I was wondering about Shisui. First of all, he was a powerful Shinobi. He was considered a genius among the Uchiha. I was wondering who was stronger Itachi or Shisui. First of all Itachi could have caught him off guard. Thats what I always thought. I figured he either caught him off guard, or Itachi was just really powerful. Due to the recent fight between Itachi and Sasuke we see that Itachi is not invincible and not infinately powerful. Also when Itachi fought Shisui he did not have his MS. So I was thinking, could Itachi actually take Shisui on himself. I was wondering if since Madara helped Itachi slaughter the clan, did he also help Itachi kill Shisui. What do you guys think. Do you think Itachi killed him alone, or with help from Madara. Or do you think I'm totally over rating Shisui.
