Hatake Kakashi: Ultimate potential?
I've just been wondering a lot recently, with all the discussions that've resurfaced about Sharingan, and the Uchiha clan.
According to Uchiha Madara's account of the clan's history, Mangekyou Sharingan has always been obtained by way of killing their best friend, followed by the "Eternal" variant, occuring when binding the eyes of a brother, or such, with your own.
Recent data shows two Sharingan users that have developed the Mangekyou without resorting to these actions;
Uchiha Sasuke and Hatake Kakashi.
Sasuke, obtained his thanks to Itachi's interference. This then since developed into his own.
There's still a lot of mystery surrounding this.
Kakashi, however, seems to have unlocked his naturally. We know for certain that Uchiha Obito didn't have the Mangekyou Sharingan when it was implanted into Kakashi (it only had two tomoes, in fact). That said, we also know that Kakashi hasn't killed his best friend.
This thread isn't so much to theorise how Kakashi unlocked it, but more-so to ask if he can in the same way develop EMS on his own, without odd eye-stealing, and to question:
Is Kakashi's "natural" way of developing his eyes, the way it was always intended to happen?
Was the blood-stained past of the Uchiha clan just a consequence of misinterpretation?
Does Kakashi's way mean he has the opportunity to truly master this Doujutsu?
Or will he be hindered by the issue that he isn't of Uchiha blood?
Not so much a theory, more a topic of discussion.
