Piers initially appears to be quite a glum and lethargic-looking person, seemingly keeping a dull expression and having a rather apathetic attitude towards most things. Due to his general lack of attention, Piers did not notice that his Gym trainers had formed Team Yell and went around Galar causing trouble for Gym Challengers. Piers is rather blunt, often calling out others on their flaws. Although Piers doesn't consider himself a good Gym Leader, multiple Trainers such consider him great.
