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.

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.

In the Japanese version of Star Fox Adventures, some of the dinosaur tribes have different localized names from their original names. For example, the CloudRunners are referred to as the クラウド族 (Kuraudo-zoku), which translates to "Cloud Tribe". The EarthWalkers are referred to as the アソーカ族 (Asōka-zoku), which strangely seems to translates to "Ahsoka Tribe". "Ahsoka" is a name of Sanskrit origin that means "pure and hopeful".

In Star Fox: Assault's Sauria mission, Peppy curiously refers to the CloudRunner Tribe as just "the Cloud Tribe". This makes more sense when you factor in that that's what they're called in the Japanese version of Star Fox Adventures and thus was what the original script writers for Assault in Japan used as a frame of reference, and it appears that whoever was localizing the script for western audiences didn't bother to change it back to the original Rare name.

Funny enough, in Star Fox Command, Krystal pilots a spacecraft that is both shaped and named after the CloudRunners. In the Japanese version, it actually retains that name, クラウドランナー (Kuraudoran'nā), which means that Command marks the first time Rare's original CloudRunner name was utilized in the Japanese version of these games.

Star Fox Adventures had a Circuit City-exclusive "survival kit" pre-order bonus which contained "Fox Fuel" soda, a door hanger, an air freshener for cars, temporary tattoos, and most unusual of all, toilet paper with tips for the game written on it.

While merely referred to as the King EarthWalker in the final Star Fox Adventures, voice clips from Dinosaur Planet on the Nintendo 64 indicate that he was intended to have a name: "Albada". Both the Queen EarthWalker and Sabre have voice clips that refer to him as such.

Star Fox Adventures primarily takes place on a planet filled with dinosaurs known simply as "Dinosaur Planet". It would return or be referenced in future games like Star Fox Assault and Star Fox Command, as well as "Star Fox Zero - The Battle Begins", a promotional anime released to commemorate the release of Star Fox Zero, but it would instead be referred to with a different name: "Sauria".

It turns out Rare had always intended Dinosaur Planet's real name to be Sauria, as leaked voice clips from the implied climax of the original Nintendo 64 Dinosaur Planet feature the Krazoa name dropping it as they begin the alignment of the "Majestic Eight" planets to wreak havoc on the universe using the power of their god, the Quan Ata Lachu. An edition of "Ask Uncle Tusk" on Rare's old website revealed Dinosaur Planet's name to be Sauria as well.

Star Fox Adventures began development as Dinosaur Planet, which originally began development as a direct sequel to Diddy Kong Racing, starring Timber the Tiger (who himself was intended as the main character of DKR when it was Pro-Am 64, before Donkey Kong characters were incorporated into it). It was pitched as an adventure/racing hybrid where Timber, equipped with a rucksack, little fingerless gloves, and a baseball cap would go back in time and team up with a younger version of Tricky, a boss from the first DKR. Wizpig, the main antagonist and final boss of the first Diddy Kong Racing, was also involved. It would seem a working title for this iteration of the game was "Dino Island", going by several posts on former Rare employee Ed Bryan's Twitter account.

Eventually it was decided to rework the concept into an entirely new original IP with no story connections to DKR and two new main characters, named Sabre and Krystal, and also make it a full-on action-adventure game directly inspired by The Legend of Zelda: Ocarina of Time. DP/SFA's various racing segments are said to be remnants of the original DKR successor concept, and while he retained the name of the DKR boss (something Rare seems to regret), Tricky would wind up becoming his own distinct character. Several files within DP/SFA's data also mention Timber, obviously a remnant from when he was the star.

Sabre and Krystal were in turn eventually replaced by Fox McCloud as the main playable character when the game was rebranded into what we know today as Star Fox Adventures, though Tricky would remain as his sidekick and Krystal would remain as a main character.

