Avatar: The Last Airbender / The Legend of Korra - Empress Kuvira.

So this is how liberty dies

With thunderous applause

So if that's right…
Bolin will kill Kuvira
Kuvira is building a giant space station meant to destroy the world
Bolin will be revaled to be Korra's true dad
Bolin will kill either Mako or Tenzin (I think Tenzin fits more as Obi-Wan)
And, most importantly:
Giant metal camels. (AT-ATs)

Though I think we can agree that giant metal camels, star wars reference or not, would be pretty fuckin cool.
