Mason is in charge of protecting a Pokémon preserve on Mt. Silver. It's the same preserve where the Pokémon Poacher Brothers kidnapped Ash's Larvitar when it was just an Egg and severely wounded the Tyranitar that was Larvitar's mother.
Mason made it her mission to stop the poachers from hurting any more Pokémon. With the help of Ash and his friends, Mason was able to track down the poachers and capture them once and for all.
