* BrattyHalfPint: Yujin is well-known for terrorizing her [[UsefulNotes/KoreanHonorifics unnies]], to the point of them considering her the top of IZ*ONE's hierarchy.

* NoPronunciationGuide: Averted as the correct pronunciation “eyes-one” was revealed on the final episode of Produce 48. But as Wonyoung herself has called the group “eyes-one”, “eye-zone”, and “eye-zu-won”, it’s definitely confusing.

* NoPronunciationGuide: How are you meant to say "COLOR*IZ"? Is it just "Colors"? Or (as MAMA wrote it) is it "Colorize"? If it’s the first way, is "Colors" technically a TitleTrack?
** For a long time prior to the start of their official promotions, ''Oneiric Diary'' was this for fans. Was the first word pronounced as "OH-ne-rik", "o-NE-i-rik", "ONE-rik", or what? [[note]]Eventually it was revealed to be pronounced as "own-AI-rik". [[/note]]
** ''One-Reeler'' ups the ante by introducing tracks titled "Mise-en-Scène"[[note]]pronounced "meez-uhn-sen"[[/note]] and "O Sole Mio"[[note]]pronounced "o so-le mee-yo"[[/note]].

** Post-IZ*ONE, Sakura briefly returned to Japan and attended schedules as a member of Music/HKT48. She announced her graduation from the group after a few months and signed on with Source Music to debut as a member of Music/LeSserafim alongside Chaewon with the EP ''FEARLESS'' on May 02, 2022.

** Post-IZ*ONE, Chaewon attended a few activities as a solo trainee under Woollim in 2021 before mysteriously disappearing on social media. She would eventually reappear several months later, having signed an exclusive contract with Source Music (along with Sakura) to debut as the leader of Music/LeSserafim with the EP ''FEARLESS'' on May 02, 2022.

* [[UnclePennybags Aunt Pennybags]]: After achieving good levels of domestic success, most of the girls have been very generous with their (for some, newfound) wealth. Eunbi often treats the girls and their staff with plenty of gifts, while Yena often sends food trucks in support of her friends/labelmates (like the members of EVERGLOW) and Hitomi is noted to be very diligent in buying premium gifts for their stylists and staff managers.

** Yena and Hitomi were selected to perform [[https://youtu.be/jSuGBLdL28c BOUNCE (Dubstep Ver.)]] with seniors from various groups including Music/MonstaX and {{Music/Twice}}

** Nako's fans often use [[EverythingsBetterWithPenguins penguins]] or [[ScrewballSquirrel squirrel]] to represent her.

* ThoseTwoGirls: Early on, Japanese members [[SempaiKohai Nako and Hitomi]] were often paired together not only in variety show appearances but also in line distributions in their discography due to similarly high vocal tones. Steadily being [[AvertedTrope averted]] in more recent comebacks.

* DancingIsSeriousBusiness: Chaeyeon, whose performances [[DancingRoyalty mesmerize]] not only general audiences but even the members themselves.
** Put to the test when she joins her third Mnet survival competition ''Street Woman Fighter'' after IZ*ONE's dissolution where she joins non-idol professionals (i.e. choreographers, "backup" dancers, and international contest winners) as the only contestant with an official occupation as a K-pop idol.

** Post-IZ*ONE, Sakura briefly returned to Japan and attended schedules as a member of Music/HKT48. She announced her graduation from the group after a few months and signed on with Source Music to debut as a member of LESSERAFIM alongside Chaewon with the EP ''FEARLESS'' on May 02, 2022.

** Post-IZ*ONE, Chaewon attended a few activities as a solo trainee under Woollim in 2021 before mysteriously disappearing on social media. She would eventually reappear several months later, having signed an exclusive contract with Source Music (along with Sakura) to debut as the leader of LESSERAFIM with the EP ''FEARLESS'' on May 02, 2022.

*** Related to this, a member unit known as Minchodan[[note]]''Mint Chocolate Dan'' = ''[[ExactlyWhatItSaysOnTheTin Team Mint Chocolate]]''[[/note]] consisting of Chaewon, Nako, and Wonyoung like, [[CaptainObvious you guessed it]], mint chocolate ice cream (in contrast to the rest of the group who are somewhere between neutral and strong dislike for the [[LoveItOrHateIt controversial]] flavor). (Note that their preference for mint chocolate starts and ends with ice cream.)

