(L-R) The original ten. Wooseok, Shinwon, E'Dawn, Yeo One, Jinho, Hui, Kino, Hongseok, Yuto, Yanan

Pentagon is a South Korean boy band consisting of nine (formerly ten) members. They debuted on October 10, 2016 under CUBE Entertainment with the song 'Gorilla'.

The original group of ten members was formed on the Mnet survival show Pentagon Maker. It involved each member undertaking various tasks and performances for points, which would then contribute to their 'pentagram', a diagram showcasing their scores in five different categories- vocal/rap, dance, talent, teamwork, and attitude (referred to as 'mind'). Each category represented an attribute thought to be important for an idol to have.

On completion of their pentagram, each member would become part of Pentagon and thus be allowed to debut. By the end of the show, seven members had been confirmed as official members of the group, while three members- E'Dawn, Yan An and Shinwon- had been eliminated. Despite the elimination process, all ten debuted together.


Along with several concerts, fan meetings and showcases, the band have had a world tour named PRISM which ran from April 27, 2019 to December 21, 2019. They have also had a short tour in Japan named Dear Cosmo.

     E'Dawn controversy 

  • E'Dawn came under some controversy in late 2018 following the public disclosure of his relationship with fellow idol HyunA, who was also signed under CUBE Entertainment and performed with him and Pentagon's leader Hui as part of the group Triple H. CUBE Entertainment officially confirmed the termination of HyunA's contract on October 15th, 2018 and the termination of E'Dawn's contract on November 14th, 2018.

  • Both him and HyunA signed under PSY's music label P NATION on January 27th, 2019. He has since changed his stage name to Dawn and released his first solo digital single ('Money') on November 5th, 2019.


Pentagon provides examples of the following tropes:

