Danzo has sharingan...

[AizawaHiroshi13]

anyone else think thats weird? or think danzo doesnt deserve it?

Once I found out that Danzou had Sharingan, I was soooo pissed. The guy's a douchebag, and doesn't deserve the Sharingan...

Then again, there's a little theory going around stating that Danzou is actually Tobi... 0_o I think that he might have gotten hold of someone else's Sharingan...

If that were true that would really cause some trouble to those who think he doesn't deserve it. For me I don't think he is Tobi at all cause Tobi is energetic and funny but Danzou or whatever his name is doesn't at all deserve to have the sharigan.

As it turns out Danzo isn't an Uchiha and he isn't Tobi the guy got the Sharingan and parts of the body of Shisui Uchiha grafted onto his own. That was Itachi's best friend the one he he killed to get his Mangekyou Sharingan. That is how he got it. You want proof here you go.
