Kakashi looks up toward the headband covering his eye and removes his anbu mask.
"Okay. The Sharingan is the sole bloodline trait of the Uchiha clan. Some people, such as me and Danzo Shimura have obtained the Sharingan in different ways. I got mine from my team member Obito, Danzo got his from Uchiha clan members. The powers of the sharingan vary on it's many different stages.
1 Tomoe grants higher perception and you can track higher speeds than your own. Precisely a single rank above my own at the time of using.
2 Tomoe grant higher perception and the user can also copy techniques the opponent has used so long as they have the proper training for it. It also can allow you to mimic subtle movements such as a pen or pencil on paper.
Finally 3 Tomoe grants the user higher perception, copying capabilities and the ability to hypnotize the enemy by forcing them to unconciously use the same technique you are, which creates a mirror effect. While in reality you are simple copying their hand signs and making them see you use them slightly before them. Giving the illusion that you can read their minds.
Mangekyō and Eternal Mangekyō Sharingan are both very advanced techniques that have been awakened by very few Uchiha.
It should also be noted that even though one can see higher speeds doesn't mean they can react fast enough to block the attack."
Kakashi stands up and dusts himself off.
