Ash Ketchum (サトシ):

Appearance - Ash is a skinny, slender teen with black hair, slightly tan skin, and brown eyes with two distinctive lightning bolt-like markings for cheeks underneath each eye. Ash's pupils were not visible during the Indigo League and through the Diamond & Pearl series until the Best Wishes series made them more profound and distinguishable.

While Ash wears a few different outfits, he always wears a baseball cap, which changes depending on the region he is in. Without a cap, Ash is shown to have a cowlick and a narrow, triangular, and edgy tuft of hair in the middle of his forehead that comes to a point on the right side. Ash wore a loose short-sleeved shirt with white and blue stripes, brown capris pants with red outlines, baggy pockets and red folded sleeves at the edge, and blue sneakers. His cap was red, dark blue, and gray, and the Poké Ball design was white. Ash also kept a silver Z-Ring on his left wrist, which was later upgraded into a black Z-Power Ring. Unlike in previous regions, Ash did not wear fingerless gloves while he was in Alola. As a member of the Ultra Guardians, Ash wears an indigo and white uniform with light periwinkle accents as the edge of the short sleeves, collar and inlines of his uniform are black. He wears matching indigo gloves.

Personality - Ash is very determined to be a great Pokémon Trainer. Personality-wise, Ash is a strong person, shows confidence when battling and shows a lot of sympathy towards Pokémon, usually helping and befriending them through his long journey. As a result, Ash doesn't like Trainers who mistreat Pokémon, such as Damian, Paul, and Shamus. Ash also serves as a role model for many people such as May, Dawn, N, Serena, Sawyer, Lillie, and Goh. In fact, he often astounds people with his skills and abilities, and unpredictability. Ash's strategy and tactics in battle are usually problem-solving, including thinking on his feet during special matches or that relate to the special and unique abilities of Pokémon. Also, Ash even takes input from his friends and has always helped him whenever he was stuck in a jam. Ash is generally kind, brave, enthusiastic, compassionate, passionate, adventurous, selfless, fair-minded, trusting and good-natured. However, he can be stubborn, hot-headed, short-tempered, impatient, cocky, reckless, and sometimes impulsive at times. During his journey, Ash realized that some of those traits were affecting him, as they had caused him to lose some of his gym battles. By recognizing this, Ash trained himself for his rematches and keeping those parts of himself in check so they would not only affect him in battle again, but also outside of it as well. Although those traits still remain, they have been shown to be less of a problem during his Pokémon battles. Thanks to his hard work, Ash has corrected the hot-headed, cocky, and impulsive parts of his personality, though he still shows them if Pokémon were being mistreated, some of his friends teasing him, and various other reasons. Since then, Ash has demonstrated much greater maturity and level-headedness both in and out of battles. In addition, he has given everyone around him good advice to better themselves and their goals. Ash also has a fascination with science and technology, even though he cannot understand most of it.

When she is traveling with the player character, she is usually exclaiming to do some shopping of her own, and in cities would tell the player character that she got lost and ended up buying outfits in a shop. Lillie is always getting lost, and the player character has to help her. This happens usually because Lillie is trying to avoid Team Skull grunts, as she is not a trainer, and ended up going in the wrong directions trying to get away from them.

To complete the outfit, he wears a red flame designed wrestling mask with green and light blue coloring with blue designs at the back of his mask. Later, he wears a Z-Ring on his left arm.

Personality - Most of the time, Kukui is a helpful and friendly person. He often helps them throughout their adventure; however, he seems to be silly or out of his mind sometimes, such as when he takes attacks from a Rockruff in the beginning of the game. He has a "secret" identity where he is known as the "Masked Royal," a pro wrestler. However, when confronted, he always tries to deny it.

Lana (スイレン):

Appearance - Lana is a short and slender young girl with fair skin, blue eyes, and short blue hair, the latter in which she wears a yellow string headband that resembles a fishing net.

Personality - Lusamine was originally shown to be a kindhearted lady who is willing to "create a utopia for Pokémon". In truth, however, she seeks for beautiful things she could "own". Though her daughter and son both try to warn her about the dangers, Lusamine does not forgive them for betraying her, showing utter coldness, as she does not want anything to stand in her way to obtain the power from the Ultra Beasts. Ultimately, she wishes to live in a world that consists only of her and Nihilego, which she views as a surrogate family that is completely obedient to her. She is also extremely manipulative, taking advantage of Guzma's inferiority complex to befriend him and convince him to serve as a hidden mercenary for the Aether Foundation. Despite this, it is implied that Lusamine was a genuinely kind person at one time, but, after her husband Mohn was lost in the Ultra Beast's world, grief drove her insane. After her defeat and forceful separation from her Nihilego, she seems to regain some of her sanity and comments that she finds Lillie "beautiful" before collapsing into a coma.

Although he appears to have a tough exterior, it is eventually revealed that he is actually quite caring and always thinks of the well-being of Pokémon, and he cares about his sister Lillie deeply as well. He also cares for his Pokémon Type: Null, whom he rescued from the Aether Foundation and sought to free it from its metal restraint.

