Eh Naruto ? He already did it at Vote2. Kurama said that Sasuke reversed what Sage did and created pseudo Juubi and still lost.
portions of bijuu chara=/=the Juubi. Not by a long shot lol.
Actually kurama compared it to exactly the juubi so it must have been a vast amount
OT: obviously sasuke you're giving him naruto's power RSM along with narutos chakra advantage its like giving naruto sasuke's rinnegan and EMS and asking who would win lol if either has the other's powers they're gunna win
