Brock is the Gym Leader of Pewter City's Gym, known officially as the pewter Gym. He gives the Boulder Badge to Trainers who defeat him in battle. He specializes in Rock-type Pokemon.
Brock appears in Pokemon Red, Pokemon Blue, Pokemon Yellow, Pokemon FireRed, and Pokemon LeafGreen and Pokemon: Let's Go, Pikachu! and Pokemon: Let's Go, Eevee! as the Gym Leader of the Pewter Gym, which is the first Gym that the player challenges on their journey. He is one of the few truly serious professional Pokemon Trainers in the Pewter City area, and many people respect and admire him. He is quite proud of his rock-hard willpower, and uses Rock-type Pokemon to complement this. He rarely laughs or drops his serious demeanor, but when he does, he finds it hard to stop. In his free time, he likes to dig for Fossils in Mt. Moon. In addition to the Boulder Badge, Brock gives out TM34 in Pokemon Red, Pokemon Blue, and Pokemon Yellow, TM39 in Pokemon FireRed and Pokemon LeafGreen, and TM01 in Pokemon: Let's Go, Pikachu! and Pokemon: Let's Go, Eevee!.
In Pokemon Yellow, Pokemon: Let's Go, Pikachu!, and Pokemon: Let's Go, Eevee!, Brock mentions that he is training to become a Pokemon Breeder, a Trainer class that doesn't exist in these games. This is a reference to the goal of his anime counterpart. In Pokemon: Let's Go, Pikachu! and Pokemon: Let's Go, Eevee!, he decides to postpone this goal to have daily rematches with the player after they've become Champion.
In Pokemon: Let's Go, Pikachu! and Pokemon: Let's Go, Eevee!, Brock is also met in Celadon City, where he gives the player the Tea required to enter Saffron City. During this encounter, it is also revealed that he is obsessed with pretty girls, just like his anime counterpart.
Three years later, in Pokemon Gold, Pokemon Silver, Pokemon Crystal, Pokemon HeartGold, and Pokemon SoulSilver, Brock remains the Gym Leader of the Pewter Gym, which can be challenged at any point during the player's travels through Kanto. He is surprised to hear that the player is from the Johto region, and happily accepts their challenge. While he doesn't give out a TM in Pokemon Gold, Pokemon Silver, and Pokemon Crystal, he gives out TM80 in Pokemon HeartGold and Pokemon SoulSilver.
In Pokemon HeartGold and Pokemon SoulSilver, after all 16 Badges have been obtained, Brock can be found in Diglett's Cave near Pewter City on any day between noon and 3 PM, and will offer his Pokegear number if spoken to. If he is called on Saturday nights, he will be up for a rematch at the Fighting Dojo in Saffron City. After his Pokegear number has been obtained, he will reappear in Diglett's Cave every day between 5 PM and 8 PM, and the player can have a photograph taken with him there. If he is spoken to in Diglett's Cave on a Saturday, he will offer to trade a Rhyhorn that knows Thunder Fang for a Bonsly.
In Pokemon Black 2 and Pokemon White 2, Brock appears alongside the other Gym Leaders of Kanto as an opponent in the Kanto Leaders Tournament at the Pokemon World Tournament. He also participates alongside the Gym Leaders of Kanto, Johto, Hoenn, Sinnoh, and Unova in the World Leaders Tournament, and other Rock-type experts in the Rock Type Expert Tournament.
In the anime, like later Gym Leaders, Brock appeared primarily as an opponent to Ash Ketchum (Yuri Lowenthal/Rica Matsumoto) in his debut episode; unlike later Gym Leaders, he requested to join Ash on his journey, aiming to be the world's greatest Pokemon Breeder. In doing so, Brock left the Gym in the hands of his father, Flint, who had finally revealed himself to have returned from his journey. Brock advised Ash throughout the Kanto region, then left briefly during the Orange Archipelago arc to assist Professor Ivy (Mary Elizabeth McGlynn/Keiko Han). He returned to Ash's side in Johto, and with brief returns to Pewter City at the end of each series, joined him for his journeys in Hoenn and Sinnoh as well. However, towards the end of Pokemon the Series: Diamond and Pearl, Brock decided to become a Pokemon Doctor and parted ways from traveling with Ash. Despite this, Brock reunites with Ash from time to time, meeting up with him in Pokemon the Series: Sun and Moon. More recently, he reappeared in Pokemon Journeys: The Series for a four-part special set in Sinnoh.
