You cant get a dead body in a genjutsu that effects the brain because there brain dead all itachis genjutsus works through the brain because he talks in there subconcious in there mind as shown with naruto,sasuke please respond to this pleaseu did not follow my explanation i said that when tendo is in genjutsu, when he was in konoha he was not going all out he used a lot more techs in his fight against sasuke and he was sick and going blind. paths are slower than itachi most of them barely dodged a rasenshuriken and itachi dodged bee's 7 swords attack in recent manga, he also was fast against sasuke vs itachi fight
