Goh

Goh is a thin young boy that has a youthful appearance. He has messy vulcan-colored hair with two red highlights, slightly tan skin, and blue eyes. His outfit consists of a red and grey short-sleeved hoodie with a PokéBall design, black sweatpants, red socks, and a pair of grey and black shoes.

During the Darkest Day arc, Goh receives a Dynamax Band, which he wears on his right wrist.

He has a pair of black swim trunks, similar to what Ash wore in Alola, with red stripes instead of white.

In "To Train, or Not to Train!", Goh dons the male uniform of his school which consists of a blue and white shirt with a yellow tie, a white pair of shorts with a dark blue anchor motif on both sides.

When working at Laxton's farm in "How Are You Gonna Keep 'Em Off of the Farm?", Goh wore a red jacket with gray accents, grey gloves, black pants, black boots and a light gray cap.

Goh's personality contrasts much with Ash's, starting with their objectives: while Ash loves battles and seeks to be a Pokémon Master, Goh loves to capture, in particularly care for his Pokémon more intently and at a more mature and emotional level than Ash, and seeks to complete the Pokédex.

Goh is a stylish, cool-headed boy with a confident demeanor and a hot competitive streak. Compared with Ash, who is a reckless and headstrong boy from a small town, Goh is an intelligent city boy and regularly makes use of technology. Goh is also highly knowledgeable about Pokémon especially as a child, being fairly adept at information-gathering and analyzing, both of which were useful in gathering clues. However, this also made him have somewhat of an ego, and at times act like a know-it-all, which, according to Chloe, causes him to have difficulty making friends. This trait appears when he becomes upset that his argument with Ash almost ruined their friendship.

While Goh clearly loves Pokémon and gets excited about meeting them much like Ash does. At first, Goh was shy about raising his Pokémon, due to his somewhat awkward demeanor. However, overtime, Goh formed very close bonds with his Pokémon, especially Cinderace, Inteleon and Grookey. Additionally, despite Goh's confident demeanor, he is apparently very easy to fluster and embarrass, as he blushes often. Despite his deep knowledge of Pokémon, Goh is still new and inexperienced when it comes to being a Trainer. Unlike most Trainers who capture new Pokémon via weakening them through battle, Goh instead simply tosses Poké Balls at every Pokémon he encounters without battling them at all. However, Goh overtime does realize he needs to battle Pokémon if they refused to be caught right away. One time, he wanted to catch a member of the Dratini evolutionary line but was unable to do so since he had earlier wasted all of his Poké Balls trying to catch a Dewgong. Because of his desire to catch every single Pokémon, there is, Goh sometimes becomes discouraged, either whenever someone catches a Pokémon that he wanted to catch, or if the Pokémon turns out to already belong to someone else. For example, he tried to capture a Mightyena without realizing that it was Hodge's, and had hoped to catch the Gengar that had been haunting the Cerise Laboratory, despite the fact that it had already formed a bond with Ash and had decided it wanted to be his Pokémon instead.

His battling style also showcases his inexperience during his participation in the Battle Frontier Flute Cup, where his by-the-book approach of relying solely on type advantages and raising attack power leaves him defenseless against more experienced Trainers. This is another trait that sets him apart from Ash, who often uses unorthodox methods and his gut instincts to win battles. In "Making Battles in the Sand!", he utilized some of Ash's unpredictable tactics against a wild Flygon such as using Draco Meteor as a form of Raboot's Ember attack.

Goh also appears to be against the idea of actually training his Pokémon in order to improve their abilities, as shown when his Cinderace, as Scorbunny wanted to learn Ember, but Goh believed that its move-set of Quick Attack and Double Kick was already enough and that it didn't need to learn other moves, though this was mostly out of concern for it pushing itself too hard. This caused him and Scorbunny to get into a disagreement and putting a bit of a strain on their friendship. However, Goh improved on training his Pokémon as he realized that he needs to make sure his Pokémon were in battling shape in case he needs to battle.

Due to the fact that he spent most of his childhood focusing only on researching along with capturing Mew and not wanting any other friends besides Chloe, Goh seems to have a lack of social skills, leading to him not understanding the feelings of other people and Pokémon. He mistakens some playful banter from Hodge for insults, believed that his friendship with Ash was over after a brief argument between them, and his concern over Cinderace, as a Scorbunny, hurting itself while trying to learn a new move caused the Rabbit Pokémon to become upset with him and believe that he didn't want it to become stronger. Even though he means well, he is ignorant of how his words may affect others, such as his Cinderace, as Raboot, and the underlying problems that may perpetuate the strain in his friendship with his partner. However, he gradually learns to socialize and understand other's feelings better as time goes on. Also, Goh begins to be more open about making new friends.

Goh is very intelligent, though he often skips school and doesn't like doing homework. He is a skilled researcher and uses his Rotom Phone to help him gain new info. Much like Brock, Tracey Sketchit, Max, Cilan and Clemont before him, Goh has great knowledge about Pokémon.

While Goh can run reasonably well, he does struggle in climbing and other athletic skills such as swimming.
