I like them a lot, but it took me a while to understand their designs. They seemed a bit cluttered and very similar at first, given the short video.
Zamazenta is clearly a shield-bearing wolf knight, cape and feathered helmet and all, but Zacian took some time to understand...
Until I found the picture with Zacian's sword parts fusing, the same one that Benermerut just posted, which made it so much more clear.
Then, I noticed its long, flowing orange braids, and that all of Zacian's colours are not the same, but consistently lighter than Zamazenta's, and then it hit me:
Zacian looks feminine. It totally does! It's a sword-swinging wolf valkyrie with long braids and a skirt!
Wouldn't you agree? I'm not sure how many people noticed that.
Also, love the general epic-heroic theme they have. Can't wait to see their types.
