Mecha Naruto wrote: There were lot of instances where the Hokages said their chakra was low, it could be that Orochimaru's Edo Tensei was imperfect compared to Kabuto's, I think that is the case. It's more likely that the Tensei do need time to recharge their chakra, but it's a much faster process than naturally regenerating.
