*Ateez*

He often looks calm and serious compared with the other members.
Jongho is the responsible baby of the group.
He's generally more composed and practical than some of the other members. He has a dry sense of humor and isn't afraid to tell the older members when they're being ridiculous.
But he's also affectionate and playful when he's comfortable.
And then there's his voice.
Jongho is famous for his extremely powerful vocals. He's the kind of singer who can stand there looking completely calm and then suddenly produce a gigantic high note.
He's also known for his strength—he has famously demonstrated things like breaking fruit with his hands.

Wooyoung has a very expressive face, sharp eyes and a mischievous smile. He's smaller than Yunho/Mingi but has huge stage charisma.
He's also extremely expressive when dancing.
Wooyoung is probably one of the most openly affectionate and outgoing members.
He's loud, playful, teasing and extremely social. He's the sort of person who will happily bother his friends just because it's funny.
He's also incredibly loyal. His friendships with the other members are a huge part of his personality.
He's especially close with San, and the two have a very affectionate, chaotic friendship.

Mingi is very tall, around 184 cm, with long limbs and a strong stage presence. His deep voice contrasts hilariously with his appearance.

He's actually really goofy.
Mingi can be loud, playful and incredibly funny, but he's also more sensitive and thoughtful than his stage persona might suggest.

He's also one of the members who can make ATEEZ's dorm/group content feel like a sitcom.

Yeosang has a very striking, almost unreal-looking face. He's known for his sharp features, pale complexion, distinctive eyes and very model-like appearance.
He's one of those idols where photos can make him look incredibly intimidating or regal. Offstage, he's considerably more reserved than his appearance suggests. He's calm, sometimes quiet, and has a very dry sense of humor.
And then occasionally he'll say something completely ridiculous with an absolutely straight face.
He's also competitive and can be surprisingly mischievous and he's Korean.

San has a very expressive face, beautiful eyes and a strong, athletic physique. He's particularly famous for his facial expressions while performing.
Seriously, if you've watched an ATEEZ performance and thought "WHO IS THAT GUY?!" there is a decent chance it was San.
This is one of the biggest contrasts in ATEEZ.
San is incredibly affectionate, emotional and caring. He loves physical affection and is very attached to the members. He's also known for loving plushies.
He's hardworking and takes performing extremely seriously, but he's also very playful and goofy around people he's comfortable with. he's Korean

Yunho is the tallest member, around 186 cm. He's broad-shouldered, athletic-looking and has a very warm smile.

He's extremely comfortable around the other members and loves joking around with them. He also Korean.

Seonghwa has a very classically handsome, almost ethereal appearance. Tall and slender, sharp jawline, beautiful eyes and very expressive facial features. He can pull off both masculine and delicate styling extremely well.
He has often had long-ish hairstyles, dark hair, blond hair, etc., and somehow manages to look good in basically everything. He's often described by fans as the group's "mom" because he's extremely caring and attentive to the other members. He's organized, gentle and tends to notice when someone needs help.
But there's another side to him: Seonghwa is WEIRD.
He can be incredibly dramatic, silly and easily excited, especially when he's comfortable with the members. He's also very affectionate.
He's known for being meticulous and taking pride in doing things properly. Hes also Korean.

Hongjoong is one of the shorter members, around 172 cm, with a very distinctive face. He has sharp features, expressive eyes, and often experiments with his hair and fashion. He can look extremely elegant one day and completely mischievous the next. He's the responsible little leader of the group. He's thoughtful, ambitious and very passionate about music and ATEEZ. He's also quite sensitive and caring toward the other members.
But don't mistake "leader" for "serious all the time." Hongjoong is tiny chaos around the members. He's witty, playful and has a surprisingly dramatic side and he's Korean.
