Block B rapper · BASTARZ member · actor · variety performer · Theater Company Boy co-founder
P.O
Pyo Ji-hoon, known as P.O, is Block B’s youngest member and deepest rap voice, one third of BASTARZ, a solo songwriter, an actor represented by Artist Company and a co-founder of Theater Company Boy. He can make one syllable sound like furniture moving downstairs, then spend an entire variety episode looking sincerely betrayed by a quiz.
RaeRae take
P.O’s “duality” is not a magic switch between cute and scary. It is one theatrical brain using scale. The low voice can turn a Block B entrance into a warning, the broad face and physical timing can turn confusion into comedy, and the same instincts can become restraint when a drama scene needs a human being rather than an idol cameo.

Actor was the first dream
P.O received acting lessons when he was young and attended Hanlim Multi Art School, where performance existed before the public knew him as Block B’s low-voiced youngest member. Hip-hop and idol training redirected the route without erasing the original interest.
That order matters. Acting is not a retirement plan attached after music schedules slowed; it is one of the earliest threads in the biography.
The pre-debut friendship with Mino
P.O and Song Mino built a friendship before either man’s most famous group identity settled into place. Both moved through trainee uncertainty, rap ambition and later television work, giving their public chemistry years of untelevised history.
Their friendship is entertaining because neither has to manufacture instant intimacy for a camera. Competition can become loud without making the relationship fragile.
A voice with its own floor
P.O’s low register creates immediate contrast against Zico and Park Kyung. He can use it as blunt force, comic exaggeration or a warm rumble depending on how much space the production leaves.
Depth alone is not technique. The memorable choice is rhythm: where he lands consonants, drags a vowel or waits half a beat longer than the listener expects.
The youngest member is not the smallest presence
Maknae language can reduce an adult performer to permanent baby status. P.O is the youngest Block B member, but his physical scale, voice and theatrical confidence often make him one of the largest shapes in a frame.
The group enjoys the contradiction. He can deliver menace, then lose an argument with the energy of a deeply offended puppy.
NalinA
On “NalinA,” P.O’s entrance changes the weight of the production. The bright brass suddenly has a basement to push against, and the rival-crew concept gains a voice capable of making its melodrama sound briefly credible.
He also participates fully in the ridiculous dance. Block B’s power comes from refusing to choose between threat and joke.
NILLILI MAMBO
The pirate excess of “NILLILI MAMBO” gives P.O an ideal visual world: coats, swagger, fights and a plot only loosely supervised by reality. His low delivery makes the cinematic concept feel inhabited rather than rented.
A voice this distinctive becomes part of production design. Remove it and the same instrumental stands in a different room.
H.E.R and melodic surprise
“H.E.R” uses P.O’s weight inside a bright, infatuated pop song, proving that a low rapper does not require permanent darkness. His sung and rhythmic moments make sweetness feel playful rather than polished into anonymity.
Fans who discover his vocal color there often find that the supposed gap between rapper and singer was mostly a filing choice.
BASTARZ begins with zero conduct
P.O joined U-Kwon and B-Bomb in BASTARZ, debuting with “Zero for Conduct” in 2015. The unit concentrates bass, performance force and a more openly dangerous frame than many Block B group singles.
P.O is not merely the low voice placed over two dancers. His writing and later production participation help the unit develop beyond one aggressive concept.
Welcome 2 Bastarz
The second BASTARZ project widened the unit through “Make It Rain,” “Selfish & Beautiful Girl” and member-involved tracks. P.O contributed writing, composition and arrangement across material that showed more than one shade of trouble.
A subunit becomes meaningful when it discovers internal range, not when it repeats the debut louder.
I’m a Mess
The 2019 BASTARZ release I’m a Mess included deeper member participation and songs such as “Help Me.” P.O’s credits across the unit make clear that his musical role extends beyond receiving a rap verse.
