"She was not Makuta, but she was indescribably ancient and disturbingly frail in appearance. Her mask and armor were pitted and scarred from a thousand battles. She looked like a Toa, but her armor and mask design didn’t resemble anything Takanuva had ever seen before.”
I’m not a fan of the skinny Helryx interpretation many people seem to be going for. I think the in-story description makes it clear that her war torn appearance has a lot to do with her supposed “frailty”, not her innate frame itself. At the very least, it leaves it ambiguous enough to not make her thinner than any other toa. So I didn’t.
As for the armor that Takanuva couldn’t recognize, I took that to mean it should be something different from technic. I chose to go for more system pieces on the armor because he’s never seen system pieces on armor before, and because Helryx is the oldest toa, so she should have something bridging the gap between system and technic.
Here I present to you a toa of many battles and experiences.

I want to thank my brother WholesomeGadunka for giving me some tips on certain aspects of the build.