Brock mainly provides an advisory role to the other main characters of the anime, being several years older than the rest of them. His knowledge of Pokemon battles is great, causing him to often referee matches between Ash and others. Brock also fancies himself as something of a ladies' man, though each time he hits on someone he is either rejected outright; pulled away by Misty (Rachael Lillis/Mayumi Iizuka) or Max (Amy Birnbaum/Fushigi Yamada); or, more recently, Poison Jabbed on the back or the kiwis by his Croagunk.
Not much is known about Brock's early childhood. In Having a Wailord of a Time, he revealed that his first Pokemon was an Onix he received as a tenth-birthday gift from his father Flint.
When he was younger, he participated in Little League Baseball, as mentioned in The Little Big Horn.
Prior to joining Ash at the end of Showdown in Pewter City, Flint left the family home to pursue his own ventures. As a result, Brock assumed the responsibility of running the Pewter Gym while also taking care of his nine younger siblings on his own.
In Showdown in Pewter City, after Brock awarded Ash the Boulder Badge, Flint came forward and confessed who he was. Flint took on the responsibilities of the Pewter Gym and his family, leaving Brock free to journey with Ash and Misty.
Brock only became the Gym Leader because he felt it was his responsibility, and he admitted to Ash that he would rather care for Pokemon than battle them. It was his dream to become a great Pokemon Breeder, and when Flint took back control of the Gym, Brock was allowed to start following this dream.
Brock was also able to meet and make advances towards the many beautiful women he met. At first, he was more casual about approaching women, such as Officer Jenny in The Water Flowers of Cerulean City, and more modest as well, such as when he met Melanie in Bulbasaur and the Hidden Village. However, he became more open and passionate towards almost all single young women as time progressed.
Brock took care of a Vulpix that belonged to a Breeder named Suzie.
Brock briefly left the show during the Orange Islands saga to work for Professor Ivy on Valencia Island and so is only seen in a couple of cameos in the second movie. While there, something happened that will probably remain secret as Brock will only huddle and say "that name" whenever he is asked about it. In the English dub of Destiny Deoxys, he mentioned his work for her. After this incident, Brock returned to Kanto where he was found by Delia Ketchum, who helped him to regain his strength. Brock then became a rival to Mimey until he rejoined Ash and Misty as the three traveled to Johto.
In Beauty and the Breeder, Brock returned Vulpix to Suzie. Together, they entered Vulpix into the Pokemon Beauty Contest in Bonitaville.
At the end of Ash and his friends' journey in Johto, the three went their separate ways, with Brock's help requested at home by his father.
Upon his return home, Brock was dismayed to find that his mother had returned and commandeered the Gym, turning the Rock-type haven into a brightly decorated Water-type den. Brock battled her for the honor of Rock types and won, promising his brother Forrest that he would become Gym Leader someday.
After that, Brock returned to follow Ash through Hoenn, along with their new friends May and Max, and then through Kanto again as Ash took on the Kanto Battle Frontier. He left briefly when Pokemon the Series: Ruby and Sapphire ended in order to visit his home, but quickly returned to travel with Ash and Dawn (Kath Soucie/Megumi Toyoguchi) in Sinnoh. Near the end of the Sinnoh saga, Brock began to show interest in becoming a Pokemon Doctor, and so, rather than following Ash to Unova to advise him, decided to remain in Kanto to study.
Brock made an appearance in DPS02, where it was revealed that, while waiting to attend a Pokemon medical school, he had been studying hard at home as well as helping out at the Pewter City Pokemon Center. In the episode, he played a major role in helping Forrest to officially become the Pewter City Gym Leader when it is revealed that his father never informed the Pokemon League of the title change.
Brock reappeared in a fantasy in Expedition to Onix Island!, when Dawn learned that Cilan (Mitchel Musso/Mamoru Miyano) cooks for himself, Ash, and Iris (Eileen Stevens/Aoi Yuki). She said this was similar to the way Brock used to for her and Ash before he decided to become a Pokemon Doctor. He also appeared in flashbacks in The Mystery of the Missing Cubchoo! and The Fires of a Red-Hot Reunion!. In addition, he appeared in a fantasy in The Dream Continues!.
Brock appeared in person in BWS01, where it was revealed that he had attended the Pokemon medical school and had been sent to Johto to apprentice under a Pokemon Doctor as part of his training. While passing through the town he bumped into Pokemon Connoisseur Cilan briefly, then encountered him again when Cilan took his Pansage to be treated at the town's Pokemon Center after it was injured by a Gyarados. While waiting for it to recover, the two encountered the beginning Trainer Ayumi who was having trouble teaching her Pikachu to use Thunderbolt; Brock was very impressed with Cilan's talents as Cilan helped Pikachu master the move. Later, when the Gyarados that Cilan encountered earlier started to rampage due to being injured by the poacher Amer, Brock spotted that it was injured, so after Pansage's Grass Whistle put it to sleep, Brock was able to quickly treat it. Afterwards, the two said goodbye to each other and continued their separate travels, having never learned their names or that Ash was a mutual friend of theirs.
