the first fusion ever was when 고쿠 and vegeta fusioned using the fusion dance.it was during the majjin buu saga 고쿠 and vegeta were getting beaten badly then 고쿠 remembered what piccolo had told him the fusion dance.then 고쿠 taught vegeta the fusion dance first it didnt work right because vegeta didnt have his fingers up then the 다음 time it worked but it still wasn't enough to defeat majjin buu so yhey used the potara earings and used the final kamehameha to finish him off for now.
