- Awesome Music: "Rock Cafè" from Part I and "Himitsu Kudasai" (Please Tell Me the Secret), from the end of Part II.
- Broken Base: The Mega Zone 23 fanbase can't seem to decide on much of anything.
- Which installment of the series is the best? Is Part II an interesting, different, unique continuation of the series, or is it just a mindless gorefest?
- Which English dub of the series is best? The Streamline Pictures dub of Part I? The Manga UK dub of Part III? The ADV Films dub of the entire series?
- Speaking of which, is the ADV dub a well-done adaptation of the original, or does it suffer from Totally Radical rewrites and overzealous acting due to a bad direction job?
- Harsher in Hindsight
- The monitoration of E-mails and people in cyberspace are identical to NSAleaks in Part III.
- Eve never has a relationship with Shogo or Eiji. Idol singers have gone on record as being forbidden to date to keep their image pure.
- Hilarious in Hindsight:
- EVE is initally portrayed as an digital Idol whose voice and appearance is sampled from, in universe, a young girl who worked on the Megazone project, identically to how a Vocaloid is created.
- The series was envisioned as a 12-episode series, but the sponsors pulled their support halfway through, forcing it to be compiled into four slightly disjointed movies. However, the series length is roughly 260 minutes long, including credits. One episode in anime is 20 minutes long without credits. Work it out.note
- Ho Yay: Part II. An article in an old anime-focused e-magazine had a first-time viewer of the Harmony Gold dub tell the writer that "Johnny Winters" was gay as soon as it was over. Exhibit A: the scene where Shogo and Lightning light each other's cigarettes while looking into each other's eyes.
- Macekre: The Harmony Gold release.
- Marth Debuted in "Smash Bros.":
- In the United States, Megazone 23 only appeared as a poorly received part of Robotech.
- In the United Kingdom, due to the poor reception of the Harmony Gold dub, Their exposure to Megazone 23 was solely Part III, merged into one two-hour long film.
- It took until ADV Films releasing a consistent dub of all four parts before ANYONE in the English-speaking countries got the full story.
- Narm: Aside from the obvious/already-stated, there's Yui's voice in the new dub. Some overlap with Most Annoying Sound.Yui: WAAAAAAAAAAAAAAAAAAAAAAAT!?!?!!?!!?!?!?!?
- Cyndi in Part 2 is worse - and even more annoying. Of course, being voiced by Tiffany Grant, that's to be expected.
- Retroactive Recognition: In the Harmony Gold release, Wendee Lee voiced Stacy Embry (Mai). Wendee would go on to voice characters like Faye Valentine, Twilight Suzuka, Yoruichi Shihoin, Haruhi Suzumiya and Konata Izumi, among others.
- Meanwhile, Robert V. Barron - who voiced Professor Embry - later became Abraham Lincoln.
- Superlative Dubbing: Depending on who you ask (see Broken Base at the top of this page), any of the uncut series dubs could qualify for this (the dubs done by Streamline Pictures, ADV Films and Manga UK, to be precise).
- Suspiciously Similar Song: Does anybody else think that "Himitsu Kudasai" sounds like "It's a Sin" by the Pet Shop Boys?
YMMV / Megazone 23
