* BreakupBreakout: CL is way more known than the rest of the members in the group as a solo artist.
* DevelopmentHell: Their second album, ''Crush,'' was stuck in this. First reports gave it a Summer 2012 release, later reports had the album scheduled for release in April 2013. It was finally released at the end of February 2014, almost two years after it was originally announced.
* DyeHard:
** CL is usually a blonde, except for their [[http://feedyaluvkorean.files.wordpress.com/2009/07/20090630_2ne1_1.jpg I Don't Care]] and [[http://4.bp.blogspot.com/_-EbMoCxlXNg/TPnCgD34IuI/AAAAAAAABHg/ie6m7udtknM/s1600/cl_02_1280.jpg Fire]] [=MVs=], where she was a brunette. She was brunette [[http://25.media.tumblr.com/1dd0d8520032de9395c00d6bd002770e/tumblr_mwlg5fPR6K1r49sxvo3_250.jpg again]] for "Missing You", but went back to blonde for "Happy" and "Come Back Home".
** The other members dye their hair too; Dara is usually some shade of brown, except for the "Falling In Love" and "Missing You" videos, where she's a blonde, and the promotions for "Crush", where she had [[http://i1.wp.com/ygunited.com/wp-content/uploads/2014/02/blue-dara-crush.png?fit=650%2C650 blue]] hair. Bom has either brown or red hair, while Minzy... she has tried almost everything, including purple and (even if it was only a wig) pink.
* WhatCouldHaveBeen:
** Minzy was supposed to debut as a duo with singer Maydoni - and anyone who's seen how Maydoni can [[https://www.youtube.com/watch?v=MPSiBFLcZ_U sing]]/[[https://www.youtube.com/watch?v=49EkH-LpszU dance]] knows this would have been ''epic''! Unfortunately, Maydoni chose to leave YG after her sister Yenny was dropped as a trainee.
** [=RaNia=] member [[http://www.jpopasia.com/i1/news/2/6335-sqvde5g4i2.jpg Jooyi]] was supposed to debut as a member of 2NE1 (allegedly as Maydoni's replacement), but chose not to, debuting as the main vocalist in [=RaNia=]. She could have [[https://www.youtube.com/watch?v=xaYQwOSaSe4 easily]] rivaled Bom in terms of vocals!
** Minzy revealed in a February 2021 interview that Music/{{Blackpink's As If It's Your Last was originally written for 2NE1, (confirming a long-standing rumor) and that the song's original title was "Blame It On Your Love".
