Pokemon types and levels

Pokemon types and levels are things people talk about within the world. Types are an actual manifestation of the pokemon's interaction with the energy that powers their abilities (which is their life ****, also known as Infinity Energy). These energies are what distinguish moves from just lashing out, making them much more potent: any pokemon with a mouth can bite, but it won't be nearly as effective as a pokemon using the move Bite. Levels are an abstract measurement of the amount of that same energy that the pokemon has, as well as how effectively they can use it.

A small number of humans can use this same energy. Psychics and martial artists that learn to fuel their strikes with fighting type energy are the most common examples, but hex maniacs (with ghost type abilities) and aura guardians are also well known. It is believed that these are the most common because humans naturally have minds, bodies, and spirits to interact with those energies, but lack any natural way of interfacing with, for example, fire.
