Nephilim are mentioned in the Christian Holy Bible as giant superhuman offspring of the “Sons Of God” and the “Daughters Of Men” In other words Angels, and Humans. In reality Angels don’t have gender, and actually manifested on Earth as both male, and female. Since the Bible was written by men it always has a male-centric take on things. Not to mention that many stories were embellished. That is why there’s no mention of Angels manifesting as females along with the existence of female Nephilim. Just Angels can take any biological form gender, so can they give both to both genders through a human. Although when delivering the word of Omniverse God they usually appeared in male form since society was male dominated in ancient times.
One of the most famous Nephilim was a giant named Goliath thought to be at least 9 feet tall. Skeletons of such giants have been found around the world. In some cases they could also be the offspring of powerful Gods, or even extraterrestrials. The Nephilim were the children of Fallen Angels, and they tended to be evil in nature but not as evil as Demi-Demons, or Demon-Human Hybrids. While Demi-Angels, the children of pure Angels, and humans, tend to be good. Of course there were exceptions like the legendary Paul Bunyan of American folklore. Paul was the last known recorded Nephilim to be born on Earth. However most of the legends written about him were false.
Both Demi-Demons, and Demi-Angels are always well over 6 feet tall but the majority don’t go beyond 7 feet tall unless human genes dictate such a height. So why are the Nephilim pushing 9 feet or more? It’s due to the state of the Angels who mate with the humans who produce them. These lust driven Angels give in to human desires, and let the word of their Lord take a back seat. This causes them to fall from grace thereby technically being Fallen Angels rather than Demons. Fallen Angels manifesting into a biological form in this reality have special DNA that uniquely interacts with a human. In essence genetics that are akin to an Angel-Demon hybrid which are actually more powerful than an average biological form Angel, Demiangel, and of course a Demidemon. The Fallen Angel DNA is why the Nephilim are such powerful giants. Thankfully the magical Angelic powers are actually latent. Although they have immunity to the magics of angelic, and demonic beings. The only known hybrid similar to a Fallen Angel was, created by an Angel, and Demon mating. Her name is Shala the Queen of Halloween. Luckily the powerful Demon-Angel state of the Fallen Angel is temporary as they transition to that of a demon. Once they consummate their union with a human the transition to demon is nearly complete.
Nephilim are considered abominations along with Demi-Demons such as the infamous Anti-Claus. However Demi-Angels are not. Angels who descend to Earth for true love, or who succumb to love while on Earthly missions, are generally given Heavenly consent to create a child. This is why Santa Claus (Saint Nicholas), the most famous, and only known Demiangel to currently exist, is considered a holy being rather than an abomination shunned by the inhabitants of Heaven. These Angels who mate with humans must also have at least equal, or greater love for God, and return to Heaven on their own accord. This is why Demiangels don’t see much of their Angelic parent in biological form. Their loyalty to God, and Heavenly duties outweigh directly raising their kids. However they usually visit every so often, and are always watching over their children from afar. In the case of Santa Claus he understands his father, the Archangel Sarandiel, had a more higher holy calling.
Nephilim are virtually extinct from the Earth today due to better detection of Angels breaking their bond with God. Their large size often gives them away so they must hide deep in forests, canyons, and caverns. The most actually exist in the Underworld of the Dark Gods where Angels cannot reach. They plausibly would be welcome in Hell as well but they are trapped in biological form, and are very independent individuals who prefer to work alone in their own darkness rather than be the Devil’s pawn. It’s said the only an Angel, powerful Demon, high ranking nature deity, Jinn, or other higher dimensional being could take one down on their own.
It’s thought that there are less than 100 Demi-Demons on Earth. Again the Heavenly powers that be are always on alert for Demons ascending from Hell to mate with humans. The last birth of such a being was in 2015. The son of the Devil, aka The Anti-Christ!