  • Alliterative Name: Jo Jinho.
    • Also Kang Kino, if you use his stage name.
  • Album Single:
    • From the Korean EPs:
      • Pentagon has "Gorilla".
      • Five Senses has "Can You Feel It" and "Pretty Pretty".
      • Ceremony has "Beautiful" and "Critical Beauty".
      • Demo_01 has "Like This".
      • Demo_02 has "Stay" and "Runaway".
      • Positive has "Shine".
      • Thumbs Up! has "Naughty Boy".
      • Genie:us has "Sha La La".
      • Sum(me:r) has "Humph!".
      • Universe: The Black Hall has "Dr. Bebe" and "The Black Hall".
    • From the Japanese EPs:
      • Gorilla has "Gorilla".
      • Violet has "Violet".
      • Shine has "Shine".
      • Cosmo has "Cosmo".
      • Happiness / Sha La La has, you guessed it, "Happiness" and "Sha La La".
  • A Wild Rapper Appears!: Yuto and Wooseok, the rappers of the group.
    • E'Dawn was also part of this trope.
  • Big Little Brother: Wooseok, who is both the youngest and tallest member, at 6'2". In comparison, Jinho is the oldest and shortest member, at 5'6".
  • Big Ol' Eyebrows: Yuto.
  • Boastful Rap: 'Pretty Boys'.
  • Boy Band
  • Call-and-Response Song: Every song with a fanchant counts as this. For example, in 'Shine':
    E'Dawn: neoreul saranghaneun jjijiri
    Audience: jjijiri
    Hui: geurae naneun meojeori
    Audience: meojeori
    E'Dawn: nan neohanteneun geomeori
    Audience: geotjeori
  • Call-Back: In "Round 1", Yeo One is criticised for not flushing the toilet. Come "Round 2", when Hongseok wakes up in Yeo One's body, the first thing he does is to check if he's flushed the toilet.
  • Catchphrase: "Tentastic!"
  • Chronological Album Title: Demo_01 and Demo_02.
  • Concept Album:
    • Thumbs Up! had a playful, childish concept based around a frog-based Korean idiom.
  • Cuddle Bug: Yuto, who is frequently seen back-hugging the other members on camera.
  • Dancing Is Serious Business: The MV of 'Pretty Pretty', which involves Yeo One and Kino's characters facing off in a dance battle to impress their love interest. Yeo One's character eventually wins her favour.
  • Death Is a Slap on the Wrist: Shinwon, E'Dawn and Yanan were eliminated from Pentagon Maker but still ended up in the band anyways, making the whole elimination process redundant (despite the sadness it caused at the time).
  • Even the Guys Want Him: Special mention goes to Yanan here. Yuto has said multiple times that he was awestruck by Yanan's figure and how handsome he was the first time they met.
  • Face–Heel Turn: Pentagon have recently gone from a very cheerful and childish concept ("Naughty Boy") to something darker and twisted ("Dr. Bebe"). If we consider them as characters in their own music videos rather than performers, they've done a complete 180.
  • Family Theme Naming: Both the band and its company are named after shapes.
  • Fanboy: Shinwon is this of Harry Styles.
  • The Fashionista: Shinwon, who has also participated in several fashion shows. Hui as well, now that he has his own webseries called Hui's What To Wear Today.
  • "Freaky Friday" Flip: "Round 2" revolves around this trope.
  • Gentle Giant: Wooseok.
  • Guyliner: Most K-Pop boy groups wear make-up, Pentagon included, but they don't overdo it.
  • High School A.U.: The music videos for "Shine", "Pretty Pretty", and "Humph!" play on this.
  • Idol Singer: As K-Pop idols, all ten members are part of this trope.
  • Impractical Musical Instrument Skills: E'Dawn pretending to play the intro to "Shine" while crouched down. If he was playing it on a real piano, this would be really impractical. He wouldn't even reach the keys!
  • Inopportune Voice Cracking: This happened to Shinwon while singing 'Shine' on Arirang Radio's "K-Poppin'".
    Shinwon: gyeolguge nAan - - what?!
  • Jack-of-All-Stats: Of the ten participating members on Pentagon Maker, Wooseok and Yeo One had the median starting scores of the group (16) - both with vocal/rap 3, dance 3, teamwork 4, mind 3 and talent 3.
    • The entire list of Pentagon's starting stats are as follows, from best to worst:
      • Hui - vocal 4, dance 4, teamwork 4, mind 4, talent 3 = 19
      • Kino - vocal 3, dance 4, teamwork 4, mind 4, talent 3 = 18
      • E'Dawn - rap 4, dance 4, teamwork 3, mind 3, talent 3 = 17
      • Jinho - vocal 4, dance 3, teamwork 3, mind 4, talent 3 = 17
      • Wooseok - rap 3, dance 3, teamwork 4, mind 3, talent 3 = 16
      • Yeo One - vocal 3, dance 3, teamwork 4, mind 3, talent 3 = 16
      • Hongseok - vocal 3, dance 2, teamwork 2, mind 4, talent 3 = 14
      • Yuto - rap 2, dance 3, teamwork 3, mind 4, talent 2 = 14
      • Shinwon - vocal 2, dance 2, teamwork 3, mind 3, talent 3 = 13
      • Yanan - vocal 2, dance 2, teamwork 3, mind 3, talent 3 = 13
  • Jack-of-All-Trades: Kino is a talented singer-songwriter who also choreographs the majority of Pentagon's dance routines.
  • The Leader: Hui.
  • Loser Protagonist: The narrator of Shine is this. The song's most-repeated word, jjijiri, even translates to "loser" in most English translations.
