Just a thought, but i wonder why Kabuto didnt revive his old master Oro.
He had alot of knowledge and Kabuto could have controlled Oro fully so Oro could have teached him everything he knew without any limits and help him to gain even more knowledge. Maybe he did and thats how he improved IWR?
If not, why did he not? Only half of Oros soul got trapped into the 3rds sealing tech, so one half would be available... and Kabuto shall have alot of Oro DNA in his arse... arsenal i mean
