He biased because he can't make powerful characters play by their own strength, Those feat I post for Madara and Kaguya is not accordance to their exact power level. Kishi can make MC stronger than anyone OK. But before that happen he must play fair to another characters especially the strongest one. Because that I brought DB comparison he. DB villain are able to show us their full potential as their Hype but not in Naruto.the guy makes the manag.he made every character in it and obviously the main character has to be the strongest.how can he be biased.
Kaguya have more chakra than Juubi, instead do any powerful technique, Kishi make her using dimensional switch countless time. And then come the result of Low in chakra. What is that? not make any sense.
You can make the most powerful MC in whole fiction but give a fair chance to another characters.
Thanks.
