Yami the Shadow Rayquaza Pokemorph
The First Rayquaza Pokemorph, for unknown reasons, he became a Shadow Pokemorph with a strange Power, similiar to a Vampire Drinking blood from beings, Yami can drain the energy from Any Pokemorph if he bites them, killing them if he bites long enough and adding their powers to his own.
When he first ran into the Space Warrior's, he soon sets his sights on Hinaten to make her his bride because he taste her energy and found hers to be perfect. He marks her with not only a bite but with a strange serpent mark on her neck. Right now he has no alliances.
In simple terms, he is Hinaten's Lucifer.
Yami can use three different kinds of bites, the first which is when his Fangs glow Green, allow him to drain the energy from Pokemorphs. The Second which is when his Fangs glow red, can act like an Aprodisac, which can cause the Pokemorph he bites no matter their age, to go into a frenzy, just like what happened to Roscoso and Marissa as well as Katie and Justin. He nearly got Hinaten with this bite, but Hikari Ino stopped him.
