Just because he jumps through fire, doesn't mean he's bending または anything. あなた don't just catch on 火災, 火 if あなた run through it. あなた know how if あなた hold a candle wick against a flame, and it takes a few 秒 to light? Same thing with Amon. His clothes were probably designed not to catch 火災, 火 easily- he has to carry those electric things with him, right?- and he's agile enough to just jump through it quickly without getting burned.
Tarrlok 発言しました something around the lines that Noatak could have used subtle bloodbending to slow down his opponents, または 移動する their hands または movements so when they attacked him with an element, it would just briefly miss.
But in this case, all I can come up with his his agility. He moves very quickly and he is also very durable- the man was able to stand on his feet again after being electrocuted によって lightning, merely a few 分 later- but I don't think Mako's lightning is quite as powerful as a master's. ..When I saw the scene with Noatak and the fire, it almost looked like it moved out of the way for him- like he was in a bubble. Maybe his psychic abilities stretch beyond waterbending for all we know?
amon probably knew that he would get attacked によって a lot of the elemnts before he started the revoulotion so he probly he made armor that negated the effects of a lot of the elements plus he really agile and somebody try to tell me he doesnt look awsome
