According to Takaya Imamura in a 2011 Nintendo Dream magazine interview, Fox McCloud's mother is actually still alive and well on their home planet of Papetoon. This is in contrast with the 1994 Nintendo Power comic series, where it was revealed that Fox's mother (named "Vixy Reinard") was accidentally killed by a car bomb planted by Andross that was intended for her husband ("James" as he would referred to in the games starting with Star Fox 64).

According to Imamura, Fox's mother disapproved of her son following in her husband's footsteps and potentially getting himself killed the same way, and thus they have become estranged from each other, though they haven't exactly broken off from each other completely. Imamura even hints that she's secretly supporting her son's actions from behind the scenes.

Concept art for Star Fox 64 3D suggests that the development team at some point considered creating an all new Arwing model design, one that appears to be a mixture of the classic Star Fox 64 design and the sleeker, sharper Star Fox: Assault design, similar to how the Landmaster was redesigned to resemble its 64/Assault amalgamated design from Super Smash Bros. Brawl.

One of Falco Lombardi's most famous lines in Star Fox 64 is "Hey, Einstein! I'm on your side!"

This line is somewhat controversial because it implies that there exists some version of scientist Albert Einstein within the Star Fox universe. It is worth pointing out that this was added in for the Western localization of Star Fox 64, as in the Japanese version of the game, Falco simply just says:


Ultimately, the Western version of Star Fox 64 3D would have this line be changed to: "Hey, genius! I'm on your side!"

As admitted by Mitsuhiro Takano (the original script writer for Star Fox 64) in an issue of Iwata Asks regarding Star Fox 64 3D, the development team had initially planned on including more aquatic stages based around the Blue Marine in the original game, but these were removed because they felt they dragged down the pace too much. In the Japanese version of the Aquas stage in Star Fox 64, Falco says:


English SF64's equivalent to this is "This thing will never hold together."

Apparently, this was the result of Takano feeling bad about there only being one underwater stage in all of SF64's single-player mode.

Going by files pertaining to Star Fox 64 found within the Nintendo Gigaleak, it seems one of these cut Blue Marine stages was known as カトレア (Katorea), which properly translates into Cattleya. Cattleya is a genus of orchids, which adds more credence that this was planned to be a beautiful water planet. The planet's initials (CL) show up in many other other source files, which gives clue to what it would've been like; for example, fox_edisplay references CL_SHIP0, CL_SHIP1, and fish00, whereas fox_boss.h refers to CL's boss as 鯖/saba, or "mackerel.” fox_jyuza.o meanwhile refers to a "saba snake", which heavily implies that the stage's boss would have been a giant fish creature or an eel of some kind.

Most of the other files label CL as "Colony", which implies that Cattleya would have been home to underwater cities. In beta versions of the map, CL is positioned between where Area 6 and Bolse would be, and presumably would have led into the cut planned Venom Normal route where Fox would have battled Andross on-foot with a bazooka.

When asked about the canonicity of Star Fox Command in relation to its predecessors (those in particular being Star Fox 64, Star Fox Adventures and Star Fox: Assault) in a Reddit AMA, Dylan Cuthbert had this to say:


In turn, many within the Star Fox fandom figured that he was implying that the game itself was not canon to the previous installments. However, years later, Cuthbert would clarify on what he really meant by Command being an "alternate timeline kind of game":


In reality, it seems what Cuthbert really meant was that each playthrough and story path is meant to represent an alternate timeline, not that Command itself was in a separate timeline from 64, Adventures, and Assault. Nintendo Dream's guidebook for Star Fox 64 3D from 2011 would actually include an entire chronological timeline of the series up to that point, beginning with Star Fox 64 and ending with Star Fox Command.

Essentially, all of the game's branching story paths are canon and non-canon at the same time, as there's said to be no true ending as it's up to the players to decide how Command, and perhaps the entire series' chronology as it truly began in 1997, ends. A 2011 Nintendo Dream magazine interview with Dylan Cuthbert, as well as Takaya Imamura, would reiterate this sentiment.

A 3D polygonal model based on the Arwing from the first Star Fox was discovered within Star Fox 64 3D's files. It is not known if it had anything to do with Q-Games' pitch to Nintendo of a Star Fox SNES remake that was ultimately rejected, though it's worth pointing out that that occurred after Star Fox 64 3D's release.

One of the more enigmatic characters in Star Fox 64 is the tanuki or raccoon dog that only appears in its training mode. On the official Japanese Star Fox 64 website, Slippy reveals that his name is ヤル・デ・ポン (Yaru De Pon), and that he is the president of Space Dynamics, the manufacturers of the Arwing and other vehicles the Star Fox team utilizes in their missions.

His surname seems to reference the du Pont family (ポン spells both "Pon" and "Pont"), a wealthy American family who made their fortune selling gunpowder, and later chemicals and motor vehicles. A popular rumor is that Henry A. du Pont secretly sold gunpowder to the Confederacy during the Civil War; fittingly enough, Slippy implies that Yaru de Pon is involved in "shady weapon deals", suggesting that he might be supplying Andross' forces as well.

Yaru de Pon is also notably the only character in the original Star Fox 64 to not have any voice acting. This was addressed in its 3DS remake, Star Fox 64 3D, where he is now properly voiced by Jay Ward (who also voices Wolf O'Donnell in Super Smash Bros. Brawl and Super Smash Bros. Ultimate, as well as the Nintendo Switch version of Starlink: Battle for Atlas) in the English version, and Kunpei Sakamoto in the Japanese version.

