Nyathoggoth

The Nyathoggoth was a vampiric creature with a liquid form.

Devastating worlds in its need for blood, the Nyathoggoth was eventually captured and imprisoned in a spaceship. It was programmed to fly into a black hole, but there was a malfunction and it crashed on Earth in the early 20th century.

The Forge sent a retrieval team led by Nimrod to collect the technology from the ship, calling the operation Project Valhalla. The Nyathoggoth tricked Nimrod into deactivating the force field containing it. Cassie Schofield allowed it to feed on her, infecting it with the Twilight virus, which weakened the creature. Nimrod managed to interface with the ship's computer and activate its self-destruct protocols, and turn the force field back on to contain the explosion.

The Nyathoggoth took control of Cassie and had her fight Nimrod, but threw off the influence long enough to stab herself instead of him. Communicating through her, the Nyathoggoth said it would give Nimrod great power if they worked together, but Nimrod would not accept. The ship was destroyed, and the Nyathoggoth along with it.
