Actually, spoilers:end of spoilers
Azula is the big bad of that storyline, she escaped in a previous story after they found hers and Zuko's mom, and now she's back a healthy brand of insane. Like she's happy and badass again but clearly still Cray-Cray. But now she's just trying to help Zuko be the best Fire Lord he can be. ...which is kinda horrifying when you think about it.
That pig is way more of a troll than in Power Rangers. Neat.
Oh dear, I would love to see her set up shop in the 99 precinct and smack Gina around some.
Ashi vs. Harley!
