I'm not sure why Hashirama can break out of Edo Tensei, whether it's because Oro is using his cells to strengthen the restraint and because it's Hashi's cells, it has no effect on him and his power is enough to break out of Edo Tensei (like Tobirama), or is it because he's just the God of Shinobi and his power > Oro's restraint (even with Senju DNA)?
