The fused form of Bulma and Chi-Chi after performing the Fusion Dance properly. She does not appear in any official Dragon Ball works, instead making her first and only appearance in the April 15th 1995 issue of Shounen Jump, in a fan fusion contest.
Given her fan-made nature, how Bulchi looks like will vary from artist to artist. The 1995 contest's design of the Metamoran vest has found some use as a 'sexier' version of the vest for female fusions in fanart.
