!!Normal {{Trivia}}:
* AscendedFanon: "Nektann" was originally the name for turrets the Piraka used. When a warlord of the Piraka's race was introduced, a fan suggested that the turrets were named after him.
* ExecutiveMeddling: Averted with the first movie. A number of companies were approached by Lego, but said companies insisted on having the plot involve a [[FishOutOfWater human kid in the world]], as they thought that would appeal more. Lego instead listened to Greg Farshtey, who hated the idea, and kept looking until they found a company willing to work without human characters.
* FanNickname:
** "Fauxrok" or "Fohrok" for the fake Bohrok.
** "Kratana" for the Krana/Kraata hybrids.
** "Olda" for the Toa Nuva pre-transformation, before "Mata" was established as their team name.
** Nearly every wave of Matoran sets had a nickname that fans used. For example, "[=McToran=]" for the original Tohunga; "[=MoLtoran=]" for the ''Mask of Light'' Matoran; "Metruan" for the Metru Nui Matoran; "Voyatoran" and "Doomtoran" for the Voya Nui Matoran; "Mahritoran" for the Mahri Nui Matoran; and "Kardatoran" for the Karda Nui Matoran.

** Turaga Dume is voiced by Gerard Plunkett, who you might recognize as Babydoll's stepfather in ''Film/SuckerPunch'' and as Chief Coroner Bob Kelly in ''Series/DaVincisInquest''.
* PostscriptSeason: The web serials continue on past the toyline's cancellation and the main storyline's conclusion in ''Journey's End''. These serials use ideas that were originally meant for the main story before its abrupt cancellation, such as characters being stranded on Bota Magna, and characters searching for the Great Beings.
* TheOtherMarty: Toa Lhikan has a distinctly different voice in the trailer for ''Legends of Metru Nui'' than he does in the actual movie. It's doubtful that it was a placeholder, as all the other voices in the trailer are the same.
* ShowAccuracyToyAccuracy: The original trilogy movies took great liberties with the toy designs by making their biomechanical characters more organic, more "''bio''" -- they were given hands, mouths, muscles, and in the female's cases, a dose of AdaptationalAttractiveness. However some ended up only just very, very vaguely resembling their sets. Now, for the fourth movie, ''The Legend Reborn'', they decided to go the opposite route: making the characters extremely toy-accurate. Ridiculously toy-accurate -- some even retained the color-scheme ruining red connector rods. Ironically, the people in this movie were really supposed to be organic creatures with some minor mech-implants. Note that there is a ''lot'' of leeway. Many design traits could be interpreted in a myriad of ways. An interesting case is that of Roodaka's "[[TertiarySexualCharacteristics braids]]": rendered as strands of robotic hair in the movie, as tusks that moved together with her jaw in a video game, and as upward-pointing horns in the comics.
** Makuta in his set form wore a double-faced mask -- his mask in TheMovie didn't resemble either. So when the figure got re-released as part of the special edition Takutanuva set, it came with a special, movie-edition mask which had one of its faces re-sculpted to look like the movie design. This is in contrast to the "Ultimate Dume" exclusive set that came out the following year, whose special mask was designed to go with the figure's aesthetic, which already looked absolutely nothing like Makuta's look in that year's movie.
* SimilarlyNamedWorks: ''Web of Shadows'' is also the name of [[VideoGame/SpiderManWebOfShadows a Spider-Man game]].
* TrollingCreator: Not ''technically'' a LyingCreator, but you ''really'' need to watch out for ExactWords...
* UrbanLegendOfZelda: Voriki, Toa of Lightning. In 2001, there was a contest to create a BIONICLE fan website. Voriki was the product of one of those websites, which stated that Onepu was destined to become the seventh Toa. The site went mostly unnoticed until hints of an actual seventh Toa started to emerge; fans rediscovered the website and assumed it was a teaser, but needless to say they were quickly proven wrong. Voriki has become something of a [[MemeticMutation minor meme]] to the BIONICLE fanbase.
* WhatCouldHaveBeen:\\\
'''General:'''
** For starters, the entire franchise would have only lasted for one year, culminating in Mata Nui's awakening. Greg Farshtey, the writer of the comics, saw potential in the story, and convinced LEGO to keep it going. The line continued for another 9 and a half years.
** The original concept behind the series definitely fit the "''Boneheads of Voodoo Island''" WorkingTitle [[http://tinypic.com/view.php?pic=2eg8oqu&s=5#.U8zz00DYeXY crude, stereotypically "tribal" looking robots]] bashing each others' heads off. Test groups found this idea too disturbing, hence why the characters were given collectible masks instead that kids could knock off the toys. The visual design also changed to a more streamlined, robotic look, with the tribal elements reduced.
