Ash is incredibly selfless, he will often go to extraordinary lengths to earn a Pokémon's trust and respect and to better understand a Pokémon that he sees as troubled. He is also very fair-minded and trusting, a true testament to his good-natured character.
Ash has a strong sense of justice, especially when it comes to Pokémon. If a Pokémon is in trouble, he will make every effort to help them, even if he has no prior connection to them. If they are the cause of trouble, he will stop them, and then try to understand them, with almost all such occasions being a case of the Pokémon, or their Trainers or friends, having a problem which can't be resolved normally. In those cases, he will selflessly volunteer to help them. Should the problem be caused by humans, such as Team Rocket, Pokémon thieves, hunters, or poachers, Ash will resolve to do anything in his power to stop them.
Never straying from his goal, Ash has remained loyal to his friends, family, and supporters, but most of all his Pokémon. Ash became a great Trainer by learning to find and use the inner strength of each of his Pokémon by bonding with them. He also learns where their hidden abilities lie, as well as resorting to unorthodox strategies when fighting particularly challenging opponents. He is happy when his Pokémon evolve but lets them choose whether or not they want to evolve instead of forcing them.
Physically, Ash is in very good shape, especially for someone 10 years of age. He has a lot of stamina, walking miles upon miles through all kinds of environments, while journeying between towns on his journey. He also has huge endurance, as seen when he took powerful attacks from various Pokémon head-on and then recovering quite quickly. Furthermore, Ash has demonstrated himself to be a bit acrobatic. Ash has occasionally displayed great reflexes, being able to dodge attacks or catch falling objects out of the blue, and even being able to save himself, or others, in the last second during perilous situations. What's more, Ash has exhibited tremendous will power, as seen when he took attacks for long periods and keeps advancing. He is also strong, being capable of picking up heavy Pokémon such as Larvitar and Hippopotas.
Ash possesses some special abilities as he has the rare ability to use Aura. He is said to have the same Aura as Sir Aaron, a legendary hero, and is able to manipulate it in the same way. Therefore, he made a connection with Sir Aaron's Lucario.
During his journey through Alola and the one-year timeskip that followed, he matured significantly and took part in events that involved criminal organizations more seriously. He also learned how to cook from his mother and learned many things from Professor Oak such as Pokémon's abilities, typings, and how to train and care for them. Like his anime counterpart, he will get angry if someone hurts someone close to him, especially if his younger siblings, Silver and Leaf, get involved. He also got more wiser and smarter to the point he can analyze a battle to finish it rather quickly, but also maintained his unexpected battle styles. In most situations he is still quite reckless, but he also makes sure to not cause severe damage to his surroundings or to others near him. He is also known to meditate with his Pokémon in order to give them more patience and calm them down in dire situations and his meditation went to another level when he captured his Riolu that later evolved into a Lucario. He also trained his body and trained in the art of stealth in order to defeat criminal organizations. With his trained body, he can maintain his balance so he can perform moves like somersaults and flips with ease without losing his balance or making a sound.
Prior to Series
As a Trainer, Ash has caught and befriended a sizable number of Pokémon throughout the book. His philosophy on training is that Pokémon are individuals and that a combination of trust, friendship, and hard work are needed to overcome adversity. Several of Ash's Pokémon were caught because they allowed him to after he befriended them. He is willing to work with any Pokémon that comes into his care. Ash has stated that he believes in quality over quantity.
Ash's battle style is generally spontaneous and fairly unorthodox (Being able to easily fight under type disadvantages), and his Pokémon often reflect these traits. He has been shown to use unusual strategies. Ash stated that his unique strategy is the one he can truly count on, instead of simply mimicking others.
Ash is very attached to his Pokémon and prefers to battle and train with them personally. Furthermore, he cares about their opinion, even giving them the option of whether they should evolve or not. However, if it is by their wish, or if he believes it is best for them, Ash will reluctantly trade or release them, and in some cases, leave them with more experienced individuals so that they could get stronger. He has done this for Primeape and Lapras. He has left them with a more experienced individual or released them respectively.
Ash currently has ownership of 76 Pokémon, including all 30 of his Tauros. Including pre-evolved forms, traded, released, and given away Pokémon (and not including the additional Tauros), in total, Ash has currently officially owned a total of 96 different Pokémon species.
Aipom met Ash on a mountain where she worshiped a Giant Slaking and where she stole Ash's hat. Near to the finals of the Grand Festival, Ash decided to battle Aipom and finally caught her. Aipom has shown a great drift for Contests and was soon traded to Dawn for her Contests, and a few episodes later Aipom evolved into Ambipom.
Tauros (x5) ♂
Ash returned to the Kanto Safari Zone to try his luck on some new Pokémon he could catch, however Tauros kept getting in his way once again making him stop at 5 before leaving. He set up a Wonder Trade System for these specific Tauros due to not wanting to trade any of the 30 Tauros at his lab because of the bond he has with them and the bond they have with each other. During a trading festival, Ash traded one of the 5 Tauros for a Rhydon.
Beedrill was a Pokémon Ash caught in the Bug-Catching Contest and later chose to give Beedrill to Casey because of her love for yellow and black-striped Pokémon.
Beedrill's only known move is Twineedle.
The Bug Stops Here
Ash befriended this Haunter when he visited the Pokémon Tower and returned to Saffron City with him. Haunter disappeared when Ash challenged Sabrina again. When Sabrina's Kadabra was about to defeat Pikachu again, Haunter appeared and made Sabrina laugh, which unlocked her heart, making her return to her old self. Ash was given the Marsh Badge and he left Haunter with Sabrina to keep her under control.
