These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
There is a clear line drawn down the center of the fanbase between the Krystal-lovers and Krystal-haters. Most pre-Adventures fans refused to accept her, though Adventures itself attracted a great many new (mostly non-Japanese) fans who found Krystal especially appealing.
Interestingly, this treatment also extends to her and Fox's (possible future) son, Marcus. Which is particularly noteworthy since he hasn't really done anything to be liked or hated to any real degree other than... be a potential outcome for the future of the series.
Broken Base: Several divisions divide fans of the series. Mainly between the ones that like the games that came after Star Fox 64 or not. Then there's the die-hards who consider the original Star Fox/Starwing to be the better game.
Contested Sequel: All of them. Even 64, as the SNES game has a sizeable fanbase. As mentioned above, don't try to start a discussion, especially if you get the unreleased Star Fox 2 involved.
Crack Pairing: One such pairing that has occurred is Wolf/Lucy. Shippers point to the appearance of Lucy's daughter in the ending "Goodbye Fox", claiming that she shares some of Wolf's traits.
Critical Research Failure: The description of Solar, which is a star, as "The Red-Hot Planet" in Command. Never mind that it's supposed to be the sun of the Lylat system, but given data on it places it as a Red Dwarf too cold to possibly sustain life, thus the fan theory that the Lylat System might be some kind of Binary Star system.
Draco in Leather Pants: The two mainstays of Star Wolf: Leon's (apparently) a cold-blooded killer, albeit one who loves flowers and rainbows, and Wolf is... Wolf. Panther also gets this a lot, as his great reverence for love thus redeems him.
Ensemble Dark Horse: Star Wolf, especially leader Wolf and Leon for their banter and Wolf and Leon's Badass nature and crazy personality respectively.
Panther is fairly popular because of his personality and being a cat he's used a lot as a subject in Nico Video as someone who is dancing, doing silly things, etc.
Lucy became the Ensemble Dark Horse of Command, despite getting the least character development of any of that game's new characters.
Various fan-theories attempting to explain James's sudden appearances at the end of 64 and Command. Likewise, the idea that James McCloud from F-Zero and this character are one and the same.
The argument that James and Fox were never renamed — they could be Fox James McCloud Sr. and Fox James McCloud Jr., or they could be James McCloud Sr. and James McCloud Jr. with "Fox" being a nickname.
Even Better Remake: Star Fox 64 made many, many improvements over the original stylish SNES Star Fox, and it's the most popular and remembered game in the series as a result of this.
Star Foxfanfics. Fox, Falco, Wolf, and Leon are sometimes portrayed as flaming gay. Of course, "Nymphomaniac Gaylords" are perhaps a more accurate description.
It doesn't help that, until Assault and Adventures, the cast was almost entirely male (With one un-determinable gender).
Executive Meddling: How Star Fox Adventures came to be, which began life as an unrelated Nintendo 64 game called Dinosaur Planet. There are two versions of this story, and the one you believe depends upon who you ask and how cynical you feel about modern game design, but both eventually result in the game's development schedule being drawn out past the end of the N64's life cycle and then being pushed to the upcoming GameCube:
Version 1 holds that while examining preview material for Dinosaur Planet, Shigeru Miyamoto was struck by the similarity of Rare's designs for the protagonist, Sabre (a wolf), to Fox McCloud. Miyamoto was reportedly so impressed with how the game was turning out that he called up the Rare development team and personally requested that they change the game to include Star Fox characters, and Rare agreed.
Version 2 is less amiable, and claims that while Dinosaur Planet was in development, Nintendo was working on an in-house Star Fox title of their own, one that used planetary exploration as a game mechanic, but which was also far behind schedule. Nintendo began searching their third-party dev projects for more complete games that could be modified to suit their needs, and upon noticing the similarities between Dinosaur Planet's character designs and those of Star Fox, pressured Rare to change the game to use the Star Fox setting and be ready as a launch title for the GameCube. This caused a split among the Rare leadership, half of whom wanted to obey Nintendo's wishes, and the other half who wanted to continue working on their own original IP. The debate dragged on so long that the N64 ceased production, which effectively ended development of Dinosaur Planet. Nintendo's strong-arming in this instance, combined with their low-key promotion of Rare's family-unfriendly Conkers Bad Fur Day, purportedly caused some bad blood between the two companies, ultimately leading Nintendo to sell their interest in Rare to Microsoft just after Adventures was released.
There's also the less popular Version 3, in which the Rare buy-out from Microsoft was actually done much earlier than it was publically announced. Rare was just going to finish Dinosaur Planet first. Nintendo didn't want Rare to have a brand new IP to bring to Microsoft, so they pressured Rare to change it to one of their own IPs.
The SNES Star Fox and Star Fox 64 were no exception to executive meddling. The European versions of the games were renamed Star Wing and Lylat Wars, respectively, because the creators of an 1983 Atari game, coincidentally named "Star Fox", had placed a trademark on the title in Europe, which, despite it never being released due to the failure of the system, it retained the trademark laws several years afterwards. Ironically, the meddling of the series name ended with Star Fox Adventures, it being the first Star Fox game to actually keep its name in Europe.
