Description
Goh is a ten-year-old Pokémon Trainer and research assistant originating from Vermilion City in the Kanto region. His defining ambition is to encounter and capture every Pokémon across all regions, a goal sparked by witnessing the Mythical Pokémon Mew during a childhood summer camp at Professor Oak's laboratory alongside his friend Chloe. This pivotal experience cemented his decision to become a Trainer.

Growing up, Goh possessed extensive Pokémon knowledge but struggled socially, leading to periods of isolation exacerbated by his parents' frequent work absences, though he remained proud of their careers. A significant childhood event involved befriending Horace during a family trip to Azalea Town while searching for Celebi. Horace's failure to meet him the next day left Goh feeling betrayed, deepening his reluctance to form new human friendships beyond Chloe until later events.

Serving as a research fellow at Cerise Laboratory, Goh travels extensively and partners with Ash Ketchum. Their collaboration begins after jointly encountering Lugia in Vermilion City, an event inspiring Goh to accept Ash as his first close friend besides Chloe. Professionally, he aids Professor Cerise in investigating Pokémon phenomena, utilizing a Rotom Phone for data and fieldwork. His method for completing the Pokédex prioritizes direct capture, frequently throwing Poké Balls immediately upon encountering wild Pokémon. This approach evolves over time; he gradually incorporates strategic battles to weaken aggressive targets or overcome capture resistance.

Personality-wise, Goh contrasts with Ash through his analytical, technology-reliant, and initially reserved nature. He exhibits confidence but can be competitive and easily flustered. Early on, he shows reluctance to train his Pokémon for battle, believing innate abilities sufficient—a viewpoint straining his bond with Scorbunny when he discourages its efforts to learn Ember. Prompted by this and other challenges, he gradually grows in understanding Pokémon emotions and needs. His social skills improve through interactions with Ash, Chloe, and others, helping him overcome earlier egocentric tendencies and value teamwork.

During "The Arceus Chronicles," Goh investigates disturbances in Sinnoh with Ash, Dawn, and Brock. He wears historical Sinnoh attire and participates in catching starter Pokémon—Cyndaquil, Oshawott, and Rowlet—using replica ancient Poké Balls. His analytical skills aid the group in identifying interdimensional disruptions caused by Team Galactic and a berserk Heatran. Meeting Brock for the first time, he expresses admiration for Brock's expertise as a former Gym Leader and Pokémon Doctor. Goh coordinates with Legendary Pokémon like the lake guardians Azelf, Uxie, and Mesprit, and Arceus to resolve the crisis.

Goh's Pokémon team reflects his capture-centric goal. Key partners include:
- **Scorbunny**: Caught in Galar after persistent pursuit; it evolves into Raboot during a conflict with Team Rocket and later into Cinderace.
- **Sobble**: Captured timidly in Galar; evolves into Drizzile and Inteleon.
- **Grookey**: Acquired after it separated from Team Rocket; known for mischief.
He maintains an extensive reserve roster at Cerise Laboratory, featuring species like Caterpie, Taillow, Sandile, and Mantyke caught during research tasks.

Goh's development includes reconciling with Horace upon discovering a letter explaining his absence, mending their friendship. He later departs Cerise Laboratory to travel independently while retaining ties to the research team. Participation in initiatives like Project Mew as a "Chaser" underscores his ongoing dedication to encountering Mew and completing the Pokédex.
