Piers is an ex-gym leader who sticks to his convictions and will not be swayed by authority or the concept of glory. He's determined to return the pride to his hometown of Spikemuth and help it thrive. He's a rocker and Dark-type specialist and may feel like an outcast in a region where everyone else seems on board with Dynamaxing. He is fiercely nonconformist and principled and looks out for his younger sister Marnie, supporting her and even covertly creating Team Yell to help out.
