* FanNickname:
** ''[[Anime/DragonBallGT Saint Seiya GT]]'', both made by Toei Animation, with no input from their original creators, set many years after the original series' ending, not canon to the original universe and with polarizing fan reactions.
** ''[[Anime/YuGiOhGX Saint Seiya GX]]'', both spin-offs of a popular anime, focusing on a younger cast, introducing a [[BrokenBase controversial]] school that teaches each universe's concepts, and also with polarizing fan reactions.
* TheOtherDarrin:
** Shoko Nakagawa is darrining Creator/KeikoHan and Creator/FumikoOrikasa as Saori/Athena.
** Creator/KiyoyukiYanada replaced Yuji Mikimoto as Geki.
** Creator/HiroshiKamiya is replacing Creator/RyoHorikawa as [[spoiler: Andromeda Shun]]
** Creator/ShigeruNakahara darrin'd Creator/HirokoEmori and UmekaShoji as Kiki ([[SheIsAllGrownUp well he's an adult now so it's understandable]])
** Creator/MamoruMiyano replaced Creator/HiroakiMiura and Creator/KoichiHashimoto as [[spoiler:Cygnus Hyoga]].
** Creator/KenNarita replaces the late Creator/HirotakaSuzuoki and Creator/TakahiroSakurai as [[spoiler: Dragon Shiryu]].
** In the Mexican Spanish dub of the second season, Juan Alfonso Carralero decided not to reprise his role as Taurus Harbingir, so Carralero was replaced by Creator/AlfonsoObregonInclan.
* PlayingAgainstType: Creator/HikaruMidorikawa (Kouga), as he tends to play cool, collected characters.
* RecycledScript: The whole series is ''heavily'' based on the Sanctuary arc of the original series, to the point of being called just a rehash. Bronze Saint tournament, journey overlapping with battle against the Silver Saints, and now even ''another'' "climb the Twelve Temples" arc. Many new characters are [[{{Expy}} very similar]] to old ones, too.
** [[AvertedTrope Averted]] with the second season.
* RealLifeRelative:
** Gerardo Alonso and Jahel Morga, the Mexican voice actors for Wolf Naruto and Aquila Yuna, are husband-and-wife.
** Also from the Mexican dub, real-life brothers Luis Fernando and Alejandro Orozco play Max Brilliant Methone and Soul Killer Cyllene, respectively.
* RelationshipVoiceActor: They don't just bring in ''Anime/HeartcatchPrettyCure'''s Character Designer, but also two [[Creator/HikaruMidorikawa cast]] [[Creator/AyaHisakawa members]] from them... though [[BigBad Dune]] is now the IdiotHero while [[DefrostingIceQueen Yuri/Cure Moonlight]] is the DarkActionGirl.
** To be frank, a lot of ''Anime/PrettyCure'' voice actors are in this one. For one thing, Yuna and Ryuhou are, respectively, [[Anime/SmilePrettyCure Akane/Cure Sunny]]'s mother and ImpliedLoveInterest, with the former also being [[Anime/SuitePrettyCure Hibiki/Cure Melody]]'s mother; Aria was previously [[Anime/PrettyCureAllStars Ayumi/Cure Echo]]; Raki is [[Anime/YesPrettyCure5 Karen/Cure Aqua]]; Gemini Paradox is none other than [[Anime/FutariWaPrettyCure Honoka/Cure White]]; Cancer Schiller is [[Anime/FreshPrettyCure Tarte]]; and Pisces Amour (who also happens to be the aforementioned DarkActionGirl's uncle) is [[Anime/HeartcatchPrettyCure Cologne]].
** Also [[Creator/TetsuyaKakihara Ryuhou]] vs [[Creator/{{Yukana}} Paradox]] gets HilariousInHindsight when you realize it's basically [[VideoGame/BlazBlue Jin Kisaragi vs Saya]]. Switching place on who's being the 'bullied' party.
* RoleReprisal: Creator/MamiKoyama reprises her role as Shaina, and Creator/YukitoshiHori reprises his role as Tatsumi. Creator/ToruFuruya returns as Seiya after 6 years.
** Many of the Mexican Spanish dubbers from the original series got to keep their roles as well. Some of the few exceptions include Jesse Conde voicing Dohko after the passing of his original VA Eduardo Borja.
* TalkingToHimself: [[spoiler: Creator/{{Yukana}} voices the twin sisters Paradox and Integra. She spends a good portion of episodes 75 and 84 switching between the two characters.]]
** The same trick was used in the Mexican Spanish dub, [[spoiler: with Adriana Casas switching between one twin and the other.]]
* WhatCouldHaveBeen:
** In the Mexican Spanish dub, Creator/YamilAtala originally [[TheOtherDarrin replaced]] Creator/JesusBarrero as Pegasus Seiya due to the latter's disagreement with the budget and Atala even recorded some of his lines as Seiya for the first episode. However, this ended up being a case of TheOtherMarty when Barrero amicably settled his budget dispute and reprised his role, re-dubbing Atala's dialogue from the first episodes. As a bonus, Atala stayed in the cast and went on to voice both Libra Genbu and Marine Ushio.
** Also from the Mexican Spanish dub: Mireya Mendoza (Relena from ''Anime/GundamWing'', Shizune from ''Manga/{{Naruto}}'', Penny from ''Series/TheBigBangTheory'', etc) was at first contacted to play Saori/Athena, but she told the cast people to contact Saori's original VA Creator/MariaFernandaMorales and offer ''her'' the role, which she (Mendoza) would only take if Morales was unavaliable. They did, and Morales accepted to voice Saori again.