** Season 3 will feature Eunbi, Chaeyeon, and Hitomi going to a yet-to-be-announced locale.

** [[AvertedTrope Averted]] firmly in RealLife, however, as Wonyoung has been known for being the only member to play at the pitching event in ISAC whereas Yujin flawlessly aced her high school graduation exam ''[[UpToEleven in the midst of Oneiric Diary promotions and TWELVE preparations]]''. [[LampshadeHanging Lampshaded]] by Eunbi and the other older members who say that Yujin is [[SmarterThanYouLook smarter than she lets people on]], saying that [[GenkiGirl she]] does most of the [[TheCharmer impromptu emcee]] [[TheFace duties for a reason]].

** Nako likes ice cream ''a lot''. In fact, one of her birthday wishes is to be able [[UpToEleven to eat 100 pints in one sitting]].

* GoodWithNumbers: [[{{Main/Cloudcuckoolander}} Hyewon]], who spent a good amount of screentime in one IZ*ONE CHU: Secret Friends episode solving a math textbook [[BecomingTheMask even though they were only]] [[SugarWiki/CrowningMomentOfFunny supposed to be pretending as students]]. In a different variety show appearance later, she admits that she likes solving problems (or rather, the feeling of being able to solve problems) from time to time [[UpToEleven to relieve stress]].

* PaintballEpisode: The highlight of IZ*ONE CHU's fourth season is an [[SeriousBusiness intense game of laser tag]] complete with airsoft training courtesy of [[UpToEleven Navy SEAL Ken Rhee]].

** On the other end, the three Japanese members (Sakura, Nako, and Hitomi) are frequently noted to pick up Korean proficiency very quickly, but in different ways: Sakura is said to understand Korean quickly based on context, while Nako is often praised for her noticeable lack of a "foreign" [[SuprisinglyGoodAccent accent]] and Hitomi is said to have the best reading/writing comprehension out of the three. As proof of their [[CharacterDevelopment growth]], all three actively participated in the production of certain songs in their 2020 release ''Oneiric Diary'' — Sakura and Nako interpreted the lyrics of their title track (Secret Story of the Swan) from Korean into Japanese, while Hitomi ''wrote'' the lyrics for Merry-Go-Round in [[SugarWiki/MomentOfAwesome both the Korean and Japanese versions]].

** Sakura: Kkura[[note]]Koreans tend to abbreviate foreign names with the last two syllables[[/note]], Saku-chan[[note]]Most often used by [[FirstNameBasis Chaeyeon]][[/note]], Kim Kkura / Lee Kkura [[note]]A joke about how [[DullSurprise terrible]] she is at imitating anime-style aegyo that she's more Korean than the ''actual'' Koreans; the latter is a ShipTease nod to Chaeyeon's surname [[/note]]
** Hyewon: Kang-chan [[note]]Often used by the Japanese members[[/note]], Kwangbae [[note]]A machine mistranslation in Korean of her Japanese nickname that ended up catching on[[/note]], Selca Goddess [[note]]She's known for taking very good, almost professional-level pictures using almost any camera[[/note]]

** Hitomi: [[TheCutie Hii-chan]], [[TheOjou Hii-sama]], Tomi [[note]]Koreans tend to adopt the last two syllables of a name with multiple phonetics[[/note]], Peach [[note]]Because of her [[https://4.bp.blogspot.com/-83z3mNV2WVY/W2wzo4GtrfI/AAAAAAAALNg/CJ4-euao18oLXTqIjr-kKYheHw0iz0d7gCLcBGAs/s1600/77a730012c9297e93a0e7dca5833f6bc.jpg resemblance]] to Apeach, a LINE mascot [[/note]], Hong Dahee [[note]]A "Korean-ization" of her name, often jokingly used to refer to her more "mature" appearances[[/note]], Hitoma [[note]]Chaewon's exclusive AffectionateNickname for her[[/note]]

* BeautifulSingingVoice: Yuri is praised for her vocals as much as Chaeyeon is fawned over for her dancing skills by the group. For what it's worth, Yuri herself favors the vocals of Yujin, Yena, and Chaewon.

** Put to the test when she joins her third Mnet survival competition ''Street Woman Fighter'' after IZ*ONE's dissolution where she joins non-idol professionals (i.e. choreographers, "backup" dancers, and international contest winners) as the only K-pop idol.

