Grover Underwood ¹

Aryan Simhadri, who plays Grover, has a youthful appearance and a slender build. He is 5'7" (1.70 m). He has brown skin, a round face with soft features, large, expressive brown eyes, thick eyebrows, and abundant, curly black hair. His expression usually conveys warmth, kindness, and a touch of nervousness, giving him an approachable and likeable presence. He looks like a normal teenager, except that he has small horns and goat legs from the waist down; he usually wears jeans, so they aren't very noticeable. In any case, his small horns and goat legs aren't visible to non-half-bloods since the veil/mist conceals them. He hasn't worn his hat for a long time.

Grover doesn't chew cans. He doesn't bleat. He doesn't have a tail.

Walker Scobell, who plays Percy, has a youthful and athletic appearance. He is of average height—5'9"—with a slim but strong build, fair skin, an oval face with soft features, large, expressive blue eyes, light eyebrows, and short, slightly tousled light blond hair. His expression often conveys curiosity, determination, and a touch of mischief, giving him an energetic and charismatic presence.

Leah Sava Jeffries portrays Annabeth with a youthful and athletic appearance. She is 5 feet tall.

Charlie Bushnell, who plays Luke, has a youthful and athletic appearance. He is tall—5'7"—with a slim but strong build, fair skin, an oval face with a strong jawline, warm and expressive brown eyes, thick eyebrows, and dark brown hair that is slightly wavy and usually styled in a tousled way. His smile is typically relaxed and charismatic, giving him a friendly and self-assured presence.
