He couldn't be the 10 Tail as an Edo Tensai maybe that's what he was talking about
na he didnt comeback stronger as a dead body is what i think it is
kabuto would know his true strength he wasn't around when he was fighting the 1st hokage
and oro edo seems better than kabuto this time around cuz the hokage came back way stronger closer too full strength
so with him being alive he can go full power with no restraints is what it seems but of course he could be killed now and run low on chakra but then again how often has that happen in this war
cuz I'm looking at naruto this dude went around the battlefields fighting edo dudes and zetsu then tail beast then obitio then sage of path obitio and now madara and he still alive
sasuke bout too fight him since they both very similar for the love of their brothers and how they lost them but what makes no sense is how can he if he aint nowhere near as strong as naruto is what I'm trying too figure out guess gonna be a power up somewhere
