In the pokemorph world, there are three types of creature, Human, Pokemon, and Pokemorphs.
In this world, instead of having teams of pokemon, a person can only bond with one. There are no such devices as pokeballs for capturing pokemon, so the only way to become a 'trainer' is to bond with one.
However, once a human bonds with a pokemon, they become one with the pokemon, gaining some of its appearance and abilities aswell as up to two of its moves.
Once a human is bonded to a pokemon, that human, now a pokemorph, will share all of its pokemons emotions and feelings. If your pokemon feels pain, so will you, if it feels joyful, you will be able to sense and feel your pokemons joy.
Humans can only bond with one pokemon.
Example:
A human bonds with a Flygon, and this particular pokemorph, gains flygon wings and power of flight, along with a flygon tail and head crest. The two moves in which she gained from becomeing a pokemorph, are Dragonbreath and Iron Tail.
