Brock is one of the main protagonists of the Pokémon anime series, serving as a core member of Ash Ketchum's original traveling trio alongside Misty. Originally a Gym Leader of Pewter City, Brock joined Ash as a companion and became the most recurring character in the first 25 seasons of the series aside from Ash and Team Rocket. He is characterized as the levelheaded voice of reason within the group, known for his expertise with Rock-type Pokémon and his extensive knowledge about Pokémon care and training. Beyond his battle skills, Brock is an accomplished cook and caretaker, often providing practical support and advice to his less experienced companions. His personality is generally gentle and pleasant, though he has a quick temper when angered. A notable trait is his tendency to become distracted by attractive women, which often requires intervention from his traveling companions. Brock returned as one of Ash's final companions in Pokémon: To Be a Pokémon Master, bookending Ash's journey as the main protagonist with the same iconic trio that started it all.
