Here’s a few headcanons for you.
Elemental color schemes
I don’t know what I’d “do” with this headcanon per se, but I’ve noticed that many or all of the non-Toa species we’ve seen have elemental color schemes. I first noticed this with Krekka, who has the colors of a Vo-being. Many - not all, but many - of the non-Toa sets that do not represent unique individuals have elemental color schemes, not just Krekka.
- Krekka, as mentioned, has Lightning colors
- Keetongu has Stone colors
- Sidorak has Fire colors
- Axonn has Magnetism colors (see next headcanon for more info)
- Brutaka has Psionics colors
- Takadox has Water colors
- Kalmah has Fire colors
- Carapar has Stone colors
- Mantax has Earth colors
- Ehlek has Air colors
- Pridak has Ice colors
- Nocturn has Plantlife colors
- Hydraxon has Earth colors
A component of this headcanon is that Skakdi had elemental colors prior to Spiriah’s tampering with the species. Vezon lacks an elemental color due to being only half a Skakdi - Vezok got the elemental part.
The main “meat” of this headcanon is that, for unclear cultural reasons, species that are not elementally-aligned wear elementally-colored armor. There may be social functions related to armor color - for example, in the Steltian lower class, Lightning-colored armor may denote guards (which Krekka was).
Headcanons on noncanonical element colors
Since it was discovered that Sonics and Magnetism lack canonical color schemes, I’ve got my own ideas.
- Sonics does have grey, so I thought yellow accents would go nicely with that, as it’s an underused color in BIONICLE.
- Magnetism is completely noncanon. I like the idea that it could be red and white, for two reasons. For one, it matches some popular depictions of magnets, with red bodies and white poles. For another, it matches some of the other secondary elements - Lightning is blue-and-white, and Plasma is orange-and-white. It sets a precedent for secondary elements to have white as their secondary color.
Now if only Sonics could be yellow-and-white, and Gravity purple-and-white. And Plantlife green-and-white.
Jovan's team
I like to imagine that the prototype Toa Inika seen in the German magazine are Jovan’s team, as well as the “Suletu”-wearer. Specifically, I think the “Suletu”-wearer is the one who carried the Kanohi Olmak.

Dume is racist (how Metru Nui got depopulated)
Also, I headcanon Turaga Dume as racist. That’s just my half-inflammatory, half-funny way of setting up the actual headcanon here, which is that Metru Nui was once home to possibly millions of Matoran before the population began to decline sharply under Dume’s Turagaship. Before Dume, the city’s demographics were much more diverse, with not only Matoran of all Elements represented but even many of the other species of the Matoran universe. Dume made a number of bad decisions that severely affected the living conditions in Metru Nui. Chief among these missteps is the failure of the Kralhi, who were replaced by the equally ill-informed Vahki (to little effect - they still destroyed swaths of the city on a regular basis). We also don’t know how many Toa existed in Metru Nui at this time, if any, making it a pretty dangerous place on account of all the homicidal Rahi. The attack of the Kanohi Dragon was a freak accident that still made his approval rating decrease, and sent many of the survivors of the battle packing. Tuyet begins her murder spree after the Kanohi Dragon attack as well, making the city appear increasingly hostile. At this point, the Dark Hunters are really making their presence known, and, after the Toa-Dark Hunter War, the Matoran who haven’t already left of their own accord are expelled by Dume. In my headcanon, he prejudicially orders all non-Matoran and secondary element Matoran to leave the city, including the Toa Mangai’s Toa of Plantlife. He believes that they are not “chosen” by Mata Nui, and thus do not deserve to live in his city. A couple thousand years later, the First Rahi show up and trash the Archives, leading to more casualties and migrations out of the city. Finally, at this point, Teridax takes over for Dume, and nobody notices because Dume has been doing such a bad job. That’s when the Morbuzakh is released, pushing whatever Matoran are left towards the inner city, and killing many of them. Metru Nui started out with millions of beings and ended with perhaps thousands of Matoran. On top of all of this, once the Great Rescue happened, there were enough Matoran on Mata Nui that having many Koro in each Wahi was necessary, with small villages spread across the island. When the Rahi attacked, the Matoran in these small villages were either killed or forced back to the main Koro, with the villages falling into disrepair and ruin over time. That’s why Metru Nui seems to have so many more Matoran than Mata Nui - a lot of them straight-up died. We even see some Matoran die in Mata Nui Online Game - Jaller loses contact with the North March (which could have, at one time, been an extra-Koronan village), and, when we arrive, the outpost is deserted, implying that the Guards stationed there have been killed.
Why Marendar will abandon their purpose
This one is pretty much entirely written by Pack. He pointed out that a major running theme in The Yesterday Quest is the rejection of one’s social role and prejudged identity. Chiara is a Toa of Lightning who isn’t particularly friendly, unlike most Vo-Matoran. Zaria is a Toa of Iron who not only survived the genocide of Fe-Toa, but broke the Toa Code and killed a Makuta. Orde is the only Ce-Toa who isn’t female, and he failed at his job to pacify the Zyglak. Gelu was once a Glatorian, but abandoned his role to become a caravan escort. Even the Vorox Kabrua rejects his societal role, surprising the Yesterday Questers when he speaks. Pack’s theory says that Marendar, who we know is sapient, will realize that they do not want to kill Toa, and will reject their purpose and identity just like the other characters of the serial. I really liked this theory, so I adopted it as a headcanon of what would happen.
Misc headcanons
- The map of the Matoran Universe shown in Makuta’s Guide to the Universe is so inaccurate because Teridax drew it himself based on info he’s overheard from the other Makuta. He was too prideful to ask them what their territories were like, or to ask for help on the map.
- The Energized Protodermis Entity did not manifest until after the Glatorian discovered Energized Protodermis. In fact, the Energized Protodermis did not even realize that it was alive or sapient until after it observed other sapient beings.
