Necromon 26

Gristle: invented by a fast food chain, these piglike zombies are programmed to be excellent butchers and can be easily created from scraps of spoiled meat. Though intelligent and well-meaning, they cannot differentiate right from wrong and will freely butcher any living thing (or fellow zombie) within reach, expecting nothing but praise for a job well done...sometimes from a finely diced pile of their own master.

Madcap: one of the only monsters originally created by another monster, the Madcap are descended from a similar but far larger and more powerful creature that was ultimately destroyed by its own spawn. Constantly giggling from both mouths, there seems to be nothing they do not find uproariously funny. They are able to implant false memories in the minds of other sentient beings, and delight in driving humans to commit atrocious crimes for reasons that never existed.

Zeze (Human/bloodfly fusion) : Zeze are one of the few insectoids light enough to actually fly, and can reproduce at a terrifying rate. They are surrounded by a numbing chemical miasma, which makes their attacks painless and imperceptible even as they gouge wide, round holes in the flesh of their prey to messily lap up blood.

Estrel (Vampire-chicken) : a type of vampire, the Estrel feeds on blood through a prehensile digestive system that can extend up to fifty feet from its tiny body. It sometimes lives parasitically in the bodies of humanoid zombies, creating a nest of flesh and bone in their abdominal cavity.

Korpus: defective monster. Encased in a tangled ball of random, barely-living appendages, it has an uncontrollable urge to hide in total darkness, and flies into a panic when discovered.

Progeny: vaguely related to the Endo, this monstrous creature is devoid of most internal organs, and can only survive through a strange, "backwards" parasitism in which the host, always human, is held within the monster's body to perform vital functions that it otherwise lacks. Its blood is oxygenated and circulated by the lungs and heart of its unconcious victim, its food processed by a captive digestive tract, and some believe that its mind operates on instinct alone until it finds a suitable human "core". Former hosts tell tales of a utopian dream-world so wondrous that some never wish to be rescued.
