Gaoishi is the result of the Fusion Dance being performed by Aoishi and Goishi. The two were told about the Fusion Dance by the descendant of Goku, Singan. After much persuasion, Brouse and Singan acted out the Dance to the two brothers. The two brothers performed the dance, and succeeded in creating Gaoishi. After Abduc entered Earth's atmosphere, Aoishi and Goishi fought their father, but failed to subdue him. They then decided to transform into Gaoishi. As the fusion fought Abduc, he unlocked the Super Saiyan 1 and 2 forms, but remained unable to beat Abduc.