** The Toa were first envisioned as being these God-like entities that spoke in a constant dramatic voice. They were also to be of different age, Onua being the eldest and Lewa the youngest. Farshtey argued that this would make them too distant and boring, so they were eventually outfitted with wildly different personalities and talked like normal people. They were also made the same age, though Onua still was the wisest and Lewa still acted like a kid.
** Allegedly, making Gali a female was something of a last-minute decision. Originally, all of the Toa would have been male not that this kept the theme from suffering heavily from ViewerGenderConfusion.
** Every time the Toa won, they were originally supposed to dance. Effin' dance. The canceled Legend of Mata Nui game shows how this would have looked in its [[https://www.youtube.com/watch?v=kR6QA75bi9U final cutscene]].
** One idea Christian Faber had for the Bahrag queens is that they could have been GiantSpiders, carrying Bohrok in "ball-mode" on their back. While the eventual Bahrag sets more closely resembled theropod dinosaurs than arthropods, their non-canon combiner model returned to a [[FourLeggedInsect four-legged]] spider concept.
** A name the LEGO company considered earlier for the location of Mahri Nui was Ankor Nui. Another was Akua Nui.
** [[https://www.youtube.com/watch?v=xdkcjbInbRU This concept video]] tells us that the Mata Nui robot would have had the ability to roll up into a giant ball for space travel, a vortex would have lead to the "Power Plant" (Karda Nui), the prototype robot was to be only one tenth the size of the Mata Nui robot, as opposed to two thirds the size, Mata Nui's knee and three of his fingers would also have been islands, and while it's been known since '08, from another concept vid, it's worthy to mention that the Mata Nui robot has also been envisioned as a more organic-looking rock giant.
** [[http://faberfiles.blogspot.com Faber Files]], a blog by ''BIONICLE'' co-creator Christian Faber, based around very early concept art. Other subjects beside ''BIONICLE'' are touched upon, such as ''Toys/LEGOExoForce''. Among other interesting behind-the-scenes plans, the blog details what early ideas they had for ending '01, bringing the "Three Fingers" into play: the island, in reality Mata Nui's left hand, was to be the birthplace of the Bohrok when they were still called by their preliminary name, "Bugs". They would have drifted to the main island's shore much the same way as the Toa, and would have resembled spherical capsules with insect-legs. This idea was reworked into the hive-like Bohrok Nest setting under the main island, probably partly because the Three Fingers would have given away Mata Nui's nature too early.
** Originally, Mutran was going to wear the "Kanohi Artidax, the Mask of Mutation." However, the idea was scrapped after Greg Farshtey saw that the set wore a Shelek. The name is now the name of the island where Miserix was held. The Mask of Mutation was later given to Miserix.
** "Gatherers" was a name originally considered for the Bone Hunters, and is still reflected on some of the location names.
** ''BIONICLE: The Album''. Advertised on a teaser page in the promotional comics of '02, with names like Cold, Kenna, Music/RobZombie and Woven attached, fans were unsure of what to think of this strange new venture. Then the official website finally went up, containing a poll for various bands. Shortly afterwards, the entire thing disappeared. According to WordOfGod, LEGO and the performers didn't manage to come to a happy agreement over the promotion.\\\
'''Story:'''
** The sets and story originally planned for '10 and '11 (which is four waves, containing about 40-50 sets altogether). They scrapped all of this [[WrapItUp in preparation]] for the line's abrupt {{Cancellation}}, and released a wholly new line of merely 6, small-sized sets instead. That means no Element Lords, no shapeshifting assassin robots, no cyborg dinosaurs (although the basic setting has been recycled in ''Franchise/HeroFactory''), and no sequel to that "trilogy starter" movie that ends on a {{Cliffhanger}}.
** They had vastly different plans for the '06-'11 storyline originally too. '08 would have seen the continuation of the "Jaller and his team try to save Mata Nui's life'' arc (wrapped up in '07), followed by a multi-year story of the Toa Nuva trying to awaken him. The latter arc got compressed into '08, and instead of the originally planned happy ending, had a shocking DownerEnding[=/=]GainaxEnding.
** [[spoiler:The writer said he wanted to finish off the BigBad by having TheHero tear his chest open. This was deemed too violent, and thus the scenario was changed to part of his head getting crushed. Okay.]]
** Allegedly, the official UniverseBible contained so much potential story info that a lot of it never made it into the storyline. However the extent and exact details of these unused ideas is not known to the public.
** LEGO produced two special edition copper masks not made of actual copper, just colored like it. Their promotional blurbs claimed that they gave special powers to their wearer, but this point was later dropped, and the masks were introduced into the story as powerless decorative masks traditionally given to the winners of sporting tournaments.\\\
'''Toys:'''
** Some of the original, thankfully entirely scrapped prototypes looked like [[http://www.bzpower.com/story.php?ID=106 this]] googly-eyed monstrosity. It would have had articulated eyeballs.
** The [[http://biosector01.com/wiki/index.php/Sand_Tarakava Sand Tarakava]] never got through its prototype stage, however a total of five prototype Sand Tarakava model were indeed sold.
