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).

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.

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.

The Blue Marine, the submarine used in only the Aquas mission, is the only vehicle utilized by the Star Fox team in Star Fox 64 to not have been designed by Space Dynamics. It was instead a personal project designed by Slippy Toad, who scrapped it together using discarded parts. He also used maintenance Arwing parts, such as the laser cannons and rolling mechanism.

This information also appeared in the Star Fox 64 Official Player's Guide. However, it would also bolt on the fact that Beltino Toad, Slippy's father who was first mentioned on the Japanese website for Star Fox 64, helped him create it.

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.

Titania, being called the "Forbidden Planet", is the only stage in all of Star Fox 64 to not feature any of Andross' forces. Instead, all of the enemies and defense systems, including the boss Goras, are said to be remnants of an ancient alien civilization, with Goras being said to be a bio-weapon the ancient people modified before they went extinct. The official Japanese Star Fox 64 guide (as well as the Star Fox 64 Official Player's Guide) hints that the underwater ruins seen in the oceans of Aquas are connected to the ancient ruins on Titania.

As it did for Bacoon and the underwater ruins of Aquas, the Star Fox 64 Official Player's Guide would expand upon Goras' and Titania's backstory, claiming that it was formerly a green lush planet, and that the ancient people who lived there were an advanced agrarian civilization that would leave behind their harvests at temples that existed in each town to appease Goras. It claims that the civilization was destroyed by an asteroid colliding with Titania, leaving Goras as the only surviving creature on the planet that was now a barren wasteland, and it also claims that it was modified by Andross.

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.

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.

One of the enemies that appear on the Zoness stage, according to the official Japanese Star Fox 64 guidebook, is known as オブネマ (Obunema), or Obnema, a giant anthropod that can only be defeated with charge shots.

The Star Fox 64 Official Player's Guide renames it as "Kani" and claims that prior to Zoness' devastation, it was a favored delicacy in Zoness restaurants.

The Star Fox 64 Official Player's Guide gives Aquas' boss Bacoon a very different backstory from the official Japanese guidebook. The latter says that Bacoon is simply just a bioweapon made by Andross, but the former gives it a more elaborate background, claiming that it was an ancient monster that was jealous of the ancient civilization and their temples/islands above the ocean's surface, and overtime it learned how to control the other aquatic lifeforms within Aquas' oceans, such as the explosive Starfish, which were then commanded by Bacoon to migrate to the ice cap and detonate, resulting in the polar cap being melted and all of the islands submerged into the sea forever, essentially explaining the ancient undersea ruins throughout the Aquas stage.

Prior to his days as Star Fox's ace pilot, Falco Lombardi was originally a member of a space gang known as "FREE AS A BIRD". Katt Monroe was part of this gang as well. In a 2011 Nintendo Dream interview, Takaya Imamura revealed that when Fox was forming his new Star Fox team in the wake of James' death, he heard stories about how good a pilot Falco was as apart of FREE AS A BIRD, and visited him multiple times to try to convince him to join his new team, as he wanted to have an experienced partner due to still being unsure of himself as a leader.

Though originally mentioned in the background lore for the Japanese version of Star Fox 64, FREE AS A BIRD in its entirety would physically appear in "Farewell Beloved Falco", a canonical manga interquel set between Star Fox 64 and Star Fox Adventures that was never localized outside of Japan.

According to the official Japanese guidebooks for both Star Fox 64 and Star Fox Command, Meteo (or "Asteroid Belt" as it's referred to in Command) is said to represent remnants of a destroyed fifth planet from the early days of the Lylat System, which aligns with its close proximity to Corneria, the fourth planet of the Lylat System. It is said that many of the asteroids there contain highly pure metals, and their outer edges have been the site of high-quality mineral deposits, though ultimately what lies in the deepest parts of the asteroids remains unknown.

This information would also appear on the official western Star Fox 64 website and also in the Star Fox 64 Official Player's Guide, though strangely enough, the latter states that Meteo is believed to be the remnants of a ninth planet from the early days of Lylat.

According to the official Japanese Star Fox 64 guidebook, Area 6 was originally a space farm or plantation before Andross' army invaded and turned it into a military base for their forces.

At the beginning of Star Fox: Assault, Andrew Oikonny's rebellion is seen to be utilizing three models of humanoid mechas, which, going by the official Japanese guidebook for Star Fox: Assault, seem to be known as サルデス (Sarudesu). This can be transliterated as "Sardes".

• サルデス MK III S (this seems to be a prototype, judging by Fox's comments. It later appears infected by the Aparoids.)
• サルデス MK III DB
• サルデス MK III DG

These are actually meant to represent evolved forms of the Shogun Warriors featured near the end of Star Fox 64's Sector Y stage, who too in the Japanese version of SF64 are referred to as サルデス (Sarudesu). What is called the Shogun Lord in the English version of the game is also called サルデスII (Sarudesu II) in the Japanese version.

