That is not explaining. That's like if I just said,
Obito would rape Madara.
I'm not explaining anything.
How does Madara counter space time ninjutsu?
Ohh I didn't read the OP. You mean EMS madara and obito if he never saved kakashi and died.
Let me use my plot no logic and work this out.
Hashirama chosen younger son. Naruto chosen younger son.
Madara chosen older son. Sasuke Chosen older son.
Obito uchiha version of naruto.
Hmm according to plot no jutsu obito wins. Has the same will as naruto and based on what kakashi and tobi can do with his eyes. Obito wins.
If it was Edo madara however he would rape obito
