Once again:
- Konan had decades to figure out Obito's technique, decades of prep time. Hashirama's wont have it
- Hashirama is not as smart as Minato
- I suppose you meant Danzo's bodyguards? They figured out nothing. Being able to know how a technique works doesn't mean you can counter it and they countered nothing since Obito gave his arm himself
- No one really knew how exactly his Kamui works until Kakashi, so what makes you think Hashirama would figure it out?
@Bold and underline ....... just no.
1. Obito isn't gonna be able to see through the wood clones.
2. Hashirama can just wait around and what happens and how his ability works
3. If one of Hashirama's clone is on the other side..... then Obito is basically screwed, If Hashirama attacks him.
Fight is impossible, because Obito got the DNA through Madara, So if he is to go against Hashirama he literally can't have the DNA. But still, he has no where near the power that Madara had to have a chance against Hashirama.
Oh and lets not forget, BRINGER OF DARKNESS
