It’s the strongest form of Mutation that exists, besides the Mask of Mutation. Which by the way can revert Roodaka’s mutation, which makes it in the same vein as Hordika Venom, which also keeps the color of a being:
" The user has control over how the target is mutated, which includes being able to undo other mutations such as those caused by Hordika Venom, Makuta Viruses and Roodaka’s Rhotuka power, but not those caused by Energized Protodermis. In theory, reversing a mutation is more difficult without detailed knowledge of the original mutation"
Which, as said above, can revert her mutations and also create irreversible mutations.
Savage does complicate this, but unless you have proof he isn’t a Toa of Stone, it would still follow the rule.
The Rahaga all share Orange eyes, leading me to believe this is connected to that mutation. Part of me is also thinking it has something to do with set design since it’s the strangest color to use instead of, like Grey or Black.
Because Mutation in the Matoran universe has never given Toa’s a new color before (Savage is only a possibility until confirmed to not be a ToS). Lesovikk didn’t turn purple from the Pit’s mutation. The Toa Nuva didn’t change their shade of color. Firedracax, while being the single most confusing mutation, is still a shade of red. Saying a concept doesn’t have rules would be disregarding the fact the 99% of all beings mutated keep their color, mutate their bodies and gain silver.
Wait where is this confirmed? Besides Savage, I haven’t seen another “maybe” or confirmed.
