Bulchi is the fusion dance of Bulma and Chichi as well a fan-made character in the community. This happened when Goku and Vegeta fusing to Gogeta and teaches the women how to do the Metamoran Fusion. Bulchi Has Bulma's Long Dark Turquoise Blue Hair And Chi Chi's Black Hair. Personally is more upbeat and friendly but still has sassiness into her. The Metamoran Fusion dance only lasted to 30 minutes then the separate into two people and have to wait 30 minutes to go back into Bulchi.
