Why would animal path die? He can just chill in the chameleon and use the joint sight from the other paths to attack. And if things get tough he summons petra and that other one early. Then it's 4 against 1.
That's not how it went for Jiraiya. He never called others until Jiraiya started getting the upper hand, but since Itachi has quick moves that will kill him once they hit, he'll never call the others.
-Already said why Animal Path stands no chance, go read my post.
-Already said why the other 3 aren't going to come in at all while Animal Path is here.
This parts irrelevant as Animal Path won't be alive, but I'll reply anyway.
If itachi attempts tsukiyomi on konan Petra and animal path kill him during back lash. If he uses standard sharingan gen then they:
A) attack him directly which breaks the gen(according to chiyo)
Then Susanoo limbs crush them while Shurikenjutsu takes care of Preta.
Before or after Itachi kills them? Lol, before. Obviously, unless he stands there.
C) protect her when he tries to capitalize
He'll be right in front of her, they aren't fast enough to do anything, nor can they do anything with their moveset once it reaches this point.
Deva,machine, and the resurrection path were summoned all at once before jman put animal,petra and that other one under frog song.
Uh..wrong. They appeared AFTER Gama Rinsho.
Unlike hydra pain's dog isn't going down by cutting it. It would just multiply. Then you have the crab, bull, bird, panda, chameleon (and I'm STILL sforgetting some)to deal with all with linked eyesight. He's gonna have to stab them with totska which takes time to seal as seen by both nagato and oro monologues before death. Or ama which drains him. Not to mention the paths can see chakra buildup and possibly absorb it via Petra.
Not even gonna reply to this part. The way you have this fight laid out is pure nonsense.
-Since when was Animal Path able to summon all his summons before Itachi kills him, especially since Itachi can kill him before he ever summons them.
-Since when was it 4 on 1 when Itachi can quickly kill off Animal Path with 2/3 of his MS techniques?
Then konan who only got caught by gen jutsu when obito had to flat out choke a b¡tch and force her to look at him at point blank range. Not to mention her flurry of techniques and abilities. Mixing paper bombs with paper and such.
That is all Itachi has to do, don't mention her fodder techniques here. Ribcage says hi.
All that and deva and his crew didn't step on the scene yet.
The resurrection path brings animal(and all his summons) back, petra (to absorb itachi's fire balls) and that other one(extra line of sight I guess) back. To fight with machine path and his missiles/forehead laser, and deva with his gravity techs.
And at the end of the day he still has no counter to chibaku tensai.
The rest of this only comes about if we follow your ridiculous scenario
CT won't be used in his home village. Read the OP.
