The Legend of Korra Season 4 Spoilers: Kuvira is the New Villain of Book 4, and Toph to Help the Successor of Aang?

The Legend of Korra Season 4 is getting interesting with each episode as the fan favourite Avatar will soon return to her city after receiving treatment in the Southern Water Tribe.

In the second episode the successor of Aang was seen recovering completely from the wounds she received during her fight with Zaheer in Book 3.

Though cured from her physical injuries, Korra is still struggling to overcome her inner demons as she keeps getting nightmares of her furious fight with Red Lotus' Zaheer.

With help from Katara she keeps getting better but does not know that something dangerous is waiting for her at home.

According to iDigital Times, Kuvira will be the next dreaded villain in Book 4 of the super hit animation series from Nickelodeon.

The final season of the spin-off of Avatar: The Last Airbender, will feature the former Zafou guard turned bad and perhaps this will be the final challenge for the brave Avatar who became wheelchair bound after the furious showdown with the Red Lotus gang in the season 3 finale.

Meanwhile, Toph has made an appearance in the second episode. He was last seen in 2008 as Korra's vision.

The blind friend of Avatar Aang greeted the mentally weak avatar fondly and said 'nice to see you again 'Twinkletoes''.

There are rumours that Toph may play a major role in helping Aang's successor regain her confidence.

Legend of Korra Season 4 episode 3 titled The Coronation will be available on Nick.com on 17 October.
