Mad Jack

Jack is a scientist in the field of cryptobiology. While all the other scientists are after bigfoot or werewolves, or other common cryptids, Jack has focused soley on a specific siren, thought to be the last siren in the world. There is the legend of the White Siren, a siren born from an angel and a triton (a male siren in some cultures and a merman in others, which in this culture, it will be a male siren). She is known to have been the soul survivor after all sirens were eliminated by God for being demonic, with her being the only exception, because she wasn't fully siren and also because she was immortal, impossible to destroy or dampen her power fully. Yet, because she wasn't entirely angel either, she was banished to the ocean on Earth forever. Jack made it his mission to find this siren, and he finally did.
