He might be able to, I mean if he can teleport himself into the dimension then he can teleport himself out, although I doubt he can control where he goes when he leaves the dimension, and I also doubt kakashi would use it like Obito since the kamui he has is for long range it would take alot of work/ chakra to teleport himself
In the first scan, we see Kakashi being sucked into the Kamui dimension by Obito.
In the second scan, Kakashi begins to warp himself while in the other dimension. We all originally believed that Kakashi's Kamui only had access to the alternate dimension, meaning that was the only place it could send a target to.
In the final scan, we are shown Kakashi reapearing on the battlefield from the alternate dimension, disproving the notion that his kamui only has access to the other dimension. Perhaps he is now capable of using Kamui as a means of travel like Obito does...
He has the same abilities as Obito's Sharingan, but on a weaker scale since he does not have Uchiha DNA. When push comes to shove, he can do the things Obito does I bet, but he'd pass out or die.
I got an theory, Kakashi's kamui sent him to the the regular dimension only because Kakashi was already in the alt dimension so if he kamui'd himself it would have to work, I mean come on? Why would BOTH of Obito's eyes have the same ability
Maybe they both have the same ability because it's the ultimate non genjutsu Sharingan technique.
Also Obito doesn't even use his MS for his Kamui(except this chapter) he can do it with just his Sharingan...I wonder why...
Maybe he has some freaky thing like Danzo on the go where he has multiple Sharingan in his body.
Anyway OT I think in time he could develop it to Obito's level but in this chapter it's a case of
Normal dimension Kamui = alternate dimension
Alternate dimension Kamui = normal dimension
So if he used it in the alt dimension to cut Deidara's arm off then his arm would land in the normal dimension.
the difference is Obito's is short range, while Kakashi's is long right?
Kakashi mentioned he is able to control the size of the barrier space, and Deidara said he felt like he was being sucked in, so i just assumed Kakashi made a big enough barrier space to absorb himself. Right?
Anyway, does this mean Kakashi could theoretically make himself intangible if he just looked at whatever body parts he needed to be? Sure, there are blindspots and he doesnt have the chakra to do so all the time like Obito, but theoretically.
Another difference is the control of precise parts sent to the other dimension. So far we've only seen Kakashi teleport his whole body back from the other dimension... but Obito can send only the overlapping parts of his body to the other dimension. This puts Obito's ability to exploit it defensively on a whole other level. Just because Kakashi can teleport back doesn't mean he can use it defensively yet, because if he can't teleport his body as precisely as Obito it's worthless defensively.
I think that their are plenty of meaningful differences which have already been pointed out between Kakashi and Obito's doujutsu that we can save with a good degree of certainty that they are not the same
