Accidental Pervert: Decides when he visits a hot springs to either get his pokemon or help others spy on women to find their hygiene secrets.
All-Loving Hero: Ash is the closest thing this World Half Full really has to a saviour, who can bring people together and solve conflicts in the most non-violent manners possible.
Annoying Younger Sibling: Brock and Misty sometimes view him as this. That said, while they're correct about much of his naivety and brashness, they're not aware of his backstory and so don't realise just how well he actually can handle himself in light of everything.
Big Eater: Averted, as Ash grew up not always having food available and having to conserve food.
Book Worm: He became one to make up for his limited education. Poison Lance encourages this and only let Ash attend school unti he was fluent at writing and reading. He reads a lot, from every posible subject.
Chekhov's Classroom: One chapter begins with Ash reading a book on how lighting is formed. When Ash and Pikachu are fighting a flock of crazed spearow, Ash uses this information to teach Pikachu how to form Lighting Bolt.
Guile Hero: Is the least physically competent of the team, so he mostly relies on tactics and thinking his way out.
Hulk Speak: He used to speak like this as a child, and only got that due to Poison Lance making sure that he had regular contact with humans. Even now that he got better, he still has a limited vocabulary.
Innocent Inaccurate: When he first heard of Pokémon training, he was horrified at the concept of taking wild Pokémon from their habitat, stuffing them into little Poké Balls, and forcing them to fight. He had to be reassured by Poison Lance that most Pokémon go in knowing the risk, and some actually go in wanting to be captured to get stronger.
Another example is that he doesn't understand why people want to peek on women in the baths and deduces that men want to find out women's hygiene secrets.
Innocently Insensitive: Sometimes his lack of tact can make him accidentally insulting, as such as the Porta Vista chapter as he calls Misty ugly.
Also, he's unaware that Charmander is growing resentful of him for not allowing him to see combat.
Innocent Prodigy: Is a genius at tactics and Pokémon training, but is very naive about human social mores.
Magnetic Hero: Most of his Pokémon chose to join him, rather than him capturing them.
Meaningful Rename: When Ash rejoins human civilization, he goes under the name Aaron Autumns. Might also be a reference to SirAaron, an Aura Guardian.
Mundane Luxury: Sleeping in beds, having a roof over his head, or feeling full or having an open fire are unique experiences.
Why Did It Have to Be Bird Pokemon: Getting attacked and nearly getting killed by wild Spearow, she initially develops a fear of bird Pokémon. Although she desensitizes herself by grooming Ash's Pidgeotto.
Big Brother Mentor: He teaches Ash how to fight and survive since Ash keeps getting in trouble.
Wouldn't Hit a Girl: Averted when he fights the Rocket Grunts during the Hidden Village Arc. Brock is specifically described as killing a few female grunts with no less hesitation than the males. Along with basically being trained for it, he knows full well that these people are no less criminals and can't be shown mercy.
Completely Unnecessary Translator: Justified as Ash is trying to preserve the image that he doesn't understand Pokémon, but exploits his close bond with Pikachu by saying he can understand Pokémon through Pikachu. It doesn't always work, and Pikachu hates that they have to play charades.
Deadpan Snarker: Constantly pokes fun at Ash's ignorance of human social mores and other trainers' misunderstanding of him.
A Pidgeotto from Fuchsia City who went to Pallet Town to visit some old friends, until she tried to eat Ash's Caterpie. Getting caught was a win-win situation for her, since getting captured meant she gets to travel to faraway lands.
Carnivore Confusion: Averted, she eats wild Pokémon without any worries. She was introduced hoping to eat Caterpie and met Magikarp by eating one of his daughters.
Easily Forgiven: Forgiven for trying to eat Caterpie and forgiven by Magikarp for eating his daughter.
There Are Two Kinds of People in the World: Humans come in two flavors in his opinion: the first is people like Team Rocket who use and abuse other people and Pokémon. The second are people like Melanie and Ash who are good people who treat others well and try to help others...and often get used, abused, and killed by the former group. This opinion was formed due to Bulbasaur living in Orre and having had to deal with the kinds of people who live there.
Thou Shall Not Kill: Averted. It's shown onscreen that he kills several Team Rocket grunts that were planning to attack the Pokémon Village, and shows no remorse for it.
The Load: He thinks Ash views him as this since he doesn't allow Charmander to battle for tactical reasons, which could be foreshadowing his future rebellion with Ash when he evolves.
The Resenter: While he does appreciate Ash's rescue of him and Ash's commitment to him, he hates that Ash does not let him see battle and thinks he's being held back because he isn't strong enough. He grows more and more resentful the more Ash doesn't allow him to fight.
