So EMS madara vs 5 kage? Madara lolstomps. He could have killed them at any time. They cant do anything against perfect susanoo. Hashirama also stated that madara was regaining his past strength when he was revived meaning likely his physical stats were above his edo tensei form.
Overall with out with EMS madara trumps 5 kage. Any time they try to seal him, he will use perfect susanoo and they are dusted.
