Pretty much as the title says
Just like Obito couldn't use Kamui when he became the Juubi Jinchuuriki, do you think Madara's susanoo was affected in the same manor?
I am pretty sure Kishimoto will nerf it. I mean a TTJ PS sounds extremely haxed and Madara is haxed enough as it is, right?
It'd have to be at least as tall as the Juubi
