I've searched the forums and have either missed the thread that had this or i am right in assuming that this would be a first. if it is the former, then my sincerest apologies. if it is the latter, then good for me
With regards to the topic that i stated, i just realized that konan said that tobi has to materialize before he can go to another dimension which is how konan managed to harm Tobi. if that were the case, would it not be possible that a well timed kamui might be able to tear tobi in half since we don't see any of kakashi's warped items in the same dimension as Tobi's (BTW: I say tobi since i am not assuming him as Madara)
please give me your input on this as I'm still unsure whether this is truly possible.