The title fits a group whose best work often sounds disordered from outside and carefully mapped from within.
MEN’z NIGHT
P.O’s 2017 solo single “MEN’z NIGHT,” featuring Chancellor, leans into retro showmanship, brass, suits and a grown-man performance staged with a grin. The official video supplies this page’s distinct real profile image.
The song understands that masculinity can be theatrical without becoming anxious about color, dance or humor.
Comme des Garçons
“Comme des Garçons,” also circulated through the Korean title meaning “Like a Boy,” uses fashion language and memory to examine boyhood, growth and self-presentation. P.O wrote, composed and arranged the single.
The title is not a luxury label pasted onto an empty flex. It becomes part of the question about what remains when a boy learns to dress like the man people expect.
Promise with Mino
“Promise” pairs P.O with Mino in 2019, bringing the long friendship into an official recording. Familiar chemistry allows the track to feel personal without requiring a documentary speech before every line.
A collaboration between friends still needs a song. The relationship supplies texture; writing and arrangement give that texture somewhere to live.
Writing credits
P.O has writing and composition credits across solo work, BASTARZ songs and selected collaborations. Exact roles vary by recording, so the profile distinguishes lyric, composition and arrangement rather than inflating every contribution into “produced everything.”
Credit precision respects him more than mythology. It lets readers see growth from performer to maker through specific records.
Diction and the weight of consonants
A low voice can blur inside heavy bass if the rapper relies on tone alone. P.O keeps sections readable by giving consonants hard edges and allowing pauses to separate one physical phrase from the next. The delivery often feels slower than it is because each entrance carries unusual mass.
That control also makes comic exaggeration possible. He can over-round a sound or punch one word without losing the beat underneath the character choice.
The singing voice
Block B tracks such as “H.E.R,” “A Few Years Later” and “Toy” let listeners hear P.O beyond the expected low rap attack. His sung tone remains textured and immediately identifiable, adding warmth rather than pretending to become a conventional main vocalist.
The point is not to prove he can replace Taeil. It is to use another part of his instrument when the song benefits from it.
Ensemble instinct across three jobs
Group music, theater and variety all require a performer to understand when somebody else owns the moment. P.O can be visually enormous, but his strongest ensemble work includes listening, reacting and preparing the next person’s payoff.
That skill links careers that look unrelated on a résumé. A rap handoff, a stage cue and a variety reaction all depend on timing shared with other people.
Theater Company Boy
P.O co-founded Theater Company Boy with friends, creating a stage home rather than waiting for television casting to define him as an actor. Theater demands repetition, projection, ensemble trust and the ability to sustain a character without editing.
That work explains why acting belongs at the center of this profile. It is craft pursued through an institution he helped build, not a promotional side quest between comebacks.
Stage acting
Plays let P.O use the same scale that serves variety and rap, then discipline it across a live arc. A gesture that delights on television can overwhelm a theater scene if the character has not earned it.
The stage teaches calibration without close-ups. Every performance has to reach the back row and remain truthful to the person beside him.
Drama work
P.O expanded through dramas including Temperature of Love, Encounter, Hotel del Luna, Mouse and Good Partner. The roles moved him from recognizable idol casting toward a steadier acting file.
A profile should name the work without pretending every role is equally large or acclaimed. Progress lives in accumulated scenes, better control and directors willing to cast him again.
Hotel del Luna
As Ji Hyun-joong in Hotel del Luna, P.O brought warmth and sadness to a hotel employee whose cheerful surface sits over unfinished life. The role used his natural likability while asking it to carry loss.
That is stronger casting than making him a loud comic guest because viewers recognize him from variety.
Good Partner
Legal drama Good Partner gave P.O another current acting route and continued through later production activity. Artist Company presents him as Pyo Ji-hoon in the acting file, while P.O remains the music-stage name.
Two names do not mean two people. The page keeps acting and music together so audiences can follow the actual career rather than choose a database silo.