* DyeHard: Related to the above, several members have had colorful hair colors with the most frequent changers being members like Yena and Sakura... though as of 2022, it seems Hitomi's the one who's consistently continued to dye her hair in any shade of vibrant color that ''isn't'' black or brown.

* FunnyCharacterBoringActor: [[AvertedTrope Averted]] to hell and back. The girls have a reputation in the industry for being one of the rowdiest and funnily chaotic groups (partly thanks to their great numbers) and a fan would believe that they may be exaggerating such behaviors for the cameras, only for industry insiders such as different variety show producers and directors to reveal that the girls are as [[SugarWiki/HeartwarmingMoments hilarious and affectionate]] with everybody even when the cameras aren't rolling.

** [[HugeSchoolgirl Yujin and Wonyoung]], on the other hand, have been very conscious of their tall frames. The two often bickered early on to compete with who was ''shorter'' between them and felt embarrassed about their heights since it can occasionally draw unwanted attention and make it more difficult for them to find clothes that would fit them. Wonyoung had even admitted wanting to stop growing during her guest appearance in [[Series/RunningMan]]. Fortunately being slowly [[{{AvertedTrope}} averted]] as of 2021 as they've started to embrace their heights more.
* TheLeader: Before their debut, Eunbi acted as their unofficial leader. On the second episode of IZ*ONE CHU, Eunbi was unanimously selected to be their official leader after a prank where members said [[NumberTwo Chaeyeon]] should become the leader.

** Yujin was also a victim of this dilemma early on with some Western sites referring to her as 'Yoojin'. Jury's still out, however, on how her last name should be romanized since some sources use 'Ahn' and others use 'An' (though it should be noted that her agency appears to favor 'An').

** On the other end, the three Japanese members (Sakura, Nako, and Hitomi) are frequently noted to pick up Korean proficiency very quickly, but in different ways: Sakura is said to understand Korean quickly based on context, while Nako is often praised for her noticeable lack of a "foreign" accent and Hitomi is said to have the best reading/writing comprehension out of the three. As proof of their [[CharacterDevelopment growth]], all three actively participated in the production of certain songs in their 2020 release ''Oneiric Diary'' — Sakura and Nako interpreted the lyrics of their title track (Secret Story of the Swan) from Korean into Japanese, while Hitomi ''wrote'' the lyrics for Merry-Go-Round in [[SugarWiki/MomentOfAwesome both the Korean and Japanese versions]].

* TotallyRadical: [[TheLeader Eunbi]] who was [[ChristmasCake born in 1995]] shows mild signs of this. She makes a lot of jokes and references that the younger kids don't understand, and members make it no secret about teasing her with her age or her attempts to seem younger.

On March 10, 2021, Mnet announced the end of the project following the original stipulations of the members' contract on April 29, 2021. This news was published in the wake of the announcement of IZ*ONE's second online concert entitled ''ONE, The Story'' held for two days on March 13 to 14, 2021 via Interpark streaming as well. However, it was also revealed on the final day of the second concert that it would be the [[TheFellowshipHasEnded last day]] of the girls' official activities as twelve members together. Hence, all succeeding releases from the group and its members until April 29th were confirmed to have been pre-recorded or booked prior to Mnet's announcement.

* Yabuki Nako (야부키 나코 / 矢吹奈子) (born June 18, 2001, ranked 6th, Music/HKT48)

*** Hyewon, Yena, Nako, and Wonyoung performed a dance cover of [[Film/Sunny Sunny]] before doing a full performance of [[{{Music/TARA}} Roly Poly]].

** Chaeyeon: [[DancingIsSeriousBusiness Feather]][[note]]After people noted that, despite the power and precision she infuses in her dancing, she moves lightly like a feather [[/note]], [[ShipTease Miyawaki Chaeyeon]] [[note]]Like Lee Kkura, a not-so-subtle ShipTease nod; ''unlike'' Lee Kkura, it's become an AscendedMeme since she introduced herself as such to Japanese fans in IZ*ONE CHU[[/note]], [[NiceHat Chaeberet]]

** Some fans believe Yena resembles Yuqi of (G)I-DLE as well. [[MemeAcknowledgment Including Yena and Yuqi]] themselves as the two have become friends recently.

