A rather abstract rendition of the toa, just to represent their color schemes and general aesthetic.
Le-koro, I imagine the Le matoran living close to the sky, on the central mountain of the island.
Po-Koro, a controversial choice, I think Pohatu should become the toa of nature, and as such Po-Koro would resemble a combination of g1’s Le and Po koros.
I really do apologize for how ‘abstract’ this looks, I did make these rather fast, regardless I hope you can get the gist of what I’m trying to convey.
Feel free to discuss.