New Journey to the West
P.O became a major variety presence through New Journey to the West, where his friendship with Mino, earnest reactions and spectacular quiz failures created recurring comedy. He does not protect a cool rapper image when being wrong is funnier.
That willingness is a professional skill. Variety depends on giving editors usable truth without making every moment feel calculated.
Kang’s Kitchen
The restaurant spinoff turns comedy into labor: preparation, service, mistakes and teamwork under cameras. P.O’s warmth and capacity to be flustered make him readable, while the work prevents charm from becoming the only assignment.
Food television exposes whether a performer can share attention with an actual task.
The Great Escape and other variety rooms
Adventure and puzzle formats use P.O’s physical expressiveness and group instincts differently from a talk show. Fear, confusion and sudden insight become visible before he has time to arrange them into a polished answer.
His value is not being the smartest contestant in every room. It is making the room emotionally legible while the problem unfolds.
Military service in the Marines
P.O enlisted in the Republic of Korea Marine Corps in March 2022 and completed service in September 2023. He spoke publicly about wanting to meet the requirements of that branch despite initial application difficulty.
Military service is a dated obligation in the biography, not a personality award. Completion reopened acting and variety schedules; it did not automatically solve seven Block B calendars.
Artist Company
After leaving Seven Seasons for individual representation, P.O joined Artist Company, an agency centered strongly on actors. Its current official profile uses his birth name, Pyo Ji-hoon, and frames an acting career still expanding.
Changing agencies for solo work did not remove him from Block B. The distinction is precisely why group status and personal management need separate fields.
The 2026 accident belongs in proportion
Artist Company reported that P.O sustained minor injuries in a July 2026 traffic accident in Jeju and expected him to continue scheduled work. The event belongs in a current health note, not as dramatic content or a reason to invent long-term consequences.
Responsible updating records confirmed facts, avoids graphic speculation and changes the page again if the agency provides meaningful new information.
Friendship is not a marketing unit
P.O and Mino’s television chemistry is so popular that coverage can treat the friendship as a permanent double act. Their bond matters, but each man has separate group, music and acting histories.
A good profile lets “Promise” and variety episodes connect them without making one person an accessory in the other’s biography.
Fashion and the broad silhouette
P.O can carry oversized tailoring, retro suits and bold color because his performance does not shrink when the clothing expands. “MEN’z NIGHT” and “Comme des Garçons” make style part of the musical argument.
Fashion here is character direction, not proof that a logo wrote the song.
Aquarius and the zodiac side quest
P.O was born under Aquarius, popularly associated with independence, odd humor and loyalty to chosen communities. The shorthand fits a theater co-founder who can look completely sincere while the rest of a variety set questions his operating system.
His Chinese zodiac is the Water Rooster, linked traditionally with expressiveness and social awareness. Astrology is seasoning; acting lessons and years of ensemble work explain more.
Rant: comic timing is not lack of intelligence
Variety programs build jokes through wrong answers, confusion and reaction shots. Viewers sometimes confuse a successful comic role with evidence that the performer is foolish off camera. That mistake ignores editing, format and the intelligence required to keep a scene alive.
P.O can be genuinely baffled and professionally generous at the same time. Comedy does not need a secret genius defense to deserve respect.
Block B is present tense
P.O left Seven Seasons for individual management, completed service and built a serious acting calendar. None of those facts made him a former Block B member. The group remains a seven-person identity working across separate structures.

How to listen and watch
Start with Block B’s “NalinA,” “NILLILI MAMBO,” “H.E.R” and “Toy.” Enter BASTARZ through “Zero for Conduct,” “Make It Rain” and “Help Me,” then use “MEN’z NIGHT,” “Comme des Garçons” and “Promise” for the solo file.
For acting, sample Hotel del Luna and Good Partner; for variety chemistry, use New Journey to the West and Kang’s Kitchen. The routes illuminate different tools.
