I've been comparing Zaheer to a tornado: Fierce, stubborn, aggressive, paradoxical, wreaker of havoc. But after watching this fight, I've come to realize that while Zaheer is a tornado, Tenzin is a supercell: Beautifully structured*, organized, graceful, looming, terrifying, and overall much more powerful than any tornado. It's for more than one reason that they call it the parent storm.Also, I've been calling Tenzin the cumulonimbus of the Cloudbabies for a while (of the three, he's certainly the stormiest, as well as the tallest). Guess he just now achieved supercell status.*I mean that in terms of airbending skill, although I will say that it's quite easy to see why Pema gave him four kids.
