Do you think Obito/Kakashi already used the full potential of Kamui? What do you imagine could be possible with it?
I thought about an "inverted kamui". Its does work like the normal kamui that teleports the body parts of the user that overlap with foreign objects in the real world into the kamui dimension. But this time it does it inverted. So it teleports everything in the normal world that overlaps with the body of the kamui user into the kamui world, and the difference is that it doesn't teleport the things back once they don't overlap anymore.
Imagine how powerful Obito would have been.
He could use his whole body like a lightsaber in star wars, "cutting" trough everything it touches. : D
