[Kooljay]

Is there a level that can break Tsukiyomi? No. Then all of them.

 

[Penguin]

SM Naruto is all he can defeat.

 

[A v i]

SM or may be KCM Naruto.

 

[PlasticAngelx]

Is there a level that can break Tsukiyomi? No. Then all of them.

BM and BSM can.

 

[Itachi75]

The reason why I believe Itachi can defeat KCM naruto is that
-
1. they are around the same speed
2. MS genjutsu seals the deal

 

[Adobo]

Is there a level that can break Tsukiyomi? No. Then all of them.

This. But power wise, I'd say SM Naruto, or inbetween that and KCM Naruto.

 

[Beans2]

He can only defeat SM Naruto

 

[Spymoon]

SM naruto is definite. KCM is very unlikely but possible.

 

[Kooljay]

BM and BSM can.

No they can't, Tsukiyomi happens too fast. By the time Kurama realizes Naruto is in a genjutsu, Naruto will already be in a coma.
