Nephilim

The Nephilim are humans of demonic descent, usually from fiends forcing themselves on humans, though not always. Nephilim are unaware of their powers until the cusp of adulthood and their laten powers kick in automatically. Although Nephilim offspring are usually destroyed at birth, some survive to become grotesque mockeries of their mortal parents. All too rarely though one learns from and takes on the characteristics of its human parent, turning from its evil heritage.

Another name for nephilims is half-demons.