Brock reappeared in several Pokemon the Series: Sun and Moon episodes, first reappearing with Alola, Kanto!. Brock reunited with Ash when he and his classmates arrived at the Kanto airport, where he also used his expertise as a Pokemon Doctor to diagnose Lillie's (Megan Taylor Harvey/Kei Shindo) Snowy's airsickness as harmless. Brock and Misty then compared Kantonian and Alolan Pokemon with the class at Professor Oak's (Tom Kane/Kenyu Horiuchi R.I.P. Tim Conway and Unsho Ishizuka) Laboratory. Later, Brock and the rest of the group worked together to defeat Team Rocket, who Brock was angry to find were still up to their old tactics of stealing Pokemon. Afterwards, the group had a party and learned from Professor Kukui (Abe Goldfarb/Keiichi Nakagawa) that the class had plans to head to Cerulean City for a Gym battle.
In When Regions Collide!, the group arrived at Cerulean City, where Brock and Misty assisted Professor Kukui's lecture on the mechanics of Gym battles and the Pokemon League. Brock defeated Lillie and Sophocles (Charlie Schlatter/Fumiko Takekuma) in a Multi Battle, then used his Mega Steelix to defeat Kiawe (Travis Willingham/Kaito Ishikawa) and his Turtonator. He and Misty then bade Ash and his classmates farewell and accepted Ash's offer to visit Alola sometime in the future.
In Alola, Alola!, Brock accompanied Misty to Alola and met up with Ash and his classmates. Stopping by the Pokemon Center, he flirted with Nurse Joy, only to be stopped by Misty. He remained behind to assist Nurse Joy as she treated a Yungoos.
In Heart of Fire! Heart of Stone!, Brock and Misty accompanied Ash and his classmates to Akala Island. They visited Paniola Ranch, where a Kangaskhan was threatening the Pokemon after its baby was injured. Using a Comfey that Nurse Joy had given him, Brock was able to treat the baby Kangaskhan's injury. Later, upon meeting Kahuna Olivia (Claudia Black/Miyuki Sawashiro), Brock immediately fell in love with her and they agreed to a battle. Brock used Sudowoodo against her Lycanroc, but the battle was interrupted when Team Rocket attempted to steal the Pokemon. Brock teamed up with Olivia to turn Lycanroc's Continental Crush into the shape of a heart, which defeated Team Rocket. At the end of the episode, Brock returned to Kanto alongside Misty.
Brock's silhouette appeared in Destination: Coronation!, alongside the other Kanto Gym Leaders as the narrator explained how the Gym Leader system works in the Pokemon world.
Brock was briefly referenced by Dawn in Nightfall? Nightmares!, when she talked about her journeys to Chloe (Cherami Leigh/Kana Hanazawa). He reappeared in a brief flashback in the following episode, when Dawn explained to Chloe how she got experience from him with treating injured Pokemon. Ash also called him out by name when he and Dawn were asked about how they know each other.
Brock reappeared in The Arceus Chronicles - Part 2, where it was revealed he was working in the Oreburgh City Pokemon Center at the time, with Croagunk and Blissey as his assistants. He later joined Ash, Dawn, and Goh (Zeno Robinson/Daiki Yamashita) in helping to stop Team Galactic's plan to open a hole in space-time to retrieve Cyrus (Sean Schemmel/Kenta Miyake).
In Radio Lulled the Mischievous Stars!, Brock was seen listening to Team Rocket's radio show while camping out in a forest. During the broadcast of the show, a letter he sent was read by Jessie (Rachael Lillis/Megumi Hayashibara). Due to Jessie using a nickname, Brock didn't recognize her, instead feeling happy that the host whose voice he had fallen in love with was reading his mail.
He reappeared in a flashback in Friends, Rivals, Lend Me Your Spirit!.
Brock made a cameo appearance in the ending credits of I Choose You!.
Brock reappeared in Mewtwo Strikes Back - Evolution, where he had largely the same role as in Mewtwo Strikes Back.
In the Legacy of Chris Thorndyke, he has played a role of being a mentor figure for Ash and like a brother figure since that he has been the Gym Leader of Pewter City, and his home was seen as a cameo until that he returned in the fifth saga and battled in the tournament against Lord Orochi and his army.
And he is reprised by Eric Stuart in the English dub and Yuji Ueda in the Japanese dub.
