He will usually place others before him and will help and support his friends even against his better judgment or at his own expense. While he is not shown to battle often, he can understand the situations and strategies in any Pokémon battle, and often explains them to the other characters (and to the viewer), probably because he was once a Gym Leader. Brock always carries books and maps with him, and thus is usually the character who knows where the group is headed and what they can do when they get there, though in Advanced Generation, this role was mostly taken over by the Pokénav.
