Thesis on Pokemorphs & their kin
by Prof. Oak
True Pokemorphs are those with 3 forms. A normal human form, indistinguishable from a normal person. A hybrid form that looks like a person with pokemon features except for the fact that they generally walk bipedally, they have fully functional hands, and they're facial structure is generally that of a human. In hybrid form it is possible for them to pass as humans so long as they hide all features that are non-human and they're fur color is one possible in humans, claws on their hands/longer teeth/odd colored eyes could be a problem though. This form is the hardest to maintain as it requires a lot of concentration, it's duration can be expanded with practice. The final form is that of the base pokemon. in this form only can they speak pokemon, and they are forced to.
Half-Pokemorphs are those with only 2 forms, Hybrid & Pokemon. see True Pokemorphs for details except hybrid form is their human form.
Hybrids are what their name says they are.
It has been theorized that there could be combo-hybrids, however none are known as of this writing. Theoretical propability of it happening from a breeding of 2 hybrids is 25%.
