Water Nephilim 1

The Water Nephilim is Armaros's progeny, a Nephilim shaped like a giant squid with a bluish color.

Unlike the other Nephilim, the Water Nephilim is non-hostile and will not begin the process of cannibalism. According to the Freemen's Notes, the Water Nephilim is at peace with itself and loves the world and everyone in it.

At the end of the game credits, it is shown swimming peacefully in the abyss, despite its father being vanquished.
