Minato defeated him with FTG twice so how can you guys say his s/t is not stronger than Kamui? FTG is superior and OP due to massive speed, counter and consists of reflexes.
I don't see Kamui beating FTG, but Obito may be stronger and faster this time but it doesn't make any sense. If he is stronger and learned more about his jutsus and why can't he use any of Rinnegan's powers? Without Juubi's powers he should be dead by now. FTG never disappears on a target except for some other OP transformation like Oro or any stuff made by shell. Why was he even knocked out by FTG if he tried to use Kamui?
Many of you guys stated he got defeated because he was still young and not well trained....wtf? The 14/15 years old boy who controlled Kurama, went through the barriers, defeated anbu people, AND even has Madara as his teacher. He has Senju DNA and re-read the chapters and look how powerful he is when he knocked out the mist anbus in an instant. So stop complaining, even you are a Minato hater or Obito fanboy doesn't make any sense. This is canon.
