In fact, Unalak stands out among all the villains in the Avatar franchise. if for the rest, the fact that the avatar has passed into the avatar state is a death sentence, and you can only rely on luck or some other things, as Azula and the red lotus did, and otherwise they have absolutely no chance, then unalak is different. it is he who is the first and only character who, without any "buts" and "ifs", can defeat the avatar in a direct collision, and it is he who can make the avatar act smart. just remember the battle of Aang and Ozai. Aang, having become a puppet of past lives, crushed ozai with brute force, not paying attention to protection and so on. but if Aang tries to use the same tactics against unalak, he will break against the wall of superiority in strength. and if you look at it this way, then unalak is interesting as the only honest equal opponent among all these lottery players and those who need exactly 0.34 seconds in the avatar state. I would like them to make a remake of the battle of Korra and unalak, so that each of them shows the maximum of what they can before destroying Raava. and then all these "you won the battle, but not the war" are a little boring.
