Nephilim

"When people began to multiply on the face of the ground, and daughters were born to them, the sons of God saw that they were fair; and they took wives for themselves of all that they chose. Then the Lord said, "My spirit shall not abide in mortals forever, for they are flesh; their days shall be one hundred twenty years." The Nephilim were on the earth in those days—and also afterward—when the sons of God went in to the daughters of humans, who bore children to them. These were the heroes that were of old, warriors of renown."

- Genesis 6:1-4 The Nephilim, singular Nephil, are a race of hybrid creatures who are part-human and part-angel. They are the children or descendants of an angel and a human.

Similar to demigods, the human heritage of Nephilim renders them biological organisms and vulnerable to death. while their divine blood endows them with special abilities. In contrast to demigods however many Nephilim are inhuman looking giants.
