Tomb-Herd

The Tomb-Herd are gelatinous blobs from another dimension that possess special statues upon entering ours so that they can feed. If a statue is unavailable, they can possess a human for the same purpose.

In the RPG...

Though I wasn't a fan of the Tomb-Herd when I read the source material, I've since come to appreciated them thanks to their Call of Cthulhu entry. The Tomb-Herd have two forms. The first is their natural, insubstantial form, which is immune to all physical weaponry. Previously, fire and acid did normal damage, but the 7e Malleus Monstrorum has removed this. In this form, the possession mentioned above is determined by an opposed POW roll, which an average person has a 76% chance of losing. Even if they win, they still pass out for 3-6 rounds. Once fed, the Tomb-Herd leave their host otherwise unharmed. They also have the ability to fold space in a small region—less than 5 miles—such that the victim always returns to where they came, losing 1 Sanity point each time they do. The 7e Malleus Monstrorum has added that a trapped person can escape with an Extreme POW roll. In their second form—possessing a statue—the Tomb-Herd are harmed normally, though they do have 3 armour, and impaling weapons only do half damage.

    The 7e Malleus Monstrorum has changed many of the Tomb-Herd's stats. For a start, it has removed CON, SIZ, and DEX completely from their natural form. Being insubstantial, having no STR makes sense, but I feel like the others would still have a place with such a form. They also have no Move any more, which makes even less sense. INT and POW on both forms have the same average as before, with only their ranges changed. CON for the statue form has also had its range reduced.

In a video game...

I think the Tomb-Herd would work quite well in a video game. Not from a combat viewpoint, but from a gameplay one. Their ability to loop space could really mess with a player, especially if they didn't know why it was happening or how to escape it.

In a film...

On the flipside, I think the trait of the Tomb-Herd that would work best in a film is their possession. Having the antagonist forced to partake in their ghoulish feeding could be a truly horrific thing in the right hands. I can't remember if the protagonist from The Church in High Street was conscious during his possession, but it could be worth adapting.
