'The Legend of Korra' Season 4 Spoilers, Preview: Off to a Good Start; Fans Brace for a Possible Korra vs Kuvira Match

"The Legend of Korra" Episode 4 of Season 4 titled "The Calling" promises to be another gripping instalment in the ongoing adventures of the "Avatar Korra."

This time, her powers and intent are totally set on crushing Kuvira (voice-acted by Zelda Williams), the newest addition to the line-up of villains.

The episode, also known as Book 4 and titled "Balance," is scheduled to be shown online on Friday, Oct. 24, 2014.

As has been the case since Season 3's Episode 9, "The Legend of Korra" shows its new episodes online first, rather than being broadcast.

This season will reportedly be the last. As such, it's expected that major issues brought about in the first three episodes of Season 4 will be resolved with the Avatar Korra's journey of self-discovery being accomplished, together with settling the unrest caused by Kuvira in the Earth Kingdom.

As it currently stands, Season 4 has tackled Metal Bender Kuvira's displeasure with the coronation of the new king of the Earth Kingdom E 3, highlighting the evil intent of Kuvira.

Korra's search for her avatar in the physical plane and the spirit world was featured in Episode 2. This was an interesting follow-up to the expressed hope of the people of Republic City to see Korra again (Episode 1). Unfortunately, their prayers were not answered.

Now, with Episode 4, will Korra finally meet Kuvira in a head-on battle? Will Kuvira be a stronger, harder-to-defeat enemy than Zaheer? Or will Korra's difficulties with her inner self prove to be the toughest enemy of all?

Find out the answers when Season 4, Episode 4 of "The Legend of Korra" bursts online on Friday.
