Grim Reaper

Grim Mirror
Trigger: Alcohol was your poison of choice, and it did a damn fine job. Spouse left you, lost your job, out on the streets, rendered homeless. That wasn’t what got you. Nor was it when you got beat up by some kids who thought it was fun to bully the homeless. Being treated like human refuse didn’t do you in. What got you was when an attorney for your spouse tracked you down, with the help of your brother. For some brief moment, you were hopeful - then they handed you a document, demanding you pay back child support. Your brother tears into you, calling you lazy, worthless, a pathetic piece of shit and a disgrace to your family. Trigger.

The parahuman can, with a full round of effort, rip a 'hole' into a parallel dimension, or close one. Closing it is interruptible. The parallel dimension they enter resembles the true one in terms of geography, locations, et cetera, but any object that isn't inert (e.g. cars) won't appear there. Paint on signs is torn; black and red paints weep instead. Graffiti is present, but always and only speaks of death, the end of days, and despair. The streets are empty of any native life. On the native side, opening a portal creates a broadly visible flare of light, sunshine peaking down through the eternal overcast for just a few minutes.

Humans trapped inside this dimension suffer gradual degradation, pain, and warping. The parahuman themselves is immune to this effect. After a day or so, humans inside the dimension finish warping into grotesque, vicious monsters (Giger/Silent Hill-esque). Animals suffer a similar effect, but with a shorter timescale proportionate to their size. These monsters will hunt down, kill, and eat, any humans or animals other than the parahuman they catch. Outside of this parallel dimension, they gradually degrade and die off. They obey the parahuman with a doglike intelligence, but will attack any human other than the parahuman who gets within around twenty feet of them.

Human-derived monsters have a base statline of 2/3/2/3/1/1/2; other mutants have lowered stats, relative to their size (large dogs tend to be 1/2/1/2/1/1/1). They have natural weapons, useful for inflicting Moderate Rends (Lesser for smaller minions). Human-derived monsters also have mutations granting other abilities; roll on the following chart when one is created. These abilities only manifest after the minion has been a monster for a couple days and allowed free reign inside its home dimension.

Mother
Entire internal structure is warped, turning it into an incubation chamber for maggotlike vermin that are native to the creature’s biology. It can drool or spit on command, and when it stays still for at least a minute, it does so as well. These creatures cover a 5’x5’ area, and attempt to bite or dig into the flesh of anyone they can catch. If the person is wearing shoes, it typically takes until the end of the next round for them to wriggle through holes, bite through leather, etc, to get inside. Individuals they bite suffer a -1 to Athletics and pain in their legs, until they’re removed, a full round action requiring a Dexterity check (DC 4) to perform.
Scraphound
The creature natively and passively rubs along rusted nails, broken electronics, and similar bits of metal. The end result is that it’s covered in a light coat of jagged metal. Anyone grappling it suffers a Lesser Cut, it can climb at 15’/action, and its attacks also deal the effect (but not damage) of a Lesser Cut.
Mutilated
The creature tends to bite and claw at its own flesh, wounding itself, and black blood crusts across its surface as a consequence. It gains a +1 to Guts, and it may remove a limb, which retains a life and ability to move on its own, inflicting a Lesser Rend to anyone it can grasp, and moving at 5’/round towards the nearest living thing.
Faceripper
The creature becomes irate with its own eyes, finally clawing them out and attaching them to its skin as a kind of bizarre trophy. It cannot see, but it has greatly enhanced senses elsewhere, manifesting as a +1 to all Wits rolls. It can flawlessly trace anyone it has damaged, regardless of distance, and through the path between dimensions.
