Fusion-When two people are nearly equal in power they can be able to fuse together and form one extremely strong being. To fuse both people must be doing the fushion dance correctly, to become one. There are three new fused characters called Gogeta, Vegetto and Gotenks. Gogeta is the form of Goku and Vegeta, Vegetto is the form of Goku and Vegeta fused with the Ptara earings was intended for Gohan's use but dropped them and Vegeta caught them and wore them. Gotenks is the form of Goten and Chibi Trunks. When they fused they did the dance correctly but got absorbed by Buu because they had no fighting experience. Fusion Dance-when the fusion dance is done correctly two people fuse together and form one strong being. It only lasts for about for about 30 minutes and after they split they can't fuse again for another hour, When Vegeta messes up the fusion dance he and Goku form Fat Gogeta. With the Potara aerrings ( used by Goku and Vegeta ) they can fuse for a much longer period of time without splitting apart.
