Night and Fog are a supervillian team who are psychotics who sort of "play" at being husband and wife but are really ... something something (I'm not sure--they seemed personable enough if not exactly functional during their interlude). They compliment each other:
Fog is the "simpler" of the two. He can turn his body into a dark gas. If you inhale it, he can re-form and kill you. He can float around as a dark cloud choking or bloodily exploding the life out of you. Apparently his clothes turn too (I don't recall him being naked after transformation).
When she is not being watched--with human sight--she turns into a super fast, super hard, multi-legged spider-like thing which is, uh, super strong--and COVERED WITH BLADES. When she transforms from human to nightmare-form she heals all damage. Her change is automatic: if she is unconscious and you take your eyes off her? Poof--she's fine.
Questions About The Characters
Here are some things we're not sure of. I've put my answers in here--but they can easily be corrected if the Worm author, Wildbow steps in.
- How susceptible is Fog to fire or other energy attacks? Will the fog "burn"? Would plasma bolts or radiation hurt him? My Answer: Somewhat--I would expect him to flee a really hot area--something hot enough to start breaking down other gases. I wouldn't expect "lasers" or something like the X-Men's Cyclops' blast to do much.
- How big does Fog's radius get. My Answer: Big enough to fill a livingroom.
- Can wind-blasts disrupt him--can he re-form if he is being actively dispersed? My Answer: Yes--but they don't harm him. If he was caught in something that truly scattered him (a nuclear explosion) I would expect him to die, even if in gas form.
- What can he do if you don't inhale him? My Answer: Not much.
- Can he kill several people at once--or must he pick one to reconstruct inside? My Answer: One at a time--it's him reforming and I wouldn't think he could do that in "several places."
- If her night-form was badly hurt and and she was then seen, would she appear unhurt--or bloody. Clearly going the other way regenerates her. My Answer: I ... don't know. I think it is more interesting if her night-form's damage remained. I think the rule would be she always wants to be in night-form rather than going back and forth constantly.
- Just how hard is she to hurt? My Answer: Pretty tough--but not indestructible. Enough to stand up to an assault rifle but not a heavy machine gun (this is a pure guess--she might be nearly invincible for all I know).
- Would Night transform if she was dead? My Answer: No. If you shot and killed her
Fog is straight-forward to a degree--although our examination of the rules found some holes that needed fixing. Night is much harder because of the absolute regeneration on transformation. We're still talking about that. If her night-form maintains damage it's much easier. If she insta-heals several times a fight ... much harder.
These are not characters you would want PCs to generally play--they make a very fearsome team for the right group but they are both incredibly one-sided when their approach works ... and very vulnerable when it does not. This is hardly idea for a PC Group. This doesn't mean their illegitimate -it just means playing them would have some ... challenges.
What is "Only when not being watched worth?" In JAGS terms it is probably either a LARGE (-30% cost) or VERY LARGE (-90% Cost). Right now those are the two big-league defect-levels and there's nothing in between (but you can have more than one LARGE).
Clearly for a ranged attack, VERY LARGE is too much: snipers always attack from parts unseen. But for hand-to-hand combatants it's a lot harder to get close without being seen. We are talking about the "totality of the circumstance" as a factor (i.e. she is teamed up with someone who makes it hard to see!)--but we don't really like that for most 'circumstances.'
At 90% Cost Break, a "D&D Thief Back-Stab" (which, presumably, has the same defect) would turn 10 APs into 100 APs. That's ... a lot. By any measure it is enough to end a single target of any reasonable point-scale. So we have to think carefully about that. Perhaps VERY LARGE should be more like 60% or 70% instead of 90%.
After some more consideration, I'll post the stats.
