* HeyItsThatVoice:
** [[Creator/KazuhikoInoue You don't deserve]] to know [[MachineRobo Truth's name]]!
** [[Creator/ChieNakamura Rebecka]] is [[{{Naruto}} Sakura]]
** [[ChiakiOmigawa Elena]] is [[SoulEater Maka]]
** [[HidenobuKiuchi Georg]] is [[Manga/{{Monster}} Dr. Tenma]]
** Truth's female form [[http://www.animenewsnetwork.com/encyclopedia/people.php?id=1376 is voiced by]] Creator/SayakaOhara. [[UminekoNoNakuKoroNi Pity she's not red.]]
** [[Creator/KeijiFujiwara Renton]] is Holland.
** In the English dub we have;
*** MicahSolusod as Ao. Who funnily enough sounds like JohnnyYongBosch who voiced [[EurekaSeven Renton]].
*** JamieMarchi as Rebecka
*** Creator/ToddHaberkorn as Truth
*** Creator/MonicaRial as Noa
**** RoleReprisal: Both Creator/StephanieSheh and Creator/JohnnyYongBosch reprise their roles as Eureka and Renton respectively from the previous series.
* NamesTheSame: The song for the second OP is titled "VideoGame/BlazBlue".
* RealitySubtext: Episode 8 has interference from the Americans due to it being election season. At the time it was broadcast, the American 2012 elections were only six months away.
* ScheduleSlip: The series skipped airing for a week in June due to a soccer game, and skipped the first two weeks in August due to the 2012 OlympicGames. Because of the delays, the last two episodes aired on November 19, since ''Manga/ZetsuenNoTempest'' took over the show's timeslot in October.
* WhatCouldHaveBeen: Allegedly, the series' original writer backed out of the project after only writing the first two episodes, forcing the crew to write up an entirely new plot.
** Supposedly, Naru was going to be a member of Pied Piper. Which explains a lot about the original opening, really.
** There is some circumstantial evidence to indicate that [[spoiler: The[=END=], Elena Peoples, and Ao's sister]] weren't going to be the {{Red Herring}}s [[WriterCopOut that they were in the series]]. Particularly egregious in [[spoiler:Elena's case]], given the [[PurpleEyes visual]] [[TraitorShot evidence]] and outright {{foreshadowing}} that she was more than human.
* WriterRevolt: It's not an outright revolt but Kenichi Yoshida, character designer and animator for both this anime and the original ''Anime/EurekaSeven'', drew [[http://gallo44gallery.web.fc2.com/ao_girigir_001.html a series of pictures]] where original series character [[EnsembleDarkhorse Anemone]] complains about her [[ChuckCunninghamSyndrome non-inclusion]] in this show. Including one where she [[HostileShowTakeover redraws the animation storyboards]].
-->'''Anemone''': Hey! Don't you think you have a bit too much screen time? Give me some of that too!
-->'''Eureka''': Whaaat? But what can I do?
-->'''Anemone''': Get your boy to fire that cannon and change it to a world with me in it!
** On a related note, ''[[{{Yonkoma}} Eureka Seven nAnO]]'' has a panel of Elena watching Anemone on television while saying "[[RecursiveCanon This season got many good shows]]". It seems the manga artist wanted to see Anemone too.
