From Dragon Ball Encyclopedia, the ''Dragon Ball'' wiki
Kinkaku (金閣, Kinkaku; FUNimation "Terror"; Literally meaning "Gold Horn") is a Human.
Kinkaku and his comrade, Plague, terrorized Chao's Village with the Gourd of Mist until they were defeated by Son Goku "Terror and Plague". Kinkaku was shown to be the leader of the duo, and he even told Plague to stand down stating that he was no match for Goku. Although Terror was able to put up a better fight, he was still outclassed by Goku and forced to use the Gourd of Mist to trap him inside it.
Eventually, Kinkaku was trapped inside the Gourd of Mist alongside Plague after failing to say his name as many times as it was called. He was later seen with Plague farming in the village and being threatened by the village people.
