I do apologize if this thread has been made before, but lets say a person summons an edo that has complete control over their body. Could that edo learn new jutsu, or is it limited to only the jutsu they knew when they died?
As we all know by now, Madara broke free from the Edo Tensei. This got me thinking on how he knew the signs. Seeing as how Tobirama created the technique, it made me come to the conclusion that he used it to bring back Izuna. It was possibly done to help the alliance between the Senju and Uchiha...
