kind of a ridiculous match up. theres no way oro and jman could defeat all of them one after another. Not to mention that with 3 hours to heal + the time it takes to fight they are looking at being up for a long time and thier chakra running dangerously low by time they get to itachi and kisame....not to mention that wouldnt be an easy fight for oro and jman. they might be able to beat them if they were fresh (remember, oro and jman worked together for years, they would be a very effective team) but after fighting 4 S rank akatsuki members? Hell no. They would lose this for sure.
Anyway i'll break it down what it might be like if they were fresh foreach fight.
Sasori and deidara.... i think they would win against those two. Orochimaru is not easy to kill, and sasori and deidara would have a hard time hitting jman when he is in sage mode.
Kakazu and Hidan- It would be an interesting fight, personally i think they would win but hidans immortality might give them some trouble.
Itachi and Kisame: I'm not sure about this one. I know that Itachi > orochimara A lot of people dont want to admit that but its true. I'm a much bigger fan of oro than i am of itachi, but i'll still acknowledge that he is stronger. so that leaves whether jman can make up for that, which i doubt. I'd give this one to itachi and kisame, with high difficulty.
Konan and Nagato- Well we saw nagato beat jman, but the difference in this fight is he has orochimaru on his side which would make dealing with 6 pains a bit more manageable. But Nagato also has Konan, who we havent seen he huge amount of but she's still a worthy adversary. I think that oro and jman could both solo her though. Since they know about the six paths i think they actually have a decent chance of winning. I cant say for sure though so I'll call it a draw.
100 white zetsus and tobi-Okay the white zetsus are pretty weak and oro and jman could straight own them, but if tobi is there too i dont think they could. Tobi and zetsus win.
The scenario you made was kind of stupid TBH. I dont think any team of ninja could beat every akatsuki member in a single day, maybe, MAYBE if it was some ridiculous dream team like Madara, hashirama and hiruzen (all in their primes) but even they would probably have some difficulity. Everyone in akatsuki is a S ranking missing nin. Oro and jman are both very strong, but they are literally up against an organization made up of a bunch of OP ninjas who are really hard to kill.
