On April 3, 2008, SM Entertainment released the official name of the subgroup, Super Junior-M, with "M" representing the word "Mandarin," expressing the subgroup's ambition to become successful in the Chinese music market not limited to only China. The "M" can also represent a list of other aspects, such as the first letter of their debut album, Me, and also "mi" (Chinese: 迷), which denotes to "charismatic" as well as "fan" in Mandarin, the latter meaning referring to their desire to connect closer with fans.    

4. Suju K.R.Y

Super Junior-K.R.Y, established in November 2006, is a trio formed by Kyuhyun, Ryeowook, and Yesung which makes up K.R.Y.in the title of the group. The company discovered that these three members developed a particular personal and subsequent fan-base that was separate from the rest of the group, and how they also had similar musical qualities. They therefore grouped these three members together to perform particular songs to target a more mature audience. Being amongst the most vocally powerful members of the group, Super Junior-K.R.Y are credited to singing mournful, R&B-style ballads, a style that has proven very popular in recent years although stagnation in the style's development is causing it to lose its once fresh evocative power.

Super Junior-K.R.Y's first official performance was on November 5, 2006 on KBS's Music Bank, performing "The One I Love (한 사람만을)."They have participated in the original soundtrack of the tvN drama Hyena with a total of three tracks, including the main theme. The trio also contributed tracks in two additional original soundtracks, one track in both the soundtracks of Snow Flower and Billy Jean Look at Me. Unlike Super Junior's other sub-units, Super Junior-K.R.Y has not officially released a single or album, and only participated in collaboration albums and original soundtracks. However, a new album is expected from K.R.Y in the future.

On 1 August 2010, Super Junior-K.R.Y had a concert of their very own in Japan, with Donghae and Sungmin as guests
