the kage win, easy diff. think about who he will have to go against and you'll stop fanboying for a sec. he has to face the third raikage, and his son. which means he's gonna have to spam the shit out of his s/t jutsu, which he can only do so many times. he will most likely have to stay in susano for an extended period of time. which will just be a big target for hashirama. with minato and tobirama using their flying thunder god, sasuke just gets slaughtered. half the kage dont even need to join the battle. maybe more than half.
meanwhile naruto's in the corner laughing saying, "bet you wish you had that bijuu chakra again?"
Sasuke isn't going to just be sitting there, while Hashirama is forming the Wood Jutsu, Sasuke would easily Amaterasu Hashirama then Chidori Nagashi any kages coming towards him for cqc.
He would let them believe he is cornered, trapped in the Jinton cube, but then RinneSwap with Hashirama right before the cube detonates, that take care of him...
While the kages are left thinking that Sasuke is dead, they'd notice Hashirama is missing to meet with Minato getting a sword through the skull, as Tobirama proceeds to attempt a speed blitz, Sasuke coats himself in a Amaterasu covered Susano'o ribcage, this either halting Tobirama or forcing him to FTG away, then prepare his Edo Tensei. While, Ay and 3rd Raikage attempt to breakthrough the ribcage, thus needing to sacrifice an arm (leaving Ay armless now). But right before contact was made, he RinneSwap's with Tobirama who would be in the middle of bringing up a coffin for his Edo Tensei, but is now getting backhanded by two Lightning armor Raikage's. Sasuke would pull the sword out of Minato's skull and attempt to dash towards an armless Ay, just to get caught in a Jinton cube, while Muu uses the lightweight boulder Jutsu on the other kages, who attempt to get out of Sasuke's RinneSwap range, Sasuke would then absorb the Jinton cube via Preta Path, surprising Ohnoki, and, taking that moment of weakness to full advantage, he would proceed to use CT on him, making Ohnoki the core, while 3rd Raikage appears behind Sasuke using his Hell Stab, he would grab it with an Ashura Path arm, absorb the lightning cloak through Preta Path, and blast him point blank in the face with a chakra canon.
The other Kages would be in shock about it, as Sasuke sends Amaterasu arrows towards the airborn Muu, which get blocked by Gaara and his father's Sand. While the 3rd Kazekage lifts everybody into the air with his Iron Sand. Sasuke would look at the now flying Kages, while Gaara and his father take advantage of that, surrounding Sasuke with Sand, as Tobirama is getting up from getting backhanded, shooting a large stream of water towards b Sasuke. Sasuke would jump into the air, Muu would look at that as an opportunity, come out of his invisibility, and shoot a Jinton Cube at Sasuke from the air, while sand spikes come at him from the ground forcing Sasuke to activate PS and fly out of the way, the Kages all quiver in fear for a moment before getting some speech from Hiruzen about never giving up, Tsunade (almost forgot about her) would jump towards the PS, while Hiruzen backs her up with a 5 element attack, while Sasuke clashes with Tsunade's punch with a PS slash, the attack would cut through Tsunade just before getting blasted by the 5 elements attack, Sasuke would then fall on the ground, covered in water as Tobirama flooded the ground, to be greeted with a water prison Jutsu.
Hiruzen would fire a lightning Jutsu towards Sasuke, while Mei surrounds the water prison with boiling mist, resulting in a large flash of light from the lightning connecting with the water prison, then the Mist getting blown away, burning Hiruzen slightly. As the mist clears, they would see the deformed body of Mei where Sasuke used to be, as Gaara points out that Sasuke is now in the air with a Chidori in hand. The kages would notice that it begins to rain, and Tobirama thinks "Now we are on my playing field..."
Thunder would roar through the sky, as lightning fills the air, and Sasuke raises his Chidori, "Begone... With the thunderclap"... The kages would look in horror as a large lightning dragon is seen in the sky and a mighty strike of lightning comes down at alarming speeds towards Tobirama and Hiruzen, Tobirama would run towards Hiruzen to try and FTG both of then to safety, as the lightning bursts into the ground.
The airborne kages would be blown away from the sheer force of the impact. As the dust settles, Sasuke would be seen huffing and puffing, and Ay would attempt a falling Axe kick on the exhausted Sasuke, while an Ashura Path arm grabs the leg, and Sasuke begins to suck Ay dry of all his chakra, and Gaara sends sand towards Sasuke to interrupt him, and he uses Almighty push to repel both a drained Ay and the sand away. 3rd Kazekage would send his iron sand spikes at Sasuke, being told of the 5 second gap between almighty push uses by Kakashi. As Sasuke RinneShifts to Gaara grabs his neck, the other kages too afraid to strike Sasuke while Gaara is so close to him, Sasuke proceeds to rip Gaara's soul out, Kakashi drops from the air to try and Chidori Sasuke, but Sasuke simply lifts Gaara into the way of the attack, leaving Kakashi in shock, while Sasuke gets a smirk on his face, then uses Amaterasu point blank at Kakashi's face.
I'm too lazy to finish the rest, it's late and I'm tired, I'll prolly finish the rest when I wake up
