Kim Dae Sung, formerly known as ACE, is a South Korean singer, dancer and former member of MASC (마스크) and of the underground rap crew Rassay Sunz.

He debuted as an actor in 2014 with a role in the SBS drama "One Warm Word Behind" and debuted as a singer in August 2016 as MASC's rapper with their first EP, "Strange".

However, he became involved in a major controversy when he physically assaulted fellow member Chibin, who months later posted images on social media detailing the incident. Both were interviewed separately, and the prosecutors acknowledged the unilateral assault against Chibin. He apologized, but the agency, J Planet Entertainment (제이플래닛엔터테인먼트, formerly known as JJ Holic Media and Isam Media), decided that both members should leave the group.

At the end of the month, he took full responsibility for his actions, left MASC and ended his contract with the company. Despite rumors of a possible return to acting, he seems to be completely out of the entertainment industry now.