** The two Toa Hagah sets, Norik and Iruini, were designed to represent the Toa forms of Turaga Dume and the Dark Hunter Nidhiki, respectively. This is why their masks look so much alike. Reportedly, after a few seconds of looking at them, the Story Team decided to make them the Toa forms of two Rahaga characters, and rewrote their backstory from scratch.
** Traitorous Matoran and servant of [[BigBad Teridax]], Ahkmou was originally meant to have a new set coming out in '08, as a Shadow Toa. Plans were quickly scrapped, thus his only set remains his Matoran form from '04. He never became a Toa in the story either.
** Nuparu Mahri's set was supposed to come with an Aqua Blaster Blade, and it was even written into the books, yet the final model didn't include it. Instead, it only had a shield and a Cordak blaster.
** Similar to this, it was thought that Jaller only possessed one [[FlamingSword Energized Flame Sword]] until it was confirmed that he had [[DualWielding two]] in ''Prisoners of the Pit''. The reason for this was that Greg Farshtey was writing the story based off the Jaller toy's prototype.
** As revealed by German and Russian documentaries on LEGO, the Toa sets form the Mistika line had gone through a couple changes as well before finalization, mostly in the color scheme department. Insiders have also mentioned that their prototypes had resembled their original '02 sets better than the final models. There was much complaining.
** The 2005 playsets went through some particularly shocking changes before finalization. The Tower of the Toa set, for instance, was meant to come with a miniature Keetongu figure (at this scale, the same size as a regular canister set). In the finished set, a miniature Kahgarak spider occupies its place but it came with a gold-colored Mask of Shadows piece, so it's all good. The [[http://img4.wikia.nocookie.net/__cb20091209160558/lego/images/a/a4/8757_Prototype_Version.jpg prototype Visorak Battle Ram]] looks absolutely nothing like the [[http://images4.wikia.nocookie.net/__cb20120106181942/lego/images/c/cf/8757box.jpg final product]].
** The Manas were first envisioned having giant, bulging eyes, large teeth and grasping pincers. The finalized versions have teeny-tiny beads for eyes, no mouth and their pincers (which hardly look the part) can only poke.
** The Toa Metru were bare-chested at first. For the entire comic run, they were constantly drawn this way. The eventual sets, however, included a piece that covered their inner gear-mechanisms.
** Mata Nui's canister set was originally gold and ''white'', not gold and ''black''. As such, he is described as wearing white in one of the novels.
** The cover image for the '06 book ''Dark Destiny'' has a group shot of the six initial Piraka sets in their prototype forms. Most of them have only subtle differences from the released models, however Avak sports an entirely different head-design (he has pincers for cheeks), while Reidak has three eyes (also seen on the first promo-image for the '06 set-line, though [[WordOfGod the creators claimed]] those were [[ByTheLightsOfTheirEyes just random eyes belonging to no actual character]]). They even appear as such in the ''Voya Nui On-Line Game''. Fenrakk the spider also sports six legs in that game, whereas his actual set only has four.
** Hewkii Inika, the set famous for launching the color gray as a replacement for brown, was, apparently, originally meant to be brown itself, as evidenced by the non-canon on-line animations of '06, which show the character like this.
** Krika's set was envisioned with spikes that could be shot out of his back with a pressure-pump. In the actual set, this was abandoned and the concept carried over into the Nynrah Ghost Blaster, which he carried with a "third arm" on his back.
** A prototype for a sort of Matoran sphere-carrying vehicle shows up in the "behind-the-scenes" featurette on the ''Legends of Metru Nui'' DVD. No such model came out in the toyline.\\\
'''Games:'''
** ''Legend of Mata Nui'': They intended to make ''this'' the ultimate, full-canon telling of 2001's storyline. Then they scrapped it due to budget and time issues, and so the AdobeFlash-based ''Mata Nui On-Line Game'' replaced it as "''the''" 2001 ''BIONICLE'' game (and is still to this day for many fans "''the''" ultimate ''BIONICLE'' experience). In turn, the ''MNOG'' was meant to be just a little, non-canon side-note, which is why The LEGO Company gave such a free hand to its creators at Templar Studios, and it turned out all the better for it.
** ''MNOG'' was apparently designed with much more minigames in mind, as many characters throughout the game give the player instructions on how to defeat Kofo-Jaja scorpions, all the way to the final fight. Yet no such creatures ever appear in the game. The Sand Tarakava, Kane-Ra bull and Kuma-Nui rat is also mentioned, despite not appearing.
** There was to be a secret seventh tribe that lived on Mata Nui and worshiped the Makuta. Ahkmou, the evil bazaar trader, was supposed to stem from this tribe. In the MNOG, he was meant to hold a group of Matoran hostage, who would mass-produce the infected Comet balls. As with the things mentioned above, this was abandoned from the finished game, but there still is a strange, unused gamefile that shows a Ga-Matoran making Comets.
