Can anyone please explain the part about Oro not being able to use his arms? I know that Sarutobi sealed them, thus stealing all of Oro's jutsus. But we most certainly saw him using jutsu after his Fight against Sarutobi: http://www.mangareader.net/93-300-8/...apter-295.html. He seemed confident that there is a way for him to revive them (http://www.mangareader.net/93-176-4/...apter-171.html).
We know that he took over another body before the time skip. I assumed that this way, he could use his jutsu again. Yet now that I think about it, he did not use any seals during the fight against Four-Tails-Naruto.
If that's true and he can't use seals any more, then why is he considered dangerous. Itachi was stronger than him about 3 years ago, and without any seals. Naruto and Bee are most certainly faster, and Sasuke - given he is as strong as his brother - should be able to handle him, too.
What do I miss?
