What can be done to stop Madara?

[Fair Warning]

What can be said or shown to him to make him realize his shitty plan is shitty?

Beside violence.

 

[Uchiha Style]

Johan Liebert(Monster)

lol, Madara will probably beat the living shit out of him after hearing him though.

 

[Naruto99Uzumaki]

trapped in izanami forever

 

[rollin]

Naruto and sasuke having a fight, not killing each other and deciding to cooperate together
Making madara realize that cooperation isn't a silent fight and that he shouldn't have become uchiha and senju

 

[WhiteMangekyou]

Izuna or Sasuke will show up and convince him not to screw up the world.

 

[Draw]

Sage of the six paths. It's cliche but at one point it was a really cool idea but he is going to give his power to naruto temporarily it is inevitable we are going to see him and naruto in a god mode

 

[Jako98146]

Kishi deciding to make him arbitrarily give up

 

[Seventh Sama]

The jutsu hashi gave to sasuke could immobilize him.

 

[SIR HERDERP PRESIDERP SDO]

Jūbi dooby doo

 

[sagemode jinchuuriki]

Madara bringing back the final form of the Juubi revealing that the sage actually made a deal with it to stop the violence. Than the Juubi turning around and forcing Madara to resurrect Naruto and Sasuke so they can pick up the test that Madara, Hashirama, Tobirama, and Izuna failed by warring against each other

 

[Mr Hiru]

What can be said or shown to him to make him realize his shitty plan is shitty?

"Kai". And so, he will awake from the Tsukiyomi he casted on himself before dying on VotE. And so, the manga will end.
