This pokemon papercraft is Brock (Takeshi) cube craft, the Gym Leader of Pewter City's Gym, known officially as the Pewter Gym, based on the anime / game Pokemon, the paper model was created by alonso jacobo. Brock hands out the Boulder Badge to Trainers who defeat him in battle. He specializes in training Rock-type Pokémon.
In the games
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 addition to the Boulder Badge, Brock gives out TM34 in Generation I, no TM in Generation II, TM39 in Generation III, and TM80 in Generation IV. In both Generation I and III, a Trainer will not allow anyone to pass onto Route 3 unless they have defeated Brock. Instead, when someone attempts to leave, he will lead them all the way back to the Pewter Gym.
In Yellow Version, he speaks directly to the player about his training to become a Pokémon Breeder after he is defeated, despite breeding not being present in the game. This is a reference to the goals of his anime counterpart.
In HeartGold and SoulSilver Versions, after he is defeated and all 16 badges have been obtained, he can be found in Diglett's Cave near Pewter City on any day between noon and 3 PM, and he will offer his Pokégear number if he is spoken to there. If he is called on Saturday nights, he will be up for a rematch at the Fighting Dojo. After his Pokégear 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 the anime
In the anime, like later Gym Leaders, Brock appeared primarily as an opponent to Ash in his debut episode; unlike later Gym Leaders, he requested to join Ash on his journey, aiming to be the world's greatest Pokémon 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 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; however, he now wants to become a Pokémon Doctor.
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 something of 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.