** The Le-Wahi chapter of the game would have played out differently. In the finished game, the player and the Le-Matoran (along with Taipu if you take him with you) are enslaved by a swarm of Nui-Rama, a Nui-Kopen wasp and an infected Lewa under Makuta's control. Originally, there was to be no Nui-Kopen present, and the slaves would have been kept there to serve as food for the Rama larvae but as Matoran Universe species can't reproduce, this had to be abandoned. In the game, Onua appears to fight Lewa apparently at random, but the developers originally wanted him to be summoned by Taipu, after you play a flute-song which he hears underground. The biggest change was the way Onua defeats Lewa not by hurling an electric bug at his face, knocking off the corrupted mask, but by punching him, fully intending to kill him until the Le-Matoran point out that Lewa is also a Toa. Not only would this have been overly violent, it would have created a plot-hole, since by this point in the story, Onua had already met Lewa.
** There were plans to release ''BIONICLE: The Game'' onto PlayStation, and it would have had levels featuring the six Toa in both their original Mata and updated Nuva forms, adding up to a total of 13 levels. A lot of these had to be scrapped due to the rushed development, even though the canceled levels were still heavily advertised in promotions. The released game only had 8 levels, and Tahu's the only one playable in both of his forms.
** [[http://www.youtube.com/watch?v=v6R_mc2oreU A game was planned for 2004]], but got scrapped very early in development. Outside of the linked videos, nothing is known about it.\\\
'''Movies:'''
** They had a movie planned to be released concurrently with the ''Legend of Mata Nui'' game. Yes, as in way back in 2001, when ''BIONICLE'' started. When both of these would-be storytelling sources got the ax, it was up to (yet again) little ol' ''Mata Nui On-Line Game'' to wrap up the plot. Not even the comics pulled that off, as they were meant to tie into the game/movie.
** Before Creative Capers and WangFilmProductions were hired, other studios (Who exactly, as of late, are still unknown) were also considered to animate.
** The directors of the first movie, ''Mask of Light'', talked about envisioning the characters with mechanical, switchblade-like hands, that could go from being claws to tools or other gadgets (mimicking the toys, which more often than not had no true hands to speak of). But as the plot never really called for them to have this ability, they were given normal hands with which to hold their stuff the normal way. Though Gali ''was'' shown to possess flip-out wrist propellers.
** The Lohrak were originally scheduled to make an appearance in Legends of Metru Nui, but they did not make it into the final cut, only appearing in the novelization. The same happened with the Troller Rahi. The Lohrak, though, later made a very brief {{Cameo}} in ''Web of Shadows'' (since they had their CGI models done), but it's hard to tell that it's them.
** Click the beetle, upon transforming into a shield for Mata Nui, would have stayed that way. But ''The Legend Reborn'' director Mark Baldo liked the idea of Click being able to switch between forms at will. His shield-mode face was also supposed to have just one huge eye on it, but in the movie, it has his whole face. Meanwhile the toy doesn't have a face at all.
** Relating to this, the Scarabax beetles' intro in the movie would have involved them eating the Vorox that attacks Mata Nui alive. There would also have been a quicksand scene in the film, which had to be cut as it would have been difficult to animate.
** Many fans have complained about the liberties the original movie trilogy took with the toy models, but when conceptualizing the ''Mask of Light'' movie, the creators originally did intended to go with toy-accurate character models, as evidenced by the early Lewa animation tests. Eventually, due to the figures' often ungainly designs and see-through holes, they decided to go with the style we see in the films, and fans had to wait 'till ''The Legend Reborn'' for a more toy-faithful animated movie.\\\
'''Books and comics:'''
** ''BIONICLE Legends: Invasion'' was a book that was scheduled to be released in 2007 as the seventh Legends novel. It was, however, canceled due to poor book sales. ''Invasion'' was meant to tell the story of the Toa Inika's trip down The Cord. Included in the book was a scene where Vezon slammed Matoro's head into a wall, a confrontation with a tribe of Zyglak, Vezon being taken by the Zyglak, Hahli being injured in a battle, Teridax possessing Matoro while the latter was using his Iden, stealing Hahli's Elda, and later being forced out by the other Toa Inika who threatened to kill Matoro's body. The book would also explain the relationship between the Zyglak and Krana. That information was released in the ''LEGO Magazine'' and ''BIONICLE: Encyclopedia Updated'' instead.
** Movie novelizations are also a rich source, as they are always written according to pre-finalization scripts. As such, while the novel for Web of Shadows describes Roodaka riding a giant flippin' mutant wasp out over the sea to where Makuta's imprisoned, the movie has no such scene, and she is simply shown walking around in a room, delivering exposition to herself.
