If Naruto fires a Flash Bijuu Dama at that supercharged one, assuming he's close enough to fire it off and land it before Kurama can charge and fire his off, which is unlikely since he made that one in pretty much just a few seconds, and Naruto's Bijuu Dama actually has to be charged, fired, and it has to reach it's target, then they'd possibly both go bang, severely damaging everybody involved in the fight, or it wouldn't budge Kurama's due to the ridiculous difference in size, and then he'd just fire his off, and wipe Naruto off the face of the planet.
But like I said, doubt he'll do this before he can fire...so...yeah.
It's still more than enough to prove my point. Naruto does not have more firepower than an intelligent Kurama. People have said this for the longest time, yet I've seen no statement that proves that, and feats not only don't prove that, feats disprove it.
Five tailed beasts had already charged up their super bijuu dama before Naruto even started charging his flash bijuu damaYou must be registered for see links. Not only did he match that bijuu dama speed, but he matched it in size and destructive power too. Naruto can charge and fire offYou must be registered for see linksmuch quicker than he can form his flash bijuu dama. You can see by the amount of panel time how longYou must be registered for see linkstook to form (let alone fire)....not only that, but the bijuu dama in the last scan is no larger thanYou must be registered for see linksbecause that's only 50% Kurama, so 100% Kurama's massive TBB would take even more time to charge up.
So based on that, I think it's fair to say that ordinary TBB or continuous TBB knock back Kurama's bijuu dama as it's being charged and it backfires on Kurama, giving himYou must be registered for see linkstreatment.
Well, no actually it doesn't, because we can calculate how much Bee contributed toYou must be registered for see links...which was nothing more than an ordinary TBB. Which makes it almost entirely Naruto alone who did that. Considering flash bijuudama matched a collective bijuudama of 5 tailed beasts (and no bijuu other than Kurama can make a TBB above normal size on their own) Bee's contribution to that was pretty minimal.
