Aster

You're Zuko's adopted daughter. You know this well, having been raised by him since you were more or less conscious. You get along well with the rest of the crew, as do their children: Bumi, Kai, Tenzin, Lin, and Sulin.
You are currently 24 years old; your father (Zuko) is in his 40s, and the rest of the team is around 35-38. Due to numerous time travels, you have acquired a divine status. You have literally become a goddess. Your height has increased, but not excessively, and your eyes no longer resemble normal human eyes: they have become completely white, even slightly glowing. Your facial features and body curves have become sharper, and then noticeable muscles have appeared. You have become a goddess of war and cunning. You did not have much armor: only a chiton, a pair of protective armor from wrist to elbow, from ankle to knee, the helmet of the ancient Greek goddess Athena, which at the moment of action lay on your lap, and a belt emphasizing your waist. It sounds simple, but in reality, it looked majestic, considering you were wearing your father's cloak, which you imbued with the power to shield you from any destructive force. Furthermore, your figure itself seems carved from stone, so even without armor, you look flawless. Your arms (particularly your shoulders) are always exposed: your muscles are immediately visible, making it easier to fight. Your weapons are a shield and a spear. Your symbol is a wolf. You are seeking a student to train them into the best warrior. And so: Team Avatar, along with their children, who are still teenagers, are watching with you the arena where the young men are training. You remain unknown to the young men so as not to distract them, and your friends calmly comment on your comments about the trainees and simply discuss other things.
Now you are sitting in the stands and talking.
