- Acting for Two:
- Megu Sakuragawa voices Lumen, Joule, and Mytyl.
- Maxwell Powers, a Japan-based English voice actor, doubles as the Inti Creates trailer narrator and Asimov's voice in the OVA.
- Bad Export for You: The original release of Azure Striker Gunvolt axed the vast majority of the script (including in-stage dialogue and most Joule Chats), turned the remaining story into an Excuse Plot, and added some "original" flair like fake not-fake "swearing." The displeasure from fans was immense, leading to a fully complete, overhauled translation job for the Steam release that was later ported to the 3DS as a patch and the Striker Pack release.
- Creator's Favorite: Inti loves Gunvolt (the character). They can and are perfectly willing to remind its target audience that Gunvolt exists, and have crammed a Gunvolt reference or Gunvolt himself into nearly every single game they've produced since 2014.
- Crossdressing Voices: Chiaki Omigawa voices Xiao.
- The Danza: Maria Naganawa voices Maria in Luminous Avenger iX.
- Market-Based Title:
- Azure Striker Gunvolt 2 was originally known as "Armed Blue Gunvolt Sou". The word "sou" in Japanese refers to a claw or talon, which Copen uses in some analogies.
- THE OUT OF GUNVOLT: iX of the White Steel was changed into the much more palatable Gunvolt Chronicles: Luminous Avenger iX.
- Milestone Celebration: Azure Striker Gunvolt 2 is Inti Creates' 20th anniversary game.
- Name's the Same:
- Gun Volt is also the name of a mook in Mega Man X.
- The term "Flashfield" is used in both the English and Japanese versions of the game, but in different contexts. In the English version, Flashfield is the name for Gunvolt's self-generated electrical force field. In the Japanese version, however, Flashfield is the name of Copen's protective barrier in 2.
- No Dub for You: All of the games do not have English dubs. The OVA averts this, although Japan-based English voice actors were brought in to do the dub.
- No Export for You:
- The official soundtrack and accompanying vocal soundtrack were this. This went the other way when the Steam version hit, where both the OST and the vocal soundtrack were digitally published via Steam in all available countries; FanGamer also carries these soundtracks physically. However, the drama CDs still have yet to see an English release.
- Although the OVA is available worldwide on 3DS and in dual audio with subtitles, the DVD release however was only bundled in the Japanese Limited Edition release of the Striker Pack for the Nintendo Switch along with another drama CD that centers around Copen, Joule, and Quinn.
- The Other Darrin: In iX, both Copen and Lola have new voice actors, Yuuma Uchida and Mayu Mineda respectively. According to the developers, this is because this game is, "The mark of a new series." (And also because Yurika Endo retired from the entertainment industry).
- Pre-Order Bonus:
- As with many Japanese games, pre-ordering the Striker Pack from a specific retailer in Japan will earn you a particular, retailer-exclusive bonus. In addition, if you pre-order from Amazon, GEO, or Bic Camera/Sofmap/Kojima, you will acquire two Audiolockets and Program Codesnote for Gunvolt and Copen respectively in 2 that allow you to play songs from the first game when you hit 1000 Kudos.
- Pre-ordering iX awards a DLC Lola outfit for Kohaku.
- Schedule Slip: The OVA was originally planned for release on December 2016, but was delayed to Winter 2017, and eventually released on February 9, 2017.
- Series Hiatus: Fleeting Memories has been on indefinite hiatus since 2016, with the story for the first season ending on a Cliffhanger.
- Talking to Himself: Lumen and Joule, both voiced by Megu Sakuragawa. She also voices Mytyl, who inherits the power of both muses.
- What Could Have Been:
- At one point, it was considered that Gunvolt's ponytail and midriff should be removed for the localization to appeal to a teen demographic. While the midriff was censored, the censored midriff was cut from future games, and Gunvolt's ponytail was kept in per request by Keiji Inafune.
- In the original draft for 1, the bad end was the only end and had far greater consequences. Nova's death would cause the defense barrier protecting Japan to go down, enabling an invasion by foreign powers who spearhead the attack with missile strikes. Gunvolt would attempt to stop them, at which point Asimov betrays him and that's that. The ending would be Asimov grinning as the missiles struck. This missile attack would later serve as the basis for The Seven's names, which are all based on various missile systems.
- The "man in the butterfly mask" design that was revealed long before the second game's release is ultimately unused. It would eventually see use in the spinoff game Mighty Gunvolt Burst, as the design for the GM in Beck's story.
- The original concept for 2 involved Copen going up against Sumeragi, which was helmed by a masked, evil Gunvolt. Gunvolt would be a boss fight in which he would use 1000 Glaives to transform, and beating him would unlock him as a playable character. While the original concept was scrapped, the idea of having a masked Gunvolt would be fused with the aforementioned scrapped design and later used in Mighty Gunvolt Burst, and elements of a continued Sumeragi with an Identical Stranger in color and powers to Gunvolt (complete with mask/helmet to hide her identity) as a high-ranking member were brought in for Luminous Avenger iX.
- In the aforementioned earlier concept of 2, Xiao was intended to be a playable character alongside Copen.
- Lola was originally going to change her human look based on the EX Weapon equipped. This turned out to be too much work to implement, and was scrapped, with only her drone form turning different for each EX Weapon. The idea was then revived for Luminous Avenger iX.
- The Wiki Rule: Has one here.
