In Star Fox 64's ancillary material, Planet Aquas is said to be an entirely water planet with its surface 100% covered by oceans. Star Fox Command however, would contradict this by showing there to be islands on Aquas in the Slippy's Resolve ending; Command's official Japanese guidebook even claims that Aquas' surface is now only 80% comprised of oceans.

In a Q&A with Takaya Imamura in 2023 on this subject, he theorized that perhaps, somewhere in-between the events of Star Fox 64 and Star Fox Command, the islands were created by underwater volcanic belts within Aquas' oceans, likening it to the emergence of Nishinoshima, a volcanic island in the Ogasawara Archipelago.

When Peppy Hare appears as a playable pilot in the "Goodbye Fox" story route, he dons his classic outfit from the original Star Fox and Star Fox 64, his green scarf in particular hailing from the former (in the latter game, he instead wears a red scarf).

In a June 1997 Nintendo Dream interview with Shigeru Miyamoto regarding Star Fox 64, when asked if he would produce a sequel, Miyamoto responded with:


Funny enough, both of these ideas would come to fruition with future titles such as Star Fox: Assault, which hugely emphasized its multiplayer battle mode, and Star Fox Command, which revisited many of the real-time strategy elements that were previously experimented with in the then-unreleased Star Fox 2.

The English prologue for Star Fox Command, when describing Falco's whereabouts after he left the Star Fox team yet again, says:


This actually omits one small detail from the Japanese script: that Falco went back to hanging out with Katt Monroe and presumably the rest of his old gang, FREE AS A BIRD. Here is the original Japanese text, for comparison:


Which translates to:


This adds up, as one can even see Katt's ship in the background of Falco's profile within the prologue.

The character of Octoman is portrayed as much more angry and agressive in the English localization of Star Fox Command than he is in the original Japanese script. Take for example, this bit from the Slippy's Resolve story route:


Re-translating the Japanese text, however, reveals:


Also in the English version of this game, Octoman has a rather baffling line later on in this same story route, where, when facing against Slippy and his fiance Amanda, he tells his subordinate Zako (Sharman in the Japanese version) this:


It goes without saying that this does not appear to make any sense because Slippy and Amanda are frogs, not humans.

However, re-translating the Japanese text reveals:

The character of Panther Caroso (or Caruso as he's called in Command) infamously speaks in the third-person throughout Star Fox Command, despite not doing so in his debut game, Star Fox: Assault.

It turns out that this is yet another quirk of Command's English localization, as Panther speaks normally in first-person in the Japanese script just as he did in Assault.

Here are three of Panther's lines in-game during the Star Wolf bossfight:


However, re-translating the original Japanese text will reveal:


Another example is this conversation here:


Here's this same conversation re-translated from the Japanese script.

Star Fox: Assault introduces a new team member for Star Wolf, Panther Caroso, who fills in the space left behind by the departures of Andrew Oikonny and Pigma Dengar. He reappears in its sequel, Star Fox Command, but with a slightly different name: Panther Caruso.

Both of these are actually mistranslations of his intended surname in Japan, which is カルロッソ (Karurosso), or Caluroso. "Caluroso" is the Spanish word for warm, hot, energetic, enthusiastic, etc., which is in line with his womanizer, Latin, and Giacomo Casanova-esque personality and archetype.

Dash Bowman is notably the only playable pilot in all of Star Fox Command outside of the Star Fox (Fox, Falco, Peppy, Slippy, Krystal, and even James) and Star Wolf (Wolf, Leon and Panther) teams to be select-able against the Emperor Anglar, essentially the game's true final boss, on Venom.

The only last bosses the other playable pilots can go against are the Splitter in the Lucy and Krystal storyline (which is fought by Katt, Lucy, Amanda as well as Krystal), and Pigma in the Pigma's Revenge route (which is fought by Katt, as well as Falco).

Bill Grey only appears in two missions on Katina and thus is the only pilot to not be involved in the last battle of any of Command's story routes, and also the only pilot (besides James) to not be featured in any of the nine endings.

One of the most common criticisms regarding Star Fox Command's narrative from fans is the way it portrays Krystal as seemingly far more cold, harsh and bitter than she was in the previous Star Fox titles she appeared in. While some of this angst is still present in the Japanese script, there is comparatively much less of it and is written in a less exaggerated tone than in the Western localization.

