Dynasty Warriors Storyline
Ash, Pikachu, and the rest of the pals are watching over a beautiful night. Suddenly, the four meteorite rocks have landed on the planet Earth. He, his pals, and the Symphogear Heroines are trying to look for them. After having a successful search, they met Kamen Rider Kabuto and the rest of Ten Legendary Warriors-United Heroes.
Ash is a really energetic, optomistic kid.
Pikachu has been with Ash since he began his life as a Pokemon trainer, and is a VERY close friend to Ash.
Misty joined Ash in Pokémon Emergency!, traveling with him because she wanted him to replace her bike, which was destroyed by his Pikachu. She would continuously travel with him until Gotta Catch Ya Later!, when she returned to Cerulean City nearly full-time to lead her family's Gym, though she briefly traveled to Hoenn and met up with Ash's Advanced Generation group in The Princess and the Togepi and A Togepi Mirage!, and again from The Scheme Team until A Real Cleffa-Hanger to "escort" her back home. She met up with her friends one more time.
Brock first joined Ash in Showdown in Pewter City after Ash battled him in the Pewter City Gym. After his father Flint offered to take over the duties of Gym Leader, Brock followed Ash through Kanto, leaving briefly from Poké Ball Peril to A Tent Situation to work for Professor Ivy. In The Rivalry Revival, Brock returned to be with Ash and Misty until Gotta Catch Ya Later!, though he, unlike Misty, would return shortly, in You Can Never Taillow, sticking with Ash until Home is Where the Start is!. He would again return in Two Degrees of Separation!, and so traveled through Sinnoh with Ash until Memories are Made of Bliss!.
Gary Oak is a recurring character in the Pokémon anime. He is a Pokémon Researcher from Pallet Town and grandson of Professor Oak. He is a childhood friend and former rival of Ash Ketchum. His Japanese name is derived from Shigeru Miyamoto.
Ash may have traveled to Hoenn alone; however, shortly after his arrival, he met May, a young girl who desired to travel around the world and a fellow Trainer who was just starting her journey, and then ended up destroying her bike just like that of Misty. Though she initially did not care for Pokémon, she eventually found Pokémon Contests, in which she competed while in Hoenn and then later in Kanto. May traveled with Ash through the entire Advanced Generation saga, from Get the Show on the Road to Home is Where the Start Is!, after which she went off to Johto to compete in Contests there. She, like Misty, reappeared briefly during the Diamond & Pearl series to compete in the Wallace Cup from A Full Course Tag Battle! until Strategy with a Smile!.
Max is May's younger brother. He does not have any Pokémon of his own because he is too young, but he often befriends certain Pokémon. He traveled with the group from There's no Place Like Hoenn until Home is Where the Start Is, when he went home to Petalburg City. However, he made a promise to Ash that as soon as he got his own Pokémon, he would battle Ash.
Like his journey into Hoenn, Ash ventured to Sinnoh alone, where, in When Pokémon Worlds Collide!, he would meet Dawn. From that point, after saving Ash's Pikachu and having her bike fried in a similar way to May's and Misty's, Dawn would travel with Ash and Brock through Sinnoh, which she did until Memories are Made of Bliss! when all three friends split up.
Dawn rejoins Ash's group in the Best Wishes series in Piplup, Pansage, and a Meeting of the Times! to compete in the Pokémon World Tournament Junior Cup. Dawn would leave the group in Goodbye, Junior Cup - Hello Adventure! and travel to Johto to compete in the Wallace Cup.
Paul is a recurring character in the Pokémon anime. He is a Pokémon Trainer from Veilstone City who was first seen at the end of Two Degrees of Separation!, though his full introduction was in When Pokémon Worlds Collide!. He is Ash's main Diamond & Pearl series rival.
Iris is said to be a wild girl, as proven by the fact that she swings on vines. She decided to travel throughout Unova and the Decolore Islands with Ash from Enter Iris and Axew! until Best Wishes Until We Meet Again!.
Cilan, a Pokémon Connoisseur and one of the Gym Leaders of the Striaton City Gym, travels with Ash and Iris in their journey through Unova and the Decolore Islands from Dreams by the Yard Full! until Best Wishes Until We Meet Again!.
