* {{Adorkable}}:
** Renton's awkward and blushing around those he admires, and is nonetheless adorable despite it.
** Dominic's serious and blunt about his work, but is just ''adorable'' when he's lost or if he's looking dreamily at Anemone.
* ArcFatigue: The Mine Arc, where the crew is trying to repair the Gekko, which ranges from roughly Episodes 15-20. Most of the episodes include a lot of {{Angst}} on the parts of Renton and Eureka and Holland's abusive behavior towards Renton reaches its upper limits. Fortunately, the Charles and Ray Arc begins almost directly after, which is where the series begins to pick up in steam again, which it manages to maintain for the remainder of the plot.
* BaseBreakingCharacter:
** Holland is the biggest example, as the fanbase is pretty evenly split on whether he effectively redeems himself in the second half of the series for his abusive {{Jerkass}} behavior in the first half [[NeverLiveItDown or not.]]
** Talho. Some find her irritating, which was not helped by her actions in episode 4 where she worked Renton like a housemaid and punished him for a financial outcome he had no control over. However, some give her slack for being the only member of the Gekkostate who is willing to call Holland out on his JerkAss behavior.
** Renton himself in the early episodes. Viewers will either see him as TheWoobie and a likable, engaging lead character, or a {{Wangst}}y brat who surpasses [[Anime/NeonGenesisEvangelion Shinji Ikari]] in being a depressive wuss who has no business being in the line of work he's in.
** Dewey. Many see him as he was intended, a HateSink with ambition up the wazoo that gets scores of innocents killed for stupid reasons, [[spoiler: himself included]]. However, with the dark developments in sequel ''Eureka Seven: AO'', Dewey's actions in hindsight look far more like those of a WellIntentionedExtremist... but still unforgivable nonetheless.
* BrokenBase: Fan reaction to ''Hi-Evolution 1'' has been sketchy. There are a lot of people upset to see some characters cut from the apparent reboot and some steep changes that mess with the original story, and many who were salty when it became known that only around the first 30 minutes of the film and the last few minutes were new animation and material and the rest was just a repackaging of the original series around the second season. As for ''Hi-Evolution 2'', people are wondering what in the world is going on with the story because the promos are darting in all different directions and suggesting a new universe, the old one, the reboot, and a weird soccer match between the mecha across all the various series incarnations.
* CompleteMonster: [[FauxAffablyEvil Dewey Novak]] put his top fighter Anemone and [[WouldHurtAChild multiple girls like her]] through torturous experiments to make them TykeBomb soldiers. Anemone was the only survivor, but [[MindRape her mind was severely damaged]]. In order to gain support for his war efforts, Dewey engineers enormous levels of civilian casualties, using the Coralians as a scapegoat to convince humanity they cannot coexist and must wipe out the Coralians. His motivation is that his world domination plans [[FantasticRacism have no place for the Coralians]]. He is also motivated by a petty grudge with his [[spoiler:younger brother Holland]], and he even prepared to destroy the universe should he fail.
* DesignatedMonkey: A common complaint about the early episodes was for doing nothing but make Renton's life hell, as everybody at the Gekkostate (apart from Eureka) is a massive prick to him. Episode 4 shows it at its worst since it ends with Renton getting punished for a financial outcome he had no control over.
* EnsembleDarkhorse:
** Charles and Ray are present for a single arc about mid-stream of the series but they get a lot of fan love for treating Renton with respect (they all but ''adopt'' him), and for being extremely sympathetic [[AntiVillain Anti-Villains]]. Some wish Renton stayed with them, mostly due to how much of pricks the people at the Gekko could be towards him.
** Moondoggie is one of the more minor members of Gecko State but he has a lot of fans. Part of this is for his attractive design, and partially for his growth and character development.
** The trio of girls who show up to Axel's workshop and can be seen in Renton's class; their designs are unusually well thought out, even for background characters. If only we knew their names.
** From the prequel video games/''Gravity Boys & Lifting Girl'', Gillian's popularity among readers is noted to have skyrocketed after her DayInTheLimelight.
