Greetings and salutations! Just having managed to become a member of this site after lurking for some time, I have some ideas to share that I want to make sure are worth writing and haven't been done. The ideas are fairly fleshed out in my head, but here are the general synopses:
1. Skincrawlers: Large, vaguely humanoid, leech-mouthed creatures. Reddish-white in appearance, like muscle, prefer swamps. They reproduce by tearing open a victim's chest cavity and implanting a fetal version into the wound, which consumes the contents of the victim while keeping them alive as a host. Eventually the juvenile integrates itself with the body, absorbing and replacing the host's soft tissues with its own. During this time, it influences and controls its host's actions by commandeering the spinal cord, and due to this, it consumes the actual brain last. When fully grown, the skincrawler will continue to wear the victim's skin until it falls off, imitating the victim by doing things it learned while riding around inside them; this is how it gets close to other humans to continue to reproduce. Keter class.
(I have an encounter log and containment procedures outlined as well, if this idea bears use.)
2. Acid Shower: Appears to be a standard, upright, one-head shower with a glass door. Anyone who uses it, however, is doused in what appears to be highly concentrated gastric acid anywhere from two to five minutes into the shower, digesting the victim. The glass door becomes sealed shut during this event, and cannot be broken by average human strength. After the victim is sufficiently degraded, the drain opens and consumes the remains. If discovered for its true nature, the entity vanishes, leaving claw marks, bloodied pipes, and a larger gap in the surrounding area than the shower-booth itself.
(This one is just about finished as well, but it feels like someone must have come up with it beforehand.)
Thank you all in advance for your feedback and/or suggestions! :3
