This page refers to the stat. If you are looking for a trainer as a PC please visit Playbooks or Main Character
The Trainer stat describes how well your Main Character controls and commands their Pokémon and how obedient their Team is. This stat also describes their natural leadership ability, so it may still be rolled when a main character commands a Pokémon they don't actually own.
This stat is essential to the Trainer phase of Battling. It is also used when trying to influence a Pokémon to do what you ask.
This stat is not often rolled to solve a problem, but it may be chosen when the main character has to give a complicated command to a Pokémon, command a large number of Pokémon at once, or take leadership over Pokémon they don't own.
