Hilde indeed wear Gold, but it's the first time she does. Absolutely nobody guessed she would be the first character. So Setsuka and Hwang can also wear some color they never wore just like Hilde did with Gold.I agree with you! Personally I believe in those colors... Here a prove: View attachment 70797

Hilde wears a gold/yellow armor and behind her is yellow, HaohMaru wears red bandages and behind is red, Setsuka always is assosiated with the pink color and the grey is for Hwang who his pants from his SCI outfit are grey and his belt and shoes are dark grey and if he returned he will look like his SCI appearance. It is only my opinion about this and maybe Ι'll be wrong, only the future will confirm this! And yes if Season 3 will happen, Lizardman/Aeon, Yun-Seong, Rock and maybe some of SCV characters Viola or ZWEI deserve to be in the game's roster.