* EveryoneIsJesusInPurgatory: Played with in the soccer episode. Norb says they should play soccer and several people ponder why they're playing soccer. At the end, Norb says something along the lines of "If you had fun, that's good. If you learned something, that's good too."
* FanNickname: Renton and Eureka are respectively nicknamed "[=RenTears=]" and "[=EuWrecka=]" whenever they get overly emotional.
* FanonDiscontinuity: Long story short, ''everything'' released after the original series get this treatment from the fandom.
** Even though (or perhaps because) the movie takes place in an AlternateUniverse, many fans refuse to acknowledge the movie's existence. Previously popular characters like Dominick and Anemone [[DroppedABridgeOnHim getting bridges dropped on them]] or [[PutOnABus just plain not showing up]], and throwing out some of the themes that defined the original series were also factors that contributed to fans refusing to accept the film.
** Just to illustrate the level of rejection, a common nickname for the movie in the Russian fandom is literally "The pocket full of shit", mocking its Japanese title "The Pocket Full Of Rainbows".
** A lot of fans have [[ContestedSequel much the same reaction]] to Anime/EurekaSevenAO for the exact same reason.
** The film trilogy being another AlternateContinuity, instead of what was thought to be a CompressedAdaptation with new scenes that still follow the canon of the original series, has killed some fans' excitement for it. The second film of the bunch seems to have a mixed reaction with fans wondering if they should even try to make sense of the timelines anymore because the promos are all over the place and somehow the film includes all the franchise's mecha... in a ''soccer match''. The second film ending with seemingly killing off [[spoiler: Renton and making many controversial decisions with how to include the rest of the franchise in its narrative, making it seem as if all of them are just delusions of Eureka's.]] Naturally, the fans who found this out were quick to the drop the ''Hi-Evolution'' films and had low expectations for the third film. Some fans even resorted to penning fanfiction so they could pave over the offending canon.
* FirstInstallmentWins: The anime is highly regarded compared to any of the other entries that came afterwards. This is largely because of changes to the series that haven't gone too well for the fans.
* GrowingTheBeard: Starts off inauspicious and mean-spirited, starts picking up once the Beams are introduced, picks up even more after [[SugarWiki/HeartwarmingMoments Episode 26]], and ''explodes'' several episodes later.
* HarsherInHindsight: Ray's anger towards Eureka, for being sterile because of the Seven Swell, and can't have children of her own. This stings a lot more when you realize that in the [[Anime/EurekaSevenAo sequel series]], [[spoiler: Eureka can't have children in that world without them dying, her firstborn child dies shortly after birth, and she wasn't able to raise Ao for most of his life. They were ''both'' robbed of their chances at (natural) motherhood.]] This is one of the reasons it's the ContestedSequel and a frequent FanonDiscontinuity.
** Mattheiu callously asking if Renton's mother taught him any manners in an early episode. [[DeathByChildbirth Gravestones can't do much talking at all.]]
* JerkassWoobie:
** Anemone, whose belligerent attitude hides a horrific backstory and set of circumstances. By the end of her arc, the other characters are trying to help her, rather than fight her.
** As much of a {{Jerkass}} Holland is, his past clearly haunts him, and the world seems to have it out for him, such as nearly killing him on a regular basis. Some of the later episodes are especially harsh to him, especially in the penultimate episode where [[spoiler:he has to watch his older brother blow his own head off right in front of him.]]
** The Ageha Squad. Five [[CreepyChild young girls]], all survivors of an ethnic cleansing and heavily suggested abuse at the hands of the military, who've been groomed, brainwashed and raised as child soldiers by Dewey and maintain UndyingLoyalty to him because [[BecauseYouWereNiceToMe he showed them kindness]] as means of [[ManipulativeBastard manipulating them]]. Making them extra jerkish ''and'' extra pitiable is that their jealousy and hatred directed towards Anemone is based on things that apply to them as well but they're never able to recognize it.
%%% "Enough said." is never sufficient.
* MemeticMutation:
** The re-airing of the series on Creator/{{Toonami}} has created a minor meme in the forums of [[Website/TVTropes this wiki]]: "Renton Thurston, fourteen years old!" or "It's time for 'Sucky Life Of 14-Year-Old Boy'!"
