The Klathi were an intelligent humanoid species. They were skinny, with bald heads, forked tongues and pointed ears. Their spaceships used a crystalline power source.

They came to the Joebb's world and vastly improved it. However, the Klathi's help was not appreciated and they were overthrown. Caval, one of the Joebb who was friendly with the Klathi helped two of them, Danq and Yula, escape in one of their ships. They reached the vicinity of Earth during the Victorian period. A meteor storm caused them to crash, after which they were rescued and became part of a circus freak show. Danq and Yula went by the name "the Satan Twins". (COMIC: Claws of the Klathi!)
