Necromon 18

Mormel: built for subterranean labor and excavation, these bull-sized mutant rodents have the unusual (and accidental) trait of being completely immune to psionics. With most of their muscle mass connecting to the jaws and teeth laced with raw metal, their bite is a true force to be reckoned with. They particularly enjoy crunching skulls between their incisors, and may store them in their cheek pouches.

Venomax: fusion of human with scorpion. Though it loathes the sun, it craves the heat and is entirely fire-resistant. After paralyzing prey with its lightning-fast sting, it impales it on its larger claw.

Despire: a small but exceedingly malicious creature, the Despire is able to "reverse" the emotions of humans and other monsters, sewing irrational hatred between friends or turning the fear of its prey into deadly curiosity. It has a strong dislike of human children.

Tumor-man: the true form of this noxious zombie is hidden by a thick shell of random, overgrown flesh that it can instantaneously spread to other creatures by a single touch. Victims cannot spread the infection themselves, but fall completely under the Tumor-man's will, creating a cancerous collective of enslaved bodies. This process is pleasurable for the tumor-man, which titters and burbles contentedly while pouring noxious blight into another living body. Thankfully, these beings are too carefree and simple-minded to become a serious threat, rarely leaving whatever dank alley or sewage drain they mark as territory.

Boltbucket: these deranged "entertainment" monsters are designed to unleash completely random kill-commands (or the ocassional "prize") on a specific verbal trigger that varies from monster to monster, though the most commonly programmed trigger appears to be "hello". A single unit may house over thirty ways of causing extreme discomfort and/or death to hapless victims, from live scorpions and itching powder to "rabies darts" and miniature atomic warheads. They are capable of speech, but act senile and scatterbrained. "Execute" appears to be their favorite word, often repeated for hours at a time.

Neurosia: these completely insane constructs can generate seemingly random metal objects from inside their mysterious cubes, and are rumored to control the gateway to another plane of existence. They sooner destroy themselves by implosion than allow their boxes to be studied, and can only be created at all with the aid of a temporal distortion engine.
