So I was suddenly reminded of that Blind!Zuko thing you’ve got going, and how you mentioned that alterations in ninja-ing would need to occur.
Thought #1: My brother, who is pretty much useless if you take off his glasses, took wrestling for a bit in jr high and high school, and they had him learn blind wrestling so his glasses wouldn’t get hopelessly smooshed. The gist of it was, never lose contact with your opponent.
Thought #2: I have a friend who taught me martial arts for bit, and also monologued about martial arts theory because that’s his thing. He also enjoys analyzing the theories and styles that are present in ATLA, but that is tangential. Basically, there are a couple of practices in Tai Chi (the style he knows is Yang Style, which happens to be one of the major influences for Northern Water Tribe bending) called Push Hands and Sticky Hands. I’ve personally only ever done Push Hands, but it’s an exercise where you make contact with your partner and practice sensing the momentum of the stance and their body purely through touch (it’s kind of similar visually to the way that Aang and Katara pass water whips back and forth). Sticky Hands is where you just. stick to them. My friend uses it in sparring a lot, because it makes it easier to react even when you can’t keep up with what the other person is doing. You just latch onto them, get up in their business.
I dunno, the implications of how Zuko’s could use a full-contact art with bending, which is usually relatively distanced, is fascinating to me. I’m definitely not a expert on these things, but I thought you might be able to add these to your list of things to research or poke at when the time came.
Ooo, good info. Gonna have to research those. <3
