am i the only one who is pretty sure this is a water bending move?
I’m a firm believer that the best benders are those who look beyond their own element’s bending techniques and discover new ways of bending. Look at Toph, she bends completely differently from other earthbenders, and she’s one of the most powerful benders in the world. Look at Iroh, he devised lightning redirection from waterbending. This just shows that Zuko is a great firebender.
I think it probably has more to do with the way Zuko changed from the beginning to the end of the story. Each bending art is modeled after a martial art that closely mimics the element. Perhaps Zuko’s change in bending style is supposed to represent how his once fiery spirit had become more tranquil like a water bender’s.
