Nidhiki wasn’t the only Toa who joined the Dark Hunters; there were also other Dark Hunters who were once Toa themselves. Two of them are Spinner (another former Toa of Air) and Savage (a former Toa of Earth), whom we don’t know the full backstories of before they joined the organisation.
All we know is that Spinner was severely injured in an attack by mutated Rahkshi and was modified by the Dark Hunters and Savage was mutated into a Toa Hordika by the Visorak, which made him go insane.
I’ve been thinking about this recently and I thought of a headcanon for which teams Spinner and Savage were a part of before they became Dark Hunters that I would like to share with you guys.

Before that, however, I can’t talk about Spinner and Savage in this headcanon without mentioning the Toa Hagah, whom we know of due to Norik and his team. They were not the only Toa Hagah, however; there were other teams of these elite Toa who were commanded by seven members of the Brotherhood of Makuta, one of whom was Chirox, the creator of several Rahi species, including the Visorak; and Mutran, who created the Shadow Leeches.
The relationship between the Toa Hagah and the Makuta was shattered when Norik and his team learned about the Brotherhood’s crimes and their alliance with the Dark Hunters. This resulted in their rebellion in which they took the Kanohi Avohkii and the Makoki Stone, but not before being turned into Rahaga.
This raid made the Brotherhood fear similar revolts from the other Toa Hagah, which prompted them to purge their Toa servants by killing them (Chirox, instead opting to use several of them for developing Rahi).

Norik’s team are the only Toa Hagah that we know the names and history of. Nothing much has been revealed about the other Toa Hagah that served their Makuta commanders. It’s possible that others may have survived, with some of them even joining the Dark Hunters.

Which now brings us to my headcanon for Spinner and Savage.
They were two of the other Toa Hagah who served the Brotherhood of Makuta, with Savage serving Chirox, which explains his mutation into a Hordika, and Spinner serving under Mutran, who - in this headcanon - also created the mutated Rahkshi before going on to create the Shadow Leeches.
Because Savage and Spinner were unaware of the Brotherhood’s activities, they and their respective teams were caught completely by surprise by the purge. If these two former Toa ever met at one point while serving the Brotherhood, then they certainly didn’t recognise each other when they joined the Dark Hunters.

That’s my headcanon for Spinner and Savage before they joined the Dark Hunters. What do you all think?
