Kabuto's snakes go towards Y/n, Sasuke and Itachi as they instead slam right into the ground so they all fall down to a lower part of the cave. Sasuke and Itachi are able to hold off the snakes with their Susanoo while Y/n uses purple lightning to slash at them

Sasuke: We will just have to find a way to get close to him!

Itachi uses his Susanoo arm to pull Kabuto towards them while Sasuke goes in to take off his hood..but there was only snakes under the hood

Sasuke: What? How was he able to escape

Y/n: Watch out. There is chakra everywhere, he is plotting something.

Kabuto: I was able to find the place...!! A place as legendary as Mt. Myoboku and the Shikkotsu Woods!

Y/n: You mean you found Ryuchi Cave?

Kabuto laughs

Kabuto: I have finally been able to do something Lord Orochimaru wasn't able to do, and that's master sage mode!

Sasuke: I've had enough

Sasuke goes into his humanoid Susanoo form as he fires on of his arrows towards Kabuto but Kabuto just dodges it

Kabuto: My senses are even sharper now...I am in my natural element

Kabuto puts his hands together as he breathes in

Kabuto: Sage Art: White Extreme Attack

A large dragon shoots towards Y/n, Itachi and Sasuke as the dragon creates a screeching noise causing them all to close their ears

Kabuto: I am the only one who can move in this situation!!

Kabuto rushes towards the most vulnerable one which is Y/n as he goes in for an attack on Y/n but Y/n senses Kabuto and gets his sword ready

Y/n: Purple Lightning

Y/n counters Kabuto's attack by slicing a bit of his horn off causing Kabuto to smile

Kabuto: I never knew you could sense my chakra Y/n...

Y/n: I have my ways.

Sasuke uses his chidori spear as he goes in for an attack on Kabuto but Kabuto goes up onto the ceiling

Itachi: Sasuke...remember that time I dragged you into that mission I was doing

Sasuke: You mean the wild boar?

Itachi nods as he looks ahead

Itachi: Let's do it.

They both go into their humanoid Susanoo mode as Sasuke gets ready to fire his arrow. Itachi goes in close and uses his beads and throws them straight at Kabuto

Sasuke: Now!

Sasuke flings his arrow at Kabuto as it hits him right in his snake tail causing Kabuto to dangle. Itachi then takes Sasuke's sword and runs towards Kabuto but gets stabbed by Kabuto

Itachi: You have fallen into my trap

Itachi uses his genjutsu as he turns into crows and goes on the offence and slashes another one of Kabuto's horns

Y/n: I must say....you two are quite the duo.

Sasuke: So what are we going to do about this snake

Itachi: He doesn't know the true power of the Uchiha. We have a visual jutsu that can be used on a opponent without eyesight

Sasuke: Izanagi...?

Itachi: I'm not talking about izanagi, I'm talking about it's over half.

Itachi runs towards Kabuto and blocks his attack

Itachi: The one called Izanami. That is the one that can define a person's fate.

Kabuto puts his hand together

Kabuto: It seems that you guys are still underestimating me

Kabuto: Sage Art: Inorganic Animation!

The points in the cave go towards Itachi as they are able to trap him

Kabuto: I guess now I should rewrite your mind

Kabuto runs towards Sasuke, Y/n and Itachi to try and put the kunai in his head but Y/n slashes at Kabuto causing him to jump back

Y/n: Sorry but I can't let you do that

Itachi: Thanks for the sage...Y/n Uzumaki

Y/n: No problem

Sasuke: When is this Izanami going to be ready Itachi! He is coming after us!

Itachi: I'm already onto him, but it will take some time

Kabuto's body somehow morphs into that of Jirobo as he weaves hand signs

Kabuto: Jirobo! Earth Style: Terra Shield!

Jirobo puts his hands onto the ground as it creates a massive shield. Suddenly Kidomaru is in Kabuto's body as well

Kabuto: Kidomaru! Sticky web!

He creates a web and throws it at Sasuke, Itachi and Y/n

Sasuke & Itachi: Amaterasu!

They both use Amaterasu and burn the web

Kabuto: Kimimaro: Macabre Bone Pulse! Bracken Dance!

The bones come towards Y/n, Sasuke and Itachi as they all get ready

Y/n: Wind Style: Rasenshuriken

Y/n creates a rasenshurken and throws it straight through the bone field destroying it

Kabuto: Tayuya! Demon Flute: Chains of Fantasia!

They all find themselves in a genjutsu

But they are able to escape the genjutsu and blend into the shadows

Itachi: I shall now engage the Izanami

Itachi uses the izanami as they all think it is over and done with but Kabuto comes out from Orochimaru's snake body and slashes at the edo Itachi

Itachi: Sasuke....

Kabuto goes in for a hit but Y/n uses his Kurama hand and slashes down at Kabuto making his dodge

Kabuto: I see...so the nine tails is yours to wield Y/n...I'm impressed

Itachi and Sasuke were shocked

Sasuke: Y/n is in control of the nine tails?

Itachi: It was to be expected..

Sasuke uses a fireball jutsu while Kabuto uses a water style jutsu which clash and create steam

Kabuto: Now I've got you!

Kabuto stabs Itachi which then allows him to use the Izanami which causes Kabuto to go through the same thing over and over and over again (like Deja vu)

Itachi makes Kabuto do the signs to undo the edo-tensei

Itachi: Edo-tensei release!!

The edo-tensei releases as Itachi starts to walk closer and closer to Sasuke until....

He was right in front of him

Itachi: From here on out know this....I will love you always

Itachi's soul then leaves the body with a smile on his face and descends up.

Y/n: So then Sasuke. What's your next move then.

Sasuke doesn't say anything as he looks up into the sky.

Sasuke: What am I?

Y/n hears the wall crumble as he and Sasuke jump back only to see Jugo and Suigetsu there

Suigetsu: Found you!

Sasuke: You guys..?

Suigetsu: What are you doing here?

Sasuke: Stopping the edo-tensei

Y/n turns away as he starts to walk off

Suigetsu: Isn't that Y/n Uzumaki?

Y/n turns back to look at Sasuke eye to eye. Sasuke was shocked to see that Y/n had a rinnegan in his eye

Y/n: I'm not here to bring you over to the light Sasuke....

Y/n smiles

Y/n: That's someone else's job

Sasuke immediately thinks of Naruto as Y/n teleports away

Suigetsu: What does he mean by that Sasuke...?

Jugo: Y/n Uzumaki...probably the strongest person right now..why would he not deal with us

Sasuke smirks as he understands all that Y/n is talking about.

Thanks for reading guys! Also should Y/n learn either snake or Toad sage mode: (Another vote)