** ''Eureka Seven'' is an anagram for Creator/KeanuReeves
** Nijiura Seven, where the second OP and Renton Thurston's funny face being held by the collar by Holland ended up as meme in Website/NicoNicoDouga.
* MoralEventHorizon: [[spoiler:Movie!Hap and Movie!Stoner hold down Eureka and rip her top open.]] What makes this worse is their apparent motivation for doing so--they were concerned about their reenactment of a myth (you know, those typically orally passed down and ''allegorical'' stories) not following the story to the letter.
* {{Narm}}:
** Episode 6. The kids crying over not wanting to lose their mother [[AgeAppropriateAngst may be appropriate for their ages,]] but it's so overdone especially in comparison to Renton's ordeals that it's hard to take the scene seriously. They apologize to him later, combined with the context and [[SugarWiki/AwesomeMusic beautiful violins playing in the background ]] does redeem it a bit.
** In "Paradise Lost", Renton struggles with the idea of [[spoiler:addressing Ray and Charles as his mother and father]]. ...''anyway''...
--->'''Charles:''' ''(embraces Renton, shoving his face into his own chest)'' "I worked up a sweat at the gym just now. Do I smell bad?"\\
''(Renton looks up at Charles and shakes his head)''\\
'''Charles:''' "This is how your [[spoiler:dad]] smells."\\
'''Renton:''' ''(tearfully)'' "It really is a good smell..."
*** A few minutes later, [[http://i.imgur.com/3g7YD.jpg Ray makes this face]] when she finds out who Renton's father is.
*** In "Wish Upon a Star", Renton grabs a flower that (presumably symbolically? [[GainaxEnding The ending is a bit strange]]) appears in Nirvash's cockpit. As he does, there's a "ding!" sound effect like he just picked up a video game powerup.
** The Silver Box in ''Hi-Evolution'' was a musical weapon to use on the Command Cluster and looked more like a rave party than a superweapon. It also is noted a problem arose because acid jazz failed to sync and the device soon accidentally razed the planet it was meant to save. Acid jazz helped partially doom the planet.
* NarmCharm: The series practically runs on this. The colors are [[DesignStudentsOrgasm blindingly bright]], the music is sugar-sweet, the idealism is [[WideEyedIdealist almost offensive]], and love ''always'' [[ThePowerOfLove conquers all]]--and then the series finale ramps it up even further...and by some insane miracle, for many it ''works''.
** Even the extremely silly and hammy Charles and Ray still work in context [[spoiler: given by the time Renton meets them, he's become a fullblown EmoTeen and they're the first people to treat him kindly in years]], turning the Narm into a Heartwarmer.
* NeverLiveItDown: Okay, Holland is [[{{Jerkass}} a total prick]] to Renton in the first half of the series. Some people seem to forget that [[CharacterDevelopment he grows out of it]] in the latter half and claim he remains an insufferable douchebag throughout. This attitude seemingly stems from the fact quite a few people would regard physically [[WouldHurtAChild assaulting a child]] just ''once'' hard enough to live down. Holland attacks Renton on ''multiple'' occasions.
* OlderThanTheyThink: The iconic insert songs "Storywriter" and "Niji" were released before the show in 2002 and 1994, respectively. "Niji" was especially a hit with Japanese and European techno fans, and it being used over a decade later as the finale's ClimacticMusic speaks for how timeless the song is.
* RescuedFromTheScrappyHeap: Holland's general treatment of Renton during the first half of the series is downright brutal at times. The fact he uses Renton as a punching bag on multiple occasions, basically taking out his own inadequacies on a kid, is enough on its own to be loathed by many fans. By the second half however, he becomes a more likable character thanks to him accepting the fact that Renton is TheChosenOne and also reconciled with the latter.
* RootingForTheEmpire: Holland being ''[[RonTheDeathEater the]]'' biggest BaseBreakingCharacter in the series [[NeverLiveItDown his early abusive treatment of Renton]] leading to many viewers actively rooting that Renton would actually stay with Charles and Ray and that they would succeed in their attempt to kill Holland.
