Nathan is a young boy with a fair-skin, big black eyes and brown hair worn with three large spikes that resemblance cowlicks. A small amount of hair sticks down at his neck. He wears his Yo-kai Watch on his left wrist.
His well known appearance is that he wears a red short sleeve shirt with a white rim on each sleeve and color. On his arm is a blue and white design. His cargo pants are light grey and worn with a brown belt, while his boots resemble a pair of white shoes accented with blue and red. Nathan also wears this in Yo-kai Watch and Yo-kai Watch 2.
In Yo-kai Watch 3, Nathan wears a red short sleeved jacket with white stars on the arms that he wears open. Beneath his jacket, he wears a blue colored shirt with a white rim. He wears a beige cargo ancle pants with brown high-top sneakers with black laces and a light brown belt.
In several episodes, Nathan wears different clothing. In Manjimutt: Part 4 until The Legend of Shogunyan, he is seen wearing an orange shirt with white rim on each sleeve and collar, matching the star at his chest and a red sweater. He wears those clothing as well in Gourmet School Lunch: Meal 4 Fried Chicken! until Yo-kai Yoink. He later re-appeared with the same clothing in Professor Vacant and the Mysterious Mansion until The Legendary Milk Cloth.
However, in Start Your Engines! The Yo-1 Grand Prix! until Yo-kai Krystal Fox, he wore new clothing based from the appearance of his clothing from Yo-kai Watch 3. He wears a blue shirt, a red short-sleeve jacket with white stars on each side, and white jeans. In Yo-kai Mistank until Yo-kai Ecolojii, he wears a white shirt, black and white striped undershirt, and red sweater, and green jeans, but from Yo-kai Oreryu until now, he wears the same clothing from Yo-kai Mistank until Yo-kai Ecolojii.
Nate still retains the same hairstyle when he was a kid, But now wears a dark-blue shirt vest over his light-blue shirt.
Nate is a fun kid but tends to come off as comedic. He enjoys being with his friends and the Yo-kai he befriended, even when they can be troublesome. His personality is very infectious and gains him many friends; however, one noticeable trait is how extremely average he is. This spreads even to his school marks and greatly annoys him, in fact he really is not average. Like most kids, Nathan does basic things- like watching television, messing up his room, staying up late at night to watch television or play games. However, he is very righteous and has a strong sense of justice when a real crisis pops up.
Nathan's dynamic with his friends is somewhat influenced by the presence of Yo-kai on his life. When a Yo-kai influences the personality of one of his friends through inspiriting, he usually tries to confront said Yo-kai, most of the times with the help of a Yo-kai he has befriended, to get him/her to stop. That said, sometimes Nathan gets somewhat 'in need' of a Yo-kai which is inspiriting his friends (such as Eddie being inspirited by Enerfly, and later by Souname), and tries to get said Yo-kai to inspirit him, with less-than-positive results. Most of the time, similarly, Nate gets inspirited by a Yo-kai, which gives a stained impression of him to his friends, but specially to Katie, as seen with Rockabelly, Dandoodle, Cheeksqueek, So-sorree, among several other cases. Nathan tries to catch the attention of Katie as a soulmate, rather than just a friend, as he has a crush on her.
As with the Yo-kai he is friends with, Nathan likes Jibanyan (though he was appalled initially when Jibanyan moves to his house and behaves reckelssly, and he even got into an argument with him) enough to be his first usual choice when summoning a Yo-kai, and his bond with him is strong enough to Jibanyan to take part in most of his antics. Nathan does not look high on Whisper's lack of knowledge about Yo-kai, as well as his needs to feed his craving for attention and his ego, though he does appreciate his presence to an extent. Although he managed to befriend more than a hundred Yo-kai, only a select few are summoned frecquently, such as Tattletell, Manjimutt (though upon him being thrown in prison, Nathan stopped summoning regularly) Roughraff, Blazion, Komasan, Robonyan (and Robonyan F), Shogunyan, Venoct, Kyubi, Baku, the trio of Classic Yo-kai (Boyclops, Pallysol, and Lady Longnek), Lie-in Heart, Faux Kappa, and Papa Bolt.
Even after meeting Hailey Anne during the quest to meet Lord Enma, he only coincides with her a few number of times. Although he gets along with her pretty much in the occations they do coincide, Nathan finds Hailey Anne's bubblyness annoying, if not apalling, and they have a sane competitive side as shown with the Y-1 Race and when obtaining a rare Space Wars collection item.
Katie is Nate's crush with Whisper and Jibanyan being the only ones to truly know Nate's secret feelings for her.
30 years later, in the Shadowside series, Katie is now Nate's wife and the mother of Natsume and Keisuke.
Natsume is Nate's daughter, and successor after he fell out with the Yo-kai and the watch when he became an adult.
Keisuke is Nate's youngest son whom strongly resembles him.
Aaron is Nate's Father.
Lily is Nate's mother. She seems to have anger issues when her son Nate doesn't obey her but despite this, she's a loving mother who cares for her son.
He's friends with them.
