My favourite Toa's will be Pohatu and Lewa, because Pohatu mask is the most similar to his 2015 form, and that's a good thing. Lewa looks good, but I don't get what his weapons are suppose to present.
Tahu, Onua and Kopaka masks looks weird and Chima-ish, but they still has some good pieces.
Gali is my least favourite, because the combination of Trans-blue with Orange won't look good, and her weapon is very boring and bland compared to others,
Overall opinion on the Toa - Looks ok and has some good pieces, but not as good as their 2015 form.
