Aang Mastered the Avatar State at the End of the Series.
I know reaction and movement are totally different things. But his was more of aim dodge like reaction/reflex than he reacted to it after it was fired. Thats my point hence Iroh being hypersonic reaction is likely not true, and also its massively inconsistent.
I guess Sokka is also supersonic in reaction because he reacted to Combustion man's flame?
THe OP changed it to being Avatar State Aang. Aang doesn't start out in base mode. Aang is going to just tear everything apart in landscape.
Avatar State Aang likes to fly most of the time though in full all out combat, doesn't mean AAng won't do what you said though.
OP also stated that he has Mastered it as well.
So Aang would not be tearing everything in the landscape, thats not how he behaves in the Avatar State with Morals ON at the End of the Series.
Movement Speed & Reation Speed are not important for this fight IMO.
So im gonna stop commenting on it.
Aang nor anyone from Naruto, has displayed the reactions to avoid Kamui.
@MisterShin: What is this "Aang will find Kakashi first" stuff? its not search and destroy, its a head to head fight. Just because it is a random encounter doesn't mean they have to locate each other before they can fight each otherI assumed by "Random Encounter" they would not be right beside each other.
If they are right beside each other, then it no longer a match. Its a clear Stomp everytime.
