I updated and put numbers on the Sharingans so you can tell which is which
12/9/11 : Updated again! I added some more stuff to show everything. So maybe spoilers...
I love Naruto shows!
1:Uchiha clans normal eyes
4:Third Stage (After third, the sharingan form changes because its different for everyone.)
5:This is Itachi's eye when he destroyed the Uchiha clan but the picture is little different than the show, go to [link]
and around 16:02 youll find the eye that is similar
6:This one is Itachi's mangekyo sharingan
7:Kakashi's mangekyo, used during the fight with Dedara(Two hand mouth).
8:This is Sasuke's mangekyo sharingan
9:This is the one that Madara's brother Izuna used.
10:This is Madara's mangekyo sharingan
11:Madara's final mangekyo sharingan
12:This sharingan was used by Shisui Uchiha
13:Sasuke's eternal sharingan formed with his eyes and Itachi's eyes
14:I just threw this one put because apparently sharingan came from rinnegan
Well if there is more I will put more, but for now this is all they show in the further episodes. Go to Mangastream.com, Mangahere.com, animefreak.tv, or animeseason.com to read or watch.