Fandom Heresy: Command is the worst game in the series regardless of almost every fragment you belong to, end of story. You can like it sometimes, but if you say it's anything but the worst you will receive a solid thwacking from the rest of the base.
With its predominantly male cast, Star Fox naturally gets this, especially in the form of Krystal the blue vixen, who is both Fox's love interest and the Base Breaker of the series as a whole. Some fans shunt her aside in favor of Fox/Falco and Fox/Wolf; there's also Fara Phoenix from the 1993 Nintendo Power comics based off of the SNES game as a replacement.
On the flip side, just about no one will even dare ship Panther with Krystal; lo and behold, rabid fans burst like crazy.
Star Fox 64's voice acting is legendary for the instant quotability and sheer Narm/Narm Charm of the many, many lines. Quoting ANY line from 64, even the smallest most incidental ones, will cause recognition and a quoting spree. To put it simply, every line in the game is a meme.
Assault's dialog isn't as good thanks to it being played more seriously, but Adventures has a few meme inspiring lines here and there.
Game Breaker: Wolf in Assault's multiplayer mode. He has the most health (the only character that can survive a hit from the Demon Spider) and SPEED.
Genius Bonus: Early artwork (and on the cover of) the first Star Fox game showed that the crewmembers of the Star Fox team all had metal casings on their legs. In real life, astronauts wear tight pants to stop the blood from rushing to their upper body to avoid passing out from the G-Force.
Panther's official last name in Japan is Caluroso. This spelling is used in Assault, Command, and Super Smash Bros. Brawl. In localization, however, his last name is changed to Caroso. Again, another translation mishap occurred in Command and changed his last name into Caruso. In the localization of Super Smash Bros Brawl, they used Caroso, confirming Caroso being the official last name for Panther outside Japan. Command has a large amount of translation errors. For instance, Panther speaks in third person in the English translation, yet speaks normally in other languages.
Dash's Japanese name is Ash. Dash is supposed to be a reference to a sci-fi movie character.
Doctor Andorf—er, Andross.
The ice planet in Star Fox 64 is Fichina, but was called "Fortuna" — an unrelated planet from the original game — in localization. The correct name is used in Star Fox Assault, since it includes both planets.
Also in Star Fox 64, planet Katarina was localized as "Katina" — and is still referred to as such in Assault.
Fox × Falco is the Fan-Preferred Couple in Japan and the principal Yaoi Fangirl favorite. They are also moderately popular in the West, but also tends to be almost diametrically opposed by Krystal fans. The couple's Fan Nickname is usually Falox in the West, and ファルフォ (Falfo) in Japan.
Fox × Wolf is the favorite in Bara Genre contexts, with Wolf usually being the more dominant one (in his Memetic Molester role). The Fan Nickname is usually Wolox in the West, and ウルフォ (Wolfo) in Japan.
Fox in the 1993 comics. He's not above losing his temper, arguing with people, and defying authority to get his way and he always turns out to be right — he was just Badass enough to get away with it. The Continuity Reboot also rebooted Fox's personality to a clean slate, and his personality was never quite the same after that, though both continuities involved variations of Cunning Like a Fox.
Some of the worse derailments of Krystal's personality in Command also qualify.
Killer App: The original game showcased the Super FX chip, which was necessary for its 3D graphics (the Super Nintendo was nowhere strong enough to do the necessary math calculations, so the chip handled that). The N64 version was the first major console game to feature force feedback vibration (other companies tried minor attempts, but it was Nintendo that really got it right and pushed it on the populace). This game also had extensive voice acting for a cartridge-based game, a massive technical achievement of its time.
LGBT Fanbase: The Star Fox franchise has a significant gay fanbase. The reasons are varied, but Ho Yay is a big reason that both Fan Yay and Yaoi Fangirls frequently share.
Memetic Badass: He has a catchphrase and a manly personality... and his face screams of "RAPE TIME!" Can you guess who?
Hey, Wolf's Assault voice is Engineer! Spy's sappin' my Landmaster!
Whatever sympathy the people of Corneria might have had for Andross went down the drain when he unleashed a bio-weapon on their planet. Then there's the issue with Vixy...
The Aparoids' attack on Sauria, later revealed to be a diversion to keep Star Fox busy while the Aparoids attack Corneria. And if that wasn't enough, they take over General Pepper and his flagship and force Fox to destroy him.
Pigma has only done evil things, but you can consider when he finally crosses it at multiple times. The earliest is in the backstory of 64, when he is bribed by Andross to betray James and Peppy. Later, one might consider his rubbing that in to Fox cementing him as pure evil. However, if 64 didn't convince you, he's WORSE in Assault. Wolf has kicked Pigma out of Star Wolf, and what does Pigma do when the Aparoids, who want to assimilate all life and technology, invade? He decides to become a leader of them and unleashes them on Fichina, letting it undergo an apocalypse thanks to them and infects the main building in order to procure an escape. Thankfully, he learns that Evil Is Not a Toy and is assimilated himself and is FINALLY Killed Off for Real. However, if the part in Command where he survives is considered canon...
