Earrings from the Dragon ball
universe that let the two
people who wear them on opposite ears
fuse after the earrings make them touch tips. The fusion was supposed to be permanent until Dragon ball super happened and it wasn't.
Goku and Vegeta used the potara earrings to become Vegito. Then, Vegito kicked the shit out of Buu-
Han until Buu-Han
ate Vegito and he defused because of Buu's stomach acids.
Goku and Vegeta fused again to anal Zamasu. They pulled off a Final
Kamehameha before they defused because the writers wanted Trunks to use the Spirit to defeat Zamasu.
Cauliflia and Kale used the potara earrings to become Kefla so they could defeat Goku until he went ultra instinct and wiped Kefla's ass.
