What would be Naruto/Sasuke's Karma abilities...

[Dreemax]

...if either of them somehow managed to kill Kaguya?

Just from observation in the manga (and recent clarification from Momoshiki himself in the recent episode) between Boruto/Kawaki, their newfound abilities from the mark in their palm is no different from Momoshiki's absorption abilities so its highly probable that killing a member of the Otsutsuki clan somehow passes on their abilities to you.

Thoughts?

It would seem that way with Boruto, but Kawaki's karma seal does the same thing as Boruto's (absorb and release) and we don't know who Kawaki killed to get his seal (if that is definitively the requirement for getting one).

 

[Naruto X Hunter]

Sasuke basically has watered down versions of Kaguya's main powers. RinneSharingan-Tomoe Rinnegan, Portal opener, & teleportation.

We know that Boruto's Karma seal gives him the ability to absorb techniques and shoot them back many fold stronger and that seems to be commonized in the seal procurement, so they're definitely getting that, commencely. The other ability is probably another knock off of the Rinnegan. Probably some unique-to-user technique analogous to Amenotejikara/Limbo in terms of OPness. And there may be more similarly op abilities installed if it's to be a great source of power to the MC.
