Dark Young of Shub-Niggurath

The Dark Young of Shub-Niggurath are large, three-legged hoofed creatures with numerous tentacles sprouting out their top. When encountered in forests, they are easily be mistaken for trees.

In the RPG...

Dark Young are one of Call of Cthulhu's more common monsters, which is surprising considering how powerful they are. They take only 1 damage from firearms, and non-physical attacks involving heat, blast, corrosion, electricity, or poison have zero effect—so no dynamite! Melee weaponry does normal damage, but who would want to get up close and personal with a creature that can attack 5 times per round with an average damage of 14!? It can also use its tentacles to grab up to four Investigators, holding them to one of its slavering mouths and draining an average of 10 STR per round (which cannot be restored). The held victim cannot escape themselves, so need others to help free them. Even with two Bonus Dice, an opposed STR roll against a Dark Young only has an 11% chance of success for an average person.

    The 7e Malleus Monstrorum has changed the rolls for the Dark Young's CON, DEX, and POW, though all averages remain the same.

In a video game...

Due to their popularity, I feel it would be sacrilegious to not include a Dark Young in a Mythos video game. However, due to their difficulty, I feel it would only work as a set-piece, where the aim is not to kill it, but just to escape alive. Not many people know this, but a Dark Young almost made it into Call of Cthulhu: Dark Corners of the Earth. It was unfortunately removed towards the end of development when they realised the game wasn't reaching its deadlines.

In a film...

I think Dark Young are unique- and scary-enough that they would absolutely work in a film. I can easily imagine the image above being a storyboard for such a film, and am saddened by the fact that it actually isn't.
