This would mean pre-rinnegan Obito and his six paths.please tell me how can the 6pop fight 6 bijuu when there bodies where getting destroyed by naruto punches in base rasengan plus obito has better controll over the mazo did nagato does also if where talking about nagato
6 bijuu plus obito combo will get his intervals
