Sharingan Tobi and Zetsu Vs Rest of Akatsuki without Pain and Itachi

[Uzumaki16]

Location-Open field

Starting Distance-10 metres.

Knowledge-Tobi and Zetsu have full knowledge while Akatsuki has none.

Mindset-Kill

[Simple Math]

they got no answer on s/t so the duo win.

[EjBlack]

Deidara does. Edit: NEVER MIND OP said no knowledge. But by observation during the battlefield they can do it.

Akasuki low-mid diff.

akatsuki

[USSJ Future Trunks]

given that they have no real counter to obitos s/t they have to let him come to them. theres a chance he will have to breath sometime in which case poison gas and C4 are the answer. but zetsus a sensor and obitos got MS so its exceedingly difficult. zetsus almost no use to obito though besides spamming clones. if obito has kyuubi its a massacre

[hatake axel]

Zetsu would be wiped in no time.

After that I think the akatsuki can keep attackin Tobi
until someone hits him.

With:

100 poison pupets
and 6 katsuki members that are
Sasori
Deidara
Kisame
Kakuzu
Hidan
Konan

One drop of blood the anyone gets from Tobi and
Hidan would finish him.

I couldnt have put I better myself

Well, if they'd be able to constantly attack Obito while evading his attacks for 5 minutes I think they could possibly beat them. Zetsu is no problem for them.
However, It'd be extremely difficult, and I'd give this fight to the duo 8 out of 10 times

[GreatestUchiha15]

All it takes is Kakuzu,Kisame and Konan

kuchiyose: nine tails

kuchiyose: nine tails

You are forgetting the nine-tails is sealed within Naruto and cannot be summoned by Obito.

Obito can trap Hidan and Konan in the Uchiha Batte. Encampment. Neither have the fire power required to escape.

Kisame's Water techniques are useless since he'll just phase through them. All he needs to do his get close and touch him then its over, or get close and fire those shuriken from his eyes. To prevent interference from the other member while he takes them all out one by one, he can have Black Zetsu hold them off(he could fight a Mizukage, several jonins and KM Naruto)

He can simple sink underground and re-emerge behind Sasori then unleash a wave of large shuriken to stab through him or use his fire techniques.

Deidara's attacks are known to him so he can evade them, get close and shuriken or warp Deidara. If Deidara uses C4 or CO he'll just go intangible and let Deidara kill everyone

Kakuzu's ability to act through many hearts and increase his body size with his long range mode will pose quite a problem since once Obito goes tangible to warp him, the hearts will attack with massive long range techniques and Kakuzu's body is quite large in long range mode so it'll take a longer period of time to warp him, however, if he can trap some of the jhearts in the Uchiha Battle Encampment(a barrier that could withstand the full power of a Tailed Beast punch with no damage) and warp some away with Kamui leaving just good ol' Kakuzu, enough shuriken in the back, using his weaker level of Mokuton to capture and suppress his chakra and Kakuzu's done.

Orochimaru is a VErY big problem. He can vomit himself to prevent being KAmui'd then take advantage and attack Obito while he's solid by stabbing with Kusanagi or using a Five Element Seal to inhibit his chakra or render him unconscious. Even sneaking up behind him to use shuriken to tear him apart is useless since he's immortal. Obito's best chance is genjutsu or using his weaker form of Mokuton to capture Orochimaru and suppress his chakra. Considering the massive Mokuton Obito could accomplish as a kid, it won't be impossible for him.