** This seems to have improved considerably as of 2020: the Japanese members are comfortable enough in their Korean that they can [[https://www.youtube.com/watch?v=J21mJywMefM carry full conversations in Vlive]] and even [[https://youtu.be/sAPwXwPdnOs?t=857 sound like natives]], while the Korean members can now [[https://www.youtube.com/watch?v=MzGCoEfsYxg pronounce/enunciate Japanese syllables
more clearly]].

* AndNowForSomethingCompletelyDifferent:
** Their Japanese debut album had all-Japanese tracks... except for the very last line of "Gwaenchannaeyo" ("It's Alright") which was sung in Korean.
** Their third Japanese release ''Vampire'' also had one track (B-side "Love Bubble") sung entirely in Korean.

** Members unabashedly admit to feeling very attracted to Minjoo, Sakura, and Wonyoung's visuals.
** In terms of coolness, most members prefer [[SmashSisters Yena and Yujin]] who both have similar sporty hobbies and quirky humor.

** This seems to have improved considerably as of 2020: the Japanese members are comfortable enough in their Korean that they can [[https://www.youtube.com/watch?v=J21mJywMefM carry full conversations in Vlive]] and even [[https://youtu.be/sAPwXwPdnOs?t=857 sound like natives]], while the Korean members can now [[https://www.youtube.com/watch?v=MzGCoEfsYxg pronounce/enunciate Japanese syllables more clearly]].

* SomethingAboutARose: Their debut title track, "La vie en Rose" not only references the red flower in its title but also in its lyrics and choreography. IZ*ONE's live performances in general also often incorporate a generous amount of rose petals, flower imagery in the backdrop, and other props that evoke a floral garden motif.

'''IZ*ONE''' [[note]] pronounced as “eyes one” [[/note]] is a GirlGroup formed from the show ''Series/Produce48'', where 96 participants competed to be a part of the final twelve that would get to debut.

As IZ*ONE is a collaborative project between both South Korean and Japanese agencies and make both Korean and Japanese music, they can be considered as both a [[KoreanPopMusic K-pop]] and a [[JapanesePopMusic J-pop]] group. The group officially debuted in Korea on October 29, 2018, with the release of their album COLOR*IZ (title track ‘La Vie en Rose’) and had their Japanese debut with the album and title track ‘Suki to Iwasetai’ on February 6, 2019. Their first full Korean album, entitled ''BLOOM*IZ'', was released in February 17, 2020 (initially planned for release in November 2019 but delayed due to a series of Produce-related scandals) to critical acclaim. Their first full Japanese album, entitled ''TWELVE'', compiles the title tracks of their previous Japanese comebacks alongside new songs and is planned to be released in October 21, 2020.

Other than their numerous variety and reality show appearances, IZ*ONE has a regular vlogging/behind-the-scenes series called '''ENOZI''' [[note]]pronounced as "energy"[[/note]] '''Cam''', [[https://www.youtube.com/playlist?list=PLU5NFMWc0k7lLHDm5H_WSzm8dlEfB4x9C available with subtitles on Youtube]].

Their concert tour, ''Eyes On Me'', received a documentary film entitled ''[[BigDamnMovie Eyes on Me: The Movie]]'' that was originally scheduled for a release on November 15, 2019 to coincide with the release of BLOOM*IZ, but both were delayed to early/mid-2020. Due to the COVID-19 pandemic, EOM: The Movie's release date was moved to June 10, 2020 where it was shown in Korean cinemas [[note]]At the time of the movie's release, the infection curve was relatively low and well-contained in Korea that going out in public was already allowed even with limited seats in public venues like cinemas[[/note]]. The movie will be released in other countries at later dates once quarantine protocols have become more lenient.

On March 10, 2021, Mnet announced the end of the project following the original stipulations of the contract the members on April 29, 2021. This news was published in the wake of the announcement of IZ*ONE's second online concert entitled ''ONE, The Story'' held for two days on March 13 to 14, 2021 through Interpark as well. However, it was also revealed on the final day of the second concert that it would be the [[TheFellowshipHasEnded last day]] of the girls' official activities as twelve members together. Hence, all succeeding releases from the group and its members until April 29th were confirmed to have been pre-recorded or booked prior to Mnet's announcement.

