All except the following:
Definitely cant take:
SO6P (Dont need to explain)
Hashirama (Controlled 7 beasts, everyone wants his cells. Beat the baddest man we've seen so far. Enough said)
Hiruzen (God of Shinobi, enough said)
Tobi (Dont need to explain)
Kabutomaru (He'll just summon some beast edo's. End of fight)
Could take:
Madara (alive Madara, not Edo)
Nagato
Jiraiya
