Its teleportation isn't it?
Flash is faster than instant my friend, your words are flawed there...but here its confusing so I'll tell you why.
All those things are instant Obito, FTG, Sasuke's tele
Obito was faster than light with only one, Minato self explanatory, Sasuke solo'd Madara a juubi jin close to Kaguya
Did you forget guy who distorted space wasn't fast enough.
Minato got solo'd because of his reaction time isn't where FTG is and so did Obito....as we've seen Sasuke's surpass both of them in reaction time therefore its more useful.
There is no "instant", kid. What you call "instant" is supposed to be the unmeasurable smallest amount of time possible. There shouldn't be anything faster, because it's supposed to be the smallest amount of time.
Yeah, it's a teleport, and I understand it's mechanics. It consists in folding space-time in a ridiculously small amount of time so that the person can reach another place in the universe in that time.
It's time is indeed extremely small. But we don't have anything to say that it's the smallest amount of time possible.
You people just assume it's "instant".
As I said, by definition, nothing is faster than instant. There is no such thing as "more instant" either. Since you mentioned flash, you might as well mention superman, who surpassed a teleporter. He wasn't faster than instant, he was simply faster than the time of the teleport I mentioned.
In NV, that matters not, to be honest. But the "instant" crap gotta stop. Kamui had it's speed doubled a few chapters ago, which obviously means that it was never instant(definition).
Just as I said, there is no such thing as instant. FTG, kamui, sasuke's power, they're all teleports. And indeed, in NV, that amount of time seems to be the same, and is indeed unmeasurable, unnoticeble by anyone. Still, it's not as instant as you people "instantly" claim.
It's simply the way you use the "instant" that bothers me.
