Nephilim

"''Nephilim -- An abomination." "'The offsrping of an angel and a human? I though that wasn't allowed."''

- Castiel and Metatron, about Nephilim

Nephilim is a hybrid creature born from an angel and human. Castiel stated that creating a Nephilim is forbidden; however, Metatron revealed in "Clip Show" that there was one existing on Earth. Metatron viewed this Nephilim as an abomination due to her existence being outlawed.

A Nephilim has glowing eyes like an angel, although her glow is somewhat dim and grayish in color as opposed to the bright white or bluish-white glow of regular angels. It is unknown if a Nephilim requires a vessel (as angels do), or if she gained her body from conception. It is also unknown if they have souls like humans or not like angels.

Powers & Abilities

 * Astral Perception - A Nephilim can perceive the true form of angels without harm.
 * Super strength - Nephilim bear enough strength to toss low-level angels around. One was able to throw around a wounded seraph.

Weaknesses

 * Angel Blade - Being technically half-angel, Nephilim can be killed by an angel blade.
 * The Colt - The Colt can kill almost anything in existence.
