The Pokémon universe is a fictional continuity construct that exists in stories and works of fiction by video game company Game Freak.
 The concept of the "Pokémon" universe, in both the video games and the general nonfictional world of "Pokémon", stems from the hobby of insect collecting, a popular pastime which "Pokémon" executive director Satoshi Tajiri-Oniwa enjoyed as a child.
 Players of the games are designated as Pokémon Trainers, and the two general goals (in most Pokémon games) for such Trainers are: to complete the Pokédex by collecting all of the available Pokémon species found in the fictional region where that game takes place; and to train a team of powerful Pokémon from those they have caught to compete against teams owned by other Trainers, and eventually become the strongest Trainer: the Pokémon Master.
 These themes of collecting, training, and battling are present in almost every version of the Pokémon franchise, including the video games, the anime and manga series, and the Pokémon Trading Card Game.
Brock, known as Takeshi (タケシ ) in Japan, is a fictional character in the "Pokémon" franchise owned by Nintendo.
 In the "Pokémon" video games, he is the Gym Leader of Pewter City and mainly uses Rock-type Pokémon.
 In the anime series, Ash comes across a man that is later revealed to be Brock's father.
 He explains that Brock wanted to become a Pokémon Master but due to his father leaving, Brock had to take care of his many, many siblings and could not leave.
 This is why he became a gym leader, to stay close to his family.
 His father comes back and states he will take care of the family.
 Brock left his position as a Gym Leader to travel alongside Ash Ketchum and became a revered Pokémon Breeder.
 He later cultivates his skill in medicine.
 As of the latest Japanese episode, Brock is at Pewter City to train to be a Pokémon Doctor.
 He has also appeared in several Pokémon manga series, including "Pokémon Adventures" and the "Ash & Pikachu" manga.