As サル (Saru) is the Japanese word for monkey, and デス (Desu) means death, the literal translation of the name in English should be "Monkey Death".

Star Fox, Star Fox 64 and Star Fox Adventures are the only Star Fox titles to provide official ages for the main characters, primarily within their Japanese ancillary material. In the Original Soundtrack box released for the first game, Fox, Falco, Peppy and Slippy are said to be 25, 28, 36 and 19 respectively. Star Fox 64, being a remake of the first game, would retcon these ages and make Fox 18, Falco 19, Peppy 41 and Slippy 18.

The "Farewell Beloved Falco" midquel manga, which is set right in the middle of the eight years between Star Fox 64 and Star Fox Adventures, also gives the original Star Fox crew ages, with Fox now being 22, Slippy 22, Falco 23, and Peppy 45.

Star Fox Adventures takes place eight years after Star Fox 64, which means that Fox is now 26, Falco 27, Peppy 49 and Slippy 26. Japanese Star Fox Adventures ancillary material also reveals Krystal's age to be 19, making her distinctly the only Star Fox character outside of the original four Star Fox members to have a known age. Going by this, she would be 11 and 15 years old during the events of Star Fox 64 and Farewell Beloved Falco, respectively.

After Adventures' release, Nintendo, specifically Takaya Imamura, made a deliberate decision for future Star Fox games to not provide any official age numbers for any of the characters. However, Star Fox Assault officially is said to take place only year after the events of Star Fox Adventures, so this would make Fox 27, Falco 28, Peppy 50, Slippy 27, and Krystal 20. Similarly, according to Takaya Imamura in a 2007 interview, Star Fox Command takes place 2-3 years after Assault, which would make Fox 29-30, Falco 30-31, Peppy 52-53, Slippy 29-30, and Krystal 22-23.

Although Wolf O'Donnell has never had any age officially listed for him, Takaya Imamura implied on Twitter that he is within the same generation of Peppy and James.

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.

The boss on Solar known as Vulcain, alternatively known as サンガー (Sangā) or Sanger in the Japanese version of Star Fox 64, was originally intended to be the boss for Sector X.

A developer story on the Japanese website for Star Fox 64 reveals Sector X was originally meant to be the "Andross Army Biological Weapon Development Factory", and Fox and his crew were supposed to have engaged with a transport fleet heading for the factory, where they would sneak past the security defenses and enter the interior of the factory, only to find it in a state of disarray due to an accident during an experiment with robots and out-of-control bioweapons attacking all over. They would eventually come across an enemy transport ship attempting to escape only for it to be suddenly destroyed from the inside, revealing Vulcain as the stage's boss.

In the final game, Spyborg (HVC-09 in the Japanese version) is the boss of Sector X, and Vulcain was relocated to planet Solar. Vulcain's beta textures from its tenure as the Sector X boss was recently discovered within files pertaining to Star Fox 64 in the Nintendo Gigaleak.

The official Japanese Star Fox 64 guidebook reveals that Pigma Dengar, who became a subordinate of Andross, was effectively the real mastermind behind the creation of Star Wolf: he goated and manipulated Wolf into becoming its leader and also working for Andross as a means to combat the newly formed Star Fox team led by Fox McCloud, taking advantage of Wolf's supposed honorable, "magnaimous" side and also his prior rivalry with Fox's father, James McCloud. It is said that he manipulates the entire team behind the scenes in accordance to Andross' orders. It also reveals that Pigma had already been working underneath Andross during his time as a researcher at the Corneria Defense Force Scientific Research Institute. It's also revealed that both Pigma and Andross had custom engineered the Wolfens that the Star Wolf team utilize in their battles against the Star Fox team's Arwings.

In Super Smash Bros. 4, the trophies for Pigma and the Wolfen would reiterate this information, as would the official guidebook for Star Fox Command. The Star Fox 64 Official Player's Guide would similarly allude to Pigma being the root cause of Fox and Wolf's rivalry, claiming that, without his influence, perhaps they could have been friends in another timeline.

Prior to Star Fox Zero, there were two attempts in previous installments to revitalize the concept of the Walker from Star Fox 2, or at least the idea of the Arwing transforming into a robot form, those specifically being Star Fox 64 and Star Fox Command, games that both aimed at preserving ideas from the then-long-lost Star Fox 2.

• For Star Fox 64, according to Shigeru Miyamoto in an interview at the end of the Star Fox 64 Official Player's Guide, he wanted to have the Arwing transform into "a human-type craft". This was rejected by other staff members of the SF64 development team. In response, Miyamoto told his team to come up with better ideas, and from there they created the Landmaster and Blue Marine for additional vehicles.

• For Star Fox Command, according to Takaya Imamura in an interview in 2007, the dev team experimented with having the Arwing and other spacecraft transform into robots, but this was ultimately dropped.
