Even though there was only one in the original series, one other fused characters appear in Dragon Ball Z: Fusion Reborn, in Dragon Ball GT and in a What-If saga of the video game Dragon Ball Z: Budokai 2. Only one character in the manga has been seen as a result of the Fusion Dance his name is Gotenks, being a fusion of the characters Goten and Trunks. Goten and Trunks perform the Fusion Dance in Yo! Son Goku and His Friends Return!! Additionally, all end products of the Fusion Dance seem to acquire the same attire: white pants, a sash, and a vest with yellow or orange padding around the shoulders and neck. If they synchronize their dance correctly, it results with a very powerful being.
Regardless, the fused character possess mixed physical traits of their original counterparts. If the timing of the poses is off, it results in a sickly-looking fusion who is also much weaker than each fusee individually. If one character performs the dance wrong, then it will result in an obese or a skinny character who is much weaker than either fusee individually. In the series, the result of a correctly performed Fusion Dance is a superior being whose power is multiplied severalfold over that of the individual fusees.
The Fusion Dance is a short series of poses that are performed by two characters of equal power levels and roughly equal size. To correctly perform the Fusion Dance, the fusees must create a perfectly symmetrical image of one another. Goku and Piccolo demonstrating the Fusion Dance
