3RACHA (쓰리라차) is not just a sub-unit – they are the creative engine that makes Stray Kids one of the most distinctive self-producing K-pop groups in the world. Long before their official debut under JYP Entertainment, these three incredibly talented individuals – Bang Chan (CB97), Changbin (SPEARB), and Han (J.ONE) – were already crafting music in dorm rooms and late-night studio sessions, shaping a sound that would eventually take the global Korean hip-hop scene by storm.

Bang Chan (CB97) – The Leader Who Never Sleeps
Bang Chan is the beating heart of both 3RACHA and Stray Kids. Known for his late-night production sessions (his infamous “Chan’s Room” live streams have made him a fan-favorite for his openness and warmth), Bang Chan is the kind of artist who pours every ounce of himself into his music. Growing up in Sydney, Australia, he brings a uniquely global perspective to K-pop music production – and fans everywhere love him for it.
Bang Chan
He was born in South Korea but moved to Sydney, Australia at a young age, attending Newtown High School of the Performing Arts before training at JYP.
Bang Chan trained under JYP Entertainment for approximately 7 years – one of the longest training periods in recent K-pop history.
He personally designed the original Stray Kids logo during their survival show formation period.
As CB97, his stage name combines “Chan Bang” and “97” (his birth year), showing how deeply personal his artistic identity is.
He speaks fluent Korean, English, and Japanese, and a bit of Chinese – making him the group’s go-to for international communication.
Bang Chan can play both guitar and piano, adding yet another layer to his already impressive musical toolkit.
His go-to comfort activity? Eating cheesecake while watching a movie – a detail fans love to quote.
He has a beloved pet dog named Berry, who makes frequent appearances in fan discussions.
His nicknames from Stray Kids members are “Kangaroo” and “Koala” – a nod to his Australian upbringing.
Bang Chan’s motto is “Just enjoy~” – a deceptively simple phrase that captures his philosophy of finding joy in the creative process, no matter how hard things get.
Changbin (SPEARB) – The Rap Powerhouse with a Heart of Gold
If Bang Chan is the backbone of 3RACHA, Changbin is the fire. His rapid-fire, technically complex rapping style – often clocking some of the fastest lyrical delivery in K-pop rap – has made him one of the most recognized voices in the entire fourth-generation idol landscape. But beneath that intense stage persona is a surprisingly warm and funny person who loves his friends deeply.
Changbin
Changbin was scouted directly by JYP Entertainment – a testament to the raw talent he had even before formal training.
He uses the stage name SPEARB in 3RACHA, reflecting the sharp, piercing quality of his lyricism – like a spear through sound.
Despite his powerful image, Changbin was reportedly reluctant to leave his family to pursue his idol career; his parents were reportedly more excited about his JYP acceptance than he was.
He is known for his incredible rap speed, frequently drawing comparisons to some of the fastest rappers in Korean hip-hop history.
Changbin has a representative animal: the “Pabbit” (a pig-rabbit hybrid that fans created), which perfectly captures his adorable off-stage personality.
He is deeply into fitness and working out, with his physical transformation over the years becoming a celebrated topic among fans.
His favorite color is black, which lines up beautifully with his intense, no-frills artistic style.
As a young teenager, Changbin penned the lyric “1, 2, 3RACHA get spotlight” in 2016 – a lyric that turned into a self-fulfilling prophecy.
He is an ESTP personality type (MBTI), making him bold, practical, and full of spontaneous energy – qualities that translate directly onto the stage.
Changbin’s motto is “Let’s eat well and live well” – a refreshingly grounded outlook for someone who operates at such a high creative intensity.
Han (J.ONE) – The Emotional Core of 3RACHA
If there is one member of 3RACHA whose lyrics consistently move people to tears, it is Han. A rapper, vocalist, songwriter, and all-around creative force, Han joined JYP after winning a rap competition in Malaysia – a detail that says everything about the natural genius underneath his careful, deliberate artistry. His songwriting digs into anxiety, loneliness, youth, and hope in ways that resonate across cultures and languages.
Han
Han’s stage name J.ONE is a clever wordplay – “J” from his given name Jisung, and “ONE” from “Han” (한), which means “one” in Korean.
He discovered his passion for rap at a young age and entered competitions, eventually winning one in Malaysia that set him on the path to JYP Entertainment.
Han has trypophobia – a fear of clusters of small holes – a surprisingly personal detail he has shared openly with fans.
His role model growing up was Block B’s Zico, one of the most respected self-produced artists in Korean hip-hop, which explains a lot about Han’s lyrical depth.
Han is regarded as the emotional heartbeat of 3RACHA – his lyrics are the most personally vulnerable, exploring themes of mental health, self-doubt, and the pressures of youth.
He is remarkably skilled at drawing characters, a hobby that shows his creative energy extends well beyond music.
Off stage, Han is described as endearingly chaotic – prone to swinging between deep sensitivity and ridiculous comedy, sometimes in the same breath.
His MBTI type is INFP, which aligns with his introspective, emotionally driven songwriting approach.
Han was once referred to by fans as the “maestro of melodies” within 3RACHA, a title he has clearly earned through years of emotionally resonant songwriting.
His personal motto – “This too, shall pass” – is a quiet reminder that his music, while deeply emotional, always carries a current of resilience and hope beneath it.
Achievements
3RACHA has not just built a career – they have quietly rewritten the rules for what self-producing K-pop idols can accomplish. Here are the landmark achievements that define their legacy:
Historic Milestones
In February 2023, all three members – Bang Chan, Changbin, and Han – were officially promoted to regular members of the Korea Music Copyright Association (KOMCA). This made them the first fourth-generation idols to ever receive this distinction, recognizing the sheer volume and quality of original work they have produced since debut.
Before that, in November 2023, 3RACHA became the first fourth-generation group to each accumulate 100 cumulative weeks on the Billboard Japan Hot 100 Lyricists and Hot 100 Composers charts – a staggering testament to their prolific output and international reach.
The trio has been credited on the vast majority of Stray Kids’ entire discography since 2018 – well over 200 songs – making them one of the most productive and influential production units in modern K-pop.

What to Expect at a Stray Kids / 3RACHA Live Show
If you are heading to see them at Governors Ball or Rock in Rio this year, here is what you should know: a typical Stray Kids concert runs like a cinematic experience. The show opens with dramatic VCR (video clip) intros, transitions into high-energy group performances, and often features dedicated sub-unit stages – meaning there is a very strong chance you will see Bang Chan, Changbin, and Han perform exclusively as 3RACHA during the show, delivering aggressive, experimental hip-hop cuts straight from their mixtape era.
Fan chants are a huge part of the experience, and the emotional connection between Stray Kids and their audience is something long-time concert-goers consistently describe as unlike any other live show in K-pop. If you only get to see one K-pop act live in 2026, make it this one.
