prime Tobirama and Danzou vs Hydra Oro and Byakugou Tsunade

[Totsuka gg Amaterasu gg]

hydra oro losing to itachi doesnt mean shit here. danzo would be outlasted by orochimarus immortality and snakes in the NO KA fight. with KA danzo solos. tobiramas worthless. \
add onto that the fact ET isnt restricted.
orochimaru summons minato hiruzen hashirama. then sits back and drinks tea

why would Tobirama fight his own subordinate?

I don't think the edo hokages will help Oro

Thunder God Slash doesn't bisect people last time i checked...
If it comes to it Oro could simply use ET, summon Hashi and let him do the job. He wouldn't even need to go all out to defeat Tobirama (without killing him) and kill Danzo.

i dont think they have any choice in the matter. they fought hiruzen
