Sadu-Hem was one of the 369 Ogdru Hem, the children of the Ogdru Jahad.


Imprisoned on Earth so that the Ogdru Jahad would "always have a foothold in the world from which they were banished", Sadu-Hem was discovered by Rasputin in the Gorinium temple at the top of the Arctic circle. Rasputin remained in a trance near the statue until the arrival of Professor Trevor Bruttenholm and the Cavendish exploration party. The newly-awakened Rasputin and Sadu-Hem devoured most of Bruttenholm's exploration party. Bruttenholm was allowed, under heavy psychological compulsion, to return to America, where Rasputin and Sadu-Hem installed themselves below Cavendish Hall. Physically, Sadu-Hem appeared as a gruesome mass of tentacles and snapping claws, with a cluster of eyes and feelers serving as its head. Sadu-Hem was to act as the conduit between Rasputin and the Ogdru Jahad, but was destroyed in a massive fire.

Although Sadu-Hem was apparently destroyed, a small piece of him, a fungal spore, was discovered in the Cavendish Hall ruins over a decade later. The specimen of fungus was preserved in a New Jersey lab until Sadu-Hem grew strong enough to absorb a human form and escape. Fleeing to Crab Point, Michigan, Sadu-Hem converted an entire town into vicious Frog Monsters before he was again immolated.
