Obito wins lol, i must say that easily OR maybe, only MAYBE with mid difficulty, well, Kakashi would be pretty fodder without his Sharingan imo, because he would have never perfected Chidori nor would he have copied over 1000 techniques
Oh whatever, obito would lose. Kakashi doesn't need a sharingan to beat obito. And naruto is beyond OP with BM. Let's see, he can have what, three clones with BM, and each would fight him. Then kakashi would be there fighting, using whatever he has. All he needs is lightning blade. Obito would lose. High difficulty, but still a loss.
Obito no diff he already took them on plus 2 other characters taking away there only advantage is just sad they couldnt even hit him withought that eye lol now he could warp from distances without the strain that Kakashi has and they cant escape
The only time Kakashi injured Obito was with Kamui, take it away and Kakashi is meaningless.
Obito would also just use a long-range Kamui on Naruto. No fight if he's trapped in a different dimension.
