|Taf joined Boline and the others on their mission to save Kuvira's prisoners, and with her help they made it out no problem. Boline also rescued Verrik's assistant, Juli... she reports that Kuvira plans to attack Republic City within a few weeks. Korra's trying to get the spirits to help fight against Kuvira, but they refuse to get involved in human conflicts..|
Kuvira starts her attack on Republic City earlier than anyone expected.. and she even has a giant mecha suit attached to her spirit vine super weapon. The president has no choice but to surrender, and Korra's team are the only ones not giving up... they capture Kuvira's boyfriend (who is also the son of Su Beifong), and tried to force him to make Kuvira stand down... but then Kuvira attacked them all including her boyfriend.
Korra and the airbenders/earthbenders try to hold Kuvira off, while Asami, her dad, and Verrik and Juli try to come up with a weapon that can defeat that mech. Meanwhile, Prince Wu manages to get all the civilians to safety, and proves that he does have the leadership qualities of a king after all..
Verrik proposes to Juli during all of this, in the most ridiculous way possible..
"Juli, will you "do the thing" with me for the rest of my life?"
These 2 are actually really funny, they're way better comic relief characters than Boline.
They manage to get inside Kuvira's mech and blow it up. Korra fights one on one against Kuvira, and Kuvira takes the detached super weapon and fires it, but then the spirit vines grab the weapon and make it explode. Korra goes into her avatar state and shields Kuvira from the explosion, which causes a new spirit portal to open inside Republic City... Korra manages to reason with Kuvira and get her to turn herself in... The series ends with a wedding party for Verrik and Juli, and then Asami and Korra go on a vacation into the spirit world.
