while looking at everything orochimaru is doing i nooticed something
Orochimaru wants sasukes body... we all understand that much.. but why??
to have all his abilities and knowledge with the limitless potential of a uchiha body,,
understand also orochimaru had plans to get sasuke way before he seen him at the chunin exams, he ambushed the kazekage with his anbu guards and killed everyone. that takes time
and also when sasuke is training with orochimaru oro thinks to himself "and they thought i was a genius" like he was suprised that sasuke had progressed so far. so we can come to the conclusion that regardless of skill level he just wanted the body any uchiha. and the fact that sasuke was progressing so far was a plus
Yamato was the only one of many thats survived oros experiments to clone the 1st hokages dna. until the bridge when naruto whent crazy oro didnt know about yamato, and nobody wanted him to know about yamtao for obvious reason he was trying to make yamato for a reason and they dont wanna know why..
now what does all that equal??? Exactly what hes been telling everyone.. he wants to understand all the jutsu in the world and the only way to do that is to get rinnegens and become like the creator of all jutsu.. maybe this was obvious maybe it wasnt but i wanted to point it out
