C AllStar is a Hong Kong Cantopop boy band formed through a singing contest Star Hunt (星投大戰) held by Kingdom C in 2009.

The group consists of four members: King Wu, Kenny Chan, Andy Leung, and Jase Ho.

In 2009, Hong Kong music label Kingdom C held a singing contest Star Hunt (星投大戰).

The album adopted different music styles, including trance, bossa nova, rhythm and blues, etc.

[12] King Wu explained that they feel like the life in the group is somewhat disheartened and they would like to pursue solo activities so that members can evolve in more specific fields.

[13] In the light of anti-extradition bill protests, the group temporarily reunited and released "You Are Not Alone" (沒有剩你一個) in July 2019, noting "we are all together in the storm".

[21] In January 2022, local media reported that ten Canto-pop singers and groups had been put on a blacklist of government-funded broadcaster RTHK, with radio DJs having been ordered not to play their songs.
