I don't really care if Orochimaru was toying with KN4 and sick, even with double his power it's no tenough to beat Gyuki. Trust me Oro is like on my top 5 favorite characters but he can't beat KB. Bijuu dama still fodderizes him and he can use it more than once.
Yeah you can list a bunch of cool things about him but it won't change that he doesn't have an answer to either of those 2 things. None of that's an answer for a giant Bijuu Hachimaki and when Deva uses ST or BT then boom, bijuu dama or Gai helps.
He doesn't usually do that unless he's using Fushi Tensei, but yeah that'd be cool and all but Gai doesn't plan to stick around in 1 spot to breathe it or be affected and Hirudora, Hachimakis will just blow it away and it wouldn't affect them when they kill Oro in the process.