** Because of various characters (particularly an ancient shapeshifter) being present in some canons and not others, the book, movie, and graphic novel versions of Legends of Metru Nui were all somewhat different, and the book, movie, and graphic novel of Web of Shadows were all significantly different, at the same time requiring fans to watch/read all three to understand all of what was going on.
** Graphic novel #10 would have told Mata Nui's journey through the Great Beings' maze in detail, but due to the low sales of GN #8 and #9, it never got made. It would have been the second graphic novel with fully original content.
* WhyFandomCantHaveNiceThings: Farshtey has stated he won't reveal the Shadowed One's name so he won't have to go through the same thing he went through with revealing Makuta's name.
* TheWikiRule:
** [[http://www.biosector01.com/wiki/index.php?title=Main_Page BIONICLESector01 Wiki]], or just [=BS01=] for short.
** [[http://bionicle.wikia.com/wiki/The_Bionicle_Wiki The BIONICLE Wiki]] is another.
* WordOfDante: [[WordOfGod Greg Farshtey]] will [[GodNeverSaidThat neither confirm nor deny the canonicity of this]], but when [[http://biosector01.com/wiki/images/a/a2/Art_Core_War.jpg a number of mysterious figures in dark robes]] appeared in the ''Mata Nui Saga'', someone suggested that they might be the Great Beings, and since then the fanbase has consistently depicted the Great Beings with this appearance.
* WordOfGod:
** GodNeverSaidThat: ''Deliberately invoked.''
** ShrugOfGod: mostly of the "Follow the story and find out" variety. Farshtey also refuses to explain [[TheTalk how new Matoran are made]], in order to preserve some mystique - and to avoid the inevitable {{Squick}} that would come from such a revelation.
** AscendedFanon: To the point where the fans (specifically, BZPower) can actually '''vote''' what happens in the story.
** TeasingCreator (see TrollingCreator and GodNeverSaidThat)
* WritingByTheSeatOfYourPants: Farshety has said this is his preferred writing style, at least for the web serials that aren't as connected to the main plot threads.

** [[CreatorsFavorite Overall favorite character]]: Kopaka
** Mask of Power: Kanohi Huna
** Characters to write about: Kopaka, Vezon, and Teridax.
** Book: ''BIONICLE Adventures 10: Time Trap'', which reimagined Teridax into the character he is now.
** Dark Hunter: Lariska
** Barraki: Takadox
*** Greg Farshtey based Takadox's personality on a character called "East" from one of his earlier novels.
** Matoran: Velika
** 2007 Matoran: Sarda
** Phantoka to write about: Mutran
** Mistika: Krika
** 2009 Character: Malum
** Set: he likes big and complex sets, but named his favorite as [[http://www.brickset.com/detail/?set=8940-1 Karzahni (8940)]] because it represents a character that he created by himself.
** Least: characters that use Treespeak, Vahki
** Least favorite storyline: Vakama's out-of-character FaceHeelTurn, which he had no say in, reportedly made him mad. He would have chosen Matau.
* Farshtey's ex-wife, Jackina, commonly assisted Greg with the ''BIONICLE'' story podcasts in offering her voice for the female characters, such as Hahli and Tuyet.
* Bob Thompson's (the former head of the original creative team behind ''BIONICLE'') favorite characters were on the dark side Roodaka and on the light side Matau. According to Greg, Bob disliked the Exo-Toa set and asked the writers to diminish its role in the story.
* Toa Nuva Lewa (in his 2008 "Phantoka" form) was comic artist Leigh Gallagher's favorite character to draw.
* The main ''BIONICLE'' logo is an image of the Three Virtues.
* The Spherus Magna system is in the shape of the Three Virtues' symbol.
* The Kanohi Kaukau was the only of the Toa Mata's Kanohi to have its design computer generated by set designers--the rest were done by carvings.
* Set-wise, the Kanohi Pakari is the most frequently used Great Kanohi, while the Ruru is the most frequently used Noble Kanohi.
* The term "Toa Mata" was officially coined after 2001-2002 story arc took place to prevent confusion. During this time, they were simply known as the "Toa" because they were the only Toa ever seen in the story at the time.
* Kopaka was the first ''BIONICLE'' character portrayed in the comics.
* A running storyline joke regarding Onua is his tendency to save others at the last moment. Examples include removing an infected Kanohi and Krana from Lewa, among others.
* Before the Maori lawsuit against The LEGO Group, the Shore Turtles were called Hoi and Bog Snakes were called Kuna.
* In the ''Mata Nui Online Game'':
** A carved stone at the Po-Matoran trader's stall reads: "My friend went to Po-Koro and all I got was this lousy rock."
** The music played when the Le-Matoran were preparing to attack the Nui-Rama Hive is "Music/RideOfTheValkyries", by Creator/RichardWagner.
** The walls of the Sanctum include packaging information from a LEGO set and a quote from Douglas Adams's ''Franchise/TheHitchhikersGuideToTheGalaxy'' series: "What do you get if you multiply six by nine?"
