@UltimaDude When Orochimaru revived Hashirama and Tobirama the first time, he didn't revive the former Hokage at their full power. The second time around, Orochimaru revived them at near their full power, which required the Sannin to use Hashirama's cells to strengthen his control on Tobirama, while Orochimaru couldn't control Hashirama at all, because the First Hokage is that powerful.

Also, just advice, you don't have to drop f-bombs when you want to ask a question to somebody else. How do you expect the answer to be when you do that? Just saying. Carry on.
