What if Kuvira is the next Avatar....or is going to be related with him/her ? Seriously,just think about it! In the last episode of " Legend of Korra" when Korra saved Kuvira from the spirit vine energy and created a new portal to the Spirit world, she saw Kuvira as her reflection the way she used to see her past lives!Even more interesting is that Korra was BLUE (like her past lives) and Kuvira was PURPLE(like a current Avatar). I know this sounds maybe a little bit strange,but think about it.Perhaps there is a reason for Korra to say that she sees a lot of herself in Kuvira.... I don't know, this is still my fictional explaination and it kinda makes sense.I find it as a good life mission for Kuvira to redeem herself for everything she has done by being or training the next Avatar.(I know that the next Avatar is supposed to be a reincarnation of Korra,but things could change,right...