It seems to have become a Parody Retcon, as when the 3DS remake was released, a new dub was created, with some of the original English voice actors reprising their roles, but the tone is made fairly silly and the memetic lines are left intact.
Never Live It Down: People like to refer to a certain VGCats strip for Homoerotic Subtext moments of the game... even though that was taken out of context and essentially non-existent in Star Fox 64. Now in later games it could apply, but in 64's wooden dialogue?
Nightmare Fuel/Tear Jerker: General Pepper's cries for you to kill him in Assault to prevent the Aparoids from taking over his body.
Recycled Premise: Assault's plotline is lifted more or less wholesale from obscure Treasure title Silpheed: The Lost Planet.
Recycled Script: In the comic series that was released at the same time as the original 1993 game, Slippy is kidnapped on Titania, but manages to rescue himself using his Utility Necklace. In 64, Slippy is kidnapped on Titania and has to be rescued by Fox. In Farewell, Beloved Falco, Slippy is kidnapped on Titania and has to be rescued by Fox again. Both scenarios involve the Landmaster, but in 64 it's used to rescue Slippy, while in Farewell Slippy is kidnapped while piloting it. (How does that guy manage to get kidnapped while driving atank?!?)
Slippy in Star Fox 64. He gets a lot of flack due to always getting chased by enemies and his annoying voice. These things were toned down in Star Fox Assault by making him a bit more competent as a pilot and by giving him a less-annoying voice and a couple funny lines here and there. He even managed to gain some fans.
Dash. Even Andrew is better-liked than him. Still, Dash was one of the more plot-significant characters of Command. Uncyclopedia's Star Foxarticle poked fun at this by saying Dash was played by Wil Wheaton.
Falco also gets some heat for his overly antagonistic comms chatter, including being an Ungrateful Bastard whenever you save him.
Seinfeld Is Unfunny: Star Fox for the SNES looks dated today, but it was considered one of the most advanced games at the time. Rendering Polygonal Graphics on the primarily 2D SNES is quite a feat to behold.
Sequel Displacement: Star Fox 64 was made with this intentionally in mind to replace the original Star Fox in the storyline.
So Okay, It's Average: Assault is widely regarded as this by fans and some reviewers. Interestingly, it's the worst-reviewed game in the series, but you'd be hard-pressed to find a fan that prefers Command over it.
Wolf's awful personality change in Command. Also, Super Smash Bros. Brawl has him act out of character at times, too.
Panther's severe change in speech (and even his surname) in Command.
Several characters inexplicably showing up with radically changed appearances or personalities (Krystal is either a cold heartless bitch or simply a hurt, yet forgivable woman scorned, depending on what path you take in the game).
Katt looks significantly different than her appearance in 64 and Bill has a Southern accent which he didn't have before.
Mostly Slippy, who tends to get in trouble very quickly. These guys may annoy players to the point where they may turn on their teammates just to shut them up for a while. To add insult to injury, in the cases where the team manages to be genuinely helpful, they may end up stealing important kills from you.
Sector Z in 64 was a big example of this. It's difficult to unlock medals mainly because the already thin number of enemies is shaved further by your teammates. They can get the last shots on those missiles. note In the original SNES version, their kills count towards your score, and Peppy and Falco could just as easily get into trouble as Slippy. The problem here is that your wing men have an infuriating tendency to fly right into your line of fire, so they end up bitching at you on the radio even as they're absorbing blasts that would have destroyed your enemies.
Lampshaded in Assault where Fox himself tries to help Wolf in the Aparoid Homeworld by giving advice, with Wolf only being annoyed and saying, "Keep your eyes to your front and your business to yourself, pup."
Due to being voiced by a woman in 64, there were quite a few people who thought that Slippy was female. Slippy is voiced by the same actress who voiced Katt. While it is obvious, she does do a distinct difference between them and her Slippy voice is pretty convincing. Lampshaded in Command when Falco is surprised to hear that Slippy is engaged to a woman.
Villain Decay: After trying to take over the Lylat System in Assault, Andrew's playing second fiddle to the Anglars in Command.
What Could Have Been: A borderline case. There are rumors floating around of a scrapped unlockable storyline path leading to a Golden Ending. If true, this was entirely shelved, as there is no evidence for it in the code (that is, Dummied Out has been Averted for once). According to the rumor on GameFAQs, the true ending would have elements of most of the endings, with Fox promising to get Star Wolf's bounty cleared, Krystal leaving both Star Fox and Star Wolf for an indefinite period of time to sort out her thoughts (with the implication that she would return to Fox), and the Star Fox team remaining together. Slippy also brought up heading to Aquas to be married to Amanda, and Dash shows up to mention that he will act as the warden for the terraformed Venom (with the implication that he will eventually turn out like Andross, as in the "Dash Makes A Choice" ending). In other words, the Golden Ending would resolve the Anglar threat while remaining wishy-washy about the character development over the game's course. Why this ending was scrapped is unknown, assuming that it ever existed.