Establishing Character Moment: As described by Ash, he walked up to the group, looked at Misty, decided that "she could use some help", and subsequently grabbed a Pokeball to be sucked into. Ash notes it's the first time he's heard of a Pokémon capturing themselves.
Magikarp ([[spoiler He Who Tastes Like Shit]]/?????)
A Magikarp found faking being wounded on the beach.
Training from Hell: Received this from Lorelei of the Elite Four. Which is why Misty is a big fan of Lorelei.
The Unfought: Ash never battles them, and like the anime, they give him a badge. This is more due to their gratitude for Ash saving Misty. Although it is implied that unlike in the anime, they're much stronger and would probably have beaten Ash.
The Unfought: Justified - had he used his main Raichu, Ash wouldn't have stood a chance. He was still pretty impressed by Ash and Pikachu for defeating the weaker Raichu though, since it wasn't a pushover either.
Super Speed: Is faster than Pikachu, who's no slowpoke himself.
The Unfought: Instead of using her in the Gym Match against Ash, Surge used one that he'd captured more recently. Which is a good thing, since she's a lot stronger than the Raichu he used in the gym battle.
Break the Cutie: Sabrina was mindraped by Team Rocket, forced to kill her gym members and loved ones, and nearly destroyed Saffron City before being freed.
Brainwashed and Crazy: She was forced by Team Rocket to kill her own gym and take over Saffron for them. Fortunately, Ash managed to break her free, removing the need for Agatha to Mercy Kill her.
World's Strongest Psychic: Recognised as this, as well as a potent trainer in her own right. Such that Agatha was hoping for Sabrina to be her successor one day. This is not the case anymore - even with Ash destroying the machine amplifying Hikaru's psychic powers, Sabrina needed to fry a number of her brain cells to end his control over her. This has reduced her physical capacity and also crippled her psychic powers to a mere third of their usual potency.
Baleful Polymorph: She is last seen (before her death) being turned into a porcelain doll by Sabrina, with it travelling up her body. Nothing Is Scarier, too, because it's unclear if it was at all real, her imagination, or some unholy combination of both... But her head still bled from the neck down when we saw it; Sabrina mentions going to visit her grave in Cerulean City; and Captain Torch's account of the incident indicates that much of the Cold-Blooded Torture Sabrina did was psychological... so perhaps it was simply elaborate Mind Rape. No less horrifying, however.
Father, I Don't Want To Fight: Aya doesn't want to be a trainer. While she does like her Venonat, she prefers fighting on her own and doesn't really like Pokémon. Which is a problem since her father Koga is being scouted for the Elite Four and her older sister is her father's successor.
Bad Is Good And Good Is Bad: The core of Jessie and James's moral compass, to point of getting offended at called "Good Guys", and are in Team Rocket in order to fight against them. They basically think Team Rocket is benevolent purely because they oppose the League.
Exemplified by that they think the "Good Guys" do terrible things and the "Bad Guys" are the ones that help people.
Bunny-Ears Lawyer: Jessie and James are still very goofy and sympathetic, but are extremely dangerous. Their competence and danger level is so high they can openly get away with failing to catch Pokémon and their flaunting of Team Rocket's anti-attachment clause because they are so skilled. Noted by Misty when Jessie came into the perfect position to snap her neck and instead chose to graffiti Misty's face with marker.
Stealth Mentor: They fight Aaron in hopes of either recruiting him, capturing him, or making him stronger.
Supreme Chef/Team Chef: In a subversion of canon where she's a Lethal Chef, Jessie is apparently one as she does all the cooking and makes all the snacks. Misty, thinking her cooking was from a catering service, thought Jessie did very good work.
Locked Out of the Loop: Poison Lance made sure he wouldn't know Ash was still alive, because they feared it would get him sent to an orphanage and make him a target for the group that killed his parents.
Axe Crazy: He and his friends were planning to kill Ash and everyone else in the Pokémon Center.
Freudian Excuse: His father was an abusive drunkard that murdered his beloved mother and forced Damian to hide the body. Averted, as it shows how he became the person he is, but the narrative does not let it excuse his actions.
Didn't Think This Through: Were holding the hypnotized missing children captive to protect them from getting caught by more dangerous thugs, without thinking of any way to contact or attract the attention of the authorities. To be fair, long-term planning is not natural to wild Pokémon.
The Kindnapper: The missing children were hypnotized into thinking they were Pokémon so the Venomoth knocked them out with Sleep Powder to prevent them from getting hurt.
