k, lets now say kabuto can not use Edo
havent seen kabuto fight in his newest form yet.
But with original battles, Kabuto demolishes Tobi in both cases.
Madara handles the nine tails
Third Raikage handles the eight tails
Itachi handles the seven tails
Kisame the six tails
the rest of the edos finishes all the other tails and keeps Tobi at bay.
Kabuto wins within twenty minutes.
