This Leopards damaged eye

That's fucked up 100% but at least it looks cool.

That is a Shinnegan. A kekeigenkai if you will. It's not damaged, just let's him see the blod vessels in his pray. Uses a lot of chakra though

It kinda looks like a wolf howling with a moon and a forest burning in the background.
Ow but wow.

Has anyone read the book “Zoo” by James Patterson? Creepy!!
