Ogdru Hem

The Ogdru Hem are fictional creatures in the Hellboy universe. After awakening, the demonic Ogdru Jahad gave birth to the 369 Ogdru Hem. The Ogdru Hem are essentially weaker versions of their parents, but even so they wield unimaginable power. All of the Ogdru Hem were imprisoned by the Watchers, but many are now re-emerging, with the aid of Rasputin and other agents of the Ogdru Jahad.

Many of the Ogdru Hem are without bodies and exist, invisibly, in the air. These evil spirits are used to help raise the Ogdru Hem that have bodies (such as Katha-Hem) out of their earthly prisons.

Imprisoned on Earth so that the Ogdru Jahad would "always have a foothold in the world from which they were banished", Physically, Sadu-Hem appeared as a gruesome fungal mass of tentacles and snapping claws, with a cluster of eyes and feelers serving as its head. 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 he was awakened the arrival of Professor Trevor Bruttenholm and the Cavendish exploration party. The newly revived being devoured most of Bruttenholm's exploration party, turning the Cavendish brothers and Sven Olafssen into frog creatures. Bruttenholm was allowed, under heavy psychological compulsion, to return to America to enact Rasputin's scheme to bring Hellboy to Cavendish Hall, with Sadu-Hem installed in the underground caverns. Sadu-Hem was to act as the conduit between Rasputin and the Ogdru Jahad, but was destroyed after Abe Sapien speared Rasputin to death and Liz Sherman set the entire place on fire.

Although Sadu-Hem was apparently destroyed, a small piece of the creature was discovered in the Cavendish Hall ruins over a decade later. Director Manning had the specimen of fungus preserved in a New Jersey lab, until Sadu-Hem grew strong enough to possess a human host and escape. Fleeing to Crab Point, Michigan, Sadu-Hem converted an entire town into vicious frog monsters before he was again immolated by Liz Sherman.

At the end of the first Hellboy film, Rasputin releases from his body a giant monster simply referred to as the Behemoth, which Hellboy fights and destroys. The Behemoth's appearance is similar to Sadu-Hem.
