As a Bionicle Fan from the beginning , I was wildly disappointed with the 2015-2016 generation of Bionicle. I had so much hope for it at first cause it was Bionicle which meant to me there was going to be deep lore and mysteries that are hidden in plain sight, like how in the original Bionicle the Island of Mata Nui being a literal mask on the Great Spirit Robot's face was a secret that was always right there in front of us (On the Island of Mata Nui there is the Volcano called Mangai, the Mountain called Ihu, and the Bay called Naho. In Maori Mangai means Mouth, Ihu means Nose, and Naho means Eye Socket.)
I tried to eagle eye every detail of Gen 2 early in its release to figure out what the big secret would be this time! Turns out it was a whole lot of nothing but disappointment. I don't think the new writers really had a plan figured out at all, they were just hoping to bait us with nostalgia and hoped the older fans would do all the marketing to younger fans...It was kinda a big mess and may have killed any chance for Bionicle ever making another comeback, people don't want to stock a product that doesn't sell, and it's such a shame cause I felt like there was a story right there they could have gone with and neglected.
In the early Bionicle G2 animations there were hidden masks of Time everywhere in the background, the two legendary figures were both Mask Makers who's entire plot was based on Vakama and Nuhrii, and "Makuta" makes the "Mask of Ultimate Power" by combining all 6 elements much like how the Mask of Time was made from all 6 Great Disks from each Metru...
My conclusion was that this was an alternate Darker Timeline where Vakama had teamed up with Teridax and given him the Mask of Time.
Ekimu would have turned out to have been Vakama and secretly the real villain of the series misleading the Toa and the Villagers to stay in power, and "Makuta" was actually Nuhrii who had turned on Vakama's reign and was labeled the Villain in history. This time instead of trying to wake the Great Spirit the heroes would want to keep it from waking up because Mata Nui is long gone, the only mind that would be in there now is Teridax who somehow ended up Comatose here instead.
Maybe we would see other changed versions of characters like the remaining former Toa Metru and how they handled things after being betrayed by Vakama. If the script is flipped who might we see be unexpected allies?
