Ash Ketchum has just become a Pokémon trainer in the Kanto Region. He picked Pikachu because, after breaking his alarm clock, Ash was late for his appointment and all the conventional starter Pokémon were gone. He has a childhood rival named Gary. Ash accidentally destroys a bike belonging to a girl named Misty; she starts to follow him to get her bike back, but soon becomes a close friend. Misty endeavors to be a great water Pokémon trainer. Shortly thereafter, Ash battles Brock the leader of the Pewter City gym. Ash initially loses to Brock's Onix, but wins the Boulder Badge in a rematch. Brock then turns over gym leader duties to his estranged father and accompanies Ash and Misty on their journey with the goal of becoming the world's greatest Pokémon breeder.
Ash's Kanto journey culminates with him collecting the necessary eight badges to compete in the Indigo League Pokémon Tournament held annually on the Indigo Plateau in Viridian City. Upon his arrival Ash shrugs off repeated suggestions that he should spend his time training and preparing for the tournament. He ultimately loses in the quarter-finals to Richie, a new rival who happens to use many of the same Pokémon as Ash, including a Pikachu named "Sparky".
After the Indigo League, Ash returns briefly to Pallet Town before setting out on a new journey to the Orange Islands where he will compete in the Orange League. Brock eventually parts company with Ash and Misty to pursue Pokémon research with Professor Ivy. At this point a new character, Tracey Sketchit joins Ash. Ash collects four badges and competes against the Orange League champion, Drake, a very experienced trainer. The battle comes down to Pikachu versus Drake's Dragonite, which's been tired in challenging Ash's other pokemon, with Pikachu delivering a devastating Thunder attack to score the knockout blow.
Victorious in the Orange League, Ash again returns to Pallet Town where he and Misty are reunited with Brock who leaves Professor Ivy for an unknown reason. Tracey decides to stay in Pallet Town to work with his idol, Professor Oak, while Ash, Brock, and Misty head west to the distant land of Johto. Pokémon: The Johto Journeys marks the introduction of a new series of Pokémon beyond the original 151 named and frequently seen throughout the Kanto and Orange Islands regions.
In fifth season, Ash is defeated by a Pokémon trainer from the southern land of Hoenn region and decides to journey there next after a brief visit home. Before arriving in Pallet Town, Misty receives a message from her sisters requesting that she return to Cerulean City to take over gym leader duties. Brock then decides that he has been away from home too long and must return to help his father take care of his many brothers and sisters. This marks the last time to date that the original trio of friends journeys together.
Back to Pallet Town, Ash receives a more modern-looking outfit from his mother and sets out for the Hoenn region with only Pikachu, choosing to leave his other Pokémon with Professor Oak.
In Hoenn, Ash meets May and her younger brother Max, who join in his journey. May is excited by the Pokémon Contests that take place in Kanto and Hoenn, while Max joins the group to gain experience so that one day he will have his own Pokémon and become a Gym Leader like his father Norman, the Gym Leader of Petalburg City. Having solved his family issues, Brock returns to accompany Ash. This season, Gary leaves his promising career as a Pokémon Trainer to become a Pokémon researcher. Misty visits the group and takes Ash, Brock, May and Max to the Togepi Kingdom. Meanwhile, Team Rocket has been sent by their boss to try and establish a branch of the organization in Hoenn. Along their journeys, Ash and his friends also come into contact with the villainous teams that are in Hoenn, Team Aqua and Team Magma. Finally, Ash participates in the Hoenn League and May in the Grand Festival.
After Ash completes the Hoenn League and places in the Top 8, he returns home to Pallet Town, as do May and Max to Petalburg City and Brock to Pewter City. Ash meets up with Misty, Tracey, Professor Oak, and his mother at his homecoming celebration. Professor Birch and Max arrive in Pallet Town that same evening, and May and Brock arrive the next day. Ash and May learn of the Battle Frontier and the new contests in Kanto region and decide to travel together to compete. Brock, Max, and Misty decide to join them on their new journey; however, Misty leaves the group again in the next few episodes to return to looking after the gym.
After Ash becomes champion of the Kanto Battle Frontier, May as well as Drew, Solidad and Harley travel to the Johto region to participate in the Grand Festival held there. Max returns to Petalburg City to get ready for his own Pokémon journey and Brock returns to Pewter City, once again. Ash learns of a new region called Sinnoh, where he embarks on a new journey. Ash planned to bring only Pikachu, but Aipom snuck on the boat. Brock comes back a few days later in Sinnoh and they both meet Dawn, a new trainer who hopes to become a great Pokémon Coordinator, like her mother. Ash meets a new rival, Paul, who prefers to capture the strongest Pokémon, leaving the weak who are released, in strong contrast to Ash's methods. During the journey, Ash encounters the Elite Four of Sinnoh Region in different places respectively, he carries on battles with them, and also receives their instructions about battle techniques. May briefly returns and travels with Ash, Dawn, and Brock to the Wallace Cup, and Ash meets Gary several times throughout their journey.
Ash and his friends also come in contact with Team Galactic, an evil organization that wants to control the Pokemon universe. Team Galactic has also recruited an evil Pokemon Hunter, known only as J, to help them capture powerful Legendary Pokemon to advance their goals. With the help of the Sinnoh Champion Cynthia, as well as a detective named Looker, Ash, Dawn, and Brock manage to defeat Cyrus, leader of Team Galactic.
After the Sinnoh League, the gang prepares to go their separate ways: Brock is returning to Pewter City to become a Pokemon Doctor, Dawn is staying in Sinnoh to become a part-time Pokestylist, and Ash is going to Isshu to go back to dream of Pokemon Master. Ash and Brock wave goodbye to Dawn and Piplup as they take a ship home to Kanto. When reaching the familiar crossroad, Ash and Brock shake hands one last time, and split up: Brock goes back to Pewter City, and Ash goes home to Pallet Town to prepare for the journey to Isshu.
