Jesus as per the Bible was fully human One nature, he simply come into existence in a different way to the 1st Adam.
Wotsup, no fully human one nature has ever come down from heaven, as no flesh can exist in heaven
1 Cor 15: 46The spiritual, however, was not first, but the natural, and then the spiritual. 47The first man was of the dust of the earth, the second man from heaven. 48As was the earthly man, so also are those who are of the earth; and as is the heavenly man, so also are those who are of heaven. 49And just as we have borne the likeness of the earthly man, so also shall we bear the likeness of the heavenly man.