* TheScrappy: Those ''Goddamn kids''. Linck in particular. They cry in almost all of their appearances, are completely spoiled, and their continual cries of "Mama!" can become really annoying. Maurice shows his Scrappy colors later on, when they're lost [[spoiler:on Earth]]. "Only love me, mama! No one else!" And then Renton and Eureka just have to go and be so damn ''understanding'' about it.
* TakeThatScrappy:
** Whenever Talho slaps Holland, you can hear the sound of cheering around the world.
** Fans were also impressed when Renton gave Holland a BadassBoast on how he came back to the Gekkostate for Eureka.
* {{Wangst}}: Renton does a lot of griping around half of the first episode because his life isn't as exciting as he would like. Stays in sight for a while before it evolves into genuine {{Angst}} and then disappears.
* TheyWastedAPerfectlyGoodCharacter: Ever wonder what the crew's backstories are that would make them more than just auxillary characters that Renton happens to know?
* TheyWastedAPerfectlyGoodPlot: When Renton finally [[spoiler:reunites with his father, Adroc doesn't say a damn thing.]] This is because the Japanese voice casting crew couldn't find an actor they felt would do his character justice. Because of this, the apparent closure between Renton and [[spoiler: his father]] that needed to be addressed in that episode seems to come off as weaker and inadequate, and it leaves a bitter taste in a lot of viewers' mouths.
** Following the release of ''Hi-Evolution 1'' and ''2'', some fans believe Bones missed a prime opportunity to update the franchise for a new audience. Much of the criticism around ''Hi-Evolution 1'' centers on the opening 30 minutes of the film focusing on the Summer of Love before segueing into an hour-and-a-half-long CompilationMovie when it was widely believed the movie would be a full-blown prequel. Likewise, ''Hi-Evolution 2'' has been heavily criticized for not taking the chance to give Anemone a fleshed out backstory and add depth to her character and her relationship with Dominic and instead [[spoiler: going on a wild, multi-dimensional tangent that renders the story difficult to understand or care about due to veering too heavily on MindScrew and DarkerAndEdgier elements]].
* ViewerPronunciationConfusion: Many people mistakenly think Eureka's name is pronounced "yoo-reeka", but it's actually pronounced Eu-Recca.
* VindicatedByHistory: Downplayed with the [[AlternateUniverse manga]], which was generally well-received but not everyone [[TheyChangedItNowItSucks enjoyed the changes made to the series]], including the BittersweetEnding. However, considering how incredibly divisive the later, other well-known adaptations [[note]]i.e. the films and ''AO''; the video games, other manga series, and light novels are mostly obscure[[/note]] would be, many now see the manga as the only acceptably DarkerAndEdgier installment by remaining true to the spirit of the original series (it is notably one of the few to avoid making anyone an AdaptationalJerkass; a common criticism of other adaptations is characters needlessly becoming villains/unsympathetic).
* WhatDoYouMeanItsForKids: As [[http://www.japansociety.org/resources/content/2/0/5/4/documents/sato_mcgray%20interview.pdf confirmed by the screenwriter Dai Sato]], Eureka Seven aired at 7 AM on Sunday mornings in Japan. The large amount of violence, however, caused the English dub to air [[http://www.siliconera.com/2006/05/30/eureka-seven-is-not-a-hit-in-the-us/ at 1:30 am on Adult Swim.]]
** It is also interesting to note that Studio 23, a channel in the Philippines, [[https://www.youtube.com/watch?v=zPetXxAmqF4 aired the Tagalog dub at 10 AM.]]
** Not to mention that Episode 38 deals with the confusion that Renton was pressuring Eureka into sex ([[NiceGuy which Renton would NEVER do]]), and an earlier episode hinted that Holland had sex with Talho.
** In the DVD commentary for episode 20, even the voice actors were astonished by the show's timeslot (especially with regard to the final scenes of that episode).
* WhatDoYouMeanItsNotSymbolic: The show has references to Buddhist mythology and ''The Golden Bough''.
* TheWoobie: Renton (once he transitions out of being the DesignatedMonkey) and Eureka are both children who go through a ''lot'' in their efforts to save the world, along with grappling with a lot of pressure and understandable insecurity along the way.