[[folder: Tropes that apply to IZ*ONE as a group and as individual members:]]

** ''D-D-Dance'' (KR) - released on January 26, 2021 (promotional single for the UNIVERSE mobile application)

** ''Rise'' (original by Jonas Blue feat. Jack & Jack) - released March 19, 2019
** ''3!4!'' (original by Roo'ra) - released digitally March 26, 2021 (on Rewind : Blossom [[note]]a classic songs remake album featuring various artists[[/note]])

** Yena: [[AnimalMotif Duck]], Yejulia[[note]]A joke about her "Western" name when [[https://twitter.com/archivejoyuri/status/1163409578584924162 they went to LA]][[/note]]

** Hitomi: [[TheCutie Hii-chan]], [[TheOjou Hii=sama]], Tomi [[note]]Koreans tend to adopt the last two syllables of a name with multiple phonetics[[/note]], Peach [[note]]Because of her [[https://4.bp.blogspot.com/-83z3mNV2WVY/W2wzo4GtrfI/AAAAAAAALNg/CJ4-euao18oLXTqIjr-kKYheHw0iz0d7gCLcBGAs/s1600/77a730012c9297e93a0e7dca5833f6bc.jpg resemblance]] to Apeach, a LINE mascot [[/note]], Hong Dahee [[note]]A "Korean-ization" of her name, often jokingly used to refer to her more "mature" appearances[[/note]]

** Yuri has been compared to a beagle or a hamster (for her [[GenkiGirl lively reactions]])

* OnlySaneMan: [[WiseBeyondTheirYears Hitomi]] who is quiet, mature, and is considered the only braincell holder[[note]][[https://youtu.be/mq7_xBSh4Ac Until she isn't]][[/note]] of the group. She was elected as the [[VitriolicBestBuds 01s']] leader because she's the only one level-headed enough to reign them in.
* OnlySixFaces: Yuri, Yena, and Chaewon are often said to look so alike, even some of the other members can't tell them apart. Steadily being [[AvertedTrope averted]] as they've adapted more different hairstyles / hair colors and outfit choices over time.

* SoLongSuckers: Hitomi's [[https://twitter.com/hitomiiiisocute/status/1264337341247709185 farewell video]] to an [=AKB48=] Team 8 show where she was a regular is hilariously savage.
--> I'll be going to this very big place called Korea. Do your very best there in the little corner of Chiba!
** For context, the episode was supposed to be a heartwarming send-off by her fellow Team 8 members but (as expected of a variety show) they only ended up showing off embarrassing pictures and largely irrelevant stories of her. Less than ten minutes before the episode ends, it turns out that the staff prepared a video of Hitomi giving her reply, to the others' shock. Since then, the "little corner of Chiba" comment has become a RunningGag in the show (which is already SelfDeprecating about its low budget from the very start anyway).
---> [[Music/AKB48 Oda Erina]]: Please return my [[SarcasmMode sentimental feelings]]!
* SpellMyNameWithAnS: Minjoo’s name is commonly spelled as ‘Minju’, as seen on the ‘1000%’ performance on Series/Produce48 and her microphone on Show! Music Core, due to the romanization of Hangul. Minjoo herself spells it as ‘Minjoo’ and her pre-debut works list her name as such.
* SurprisinglyGoodEnglish: Wonyoung surprised many international fans with how fluent her English pronunciation sounded, especially in [[https://www.youtube.com/watch?v=8TKSnVSu5h4 this clip]]. She later stated on ''Problematic Men'' that she went to an English-based international kindergarten, but doesn't know English that well.
** Yujin, the honorary emcee of the group, also has [[https://twitter.com/radiant_YUJIN/status/1119647336966180864 decent English pronunciation]], but she admits that she's better at enunciating than ''comprehending'' the language.

[[folder: Tropes in IZ*ONE CHU and other notable variety appearances/VLIVE]]

