In this fight Obito can use Kamui for both intangibility and full warping. Other than that, it is a no restriction battle with full intel for both, with an intent to kill without any hesitation
Location: Naruto and Sasuke vs Obito
Distance: 200m ( because they are both incredibly fast and possess S/T ninjutsu, putting them in 15-30m distance from the very start of the battle would be too hardcore )
Scenario 1: IC Mindset ( Spamming is not allowed, won't use the most OP techniques right from the start of the fight )
Scenario 2: OOC Mindset ( Can and WILL spam as much as they both can, will use the most OP techniques whenever they want )
Please, discuss.
