It's ok... But black zestu they say was before white zestu and zestu couldn't use wood style till kabuto gave it to them it also wouldn't make sense tht Tobi has no hashirama abilities and couldn't b madara cuz madara has EMS/rinnegan we haven't even seen Tobi MS (at least I haven't) (thought he just had the three black things) and tbh madara never wanted to learn anything and it didn't say on his bio he has tht creation jutsu he doesn't seem OD smart/nerdy or trying to find secrets of the world type like oro and kabuto he seems like an arrogant jerk (sasuke) to me and not tht smart battle smart yes but not all brainy smart no..
Where does it say that Black Zetsu was alive before White Zetsu? I don't remember that at all, and I personally think you are pulling that out of your ass. Also where does it say that Zetsu didn't have Mokuton until Kabuto used Yamato to power them up? The only thing Kabuto did was make them stronger, he didn't GIVE them Mokuton, they already were made of Mokuton. That's why Kabuto was able to make them stronger with Yamato, because they ALREADY HAD Mokuton.
Only thing I kind of agree on is that Madara probably didn't have Creation of All Things. Just because he had the Rinnegan doesn't mean that he could use Creation of All Things, I think only the Sage of the Six Paths could use that Jutsu.
Madara never had rinnigan he received it as an edo just like the jinchurriki have shiringans llike tobi, or danzo with an arm of eyes.
Edo brings back a person in their prime, most died in their prime. Hashirama and his wife were both elderly when kushina became the new host for kurama
Madara himself stated that he awoke the Rinnegan shortly before his death. So I don't know where you are getting that he didn't have Rinnegan until he was an Edo. He had it when he was alive, and gave it to Nagato shortly before his death. How else would Madara give Nagato the Rinnegan if he didn't have it until recently? Plus how the **** would Kabuto be able to give Edo Madara the Rinnegan? Like Kabuto just has Rinnegan's lying around.
And who said Hashi was elderly when Kushina became the host? The only person we see if Mito when Kushina was a kid becoming the host, and yes Mito was elderly. It does NOT anywhere show Hashirama during that time period. Most likely because he is not alive, since that was to recent.
