Gravity Falls Sharingan Chapter 3 or Editorial

Okay I've read the reviews and I'll explain the Sharingan for people who don't know. In fact I'll do these editorials for anyone who doesn't know anything about Naruto or Gravity Falls. Anyways the Sharingan is the Uchiha bloodline. It's activated through the despair of one person. Its ability is that it can copy the tiniest detail of every movement. It can also cast genjutsu and grows more powerful with every comma it gets. Once it has 3 it has fully matured however it can grow even more powerful if you kill your best friend. These eyes are called the Mangekyo Sharingan. The eyes change into very interesting shape like a star or a shuriken. Abilities: Amaterasu or the eternal black flame, Tsukuyomi the 3 day genjutsu that causes pain, Susanno the chakra of the uchiha's that take the form of a warrior, and so forth. In fact some eyes can give the user very interesting abilities. However the problem is that it give the person eternal darkness or blindness this is crippling since people need their sight. The only way to get the Mangekyo and keep your sight is for you or your siblings to give up their eyes for you. After that you've got the eternal Mangekyo Sharingan. And that's about it except if you want to learn more read the Naruto wiki.
