Round 1 : Edo Madara vs alive old Kage
Minato and Muu are the only threats here.
Rasa is a seriously downgraded version of Gaara.
Gengetsu's Joki Boi won't pressure V2 Susano'o and his clam mirage genjutsu works by pumping out gas over a fixed area. AoE attacks will disrupt the gas and nail the clam, like any large scale Katon or Mokuton.
Ay the 3rd has great durability, stamina, speed and penetrating power. Won't matter when he's caught in a Genjutsu or when Madara's using the rinnegan to absorb his ninjutsu from close up.
Minato's FTG + chakra sharing is a bitch, as is Muu's invisibility. Muu could go invisible, aim to hit Madara and have Minato FTG him to a different angle to catch Madara off guard.
So through hax they have a minor chance. But a spam of any number of Mokuton Clones + V3 Susano'o and this'll be harder to pull off. They don't have Tsunade here to give them chakra for higher end moves either.
Round 2 : Edo Madara vs alive old Kage but Minato has kyubi chakra
Is this just KCM Minato or Bijuu Mode Minato? Either way, he swings this massively. Chakra sharingβwhich Kurama hailed Minato as quite adept atβreplenishes the other Kages and gives them some of the Kyuubi chakra. This has to purposes.
1. All their abilities are supercharged. From physical, to natural defensive barriers, to chakra attacks.
2. Minato teleported the entire alliance out of Juubito's barrier thanks to the shared kyuubi chakra. He now can recall any of the Kage from danger at a moment's notice.
The only downsides being that there's a 5 minute cap on Bijuu Mode, so after that everyone would be really vulnerable but still teleportable thanks to the lil bits of Kyuubi Chakra still in'em.
So it's a giant game of whack a mole. Madara uses Preta Path? Can't use Susano'o alongside of it, Rasa gets him.
Madara doesn't use Preta Path? Super charged Jinton from an impossible to predict Muu hits him. They seal him as he's reforming.
Mokuton in the battlefield can definitely be a deterant to soak up the Kyuubi Chakra, but god. Minato's so fast already and now he's able to teleport his allies to safety whenever? 6/10 in favor of them. Madara
always has a chance because Minato has his limits. But Bijuu Mode Minato is such a tough guy.
Round 3 : Edo Madara vs Edo old Kage
Same as above, except now stamina is less of a pronounced issue. So Edo Kage take it 7/10 times or possibly 8/10.
