Because of his desire to catch every single Pokémon, there is, he'll sometimes become discouraged either whenever someone catches a Pokémon that he wanted to catch or if the Pokémon turns out to already belong to someone else. 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. However, Goh overtime does realize he needs to battle Pokémon if they refused to be caught right away. 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. Despite his deep knowledge of Pokémon, Goh is still new and inexperienced when it comes to being a Trainer. Additionally, despite Goh's confident demeanor, he is apparently very easy to fluster and embarrass, as he blushes often. However, overtime, Goh has formed bonds with his Pokémon, especially Cinderace, Inteleon and Grookey. While Goh clearly loves Pokémon and gets excited about meeting them much like Ash does, he seems uninterested in actually forming emotional bonds with the Pokémon he catches, unlike Ash. This trait appears when he becomes upset that his argument with Ash almost ruined their friendship. 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. 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.
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 a stylish, cool-headed boy with a confident demeanor and a hot competitive streak. 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 new Pokémon and seeks to complete the Pokédex. 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, black pants and a light gray cap.
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. He has a pair of black swim trunks, similar to what Ash wore in Alola, with red stripes instead of white. His outfit consists of a red and grey short-sleeved top with a Poké Ball design, black sweatpants, red socks, and a pair of grey and black shoes.ĭuring the Darkest Day arc, Goh receives a Dynamax Band which he wears on his right wrist. He has messy black hair with two red highlights, tan skin, and blue eyes. Goh is a skinny young boy that has a slightly androgynous appearance.
