## Trivia

* IZ\*ONE currently has a total of 32 unique units.
	+ There are 37 songs listed on this page. However, 5 of these songs used units that have been used before.
* The following units have been repeated:
	+ Rumor (repeated for Mirotic) - Yena, Eunbi, Chaewon. Minju, Chaeyeon

* Currently, the largest units are SO CURIOUS (BLOOM\*IZ) and AYAYAYA (BLOOM\*IZ), each with 9 members.
	+ Coincidentally, Yuri, Yujin, Nako, Chaewon, Minju and Chaeyeon are part of both of these units.
		- Furthermore, none of the mentioned members are a part of the DREAMLIKE unit (also on the BLOOM\*IZ album, likely done to balance out the number of units each member was a part of).
	+ These units were originally 6 membered-units for Eyes on Me, however, 3 additional members were added to each unit for BLOOM\*IZ, making these units 9-membered.
	+ Technically, Hitsuzensei has the largest unit overall with 24 members. However, of these 24 members, 6 of them were IZ\*ONE members, while the other 18 members are members of AKB48, SKE48, HKT48, Nogizaka46 and Keyakizaka46.
* Gokigen Sayonara and Neko ni Naritai are 7-membered and 5-membered unit groups on their 1st Japanese single Suki to Iwasetai. However, they were re-released in Korean on their 2nd Korean mini album HEART\*IZ as 12-membered group songs.
* Rumor was performed by a unit only for the COLOR\*IZ Debut Showcon, however, they have since performed the song as a 12-membered full group song.
* Currently, the smallest units are Dance wo Omoidasu Made, Human Love, Fukigen Lucy,  Love Will Show You Everything and Monster each with 2 members.

	+ 17 songs - Sakura, Yuri
	+ 15 songs - Wonyoung, Yena, Nako, Chaewon
	+ 14 songs - Yujin, Eunbi, Hitomi, Minju, Chaeyeon
	+ 12 songs - Hyewon
	+ Hyewon is the only member who hasn't participated in a unit song outside of regular IZ\*ONE promotions (musical releases, concerts, showcases).
		- Hyewon, alongside Yena, Yujin and Chaeyeon are the only members who haven't participated in a unit song outside of regular IZ\*ONE Japanese promotions.
* BLOOM\*IZ currently has the most number of units, having 6 units.
	+ BLOOM\*IZ also has each member participate in 3 units, the most of any release/performance.
* While units have been included in all of their Japanese releases, BLOOM\*IZ is currently the only Korean release to include units.
* COLOR\*IZ , HEART\*IZ and Oneiric Diary are IZ\*ONE's only releases to date to not include units.
* Excluding To Reach You (covered by the full group), all of the songs on the 30 Girls 6 Concepts EP have been performed by an IZ\*ONE unit at one point.
	+ Interestingly, Rollin' Rollin' and 1000% weren't performed by IZ\*ONE members who originally performed the song on Produce 48.
		- Wonyoung and Hitomi aren't in the Rollin' Rollin' unit, and Minju and Chaeyeon aren't in the 1000% unit, despite them being the original performers of the songs.
	+ Chaeyeon, who was booted from her initial song on this EP (I AM) was able to perform this song as an IZ\*ONE member in a unit.
