avatar is one of my all time favorite shows. now avatar especially in the avatar state is no joke. I think the problem that I believe the video adequately captured is that the avatar has at best maybe continent level feats while storm has planetary/cosmic feats. with benders they typically have to do movements with their bodies before the can cast their bending and their powers generally work on a local level. ororo doesn't have to be anywhere near you to send swarms of tornadoes down on you. I think the video did korra justice by nerfing storm in many ways to make it a fair fight.
the smirk storm did was one of my favorite parts. after being counted out and seemingly helpless she with less than a conscious thought sent a wave a lightning bolts atop korra setting the patth for ororos win. thank you cj for the commentary, even though predictable it was nice to see storm win this.
