Let’s be fair, a lot of Bionicle’s canon information isn’t exactly enshrined in law. Most of it is just “Things the writers didn’t think about until some kid asked a leading question about it on BZP/the LMBs, at which point Greg threw together a quick answer that was probably contradicted by one of the actual books, and also a previous Greg post that Greg himself forgot about.” That’s how you end up with Helryx, the Mata build who is completely unrecognisable to Takanuva, who is also a Mata build, and knew all six of the only other known Mata builds in the universe.
The Bionicle fandom’s obsession with having every detail 100% confirmed by Greg has done it absolutely zero favours, because it’s ended with things like “There are two separate universes, the set/game/comic/Advance/Ghost universe where the characters have magnetic plates for hands, and the book/movie universe where they have fingers” because Greg decided to say that the toy designs were 100% canon with zero alterations, except his own books depict the characters with digits.
I do care about Bionicle canon, but it’s a bloody great Quantum Canon, where everything makes sense as long as you aren’t looking too closely at it. But the moment you start scrutinising it, it all collapses into a self-contradictory mess, because the guy that wrote it didn’t like doing plans, played favourites with the characters, and had to use a wiki to keep abreast of the lore. A wiki that uses his posts as their primary references for everything. And unfortunately, the Bionicle fandom insists on going over the entire lore with a magnifying glass.
I got aa lot of respect for Greg. He’s answered far more fan questions than he should ever have been expected to. But this is a guy who has admitted to having aphantasia, to being unable to visualise things in his head, and then we sit here and go “But what does this character look like?”
He doesn’t know! He’s never known! He has a rough idea of muscle mass and maybe colour, and that’s it. And I’m not knocking him as a writer. He did an absolutely brilliant job with most of the books, comics, all the serials before the middle of 2008 and a handful of the ones after that, and anything else I’m forgetting. But he didn’t have any idea what the non-set characters looked like. And most of the lore questions he got would’ve been things that he never considered.
Basically:
Also like, there’s a full two years of stuff we just don’t have access to anymore because of the Dataclysm. It’s not even in the Archives, it’s just gone.
Also all three contests have changed canon and gone against Greg statements in either big or small ways.
