And other than that we have some of the Character Bio’s with some Official Images

KORRA / AVATAR

Korra couldn’t have less in common with Aang, the previous Avatar. A 17-year-old girl from the Southern Water Tribe, she is as hot-headed and eager as she is talented. When she runs away to Republic City, her stubbornness and impatience get in the way of her bending studies, but it is clear from the start that she is destined for greatness. Korra discovers many new things in Republic City – some amazing and some terrifying. Whether its honing her bending skills in the Pro-bending Arena, facing off with street thugs or facing an anti-bending rebellion, Korra learns that being the Avatar comes with many dangers and responsibilities. As if being a teenager wasn’t hard enough on its own!

BOLIN / EARTHBENDER

No matter how intense things get around Republic City (and they do get intense), Bolin is always good for a laugh. Mako’s younger brother and Pro-bending teammate, Bolin tends to be more laidback and likes to have a good time. Despite their tough childhood, Bolin always has a smile on his face and a lady on his arm. In fact, it was Bolin who was responsible for introducing Mako to Korra. But Bolin is no clown. When the time comes to buckle down and bend some earth, this tough contender can handle his business.

MAKO / FIREBENDER

A Firebender with a serious side, the handsome and brooding Mako has always taken care of his little brother, Bolin. Growing up on the streets has given him a hard edge, but Mako loves his brother and will do anything to protect them both. Intensely focused on getting their team through the Pro-bending tournament and winning the jackpot, Mako’s tightly controlled world gets a little more chaotic when Korra enters the picture.

TENZIN / AIRBENDER

Tenzin and his wife Pema raise their two daughters, Jinora and Ikki, and son Meelo, on Air Temple Island. As Avatar Aang’s son and an Airbender, Tenzin carries a great responsibility on his shoulders to continue the dream of his father to protect not only the next Avatar, but also Republic City. Generally very serious and calm, Tenzin’s serene life on Air Temple Island is rocked when the impetuous Korra moves into his home to continue her airbending training. As Korra’s teacher, Tenzin finds his patience tested time and again but he also realizes that while she has a lot to learn from him, he also has something to learn from her.

CHIEF LIN BEIFONG

Her mother Toph taught Avatar Aang how to earthbend, but Chief Lin Beifong doesn’t feel any special affection for the new Avatar. In fact, this metal and earthbending police chief sees Korra’s arrival as the biggest threat Republic City has faced in recent times. Korra’s reckless ways are constantly leaving Lin Beifong’s streets in ruin, and this chief is determined to push bring the Avatar out of her city.

So there you have what we have gotten from the Korra Section of the Nick site, Keep an eye on this site for all the latest Korra news.

NAGA

Korra’s polar bear-dog is her loyal companion and main mode of transportation. Historically, this creature was feared and hunted by members of the Water Tribe.

PABU
