Hey you haven't won yet. Now m presenting the final analysis..
1. Kakashi when fought wid kakyzu, read thru all his attacks, first destroyed one heart, then He dodged or blocked all his elemental attacks as I proved before, so if it's one on one kakashi would surely win.
2. You said that there should be a water source for darui and kakashi to use water... While I proved you that darui and kakashi dnt need a water source, they themselves are a source.
3. KakaShi can deal wid the 3rk raikage and sand, if he kamuis it, then sasori would be alone. Hence kamui is an advantage.
4. You said that his needles are dipped in poison, if they're re dipped in water, poison would be removed.
5. Earth style of kakashi can easily be a shield for poisoned needles.
5. Darui has black lightning, u said that it would only electrocute the puppets but reminding you that it is gnna turn the wooden puppets to ash.
6. DARUi Has JINKAKu,s AND KINKAKU,s SEALIng TOOLS, WHICH IZ A GREAT ADVANTAGE.
7. Kakashi and darui both r quite genious who can think real fast and make some strategy and analyse the enemy !!!!!!
8. Majority iz authority
9.Darui and kakashi together would make some great combos*
10. Hence all your comments are either proved wrong or can be easily countered.
SORRY PAl but this proved that kakashi and darui would win ..... No problem, better luck next time!!!!