--> '''(when asked about other members' odd/annoying habits) Hitomi''': Eunbi unnie is weird... she sends a lot of senseless pictures on our group chat, and then she goes around the dorm yelling "IZ*ONE!" so randomly.
* BigEater: All 12 members are highly motivated by food more than any other type of reward, and they're not above [[FoodAsBribe bending the rules]] to obtain their glutton-sating goodies. Examples of their TrademarkFavoriteFood include [[ExtremeOmnivore beef, seafoods, tteokbokki, malatang, fried chicken, salads, and anything with cheese]] in it. [[note]]Although they also make it a point to regularly remind viewers/fans that they ''do'' go on diets regularly, but their appetites are also good for their age.[[/note]]
** The biggest offenders are usually Hyewon and Eunbi (for desserts) and Yujin and Wonyoung (though [[JustifiedTrope justified]] given that they're the youngest and are still growing kids).
** A producer on Eat-Ting Trip revealed that Wonyoung happily ate the most food portions during the Season 2 taping even when the cameras weren't rolling anymore.
* BrainsAndBrawn: The two maknaes Wonyoung and Yujin, whenever paired together, are often promoted as this: in spite of her young age and relatively early entry into showbiz, [[ChildProdigy Wonyoung]] often boasted high grades and test scores as well as active leadership positions in school. [[HotBlooded Yujin]], on the other hand, was often teased by the other members (led by [[VitriolicBestBuds Yena and Yuri]]) for having poor test scores and only boasting school awards related to sports and extracurricular activities during IZ*ONE CHU seasons 1 and 2.
** [[AvertedTrope Averted]] firmly in RealLife, however, as Wonyoung has been known for being the only member to play at the pitching event in ISAC whereas Yujin flawlessly aced her high school graduation exam ''[[UpToEleven in the midst of Oneiric Diary promotions and TWELVE preparations]]''. [[LampshadeHanging Lampshaded]] by Eunbi and the other older members who say that Yujin is [[SmarterThanYouLook smarter than she lets people on]], saying that [[GenkiGirl she]] does most of the [[TheCharmer impromptu emcee]] [[TheFace duties for a reason]].
** Downplayed example with [[GamerChick Sakura]] and [[DancingRoyalty Chaeyeon]]: Sakura's a homebody who runs a Youtube gaming channel and hates exercising and playing sports (except swimming, apparently) whereas Chaeyeon's a dancer-choreographer who isn't too interested in playing video games unlike the other members.

* CuteButCacophonic: ''[[https://www.youtube.com/watch?v=nlBETVNWFCI&t=524s It's almost like a trademark of theirs]]''. The most recent and most notable instance was when they were invited to host a Liev [[note]] A special format of Vlive set up like an ASMR session meant to lull viewers into relaxing and/or falling asleep; it's been notable for lulling ''even the idols themselves'' into sleeping (e.g. SNSD, Red Velvet)[[/note]] and [[https://www.youtube.com/watch?v=eRMgvYWmkiI immediately turned it into their personal playground]] [[EpicFail within minutes]] [[SugarWiki/FunnyMoments of entering the set]].
* DoesNotLikeSpam: Some of the members appear to have an intense dislike for anything mint-chocolate flavored, much to the chagrin of [[TrademarkFavoriteFood Nako, Chaewon, and Wonyoung]]. Others argue (playfully) about their dislike for [[ArsonMurderAndJaywalking matcha and pineapples on pizza]].
* GamerChick: A lot of the members enjoy playing games, but the most famous one is Sakura who has maintained a Youtube gaming channel since her Music/HKT48 days (though it's been updated less often now due to their busy schedules). She [[GadgeteerGenius built her own gaming PC setup]] in their dorms that's affectionately referred to as their "PC bang" (the Korean equivalent of a manga cafe or Internet cafe) and hosts a corner in her solo radio show exclusively to talk about video games like [[VideoGame/AnimalCrossingNewHorizons Animal Crossing]].
** The '99 liners Yena and Hyewon are also noted to be avid gamers who are known to play Animal Crossing and [[VideoGame/MarioParty Mario Party]] on the Switch and horror games [[note]] though not explicitly named due to copyright reasons, eagle-eyed fans identified the game they were playing in IZ*ONE CHU as VideoGame/{{Outlast}} [[/note]] on the Playstation 4.
** Yujin also enjoys Nintendo Switch games, mostly ''VideoGame/JustDance'' with Yena and ''VideoGame/RingFitAdventure''.
** Nako and Chaewon are known for enjoying [[VideoGame/PlayerUnknownsBattlegrounds PUBG]] even on VLIVE.
** Apparently Yuri as well, as Nako relates a story of how she [[LikeADuckTakesToWater easily beat the latter's record in Kart Rider]] despite having only played the game in less than week while Nako has been playing for months.
** [[CoolBigSis Eunbi]], who despite being a beginner, enjoys playing Kart Rider and other mobile games with her members.
** Their skills have finally been put to use in the latest ISAC e-Sports competition as two teams represented IZ*ONE in the PUBG and Kart Rider events. [[note]]Sakura, Hyewon, Nako, and Chaewon for PUBG; Eunbi, Yena, and Yuri in Kart Rider[[/note]]
* LikeAnOldMarriedCouple:
** The OddFriendship dynamic between the [[TheGadfly playful]], [[DancingRoyalty physically active]] Chaeyeon and the [[NoSocialSkills reticent]], [[GamerChick athletically-challenged]] Sakura borders on PseudoRomanticFriendship since their Produce 48 days, and is still going strong. They're often likened to a [[ShipTease pair of newlyweds]] by fans (and even by [[EveryoneCanSeeIt their own members]]) and are obviously most comfortable being with each other when compared to being paired with other members. [[note]]When the girls moved dorms as of 2020, the two have become roommates who often give each other massages (to manage body pain after rehearsals), practice together, wear matching pajamas, and cook dinner together.[[/note]]
** PlayedStraight with [[https://www.youtube.com/watch?v=_0tN6mW20Uo Yuri and Yena]], who are often paired together in activities and argue/tease other a lot but ultimately show great chemistry and affection for each other (just... [[{{Tsundere}} maybe not publicly]]).

