While he very much cares for her, he has an extremely boisterous personality and insists on taking her along in adventures, though as it currently stands, Peonia does not have interest in Peony's 'adven-tours' and wishes to do things her own way. Peony has an odd relationship with his daughter Peonia.
He eventually found his way into exploring the Crown Tundra in hopes of learning more about the many Legendary Pokémon that inhabit it. He was a powerful Trainer who posed a challenge to many, so much so that he even eventually became a Champion, though he left the Pokémon League shortly after Rose became the Chairman. He eventually had his talents recognized and became a Gym Leader, specializing in Steel types.
From childhood, he always felt pressured because he was constantly compared to Rose, who was described as being quite gifted, which caused Peony to become rebellious over time, becoming a delinquent who ran away from home. Peony is the younger brother of Rose, though this is not often publicly mentioned.