** The game contains numerous hidden messages {{foreshadowing}} the coming of the Bohrok, and indeed Mata Nui's true nature, which was only revealed 8 years after the game had been made.
* A scene in the ''Mata Nui Online Game'' depicts Lewa placing all six of his Kanohi on his personal Suva, and emerging with the golden mask; another scene depicts the Toa Mata's Kanohi simply transforming into the golden masks when they arrive at the Kini-Nui. However, the scene described in the book is the accurate one.
* The Toa's battle with the Manas is described as two Manas that are defeated by the two Toa Kaita in the book ''Tale of the Toa''. However, in the ''Mata Nui Online Game'', this battle is with a horde of Manas that are defeated by smashing control towers. In the canceled PC game, the Kaita also fight an entire Manas horde plus a Mana-Ko, but beat them in combat. Later canon combined these scenes: there were only two Manas, and the Kaita defeated them by targeting their control towers.
* ''BIONICLE Chronicles 1: Tale of the Toa'' was the first publication to show the Toa's battle with the Shadow Toa; this battle was originally going to be shown in the canceled PC game, ''BIONICLE: The Legend of Mata Nui''. Originally, Greg Farshtey wanted the battle to be won by having the Toa "absorbing" the Shadow Toa into themselves; Cathy Hapka, however, decided to have the Toa working together to defeat them with their Elemental Powers. However, Greg has said that his way is canon, and is referenced in the ''BIONICLE: Encyclopedia''.
* The Mata Nui Cow was originally called the "Mukau" ([[PunnyName a pun on "Moo-Cow"]]), but it has not been called by this name since 2001. The name was taken out of canon because the story team head considered it too silly.
* In an advertisement at the end of ''Powerless!'', there was information on the six Nuva symbols. The page claimed that Tahu's symbol was forged in the Mangai Volcano; Gali's drawn from Gali's Bay; Kopaka's as cold as Mount Ihu; Lewa's born of the living jungle; Pohatu's carved from the hardest stone; and Onua's a treasure from deep within Mata Nui. This is non-canon.
* In the ''Mata Nui Online Game'', Taipu and Hafu had their Kanohi switched. This caused confusion, as Taipu wore a Pakari in CGI images, but a Ruru in the game. He still had his Kanohi switched in the ''Bohrok Online Animations'' and the ''Bohrok-Kal Online Animations''. The error was eventually fixed in the ''Mata Nui Online Game II: The Final Chronicle'', with both Matoran wearing their respective Kanohi. There is a reference to this in the game when the player first talks to Taipu and he says he is always mistaken for Hafu.
* The Gukko was introduced in 2003 as a replacement for the earlier birds ridden in Le-Koro. These earlier birds, the Kahu and the Kewa, had to be written out of the storyline because of legal issues with their names. The change was explained away by the revelation that all three of these birds were in fact the same species, and had been called by different names in the past. Recently, it has been changed again to say that the Kahu and Kewa are subspecies of the main Gukko breed.
* The Naming Day concept was created by The LEGO Group when they were requested to change the names of several characters to avoid a lawsuit by the Maori people, who were angry that The LEGO Group was using words of their language. Some of the names changed were not from the Maori language, but rather from different Polynesian languages.
* The Mask of Elemental Energy first appeared in the non-canon ''BIONICLE: The Game'', although it has since been established as canon. The mask will not be used in any other form of media, since it was only intended as a power-up for the video game, although it did appear as an unlockable in ''BIONICLE Heroes''.
* The phrase "play well", LEGO's slogan and meaning of the company's name, is used in Kolhii.
* Graalok's facial structure in ''Mask of Light'' was based on the Kanohi Miru Nuva. This was done to accentuate the connection Lewa had with her and other wild Rahi.
* At the end of the credits of ''Mask of Light'', a small message in Matoran symbols can be seen. It translates as "No Rahi were harmed during the making of this film." This is a reference to when Jaller is about to kill Graalok the Ash Bear, but Lewa stops him.
* The USA today made ''BIONICLE Adventures 1: Mystery of Metru Nui'' #150 on their best-seller list. According to Greg Farshtey's Blog, it is the best selling ''BIONICLE'' book.
* A special sponge version of the Morbuzakh was released alongside a German ''BIONICLE'' magazine.
* The huge poster of Turaga Dume that Toa Matau crashes into in Ko-Metru has the Matoran writing for "play well".
* At one point, Matau mentions planning to have a "romantic ride-drive" with Nokama. This has been confirmed to be non-canon.
* Several Matoran who had a prominent role in ''Mask of Light'' have cameos in ''Legends of Metru Nui'', Takua, Jaller, and Hahli appear near the end, and Hewkii can be seen in the Coliseum.
* In ''BIONICLE: Maze of Shadows'':
** The Ash Bear is depicted using the Makuta Nui combiner model. The game exclusively uses sets and combiners and the Ash bear has no official model, so a model which had not, and still has not been seen in the story was used.
