* According to ''Anime/EurekaSeven'', to end existence, all you have to do is [[LogicBomb make too many things think at once...]] thus reaching the limit of questions and causing the universe to overload. Dewey, the BigBad almost succeeds, [[spoiler:by waking up the dormant aliens that have covered the earth's crust]].
** Though this seems to happen only in the anime, where the thoughts have mass (the trapar is made of the dreams of the dormant Coralian crust). In the manga, the limit of questions is never mentioned. The motivations of the Coralians are very different, too.

* HeyItsThatVoice: The English version features the cream of the crop of UsefulNotes/LosAngeles-based anime dubbers, including Creator/JohnnyYongBosch, Creator/StephanieSheh, Creator/CrispinFreeman, Creator/KateHiggins, Creator/KariWahlgren, Creator/MaryElizabethMcGlynn, and Creator/MichaelMcConnohie.
** The Japanese can have this effect as well. Among others, [[Creator/KaoriNazuka Eureka]] is [[Anime/CodeGeass Nunnally]], [[Creator/MichikoNeya Talho]] is [[LightNovel/FullMetalPanic Melissa Mao]] and [[KoujiTsujitani Dewey]] is [[Manga/InuYasha Miroku]]. For ''{{Gundam 00}}'' fans, [[MamoruMiyano Moondoggie]] is Setsuna F. Seiei, [[YasunoriMatsumoto Stoner]] is Alejandro Corner, and they both serve aboard the ''Gekko'' under the command of [[Creator/KeijiFujiwara Ali al-Saachez]]
* HeyItsThatPlace: Fallingwater is the setting for part of an episode.
* MemeticMutation: One scene where Renton's face had gone apeshit insane when grabbed by Holland by the collar had evolved into a video called Nijiura 7.
** [[SignificantAnagram Keanu Reeves]].
* RelationshipVoiceActor: Yet again, Creator/JohnnyYongBosch and Creator/StephanieSheh [[GurrenLagann are]] [[Manga/{{Bleach}} lovers]].
** This isn't the first time Creator/CrispinFreeman has been jealous of [[LightNovel/HaruhiSuzumiya a relationship between characters]] voiced by Sheh and Bosch, nor promised to protect a character voiced by Sheh.
** It might have been the first time that Crispin Freeman's character was really pissed off by Bosch's character, but [[CodeGeass it definitely wouldn't]] [[LightNovel/{{Durarara}} be the last]].
