Mormon theology doesn’t really do incarnation. Latter-day Saints believe in an embodied God and that (nearly) all humans will be resurrected to perfect bodies after this life and inevitable death. Latter-day Saints are also not Trinitarian and see Jesus and God the Father as more distinct than most Christian traditions do. Between those two beliefs, Jesus’s taking on a mortal body is not really a big deal—it’s kind of par for the course for any human, whether or not they are the Savior of the world.
