Poseidon

Poseidon is one of the gods of the Monster Girl Encyclopedia world, her domain being the sea and the living creatures within it. Poseidon was originally a deity allied with Heaven and the Chief God, but in the present age she has become a monster herself and thrown in her lot with the succubus Demon Lord.

Patron of an ocean teeming with monstergirls, Poseidon now devotes her time to making life beneath the waves amenable to her worshipers and their husbands. Instrumental in this are her sea bishops; seahorse monsters who can confer on humans the permanent ability to breathe underwater.

Poseidon's change of heart to side with the Demon Lord doesn't seem to have been a consequence of demonic energy corruption leading to monsterization, but rather a conscious decision on the sea-god's part. With "a heart that was broad like the ocean", she grew disillusioned with the Chief God's periodic orders to kill humans with storms and tsunamis, so broke ranks and willingly joined the monsters. Now, being dragged under the waves doesn't end in drowning: Poseidon's magic monsterizes women into nereids, and sustains men until such time as one of her followers arrives to rescue/rape him. The sea god still calls down great storms to shipwreck sailors, but now it's in order to provide males for the monstergirls of the sea to get pregnant with.

During the age of the former Demon Lord, Poseidon was in the vanguard of a great war between Heaven and the demons of chaos. These eldritch demons were sealed in the deepest part of the sea, and even today the abyssal zone lies beyond the reach of Poseidon's power.