According to the brochures distributed with Star Fox 64 3D in Japanese retail stores in 2011, it was Pigma Dengar who designed the Star Fox logo during his tenure with the original team, before he betrayed them.

The North American release of the game was originally announced to be September 11, 2011, but it was pushed forward by 2 days, likely so that it wouldn't coincide with the 10-year anniversary of the terrorist attacks carried out against the United States on that same day.

Star Fox 64 3D features an entirely new battle multiplayer mode unique from the battle mode found in the original Star Fox 64, where up to 4 players can play a local multiplayer match via Download Play (or alternatively, battle against CPU opponents). However, the game did not support online play.

Nintendo's Yusuke Amano explained in an interview in 2011 that the game's battle mode did not support online play due to both cost and time constraints, with the developers deciding to prioritize the 3D visuals, as the point of the project was to use Star Fox to provide users with a game that showed the capabilities of the Nintendo 3DS as quickly as possible:

The go-to term for the initial conflict of the Star Fox series, as told in three different installments (Star Fox on SNES, Star Fox 64, and Star Fox Zero), is the "Lylat Wars". This name originates from the original PAL release of Star Fox 64, where it was renamed to Lylat Wars due to trademark issues (similarly to why the first Star Fox was renamed to "Starwing" there as well). In comparison, its 3DS remake, Star Fox 64 3D, would retain the Star Fox 64 moniker in all regions. Nintendo would later actually canonize the "Lylat Wars" moniker as the official name of the conflict against Andross' forces in the opening prologue to Star Fox Zero.

Many Star Fox 64 players have referred to the Venom army general piloting the mecha boss encountered in the Easy Route Corneria path as "Granga", presumably because of the Star Fox 64 Nintendo Power Official Strategy Guide referring to him as such.

In reality, or at least going by the official Japanese Star Fox 64 guidebook and also Star Fox 64 3D, the name "Granga" actually refers to the aforementioned mecha itself. Like most of Andross' lieutenants (with the exception of Caiman), the pilot himself seemingly never had a proper name.

In a 2011 Nintendo Dream interview with the development staff of Star Fox 64 3D, Yusuke Amano joked that a future Star Fox game could be a dating simulator:

In Star Fox 64 3D's ending, the conference hall where the Star Fox team meets General Pepper after Andross' defeat was changed from its original appearance into a hangar, with fewer, more spread out Dog soldiers.

More notable, however, is how the generic planet Corneria image and lettering at the back of the room has been replaced by the Cornerian Army logo that first appeared in Star Fox: Assault.

Across two interviews with two different Nintendo Dream issues in 2011, Takaya Imamura expressed quite a bit of interest in creating a prequel to Star Fox 64 starring James McCloud and the original Star Fox team, mentioning the idea three times, unprovoked. He also even suggested a future game could be a soft reboot set several years later with a new lead instead of Fox.

From the Star Fox 64 3D Developer interview in the September 2011 issue of Nintendo Dream:


Shortly aftwards, after being asked about the future of the Star Fox series:


In a later interview, Imamura says:


Unfortunately, nothing has ever come of this. All the Star Fox series has seen since then is the release of Star Fox Zero (a reimagining of Star Fox 64), Star Fox Guard (a tower defense game set around the same time), and an official release of the 20-year old game Star Fox 2. Takaya Imamura would retire from Nintendo in early 2021.

The Landmaster's appearance as Fox, Falco and Wolf's Final Smashes in Super Smash Bros. Brawl and Super Smash Bros. for Nintendo 3DS and Wii U is a composite of its appearances from Star Fox 64 and Star Fox Assault, maintaining the sharp and futuristic appearance it had in the latter, but still retaining traditional tank treads as seen in the former.

This particular design would eventually be implemented into the Star Fox series proper, beginning with the Landmaster's appearance in Star Fox 64 3D, and would be used again in Star Fox Zero.

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.

The official Japanese Star Fox 64 guidebook reveals that the Great Fox's creation by Space Dynamics was commissioned by Fox's father, James McCloud, who was involved in its design from the planning stage. Its enormous cost incurred in its construction resulted in James taking out an 80-year mortgage to purchase it, a debt that Fox is still trying to repay to this day.

This information also appeared in western material, such as the official western Star Fox 64 website and also the Star Fox 64 Official Player's Guide, and was also mentioned again in a 2011 Nintendo Dream magazine interview with the development staff of Star Fox 64 3D, where Takaya Imamura reveals that the Great Fox was taken out to the original Star Fox team's investigation on Venom that resulted in James' death.

After the release of Star Fox 64 3D, Dylan Cuthbert and Q-Games had pitched doing a similar style of remake for the original SNES Star Fox title. However, this was turned down by Nintendo.

Contrary to popular belief, and also contrary to the Star Fox 64 Official Player's Guide, Solar is not a star, but merely a lava planet with an exposed mantle, according to both the official Japanese guidebooks for Star Fox 64 and Star Fox Command. Even the official Western Star Fox 64 website clarifies it being a planet. The Western localization of Star Fox Command would also reiterate this in-game, with one of its missions on Solar being named "The Red-Hot Planet".

In a 2011 Nintendo Dream magazine interview with the Star Fox 64 3D development staff, Takaya Imamura once again clarified that Solar is a planet, and that the star Lylat exists somewhere in the Lylat System not visible on the map screen. Apparently, the development team did consider changing Solar into being a sun for Star Fox 64 3D, but this was passed over.
