@Mitchmaster25 Six Paths Sage Mode has the Rinnegan marking, and All Tailed Beast Chakra Mode has the nine magatama marking, and since Naruto didn't have either after Kaguya battle, then there can only be two options: Sage Mode & Nine-Tails Chakra Mode, or Sage Mode & Kurama Mode.

The mode in The Last is probably Sage Mode & Nine-Tails Chakra Mode since it has the Toad eye marking and it doesn't have the black undershirt.

The mode in Gaiden is probably Sage Mode & Kurama Mode since it has the black undershirt.

The modes in Boruto is probably Sage Mode & Nine-Tails Chakra Mode and Sage Mode & Kurama Mode respectively since the first mode he doesn't have the black undershirt and in the second mode he does.

As for not having the Toad eye marking, maybe Naruto mastered the Toad Sage Mode, where the markings disappear or something.
