The Legend of Korra Season 4 returns this Friday with episode 6 'Battle At Zaofu' focusing on the showdown between Suyin and Kuvira.

In the previous episode, Kuvira brought an entire army in order to conquer the metalbending city of Zaofu but Suyin BeiFong will do everything she can to prevent the former from taking her city.

In the newly released sneak peek of episode 6, Su was seen using her twin sons to assassinate Kuvira while she is sleeping in her unprotected bunker.

"Tonight we end her reign of terror," Suyin tells her sons as the three earth/metal benders plan to kill her.

The Legend of Korra Book 4 Balance, episode 6 will start streaming on Friday, 7 November on Nick.com.

Meanwhile, show creators Bryan Konietzko and Mike DiMartino have clarified on why they wanted to have a female villain to fight against Korra, the Avatar in Book 4 'Balance'.

"When we were coming up with Book 4's antagonist, we wanted her to be female," DiMartino told Hypable.

"And for Korra to have to face someone with some similar personality traits."

Taking on the would-be leader of the Earth Empire, he admitted, will be "like Korra has to deal with overcoming a version of her past self," he added.

The show creator also teased that the successor of Aang will have to be more powerful to fight with the villain of the final season.

"Korra's struggle with Kuvira will not be easy. I would say she's a pretty big threat. And I don't like what she has in plan for those spirit vines, just saying."