A female will have a V-shaped notch at the end of its tail, which looks like the top of a heart. He is classified as a quadruped, but he has been known to stand and walk on his hind legs.

Personality - Pikachu is very ambitious, because he hates being defeated. At the beginning of the series, he was easily aggravated and hesitant to warm up to Ash. Whenever Ash was not around, Pikachu took a leadership position for the team. He was curious, friendly, intelligent and had shared Ash's fondness for battling. Pikachu was a very determined Pokémon and unwilling to give up in tough situations. He is also sensitive because he understood Piplup’s dealings and cried.

Rotom Dex:

Appearance

• The Rotom Dex is a small and red robot-like device. It mainly takes on the flat and square shape resembling that of a smart tablet. Rotom's head fans out on the top, rounding out to a half circle with two points on the side. These side contain two holes on each side resembling speakers. A large red antenna comes from the middle of device's head, this point is triangular in shape and matches with other the Rotom species' anatomy, this point does not appear unless a Rotom is present inside the machine. On the front of the tablet is the screen. When a Rotom is not powering the device, the screen is all gray, with two ovular shapes on the upper half. A black rounded semi-circle appears between the two ovals. When a Rotom is powering the device, the square screen is mostly white and light blue, with the ovular spots now being filled in with Rotom's eyes. In this form, Rotom's eyes are similar to how they appear outside the device, white ovals with blue pupils and a line going through them horizontally. Like the species, Rotom's pupils are where its eyelids are placed, being colored all white when close. Rotom's small mouth appears on the screen below and the mouth can appear and disappear. When smiling, its mouth takes on a crescent shape with three teeth showing.
• Rotom can control the feet and arms of the device that fold in and out. Its feet are small and around and sit on the bottom of the device. While Rotom typically prefers to float while inside the Pokédex, the feet can be used to stand on objects. The device's arms can act as actual hands for Rotom. They are smaller towards the body and get bigger going outwards, taking on a lighting bolt shape. The large flatter ends of each "hand" has two rounding protrusions on both the front and back ends, with the front of the left one having a gray spot. Rotom Dex can retract its arms and legs back into the device's body and start emitting a light blue electric glow around its body, similar to other Rotom and Rotom-powered devices.

Personality

• Rotom claims to be a self-learning Pokédex (similar to an A.I.) and has the ability to speak human language. Early in the series, it has a bad habit of getting up close and personal to the Pokémon in order to see if the information about it is true, only to annoy and get attacked by said Pokémon. It also updates itself whenever it meets a new Pokémon by taking pictures of it or when it finds something new about a Pokémon. As shown in Rising from the Ruins!, once Rotom Dex updates its photographic database and finds a way to describe the new Pokémon, the updated information then becomes available to download on various other Pokédexes. Rotom gets along with Ash and all of his friends, but has shown an aversion to Sophocles's attempts to "study" it. Largely due its self-learning nature, it also has an innate desire to catalog any Pokémon within the region. In Alola, Kanto!, it left during a field trip to Kanto on its own to try and catalog all 151 Kanto Pokémon, only missing one, Mew, by the time it returned to Oak's Lab.
• While inhabiting the Pokédex, Rotom does not appear to have combat functions, and is unable to use any moves. As shown in Crystal-Clear Sleuthing!, it can use its "arms" to extract data from other electronic devices and update itself with the device's function. Additionally, if it is upside down or sideways, it can recalibrate its screen to show the data the right side up. Rotom also uses the numbers on its screen to express the statistics, usually showing the percentage of something, for example, to show the likelihood of a Pokémon appearing nearby. As shown in Let Sleeping Pokémon Lie!, Rotom has a clear waterproof casing, allowing it to be used underwater.
• Rotom is also a huge fan of the show Alolan Detective Laki. It likes to cosplay as the titular character Laki, wearing a wig modeled after his hairstyle of Laki, which Professor Kukui bought for it, to achieve this. It also looks up to Laki and even used his thought process in order to figure out how to deal with the fact that it had become frozen. However, Rotom tends to jump to conclusions with its deductions, such as in Crystal-Clear Sleuthing!, when it believed that Kiawe stole Ash's Electrium Z. This was also shown in Lulled to La-La Land!, when it accused Lillie of putting Ash and the rest of the group to sleep and draining their energy, causing Mallow to jump to her defense. In addition, it is known to state the obvious through its calculations. Rotom is prideful in expressing the information it helps to deliver. So much so that in Bright Lights, Big Changes!, it was revealed to have realized its goal of becoming the universe's greatest Pokédex.
• In The Dex Can't Help It!, it is revealed that if Rotom takes too much of a shock, it will be forced out of the electronic it is inhabiting. As mentioned in the episode's Poké Problem segment, Rotom has spent so much time in its Pokédex form that it feels uncomfortable outside of it.
