but technically haha debuted solo as an underground artist and as a member of zkiri later and zkiri disbanded and turbo disbanded and are only active for special projects like anniversary .Hi there! You are correct, no form is needed since they debuted as singers. However, since both are a part of two different duos/groups you have to include the whole groups and the other members (For Haha it’s RPG group badge, Haha and Skull, for Jong Kook it’s Turbo and the other two members) in your badge threads.
Edit : i now understand haha since he redebuted as RGP and havent had any solo since but i would really appreciate if kook could be categorized as solo . Also another Question if i redue hahas thread and dont get any supporters or keepers for group/skull does this mean i can get hahas badge because tbh im confused now and no wants a turbo or rgp badges
