The first official trailer for The Legend of Korra - Book Four: Balance hit the web today, and (not surprisingly) it looks freakin' awesome! Check out the video below for a sneak peek at what's to come:

Set three years after the events of Book Three (!), Korra's final chapter will no doubt be packed with surprises, including the return of a prominent Avatar: The Last Airbender character! Also ---- it looks like Captain Kuvira (introduced in Book Three and voiced by Zelda Williams) will be one of, if not the big bad in the upcoming season. (However, actor Daniel Dae Kim has confirmed that his character Hiroshi Sato will be back as well.)

Korra: Book Four will premiere on Nick.com and the Nick app starting next week on Friday, October 3.
