Howrse-Mystery Horse

I bet a lot of you are wondering who the Mystery horse is.... You already know about 8 of the 9 Greek Mythology wandering horses, Aphrodite, Apollo, Athena, Hades, Helios, Dionysus, Hephaestus and Zeus. But there is another horse being released in 9 days. I have a really good guess for who the horse is and I am going to give you my theory, since there are three main gods who are brothers, Zeus who rules the sky, Poseidon who rules mainly the sea, and Hades who rules the underworld, The mystery horse must be Poseidon. If they already have Hades and Zeus they can't leave him out. So brace your self for Poseidon.