  • Lovable Jock: Yuto, who played baseball for six years and soccer for two.
  • New Sound Album: Although it had some stylistic similarities to Positive, Thumbs Up! had much more of a childish, happy-go-lucky feel than their older work, and definitely a more cheerful concept. They said themselves that the album was meant to appeal to children.
    • Compared to Positive and Thumbs Up!, Universe: The Black Hall is incredibly dark, with deeper and more soulful tracks. The MV teasers for "Naughty Boy" and "Dr.Bebe" are chalk and cheese.
  • Older Than They Look: Jinho is almost six years older than Wooseok, but his height and youthful features have caused this trope.
  • Power Trio: Yuto, Wooseok and E'Dawn- the rap line- before E'Dawn left the group in 2018.
  • Proud Beauty: Shinwon, as seen during Pentagon Maker. Special mention goes to when the group played Buzzfeed's Who's Who, and they were asked who was the best looking. Shinwon pointed at himself; and when Kino asked him why, he responded with "this is [the] reason".
  • Sampling: Pentagon sampled Elvis Presley's 'Jailhouse Rock' for their song 'Critical Beauty'.
  • Silly Love Songs: 'Shine', 'Pretty Pretty' and 'Naughty Boy', among others.
  • Singer Name Drop:
    • Most of Yuto's rap breaks are preceded by the words Yuto da, which mean 'it's Yuto'.
      • Kino's similar tag, Knnovation (Kino + innovation), is found in "Genius" and "Round 1".
      • In "Round 1", there are five instances of Yuto da, because Hui is making fun of it.
    • Many, many examples in 'Pentagon'.
      You're my universe, universe, I can be your pentagon, hey!
    • Kino-ya in "The Greatest Wall". Kino also calls Hui hyung in the song.
    • Wooseok-ah in "Just do it yo!!". In the same song, Pentagon directly name-drop the fanbase (UNIVERSE!).
    • Kang Hyunggu! pops up in "Genius", as well as Wooseok, Yuto and Yanan being mentioned by their dads.
    • Every member except for Shinwon and Wooseok are called by their real names at least once in "Round 1". Shinwon is simply referred to as hyung, and Wooseok's name isn't mentioned at all.
  • Solo Side Project: Hui and E'Dawn, along with E'Dawn's girlfriend and fellow idol HyunA, formed the side group Triple H in 2017. Following both Hyuna and E'Dawn's resignation from CUBE Entertainment in late 2018, it is unlikely Triple H will perform again.
  • The Something Song: 'Organic Song'.
  • Stage Names: Hui and Yeo One use stage names that are variants of their actual name, while Kino uses (and E'Dawn used) a completely unrelated stage name. Everyone else in Pentagon uses their real name or part of it.
  • Studio Chatter: At the end of 'Naughty Boy'.
  • Surprisingly Good Foreign Language:
    • Pentagon often use Japanese in their songs, from moments of Gratuitous Japanese (such as in "Pretty Boys") to full songs in Japanese (such as "I'm fine"). Needless to say, they use it correctly.
      • This trope also applies to Yuto rapping, singing and speaking in Korean, considering it isn't his native language and he's been shown to have trouble with it before (in word-based games, for instance). It has been said that he writes songs with a dictionary in his hand to make sure he gets the vocabulary right.
  • Tall, Dark, and Handsome: Wooseok and Yuto, two of the tallest members. Yuto in particular wears a lot of black outfits, so the 'dark' part of this trope certainly applies.
  • Team Hand-Stack: Before they go on stage, the members do this and shout "Just do it yo!!". They tend to film this moment and several videos of the chant can be found on social media.
  • Theme Naming: Triple H was so named because of its members, HyunA, Hyojong and Hui.
  • Three Second Silence - 'Naughty Boy' opens with five seconds of construction noises and no music as the camera zooms in on Hui sitting in the frog position.
  • Vocal Tag Team - Most K-Pop groups utilise this technique and Pentagon is no exception, especially with nine members.
    • In Pentagon, usual custom is that vocals are most heavily divided between Hui and Jinho (who are widely considered to be the strongest vocalists of the group), and following them, the other members get a varying amount depending on the song and the vocal range required. Yuto and Wooseok (and E'Dawn, previously) tend to get an equal amount of lines due to the fact that they make up the rap breaks.
    • The order of who sings when tends to be different each time, but Yuto tends to feature near the end/last in most Pentagon songs, most likely because his section is often announced (see Singer Name Drop above).
  • You Gotta Have Blue Hair: There have been various examples of this throughout the years, as with most K-Pop groups.
    • Wooseok - green, bleached, red
    • Hui - red, purple, blue
    • Yuto - blue-green, silver, brown with highlights
    • Kino - white, black-and-white, red
    • E'Dawn - blonde, blue, pink
    • Yanan - red, blonde, black
    • Jinho - pink, blonde, black, silver
    • Changgu - white

How well does it match the trope?