Many fans today recognize Star Fox Adventure's Shopkeeper's name as "Shabunga". However, the game's development team never intended the Shopkeeper character to have a name, even as far back when it was still Dinosaur Planet.

"Shabunga" was initially the name of a cut NPC character from Dinosaur Planet, a mutant creature that Sabre/Fox and Tricky would come across in an area known as Willow Grove, the bridge between SwapStone Hollow (ThornTail Hollow in SFA) and Dragon Rock, which was becoming a strange and mutated land as a result of General Scales' and Drakor's actions within the latter area, which was also mutating its inhabitants. As such, Shabunga, and supposedly other mutants according to the Dinosaur Planet condensed story (though none appear in the leaked December 2000 build) were cast off and sealed away within Willow Grove by the ThornTails that lived in SwapStone Hollow, frightened by their now warped appearances.

This mutant character was said to be an alchemist and also one of the SpellStone guardians, and thus was required to revitalize General Scales' Kamerian Belt (or "Krazoa Star" as Shabunga puts it), to allow Sabre and Tricky to enter the mutated wasteland Dragon Rock unharmed, and would later be required activate the SpellStone acquired from defeating Dragon Rock's boss, the Kamerian Heart.

With Willow Grove removed in the final game, Shabunga would appear in SFA as an enemy type known as the "FireCrawler" that appears in Moon Mountain Pass and also all over Dragon Rock. His role as the SpellStone GateKeeper of Dragon Rock would then be given to a generic quiet ThornTail that resides in ThornTail Hollow.

Curiously, SFA's Nintendo Power guidebook and also official English website would both re-appropriate the mutant's name to the Shopkeeper, claiming his name to be "Shabunga", despite the actual game just merely referring to him as the Shopkeeper. It turns out there's a reason for this: looking at the Japanese localization for Star Fox Adventures, it appears that NCL did indeed repurpose the "Shabunga" name behind Rare's back for the Shopkeeper as he's called that both in-game and also all over its ancillary material. For example, in the Japanese version of SFA, the ThornTail Store is renamed to シャブンガの店 (Shabunga no mise), which translates to Shabunga's Shop in English.

Another notable example is when Fox is talking to the Blue SnowHorn in SnowHorn Wastes; in the English version, the latter has this to say:


Retranslating the Japanese subtitles in the Japanese version of the game, however, reveals:


It would seem that whoever wrote the Nintendo Power SFA guide was given the memo about this.

Since Star Fox Adventures was in development at the same time as Melee, the cast of Adventures would voice Fox (Steve Malpass), Falco (Ben Cullum), and Peppy and Slippy (Chris Seavor) within the English versions of the Corneria and Venom stages in Super Smash Bros. Melee, despite both stages being based on Star Fox 64.

Concept artwork for the ShopKeeper, Shabunga, shows him to be more corpulent than compared to how he appears in the final game.

There is evidence in the game's data that General Scales was meant to have a full battle with both Fox and Falco, but it was cut from the final game.

Star Fox Adventures was at one point called "Star Fox Adventures: Dinosaur Planet". This name referenced both original incarnations of the game, Rare's "Dinosaur Planet" and also Nintendo EAD's "Star Fox Adventures" that was in development around the same time; both ended up being merged into the same project, hence the original title, though sometime before release, the "Dinosaur Planet" subtitle was dropped, leaving the final game named as just Star Fox Adventures.

Curiously, when looking at Star Fox Adventures save data on a GCN memory card through the Wii, it actually includes its original "Dinosaur Planet" subtitle, as well as using the Star Fox emblem present in the beta logo for the save data icon. This was not the case in the GameCube's data card management menu.

Star Fox Adventures was originally a game called "Dinosaur Planet" and was unrelated to the Star Fox series. The game featured Krystal as the main protagonist and was to be for the Nintendo 64.

When Shigeru Miyamoto noticed the similarities of the characters to Star Fox, he asked Rare if they could change it, resulting in Star Fox Adventures.