Trip was Ash's only unfriendly rival in the Best Wishes series. The rivalry formed when Trip found out that Ash was from Kanto, a region Trip thinks very little of. Trip believed Ash to be a redneck from the boonies who needed to go back to the basics of Pokémon, causing a heated rivalry. However, they were shown to respect each other to some extent in various episodes. Like with Gary and Paul, the two became friends when Ash beat Trip at the Vertress Conference.
The Team Rocket trio, sometimes abbreviated as TRio or JJM, is a trio of members of Team Rocket, consisting of Jessie, James, and Meowth.
Serena is a beginning Pokémon Trainer from Kalos. She is a fashionable girl who met Ash once before when they were younger. While the daughter of a famous Rhyhorn racer, Serena eventually sets her goal to be a famous Pokémon Performer. She started traveling with Ash in Giving Chase at the Rhyhorn Race! until Till We Compete Again! where she traveled to the Hoenn Region to participate in Pokémon Contests in order to further her skills as a Performer.
Clemont is an inventor Ash met after being ejected out of the Lumiose City Gym. His backpack, called the "Clemontic Gear", carries a variety of inventions and gadgets. He traveled with Ash from A Battle of Aerial Mobility! until The Future Is Now, Thanks to Determination!, then rejoined the group in The Moment of Lumiose Truth!, he decided to stay in Lumiose City in Till We Compete Again! when Ash returned to Kanto.
Bonnie is Clemont's little sister. She is a young and cheerful girl, who despite being too young to officially train Pokémon, holds a great interest in them. She is proud of her big brother's accomplishments, but is not above criticizing him. She started traveling with Ash in A Battle of Aerial Mobility! and stayed in Lumiose City with her brother when the group went their separate ways in Till We Compete Again!.
Lillie is one of Ash's classmates. She is terrified of physically interacting with Pokémon, and tends to freeze up whenever one Pokémon enters her personal space. She was the second of Ash's classmates he would meet. She was watching a Tauros race between Lana, Mallow and Sophocles as Ash accidentally stumbled upon the racing track and spotted Lillie on the other side. They became classmates when Ash enrolled himself at the Pokémon School shortly thereafter.
Mallow is one of Ash's classmates. She is talented cook for both people and Pokémon, and is a self-proclaimed poster girl at her family's restaurant. She met Ash while she was having a Tauros race against Lana and Sophocles and they ran him over when he accidentally stumbled upon the track. They became classmates when Ash enrolled himself at the Pokémon School shortly thereafter.
Lana is one of Ash's classmates. She enjoys many seafaring activities such as fishing while riding on Lapras. She was the first of Ash's classmates in the Sun & Moon series series to meet Ash when she accidentally fished him up while he was riding on a Sharpedo. They would later meet again at the Pokémon School and become classmates when Ash enrolled himself.
Sophocles is one of Ash's classmates. He enjoys inventing helpful devices and machinery. He met Ash while he was having a Tauros race against Lana and Mallow and they ran him over when he accidentally stumbled upon the track. They became classmates when Ash enrolled himself at the Pokémon School shortly thereafter.
Kiawe is one of Ash's classmates. He is very gruff compared to his classmates and makes deliveries between islands on his Charizard. Ash first spotted Kiawe flying on his Charizard when he was lost in a forest. They formally met while Kiawe was in a battle with Team Skull and Ash joined in, making Kiawe the last of Ash's classmates Ash would meet.
As a Trainer, Ash has caught and befriended a sizable number of Pokémon over the course of the anime. His philosophy on training is that Pokémon are individuals and that a combination of trust, friendship and hard work are needed to overcome adversity. In fact, several of Ash's Pokémon were caught because they allowed him to, after he befriended them. He seems to battle best with Pokémon that are similar to Pikachu: ones that are speedy and maneuverable, yet able to perform high-powered attacks; however, he is willing to work with any Pokémon that comes into his care.
Ash's battle style is generally spontaneous and fairly unorthodox, and his Pokémon often reflect these traits. He has been shown to use unusual strategies. For instance, during the Diamond & Pearl series, he incorporated a twisting-spinning type maneuver in his Pokémon's offensive and defensive techniques, which eventually lead to him creating the original technique, Counter Shield. Also, sometimes he would use someone else's battle strategies as shown with Paul and Tierno, though when using the latter, Ash stated that his own unique strategy is the one he can truly count on, instead of simply mimicking others.
