I don't think there any such people akin to Christ. As far as my knowledge goes most religions either explicitly teach against that - that God can enter our reality(because He is completely transcendent, or Holy, thus it's either impossible for Him, or beneath Him, to do so), - or they don't define said "Godhood/Divinity" and said "Incarnation" in the sense in which Christian define Divinity/Godhood and the Incarnation.
For example, Hindu and Far Eastern religions fall into the category of heresy, whereby they enter modalism, or Nestorianism, or monophysitism. Any incarnation in their view is either the Unitarian God enters a different mode of existence, but is still one person(modalism); or that the incarnation itself results in the two natures(human and Divine) be disjointed, rather than united perfectly(Nestorianism); or that the incarnation of the God results in one nature, which is a fusion of both, or the incarnation itself is the God, who mimics human being, rather then truly becoming man.
I could be wrong, of course, because I have not studied those religions in such depth. But reading in general about how they understand their theology, they do fall in the category of these three, which Christians consider false, thus define the Incarnation, and the Trinity subsequently, as perfect union of human nature and Divine nature in the Person of Christ, who is the Son of God the Father, thus Second Person of the Triune Godhead.