For example, take this conversation:


Here's this same conversation, but re-translated from the original Japanese text:


Notice how more aggressive Krystal comes across in the English script, something Falco takes note of, in comparison to the retranslated text where's she portrayed as more considerate.

Another example is during one of the Katina missions:


But re-translating the Japanese script, it reads like this:


Obviously, Krystal is still portrayed as not being on good terms with Fox, but one can see the extra venom Nintendo of America included in their localization, by having her flat out call Fox a loser.

Another major example is this conversation at the end of the Fox and Krystal storyline:


Now, here's the Japanese version of this retranslated:


Krystal appears to be much more remorseful about her attitude and actions towards Fox (i.e joining up with Star Wolf and forcing him to beg for forgiveness in order to get her to rejoin the team) than she does in the English translation where she continues to be rather bitter and sarcastic towards him, to the point where she doesn't even thank Fox unlike with Falco and Slippy, which contradicts the original Japanese script.

During Star Fox: Assault's Fortuna mission, Andrew Oikonny, who is now leading a rebellion against Corneria using the remnants of Andross' army, pilots a flagship that transforms into a mode based on his deceased uncle (Falco even dismisses it as a "Andross wanna-be") complete with a floating head with disembodied hands. The official Japanese Star Fox: Assault guidebook reveals its name to be デスバブーン (Desubabūn), or Death Baboon.

Despite being seemingly destroyed by an Aparoid, Oikonny would reappear in Star Fox Command, working for the Anglar Army (who are revealed to be creations of his uncle), this time in another vessel shaped and named after an animal that's name also starts with "Death", the Death Crab.

Unusued icons found within Star Fox Command curiously show ROB 64 with the original Great Fox as it appeared in previous installments such as Star Fox 64 and Star Fox: Assault. This is odd, because the Great Fox was already shown to be completely destroyed in the climax for the previous game, Star Fox: Assault, which is why it was replaced with a small space carrier in the final version of Command.

This indicates that this was either merely a placeholder, or at some point, the development team had considered bringing the original Great Fox model back as it was prior to Assault's ending.

One of the Anglar Army's commanders in Star Fox Command is a hammerhead shark looking character named "Zako", who's also a subordinate of Octoman.

His Japanese name, however, is シャーマン (Shāman), which can either translate to just "Shaman" or even "Sherman". Looking at the English text provided in the official Japanese Star Fox Command guidebook, it seems the intended name is "Sharman". It's fairly obvious that his name is combination of "Shark" and "Man", and that it's also meant to complement and mirror Octoman's name.

The Aparoids are unique in Star Fox's rogue gallery in that they're the only main enemy forces, at least within the official game canon (which includes "Farewell Beloved Falco", the manga interlude between Star Fox 64 and Star Fox Adventures) to have absolutely no connections or ties to Andross whatsoever:

• In Farewell Beloved Falco, Captain Shears, despite being affiliated with the Cornerian army, was revealed to be a turncoat seeking to revive Andross through cloning.

• In Star Fox Adventures, General Scales and the SharpClaw were revealed to be the unwilling pawns of Andross' ghost, who manipulated them as well as Fox to revive himself using the power of the Krazoa.

• In Star Fox Command, the Emperor Anglar and his Anglar Army are revealed to be bioweapons created by Andross in secret within Venom's acidic oceans.

In particular, the Aparoid Queen is the only final boss in all of the Star Fox series to either not just be Andross again (Star Fox, Star Fox 2, Star Fox 64/Star Fox 64 3D, Star Fox Adventures, Star Fox Zero), nor a creation of his (Star Fox Command).

For Star Fox 64 3D, Bill Grey's fighter craft in the Katina mission was redesigned to be closer in design to its appearance in Star Fox Command. It was probably also done to distinguish it from the other Cornerian Fighters present in the mission, which Bill's fighter looked identical to back in the original Star Fox 64.

Krystal has the unique distinction of being the only playable character in Star Fox Command to pilot two different spacecrafts and also sport two different attires depending on the route taken.

In some missions, primarily when she rejoins Star Fox, she wears a pink jumpsuit and pilots the CloudRunner. In other missions, primarily when she's hanging with Star Wolf, she wears a traditional Cornerian Defense Force attire with a flight jacket, scarf and helmet, and she pilots the Cornerian Fighter that Bill Grey also uses.