* SavvyGuyEnergeticGirl: Same-gender friendship example with Yuri and Yena. Despite being [[CuddleBug very affectionate]], [[CountryMouse Yuri]] is relatively calm and well-put when contrasted with the [[HatesBeingTouched physically distant]] yet [[LargeHam loud]] and childish Yena.
** That being said, it's a [[DownplayedTrope downplayed]] example as Yuri can [[BrattyHalfPint sass and mess with]] the other members (e.g. Minjoo and Nako) when she's in a playful mood.
* SleepsWithBothEyesOpen: Sakura’s bad sleeping habit, as exposed by the members on the first episode of IZ*ONE CHU. As of 2020, it appears that she ''still'' hasn't gotten over this habit as Nako keeps photos of Sakura sleeping like this on her phone and Sakura herself jokes about having to dress up as Sleeping Beauty [[IronyAsSheIsCast despite not being a beauty while sleeping at all]].

* TeamMom:
** [[TheLeader Eunbi]]. [[NumberTwo Chaeyeon]] as well despite only being the fifth eldest, she commonly acts motherlike to the other members. On IZ*ONE CHU, she was affectionately called the mom of the second dorm.
** Eunbi once revealed on a radio show interview that if she weren't the leader of IZ*ONE, the designated TeamMom would be Chaeyeon and TeamDad would be Sakura... to which the hosts joked that Eunbi would be the grandma.

* TotallyRadical: [[TheLeader Eunbi]] who was [[ChristmasCake born in 1995]] shows mild signs of this. She makes a lot of jokes and references that the younger kids don't understand, and members make it no secret about teasing her with her age or her attempts to seem younger.
--> '''(during a Vlive session with Minjoo) Eunbi''': What does "boomer Eunbi" mean?
--> '''(after being tasked to [[ItMakesSenseInContext act out a drunk scene]] for a variety show) Other members''': Oh, this'll be good! Eunbi unnie's probably the only one out of us [[InnocentlyInsensitive who's already experienced getting completely wasted]]!
* TrademarkFavoriteFood: A given for a group of 12 [[BigEater growing kids]]. While each member has a known preference (e.g. Nako ''loves'' ice cream and would eat 100 pints if given the chance, Sakura eats dumpling ramyeon on an almost-daily basis, Yujin cannot live without tteokbokki, etc.), their go-to foods are basically the heavy ones like grilled beef and seafoods.
** As revealed on Knowing Brothers and various fansigns, each member has a very specific and [[https://twitter.com/vocalistbyul/status/1124688627714277376 particular favorite]] [[https://www.reddit.com/r/iZone/comments/cwf70x/izone_gong_cha_orders/ milk tea]] flavor that [[BeleagueredAssistant their managers are often left flustered and end up mixing/messing up the orders]] so [[PhotographicMemory Hyewon]] does the ordering in their stead.

