Angels and demons possess a number of abilities, such as super strength, speed endurance and other enhanced physical abilities. Where they differ is that one serves God in heaven while the other serves the interests of hell. Therefore, angels and demons have developed opposing energies, preventing them from procreation with or among each other. To get around this, an equilibrium is needed to create a state in which opposing forces are balanced. Humans are a tabula rasa, a basic genetic template that the angels and demons are built off of. This explains the compatibility between the three species. A human vessel would serve as this balancing force, keeping both angelic and demonic from overwhelming and destroying each other. Pieces of an angel's soul were placed inside this human vessel, countered with parts from a demon soul. These opposing forces were successfully contained by this vessel, changing it into what is called a nephilim. This new creature is something of a Frankenstein, containing the parts of all three progenies, but becoming a new species altogether. As this creature is only part angel and demon and contained in a human vessel, it should be weaker than full angels or demons. However, this being has the potential to be stronger than both divine species in terms of power. How can combining these opposing elements make the resulting creature stronger?