As it currently stands, barring Star Fox 64 3D, Macbeth is the only planet from Star Fox SNES and Star Fox 64 to not have reappeared in future games.

•Corneria, Fichina, Katina, and Fortuna would reappear in Star Fox Assault. Titania and Zoness would appear in Star Fox Assault's multiplayer mode as well.

•Corneria, Fichina, Katina, Solar, Aquas, Titania and Venom would reappear once again in Star Fox Command.

•Corneria, Fortuna, Fichina, Zoness, Titania and Venom would also reappear in Star Fox Zero.

According to the official Japanese Star Fox 64 guidebook, the main driving point for Wolf O'Donnell's rivalry with Fox McCloud is the fact that Wolf was previously rivals with his father, James. This is alluded to in-game with various voice clips from Wolf across Star Fox 64, Star Fox Assault and Star Fox Zero, and it's also reiterated in the timeline of events provided in Star Fox Command's official Japanese guidebook.

The English manual and prologue for Star Fox Adventures implies a bigger backstory for Krystal, in that she's the sole remaining survivor of her doomed home planet, "Cerinia", and that she's been roaming the galaxy in search of answers for the truth of her family's death, until she receives a distress call from Dinosaur Planet. With how the manual states that Krystal "may finally be drawing closer to the truth" behind her parents' and planet's destruction, it seems Rare was loosely implying that Andross, who turns out to be the real villain of Star Fox Adventures and thus the culprit behind Dinosaur Planet's woes, was responsible for Cerinia's destruction. Krystal even says "It's you!" right before Andross imprisons her in the crystal at the top of Krazoa Palace.

However, it would seem the Japanese localization for Star Fox Adventures would completely eschew this backstory, removing all mention of Cerinia and as well as Krystal's dead parents. The Japanese prologue was even heavily simplified to this:


The Japanese website even states that "it is not known what her purpose is", which flies directly in the face of Rare's original story for her, that explicitly states that she was searching for the truth of Cerinia's destruction. To add more insult to injury, there isn't even any Japanese subtitle presented when Krystal gets knocked into the crystal by Andross in Krazoa Palace.

Curiously, the Japanese localization of Star Fox Adventures also heavily emphasizes Krystal having telepathic abilities, much more so than in the English version. This is noteworthy because neither Star Fox Assault or Star Fox Command, the next two story follows up to Star Fox Adventures that were developed and written in Japan, made any sort of mention of Cerinia. Star Fox Assault however would hugely emphasize her telepathic abilities, and its manual even describe Krystal the same way the Japanese version of Star Fox Adventures does, just as "a mysterious telepathic woman". This also applies to her trophies in Super Smash Bros. Brawl and Super Smash Bros. for Nintendo 3DS and Wii U that once again make no reference to Cerinia. It's very clear that the developers and writers behind Assault, Command and Smash Bros. in Japan were using the Japanese version of Star Fox Adventures as a reference, as opposed to the English version.

All in all, it would seem Nintendo of Japan had their own differing vision of what Krystal's character was from Rare, that being mostly just as a telepathic woman with a mysterious background, as opposed to Rare's original backstory of her being the lone survivor of her kind.

According to Dylan Cuthbert in an Reddit AMA back in 2018, the in-game sprites used for the characters in Star Fox Command were all originally created as 3D models that were then rendered to create the sprites. Cuthbert has implied that these 3D models still exist somewhere in Q-Games' archives.

All in all, it would seem that the entire Star Fox chronology, at least as it was presented from Star Fox 64 to Star Fox Command, spans roughly 20 years.

Star Fox 64's whole backstory take place across 10 years, beginning with Andross' banishment to Venom and then James' death/betrayal on Venom five years later, and the events of Star Fox 64 taking place another five years later after that. The Japan-only "Farewell Beloved Falco" Manga, the canonical manga follow up to Star Fox 64 and prelude to Star Fox Adventures, would take place four years later, and SFA would take place another four years later after that. Star Fox Assault takes place one year after the events of SFA, and Star Fox Command was said to take place a vague 2-3 years after the events of Assault. This would amount to overall roughly 21-22 years.
