Re: Why havent Madara or Sasuke copied Kamui?
Because it's a pathetic excuse for Kakashi fans in believing Kakashi can use PS on his own.
When people neglect the very context of both chapters.
CHAKRA IS POWER
it explains everything being used without ocular manifestation.
Madara and Obito's Susanoo, six path Justus, and yin yang release.
All of it...
It's like people saying deva path yahiko copied the rinnegan from Nagato.
Obito's eyes are gone, they're just chakra being manifested through kakashi
