Pokémon Trainer

A Trainer or Pokémon Trainer (usually capitalised to help distinguish between other words that have the word "trainer" in it), is a person that catches, trains and battles Pokémon, usually collecting badges and challenging a respective region's Pokémon League. However, many humans that have Pokémon are not always Trainers, for example, Ruben Lawton and Martha Mazel take care of Pokémon as pets, often leaving their Pokémon at her parent's house, they can be classed as Pokémon Breeders.
