Just look at Naruto in BM. That requires massive chakra plus Kurama even spared a CLONE with chakra. Shadow clones were known to take up alot of chakra. Naruto is in BM mode, Clones, RAsenshuriken.
Chakra regenerates .. Tsunade used up nearly all of her chakra during Pains Rampage, Before she fought Madara, She was fully loaded.
The power of Kurama's is on a different scale of the other bijuus. Naruto backhanded 5 TBB. Thats not in Kurama Mode. In KM Naruto, it took on 5 TBB that were formed into one.
NAruto>Bee because of the tailed beast. BM NAruto v BM Bee and Naruto wins without a doubt. Kurama's chakra allows Naruto to travel at speeds as fast as Minato and strength of Tsunade.
Even if ur small brain thinks that something that happend 16 yrs ago still is in affect, Kurama took on 5 bijuu's that had full chakra, TBB at the same time. Ur stupid logic is saying Kurama at half power took on 5 fully powered bijuus but yet 5 6 7 8 is stronger than Kurama.. Smh
Hachibi was having trouble with the 5 bijuu's. Hachibi even said Kuramas Hella strong is Powerful. Hachibi stepped out and Kurama had to step in and finish the job. I mean ur saying Hachibi's stronger than Kurama then why is it that Kurama took them on and no hachibi? Hachibi even wondered if Kurama would help
Now you stated that 5 6 7 8 are stronger than Kurama. Kurama took on 5 and 6 by him self along sides 2 3 4 tailed bijuus.
Narutos the only ones that havnt been absorbed up by Gedo. Bee lost one tail. If he's weaker than 5 6 7 8 why is it that they're sealed up & dead (except for bee of course) and Naruto's not?
You had your diagram wrong it should be more like this:
Kurama at Half Strength > 1 2 3 4 5 6
Kurama at Full Strength > 1-8
Note* I keep bringing up Hachibi because he's the 2nd strongest bijuu to Kurama and showing what Hachibi couldnt do that Kurama did do. Not saying he's weak.
