Kim Tae Dong is a South Korean singer, dancer, actor, former member of GIDONGDAE and current member of OMEGA X. He graduated from Gyeonggi Tourism High School and later attended the Practical Dance program at Myongji University but dropped out. Before debuting, he used to be a trainee at MAJOR9 (formerly known as The Vibe Entertainment) but decided to leave the agency due to mistreatment. He joined 2Y Entertainment in early 2018 and was set to debut as part of GIDONGDAE in mid-2020. In June 2020, they released a pre-debut single titled "Party Like This" but the COVID-19 pandemic and the financial issues of the agency, ended up disbanding the group in January 2021 without having officially debuted. After switching agencies, he debuted in July 2021 as a member of OMEGA X with their first single album, "Vamos". However, in October 2022, a video of the CEO of OMEGA X's label (Spire Entertainment) abusing him and his group members came to light. The members filed a lawsuit against their company to cancel their exclusive contracts and to file for the trademark of their group name. In January 2023, OMEGA X won the lawsuit and officially ended their contract with the agency. This was finally made official on May 8, 2023. The group is has been represented by IPQ since July 2023.
