'The Legend of Korra' Season 4 'Enemy at the Gates' Recap, Spoilers: Kuvira and Su's Standoff Continues in 'Battle of Zaofu'

In the last episode of Nickelodeon's hit animated series "Legend of Korra: Book 4," the titular heroine finally returns as herself after having conquered her inner demons and negating Zaheer's poison.

The celebration was short-lived, however, when Kuvira showed up with an army, along the walls of the metal-bending city of Zaofu.

Her demand is simple: surrender the city to the Earth Empire. Zaofu's founder, Suyin Beifong refuses and Korra has to come out to act as negotiator between the two.

The Avatar tried to convince Kuvira to leave the city in peace but was rejected. She came back to Zaofu and later found out that Su had plans on sneaking into the enemy's camp to do a surprise attack.

The imminent battle continues as the next episode titled "Battle of Zaofu" will air this Friday, Nov. 7, on Nick.com.

A recently-released sneak peek for the upcoming segment featured Suyin tagging along her twins to "take out" Kuvira before her plans of attacking the city starts. She believes that Kuvira's army has only been forced to participate in the occupation but once the head is gone, they too shall dissipate.

"Tonight," Suyin said, "we end her reign of terror."

The video then showed Su utilizing the signature BeiFong foot-vision technique to locate the dictator. She was found sleeping in a bunker with no guards around. They then set off to do the mission.

Will she succeed in her plans to eradicate the enemy? What will Korra do amidst the escalating crisis?
