Jason Grace is described to be extremely handsome, and he is arguably the most attractive demigod in the series. Jason has the regal features of a Roman statue, electric blue eyes, and close-cropped blond hair that grew out during his time at Camp Half-Blood. Jason also has a small scar on the corner of his lip from trying to eat a stapler when he was two years old. Piper noted that the scar makes him look even more attractive. People say his face looked gentle but a bit sad.

Will is noted as having a surfer-body, shaggy curly blond hair, blue eyes, and having an athletic build. His appearance reminds Nico of Jason Grace in The Blood of Olympus. He typically dresses casually in a T-shirt and shorts. Rick Riordan has stated that Will is in Nico's age group, making him about 15 years old. In The Hidden Oracle, Will estimates Apollo's appearance as Lester to be about his age, fifteen.

Luke is described as a tall, college-aged young man with an athletic, muscular build. He had short-cropped sandy blonde hair, blue eyes, a sharp nose, and the sneaky look like all Hermes demigod children. Many girls found him particularly attractive, even the Empousa Kelli. The only thing unsettling about Luke's appearance was a thick, deep pale scar that ran from the bottom of his eye down to his chin caused by Ladon, the guardian dragon of the Garden of the Hesperides.

— it's in his heart!

Ethan was a teenage boy of Japanese descent and looked to be around sixteen years old during his first fight with Percy. He had a thin build, glossy black hair, and a black eye patch over his left eye. As an enemy demigod in Kronos' army, he was generally seen wearing Greek armor; according to Percy, it hung on his body loosely due to his slim build.

۫ ꣑ৎ bad influence.

Nico has black hair that always looks like he just got out of bed (messy and shaggy) and olive skin. By The Battle of the Labyrinth, his skin has paled to white, and he takes to wearing black clothing with skeletal designs, a Stygian Iron sword and a silver skull ring (by the end of the book). By the time he meets Hazel Levesque, she describes his fingers as ghostly white, like their father's. Percy stated that Nico has his mother's eyes.

Leo is described by Jason to look like a "Latino Santa's elf," with curly black hair, dark brown eyes, a cheerful, elf-like face, normally with a mischievous and impish smile, and a diminutive stature with a slim and relatively scrawny build. He is said to be very short, implied to be between Piper and Hazel in stature. Leo's most notable trait is that he has a look in his eyes that makes him look not only like a troublemaker.

— just like the books.

Percy has tan skin, disheveled, jet-black hair swept to one side as "if he just took a walk to the beach" and sea-green eyes, which he inherited from his father and grandmother. He also has a sarcastic, troublemaker smile. Percy gets his handsome looks from his father, a reason why Medusa wanted to preserve a statue of him. He doesn't seem to know it or may simply refuse to acknowledge it, but a great number of girls find him extremely attractive.

۫ ꣑ৎ very needy. (MLM)

He assumes the appearance of “the stranger” Addie imagined as an adolescent, a handsome man she'd fantasize about at night. He has green eyes, brown hair.

The Invisible Life Of Addie LaRue

In The Blood of Olympus, he was depicted as a seventeen-year-old youth, with curly blond hair and a perfect tan. His eyes are hazel and his face is accompanied with light freckles that complimented his face.

 Nick is extremely tall and strong for his age, standing at 6'1", and having a bulky, husky build. His strong stature is something many characters - especially Charlie - have noted, as he often picks up Charlie with ease whether he's injured or just for fun. He has dirty blonde hair shaved to the side and longer at the top, brown eyes, and a round face. His attire is usually derived of sweatshirts, hoodies, joggers, patterned socks, and low-top Vans sneakers.

In mythology, she is also described to have grey eyes, although some sources say they are blue. As a goddess, Athena is able to change her appearance at will, though she retains her stunning beauty and dignity no matter what physical manifestation she chooses.

Klaus has brown hair that darkens over the seasons, with bangs parted to his left. While it begins very straight and light, it curls and darkens over the course of the series, due to actor Louis Hynes's hair doing the same. He has light skin, hazel eyes, and brown Wayfarer glasses. While he begins about the same height as Violet, maybe slightly taller.

— library finds.

Sean has short, cropped dark brown hair and wears a maroon beanie with a yellow logo on its rim (while walking home from school).

On his feet, he wears gray running shoes with blue laces and green markings.

Ron inherited the typical Weasley family traits: fiery red hair and a freckled complexion. When he became embarrassed, his ears notably turned red. He had blue eyes, a long nose, and was described as being very tall and lanky, with big hands and feet. In this way, his stature was similar to those of his older brothers Bill and Percy, rather than the heavily built Charlie, and Fred and George.
