* NamesTheSame:
** Mr. Sakurai, the English teacher and Mrs. Sakurai, the head of school, are not related. In the anime, Mr. Sakurai is renamed Sakurada to prevent confusion.
** Kunio Murai is not to be confused with the Japanese actor of the same name.
** Speaking of Murai, his crush shares the same name with a [[Creator/AkaneFujita Japanese seiyu]].

* LongRunners: ''GTO'' is an interesting case. The manga itself only lasted 5 years (1997-2002) with 207 chapters, but it continued the story begun with ''Manga/GTOTheEarlyYears'' (1990-96), which had 267 chapters (plus the 10-chapter OriginsEpisode ''Manga/BadCompany''). Tooru Fujisawa then took a break for a few years, before returning to Onizuka's story with ''GTO: 14 Days in Shonan'' (2009-11, 77 chapters) and ''GTO: Paradise Lost'' (2014-present, currently at 144 chapters). This is excluding the non-Onizuka-centric stories ''GT-R: Great Transporter Ryuji'' (2012), ''Ino-Head Gargoyle'' (2012-2014), and ''Shonan Seven'' (2014-2019), which take place in the same universe. Therefore, the "GTO-verse" has run for 24 non-consecutive years over 8 different series (5 of them about Onizuka himself, over 21 years).

* AdaptationOverdosed: ''GTO'' has a 43-episode anime adaptation, a live-action film, and no fewer than 4 live-action TV series. And then there's the spinoff ''GTO: 14 Days in Shonan'' and the sequel ''GTO: Paradise Lost''. Its predecessor ''Manga/ShonanJunaiGumi'' also has several live-action adaptations and an {{OVA}} series.

* RomanceOnTheSet: The live-action actors of Onizuka and Fuyutsuki ended up together in RealLife.

* UnintentionalPeriodPiece: The fact that ''Ape Escape'' is used as ProductPlacement in the anime sets the series during the 90s. Somewhat delves into PacManFever territory with ''VideoGame/WildArms 3'', a [=PS2=] game, being played on Onizuka's [=PS1=], though.

** Within Shonan Junai-gumi itself, Creator/TakumiYamazaki voiced Tsuyoshi Tsukai for the first two episodes, but was replaced for some reason by Creator/ToshiyukiMorikawa in the fourth. Morikawa also voiced the villain of the fifth and final episode, Kunito Nakajo.
** Also, in the GTO anime, minor supporting teacher Koji Sannomaru was voiced by Creator/TsutomuTsuji for his first couple of appearances before being replaced for the remainder of the show by Creator/HirohikoKakegawa.

** Kunio was first voiced by Creator/BrycePapenbrook in episode 4 (alongside [[Creator/BobPapenbrook his father]] who voiced Uchiyamada and some extras) before being replaced by Creator/TonyOliver for the rest of the run. Bryce was attending college at the time and couldn't devote any more time to the series.

** As for Anko's lackeys, Mayuko was voiced by Debbie Rothstein for volume 2 but way down the line in volumes 9 and 10, because of the above mentioned with Saeko, was replaced by Kate Higgins. Naoko, on the other hand, had four different actresses. Cindy Robinson voiced her in volume 2, but since she was now filling in as Anko for that volume, she didn't reprise the role, leaving it to be filled by Christine Ruprecht. Since Cindy was already voicing Saeko for the Okinawa episodes, Naoko was recast a third time with an uncredited Creator/LaraJillMiller on volume 9. Miller did not return for the final volume so Naoko had to be recast yet again, this time with Creator/KarenStrassman.

** Speaking of the fourth episode, another oddity was that Anko and Miyabi's actresses, Creator/DorothyEliasFahn and Creator/WendeeLee respectfully, originally had their roles reversed with Wendee even voicing Anko in the preview for the next episode. After which, Dorothy stayed with Anko for the remainder of the show except in volume 3 when she wasn't available, so Creator/CindyRobinson voiced the character for episode 14. Wendee would continue on as Miyabi from episode 7 to the series' end.

Naoko, on the other hand, had four different actresses. Cindy Robinson voiced her in volume 2, but despite her still voicing characters in volume 3, didn't reprise the role, leaving it to be filled by Christine Ruprecht. Since Cindy was already voicing Saeko for the Okinawa episodes, Naoko was recast a third time with an uncredited Creator/LaraJillMiller on volume 9. For unknown reasons, Miller did not return for the final volume, so Naoko had to be recast yet again, this time with Creator/KarenStrassman.

* StarMakingRole: Onizuka was Creator/WataruTakagi's breakout role as the main character.

** That was nothing compared to their [[GirlPosse Girl Posses]], who never had consistent actresses in the dub. Poor Saeko had a grand total of '''FIVE''' different actresses voicing her across all her appearances! First Creator/ChristineRuprecht voiced her in episode 7, next Creator/PhileceSampler in episode 9, then Creator/DebbieRothstein was settled on as the de facto voice (with Wendee Lee filling in for volume 4). However, Debbie did not return for volume 7 and onwards, so Cindy Robinson finished up for Saeko's remaining speaking parts.
** Chikako faired far better in comparison; she was mainly voiced by Sampler with the sole exception of episode 16, where Creator/KateHiggins filled in.

** The Holy Forest staff also fell victim to this early on, with Creator/BradRowen and Wendee Lee voicing Sakurada and Kochatani, the latter was especially noticeable since the male teacher was voiced by a woman. Steve Blum, already voicing Onizuka and Fujiyoshi, would take over as Kochatani for the rest of his speaking appearances while Tony Oliver would voice Sakurada in episode 6 only before handing the role to Dave Wittenberg for the rest of the run.
** Saejima was voiced by Creator/RichardEpcar (already Fukuroda) for his first two appearances but was replaced for some reason by Creator/SkipStellrecht for his remaining three outings.

** On a minor note, Tomoko's father was voiced by Wittenberg in episode 9 but got replaced by Tony Oliver in the penultimate episode.
