Potara
First Appearance: chapter 501
Category: miscellaneous
Explanation: Ear decorations worn by Kaioshins and their attendants for generations. Despite being worn so casually, they’re actually an incredible power-up item. The Elder Kaioshin gave them to Goku as a trump card for defeating Majin Buu.
Special Characteristics: To use them, the two people who will merge simply each take one of the two earrings and put in on their left or right ear, respectively. Furthermore, after merging the power is greater than with Fusion. However, the two people will automatically merge as soon as the earrings are put on, and in principle will be unable to ever split up again, so caution is needed when handling them. The merged person will only split up when touched by the air inside Majin Buu’s body. Also, while with Fusion the post-merged clothing is the native dress of the people of Planet Metamor, when merging with the Potara not only are the two people’s bodies mixed together, but their clothing is as well. In addition, pathetically enough the East Kaioshin and his attendant Kibito merged together without knowing a thing about Potara fusion. (Daizenshuu 4, p.163)
