Ive just presented visual proof. so i migh aswell post the article then, since you seem set that he isnt.
This may contain spoilers for anime only fans.
Spoiler:
developed his own version of the Mangekyo Sharingan during the timeskip. Unlike Itachi's version, which is used to destroy a target, Kakashi uses his to create a localized interdimensional space-time warp, allowing him to target any object and send it to another dimension, achieving the same result. Kakashi used this new jutsu to warp a segment of Deidara's right arm into a different dimension. He immediately aimed at Deidara's head for a second attack, but missed. He subsequently uses it again in Chapter 278 to counter Deidara's ultimate move, which would otherwise level the entire forest they were fighting in. The attack requires considerable effort to aim precisely and appears to leave Kakashi's chakra significantly drained; he collapses after using the technique three times in a single day (compared to his other original move, Lightning Blade, which he can use four times a day)
Spoiler:
The appearance of the pupil and tomoe in Kakashi's Mangekyo Sharingan differ from that of Itachi's; Kakashi's looks more like a pinwheel. Before this was shown, it was thought that one had to kill their best friend to acquire the Mangekyo Sharingan. This clearly isn't the case with Kakashi, who stated long before developing his Mangekyo Sharingan that everyone close to him was already dead. The only known now-deceased person that could be described as his "closest friend" was Obito, who died shortly after giving Kakashi his Sharingan eye. While Kakashi may have felt responsible for Obito's death at the time, he certainly didn't kill Obito himself, and it wouldn't explain why it took him so many years to obtain the Mangekyo Sharingan. Thus, the means behind its development and the actual meaning of the "requirement" are currently unknown.
Had to split it up for some reason =/
