BK: When Tim Hedrick was hired as a writer on the original Avatar series, he was under the assumption for a while that when Aang went into the Avatar state he grew into a towering giant version of himself. The rest of us had a good laugh at his expense, but none of us would have thought back then that years later, that is pretty much what we would do with the next Avatar! I think Tim felt vindicated at long last. And I think he was right, as giant spirit Korra became a favorite Book Two design for me. I simplified her design and elongated her proportions to give her a more ethereal spiritual appearance. Designs and color by Bryan Konietzko.
