Brock (Japanese: タケシ Takeshi) is the Gym Leader of Pewter City's Gym, known officially as the Pewter Gym. He hands out the Boulder Badge to Trainers who defeat him. He specializes in training Template:Type2 Pokémon.

In the games

Art of Brock from Pokémon Red and Blue

Brock's title is "The Rock-Solid Pokémon Trainer." Brock is quite proud of his rock-hard willpower, and uses Rock-type Pokémon to complement this.

Brock is one of the few truly serious professional Pokémon Trainers in the Pewter City area. He's tough, people respect him, and most admire him. Supposedly, it's hard to get him to laugh or drop his serious demeanor, but when he does, he can't stop.

Brock likes to dig for fossils in Mt. Moon, which is possibly how he ended up getting a Kabutops and Omastar in Generation II (in the Pokémon Adventures manga, he is stated to have found Kabutops as a Kabuto guarding the Pewter City Museum).

In each game, there is only one other Trainer in his gym: a Camper, whose name is Jerry in Generation II and Liam in Generation III. This Trainer usually isn't devoted to the Rock-type, and may use pure Template:Type2 Pokémon like Sandshrew and Diglett.

In addition to the Boulder Badge, Brock gives out TM34 (Bide) for in the Generation I games, and TM39 (Rock Tomb) for the Generation III remakes instead. While he doesn't give out a TM in Generation II, however, for the Generation IV remakes he gives out TM80 (Rock Slide). In both the Generation I games and their Generation III remakes, one Trainer will not allow for Trainers to pass onto Route 3 until they have defeated Brock. Instead, when Trainers try to leave, he will lead them all the way back to the Pewter Gym.

In Pokémon HeartGold and SoulSilver, after he is defeated, he will offer to trade a Rhyhorn that knows Thunder Fang for a Bonsly. He can be found in Diglett's Cave near Pewter City every day between noon and 3 PM, and will offer his Pokégear number if he is spoken to. If he is called on Saturday evening, he will be up for a rematch at the Fighting Dojo.

In the anime

Main article: Brock (anime)

In the anime, while, like later Gym Leaders, Brock appeared primarily as an opponent to Ash in his debut episode, unlike them, he requested to join Ash on his journey, aiming to be the world's greatest Pokémon Breeder, and leaving 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 series, then left briefly during the Orange Archipelago arc to assist Professor Ivy. 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.

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 Pokémon battles is great, causing him to often referee matches between Ash and others. Brock also fancies himself as somewhat a ladies' man, though each time he hits on someone, he is either rejected outright, pulled away by Misty or Max, or, most recently, Poison Jabbed by his Croagunk.

In the manga

In Pokémon Adventures

Brock debuts in Onix is On! of the Red, Green & Blue chapter, however he is mentioned earlier by Blue in Wanted: Pikachu! about being bored by no-one being able to defeat him, or even get past the preliminaries. To gain access to Brock, a Trainer must win several rounds of battles against special Trainers of the Gym, and all of those battles are watched by him from a special room.

Brock is a brave Trainer, and he assists Erika and Misty in their battles against Team Rocket. He also gave Yellow a Graveler after the good Gym Leaders of Kanto battled Agatha's mind-controlling Gastly. However, he is also shown to be quick to anger and restless in his search for a good battle, and when discovering that Red's Pika, the only remaining Pokémon of his, was disobedient, deemed his wins "dumb luck" and sought for a finisher attack instantly. However, when the boy begins to gain his Pokémon's trust, it chooses to fight for him and defeats his Onix.

After Blaine figured out that Red must have been at Mt. Moon before going missing, Brock volunteered to search there, since Mt. Moon was closest to Pewter City. He then found a cast of Red frozen in ice there and contacted Blaine. Before all of the information could be exchanged, he found out that Pewter City was under attack by a group of Bruno's Machop that was searching for Brock's Boulder Badge, and he left to protect it.

A few years later, he, along with Erika and Misty, traveled to Johto for the Gym Leader Tournament at the Indigo Plateau, where he faced off against the expert of the newly discovered Steel-type, Jasmine. He lost the match and later fought against Team Rocket on the Magnet Train.

Aside from being a Gym Leader, Brock also works as a security guard at the Pewter Museum of Science.


This listing is of Brock's Pokémon in Pokémon Adventures.

On hand
Brock's Geodude (×6)
Geodude (×6)
Brock owns six Geodude, nicknamed Geoone, Geotwo and Geothree and so on. The often grasp each others wrists in order to circle around Brock in order to protect him. During the Gold, Silver & Crystal chapter, they used their Magnitude to stop the Magnet Train. However, the impact sent it off course, causing it to almost crash before it was saved by Red's Lax.
Debut Onix is On
Brock's Onix
Onix is arguably Brock's most powerful Pokémon and is apparently well known for its speed, which causes shock waves when it moves. Onix was first used in battle against Red's Pika. Despite the type advantage, Onix was defeated by the small electric type after it came to fight for Red of its own will. Three years later, Onix was sent out by Brock to use as a bridge when a bridge in the Tohjo Falls went out while Brock, Erika and Misty were heading to Johto, during which Misty is joined by Suicune. However, it itself collapsed when they were all attacked by a large group of Zubat, Golbat and Crobat. Once the group finally made it to the Indigo Plateau, Brock used Onix in his battle with Jasmine. It lost to Jasmine's Steelix, which he initially mistook as an Onix of a different variety due to its rock covering used to hide the fact that it was a new, undiscovered species at the time. Its known attacks are Rock Throw, Skull Bash and Bind.
Debut Onix is On
Brock's Kabutops
Brock met Kabutops when it was a Kabuto in the Pewter Museum of Science during the Elite Four's invasion of Kanto, and received and later evolved it for protecting it during the ordeal. It knows many ancient attacks and is a very powerful member of Brock's team and was able to easily hold its own against Jasmine's Amphy, nearly winning him the match.
Debut Light Up My Days, Chinchou!
Given away
Brock's Graveler
Brock's Graveler was first seen as it watched Red battle the trainers in the Pewter Gym. Later on, Brock gave it to Yellow, who has since evolved it into a Golem.
Debut Onix is On

In Electric Tale of Pikachu
