Sorry if this has been discussed but i am still lost abt this jutsu. usually most of the shinobis ressurected by kabuto look like how they were when they died. but madara, if anyone remembers he took in obito and trained him etc. he was old then and he died that way. but He was bought back to life younger by kabuto. Much Much younger. So how does edo work? u can pick the age of who u want to resurrect?