** While the Energized Protodermis Entity was described in ''Maze of Shadows'' as resembling a Toa Metru, in the game, the substance appeared to have the upper-half of Teridax's 2003 set incarnation, with a pillar of Energized Protodermis from the waist down. However, the Toa Metru form described in the book is considered the canonical form the entity took during the encounter.
* The Great Kanohi Ruru in Hordika form was the first Hordika head to be seen by fans (through the DVD version of ''Legends of Metru Nui''), although it was white and belonged to a prototype Toa Hordika Nuju set.
* On the cover of ''BIONICLE Adventures 8: Challenge of the Hordika'', Vakama's mask is identical in shape to a prototype Matau Hordika mask rather than his own. His eyes are also blue where they should be light-green.
* A line spoken by Matau makes a reference to Julius Caesar's famous sentence "Veni, Vidi, Vici": "We came, we scouted, we all-conquered!"
* The front and back of ''BIONICLE: Dark Hunters'' feature Keetongu and the Vahki, respectively. This was due to a printing error by Scholastic. However, the Keetongu error was retconned and explained by Greg Farshtey that it may have been a Dark Hunter "who had some sort of chameleon power" and "appeared as a one-eyed yellow Rahi" in The Many Deaths of Toa Tuyet. The Dark Hunter was later confirmed to be Triglax. The Vahki on the back of the book were explained, also. The Dark Hunters at some point captured some, and changed their command to serving them.
* A particular quote from the Shadowed One ("I think enough hands have been removed this year") was an allusion by Greg Farshtey to the excessive losses of hands during lightsaber combat in ''Star Wars Episode III: Revenge of the Sith'', which was also released in 2005.
* The Piraka.com is based in the Piraka Stronghold.
* Each Piraka had a promotional nickname:
** Hakann - "The Bully"
** Vezok - "The Beast"
** Zaktan - "The Snake"
** Avak - "The Trigger"
** Reidak - "The Tracer"
** Thok - "The Drifter"
* ''BIONICLE: The Quest Game'' gives the Toa Inika nicknames to go with the Piraka's. These names are non-canon.
** Hahli - "The Catcher"
** Matoro - "The Keeper"
** Hewkii - "The Hitter"
** Nuparu - "The Stopper"
** Kongu - "The Tumbler"
** Jaller - "The Striker"
* The ''BIONICLE'' team gave Nuparu a Mask of Flight because it would be humorous and ironic for a Toa of Earth, who rarely sees daylight, to actually fly, while Kongu, who lived in the treetops for most of his life as a Matoran, cannot.
* The reason why Greg Farshtey didn't want Matoro to have Elemental Powers in the story when he released his spirit is because it would give him an unfair advantage, since Matoro could attack beings who couldn't sense him.
* The music playing in the Toa Inika toy commercial is "''Move Along''" by the All-American Rejects, in accordance with the ''Free the Band'' promotion.
* A lawsuit was filed against The LEGO Group when a 2-year-old girl was frightened by a Toa Inika commercial, but LEGO won.
* The ''Voya Nui Online Game'''s files featured odd figures. It is still not known if they were a prototype of Hahli, or a Barraki prototype, as the figure appeared to have a Squid Launcher. Another picture showed the underwater city Mahri Nui.
* In some European countries, the Sea Squids are labeled as "Polyps."
* Since his transformation by the Pit Mutagen, Ehlek is sometimes referred to as "The Eel."
* Carapar only possesses one claw in the set, despite having two in the story.
* The markings on Pridak's face and weapons do not represent blood, as was once commonly believed. Greg Farshtey has confirmed them to be natural markings.
* Since his mutation, Pridak is sometimes referred to as "The Shark."
* In 2007, the [=BIONICLEStory=].com was set inside the Toa Terrain Crawler.
* The second Mask of Life code for ''Command Toa Matoro'' is former BZPower administrator and former BIONICLE.com Webmaster, Kelly (AKA Binkmeister's) initials. This was done as a thanks to all the work he had done to the site.
* The Nova Blast was first acknowledged in the non-canon ''BIONICLE: The Game'' as a "Nuva Blast," but was later included by Greg Farshtey as a part of the ''BIONICLE'' canon.
* ''BIONICLE: Rahi Beasts'' was mentioned briefly in ''BIONICLE: World'' as one of the books in the Order of Mata Nui's library, written by Rahaga Norik.
* [[http://www.bzpower.com/forum/index.php?automodule=blog&blogid=26&showentry=31095 Greg's thoughts on ''Dark Mirror'']]
* Gavla's immediate mutation upon becoming a Shadow Matoran was a case of artistic license on the part of the author. In actuality, Mutran would have altered her later.
* Antroz's poem about killing the Toa was based off the famous children's rhyme "Ten Little Indians".
