Itachi vs Kakuzu




Kakuzu is pretty tough with his 5 lives. But no matter how many lives he has they are all subject to genjutsu. If Itachi looks at him he’s finished. Itachi could also just blow him up with Mangekyo Sharingan. Knock him out with Susannoo. Or Just take him down the old fashioned way with ninjutsu. Itachi wins.

Itachi vs Kisame




This is the first of my Akatsuki battles. Itachi would definately beat Kisame. First of all Kisame works for Itachi which already implies that he’s weaker. Also Itachi is stronger than Might Guy and Kakashi two ninja who may be able to defeat Kisame. Itachi’s sharingan would also take out Kisame in one hit. Itachi wins.

Itachi vs Aizen




In Bleach Aizen seems to be the strongest villain so far. However I doubt his illusion powers would work on Itachi because of Itachi’s sharingan. Illusions are Itachi’s specialty. I think he’d turn the tables and trap Aizen in a genjutsu. Itachi wins.

Updated. Aizen got a new super form and now his powers surpass that of Itachi’s. Aizen wins.
