Little is known about Hookocho, say that he is an evil alien warlord who came to Koosland to abduct its guardian, Peepers, for the purpose of absorbing his limitless power to energize his space fortress' secret weapon, designed for one purpose: to erase Dee Dee's world from the face of Imagination and use his newly enhanced powers to rule the Galaxy. However, his plans are foiled by the efforts of Dexter and Koosy. But Hookocho's ultimate demise can be contributed to Peepers, the hatred mutating him into a flesh-toned dragon and promptly stomping and killing Hookocho, just as the elven maledict is busy tormenting Dexter and Koosalagoopagoop.
- He appears in season three's episode thirteen, and is voiced by Jay Hugley.
- He is most likely a parody of effeminate male anime characters.
- His name is often misspelled "Hokochoo," but it is actually spelled "Hookocho" in the ending credits of the episode.