* Mutran's name is derived from the English words "mutate" and "transform."
* The reason the comic version and the CGI version of the Keystone looks different is because Leigh Gallagher didn't have access to the CGI animations when he was drawing the comic. The CGI version of the Keystone is the accurate one.
* Vultraz's joke about clicking his red feet together in ''Brother In Arms'' is a reference to the classic movie TheWizardofOz.
* The Axalara T9 won the French "Grand Prix du Jouet" ("Toy Grand Prize") award in 2008.
* Jerbraz's name is based off Jeremy Brazeal, who was an artist for ''BIONICLE: World'' and the young readers ''BIONICLE: Journey of Takanuva'', ''BIONICLE: The Secret of Certavus'', and ''BIONICLE: Desert of Danger''.
* Tobduk's name is based off of Toby Dutkiewicz's name, one of the artists for ''BIONICLE: World''.
* Johmak's name is based off that of John [=McCormack=], an artist for ''BIONICLE: World''.
* Tren Krom was inspired by H.P. Lovecraft's character Cthulhu. ''BIONICLE'' writer Greg Farshtey stated this to be a "tip of the hat" to the author.
* Vezon's comment about his one-hundred ten unanswered questions in ''Destiny War'' is a reference to the large number of storyline questions Greg Farshtey receives via the personal messaging system on BZPower, some of which inevitably go unanswered.
* Greg Farshtey used Teridax's name as one of his ''WorldOfWarcraft'' character's names. He later deleted the character.
* Takanuva's possession of his Power Lance and Midak Skyblaster at the time were simply due to artistic license. The book could not be approved without Takanuva resembling his set counterpart, and thusly the weapons had to be included. He did not actually obtain them in the official canon until after the events of ''The Journey of Takanuva''.
* The prefix for Iron "Fe-" is derived from the chemical symbol "Fe" for the real element iron.
* The prefix for sonics "De-" was derived from the word "decibel," a real-world measurement unit for sound.
* The prefix for gravity "Ba-" was derived from words with the Greek origin of "baros", meaning "weight".
* The prefix for psionics "Ce-" was derived from the words "cerebral" and "cerebellum", words relating to the anatomy of the brain.
* Skirmix was named by former BIONICLE.com webmaster Kelly [=McKiernan=].
* When the My LEGO Network ''BIONICLE'' Campaign was first launched, the tribe of the Hero Agori was not identified. A poll was later held on BZPower to decide the tribal affiliation of the Agori, and Fire received the highest number of votes.
* In ''The Legend Reborn'', the diagram of Mata Nui is labeled in Matoran lettering. The diagram as a whole is titled "Mata Nui Robot", with individual diagrams labeled "front view" and "side view". A line pointing to Karda Nui identifies it as Mata Nui's "heart chamber". In the lower right-hand corner of the diagram the words "Bara Magna test site" are shown.
* Nektann's weapon was designed by Kelly [=McKiernan=], webmaster for BIONICLE.com. He was originally intended to have two, but the final set only included one.
* ''Bionicle'''s WorkingTitle was ''Boneheads of Voodoo Island'', ''Doo Heads'', but the title ''B4'' was also considered.
* Greg Farshtey wrote parts the first comic issue out of fun, and then turned them over to his higher-ups. Turned out they didn't have anyone else to write the thing, and as they needed to print the issue as fast as possible, they hired Greg immediately.
* Preliminary names for the Rahaga sets: Norik was "Tahkon", Iruini "Lahka", Bomonga "Nuukor", Kualus "Kuuls" and Pouks simply "Puks". The original names can be seen on the backs of the sets' instructions, which were for some reason never edited.
* The first mask piece to be designed was the Vahi, Mask of Time. It is unique in that it covers only the bottom part of a face, as opposed to almost all other masks, which conceal the entire face. Despite being the oldest, it's not easy to acquire -- the piece was to be packaged together with the canceled ''Legend of Mata Nui'' PC game, and was later part of a number of promotions or exclusive sets, but [[NoExportForYou these weren't available globally]].
* The names Papu and Rangi come up at some points in the ''Mata Nui On-Line Game''. After showing Nuju's letter to Nokama, she will say "Papu and Rangi have great plans for you" in response to the question "Who am I?", even though every other time she merely says "someone". In the German version of the game, Jala also mentions them as being the founders of Ta-Koro -- the English version omits this part. The names are complete mysteries, and haven't come up anywhere else. ''BIONICLE'' writer Greg Farshtey commented that they must have been made up by the developers. Polynesian mythology (on which the brand's early story was based) contains similar-named entities (Papa the Earth goddess and Rangi the sky god), so this is probably where they got the ideas for them.
* In the ''Mask of Light'' movie, the message inscribed inside the titular mask reads "Technic Organic Apps One Destiny". With the first part [[FunWithAcronyms reading "TOA"]], it could be a reference to the old "Six Heroes, One Destiny" tagline.