* VitriolicBestBuds: Yena and Sakura who are treated as the group's [[WesternAnimation/TomAndJerry Tom and Jerry]] are often trying to provoke the other with constant pestering and pranking. The '01 liners (Minjoo, Nako, Hitomi, and Yuri) also share a similar dynamic, especially [[StraightManAndWiseGuy Minjoo and Yuri]] who bicker a lot on- and off-camera (except for Hitomi who, by virtue of being the most mature enough to break up their fights, became their unofficial leader).

** Yujin the large puppy.

* TheStoic: [[TheCutie Hitomi]], partly due to the language barrier and partly due to her relatively [[TheQuietOne introverted nature]]. [[BewareTheQuietOnes Doesn't take her]] [[NotSoStoic for a pushover, though]].

** Yujin: Yudings/Yudaeng/[[https://www.youtube.com/watch?v=fE7V1w4cPNY Yutriever]] [[note]]A portmanteau of "Yujin" and "daengdaeng" (Korean for "puppy") due to constant comparisons between her and [[https://youtu.be/EHf5OH6XDcw?t=144 large, hyperactive (and hungry!) dogs]] [[/note]], [[AffectionateNickname Zini]] / [[SpellMyNameWithAnS Jinnie]] / [[FanNickname Jinniegayo]] [[note]]The last one being a portmanteau of her nickname and Inkigayo, the show which she currently emcees for as of February 2021.[[/note]]

** Chaeyeon's admirers call her [[FanNickname Feather]] as her nickname and therefore her representative animal is typically some kind of bird, symbolizing her grace and free-spirited personality.

* OnlySixFaces: Yuri, Yena, and Chaewon are often said to look so alike, even some of the other members can't tell them apart. Because of this, they've been called the [[FanNickname Joyuriz]] due to most of their similarities being owed to Yuri herself. Steadily being [[AvertedTrope averted]] as they've adapted more different hairstyles / hair colors and outfit choices over time.

*** [[FanNickname 3Won]] [[note]]Hye'''won''', Chae'''won''', and '''Won'''young[[/note]] performed Orange Caramel's "Catallena"
*** [[FanNickname 01z]] [[note]]Minjoo, Nako, Hitomi, and Yuri - aka the members born in 2001[[/note]] performed Park Jiyoon's "[[StealthPun Coming of Age Ceremony]]".
*** [[FanNickname Kkubi]] [[note]]Sakura and Eunbi[[/note]] performed [[Music/RedVelvet Red Velvet - Irene and Seulgi's]] "[[AscendedFangirl Monster]]".
*** [[FanNickname Ace Line]] [[note]]Chaeyeon, Yena, and Yujin[[/note]] performed Kehlani's "[[Film/SuicideSquad Gangsta]]".

** The entirety of the "Coming of Age Ceremony" unit stage in ''Oneiric Theater'' revolved around the idea of the [[FanNickname 01z]] kids doing a mature concept as a [[SheIsAllGrownUp rite passage of adulthood]].

** Most of the cover performances in "ONE, The Story" Day 1 count as this, including Eunbi's "Señorita", Hitomi's "All Hands On Deck", and [[FanNickname MinKkuChaen]]'s "Full Moon" stages.

* RefugeInAudacity: ''Oh, yes'', combining 12 unique personalities can do that to a group. Nothing says "IZ*ONE" like a session with blatant cheating or negotiating during (non-serious) competitive activities or rule-breaking and spoiler-dropping at nearly every possible moment. Their streams are often notorious for being difficult to edit due to the amount of rules which they unintentionally (and sometimes intentionally) violate, ''to the point that they're the shining example of what'' '''not''' ''[[https://lh3.googleusercontent.com/gBWpMrfz3MPyqIZGTrJFuPZOHNWMQ7_13_-4k4lax1T5Qm2Xm6c1pBYK1izndadQ8DaITnc3JFU1I5aTTCEZdUWJlmC6nmjZkA=w1200-h630-rj-pp-e365 to do during Vlive streaming!]]''
** Even live shows are not exempt from this: on their Oneiric Diary comeback showcase, they were [[https://www.reddit.com/r/iZone/comments/h7dfry/200612_izone_will_being_doing_a_escape_room_for/ supposed to undergo an escape room]], but IZ*ONE being [[FanNickname IZ*MESS]], they manage to fluster the staff [[spoiler: by [[CuttingTheKnot breaking the props to skip over an entire puzzle segment]] and [[SugarWiki/FunnyMoments would have broken the final room as well had Sakura not been a quick thinker]].]]
