Semkhet was one of the totems of the Ra-Tet. He appeared as a skinless sabertooth cat. Semkhet was one of the two dark beings of the Ra-Tet, symbolizing sunset and the coming of night. When the Beast came after Semkhet, he shredded the totem's body. Semkhet was a more or less evil being and he was known to associate with Mesektet. Rhinehardt's Compendium depicted Semkhet as a companion to Mesektet. Gunn likened Semkhet to being a pet or a "puddy-tat to the world's scariest six year old".
Semkhet occupied a dense cave system located on the outer mountain regions of Los Angeles.
