Summery: It starts off with the Team Rocket motto as Jesse, James and Meowth set a trap for Pikachu. They dig a pit and cover it with leaves so it won't be seen. Unfortunately, they couldn't see their own trap and fell into it. As Ash & Misty enter the outskirts of Pewter City, they meet a man named Flint who's selling rocks. Flint notes that Pikachu is really tired and offers to take Ash to the Pokémon Center...for a small fee. After giving his pokémon over to Nurse Joy (the twin sister of the Nurse Joy from Viridian City), Ash notices a sign regarding the Pokémon League and wants to join in. Misty informs him, however, that to do so, he must challenge and defeat gym leaders in order to get official Pokémon League Gym Badges. Once again, Ash swears to become the greatest Pokémon Master and vows to defeat all the gym leaders. The next day, Ash and Pikachu head over to the Pewter City Gym. Inside the rocky building they find Brock the gym leader. Brock sends out his Onix and Ash orders a scared Pikachu to fight. However, Onix easily binds up Pikachu squeezing the cute and pudgy pokémon. Pikachu tries to shock it, but unfortunately, rock-type pokémon are not effected by electricity. Ash tries to call Pikachu back using a pokéball, but Onix's bind prevents it. As Pikachu continues to get crushed, Ash is forced to forfeit the match. Outside the gym, Ash runs into Flint again who explains that Brock is a good trainer and he loves all pokémon. But Brock has never been able to join any competitions, because he is forced to stay in Pewter City to take care of his ten younger siblings. We then see Brock's house where 6 or so squealing kids surround a cooking and sewing Brock. Flint explains further that their mother died and their father left to become a pokémon trainer, but never returned. Ash has second thoughts about beating Brock, but Flint offers to help Ash. At an abandoned hydroelectric plant, Ash runs on the water wheel to act as a generator which Flint connects to Pikachu's cheeks. After a few seconds of deafening high squeals, Pikachu becomes super-charged. Ash comes back to re-challenge Brock and Brock reluctantly accepts, as is his duty as Gym Leader. As the typical battle begins, Ash calls Pidgeotto, while Brock calls Geodude. Geodude easily defeats Pidgeotto, so Ash calls out Pikachu whose super-charge electricity fries Geodude. Surprised, Brock calls it back and brings out Onix. With its super electricity, Pikachu is able to deliver Onix a few hits. However, Onix once again binds Pikachu. Pikachu and Onix seem to be hurting as Pikachu shocks and Onix squeezes. A stray bolt of electricity sets the rafters on the top of the gym on fire. Finally, Pikachu gives out and stops shocking, as Onix continues its bind. Brock wants Ash to forfeit again, but Ash won't stop the match until one of them is declared a winner.  Onix Suddenly, Brock orders Onix to stop, saying that he doesn't want the pokémon to get hurt. The fire from the rafters, however, activates the sprinkler system which weakens Onix. Pikachu shocks Onix weakening it further. Ash is about to order Pikachu to finish him, but all of Brock's siblings beg Ash to stop. Brock tells them to get out of the way, since this is an official match and it must continue until one of them wins. Hearing his own words coming back at him, Ash remembers how Brock tried to stop the fight earlier. Ash then tells Pikachu to stop and declares that he forfeits. As Ash leaves, he is disappointed that he lost but is proud that he did the right thing. Brock stops Ash in the road and gives him a Boulder Badge, saying that he deserved it. He also hopes Ash will continue on his journey in his place to become a great pokémon trainer, as Brock wants to be the world's greatest pokémon breeder. Suddenly Flint shows up and reveals himself as Brock's father. He explains that he never returned because he failed at being a pokémon trainer. But now he wants Brock to go on his own journey. After some farewells and orders from Brock, Brock and Ash take off with Misty following them, and Team Rocket finally gets out of their trap.
