I went away from the forums for a while, and not only forgot my old password, but I no longer have the email address I linked it too. But some things are interesting enough to make me give up on trying to remember what obscure reference I used and just make a new profile.
I've been reading the Shapeshifting threads (kudos to TheRealLemming (is there a false one out there?) and the rest on discussions that are insightful, interesting, and civil at the same time) and had a thought, a different way of looking at the sensory affecting powers that I'd like to share, on the offhand chance that others may find them interesting or enlightening and want to help me explore the idea further.
When you perceive someone in the Hero system, you notice three things:
Their presence, which includes things like their more-or-less exact location. Darkness and Invisibility prevent one from accurately noting someone’s presence.
Their general signature, which allows you to figure out that they’re say, human or a dinosaur or a cat. Shapeshift can change someone’s general signature, and images can create things with general signatures.
Their specific signature, which allows to to figure out that they’re Dr. Strange or Godzilla or Cuddles the SuperKitten. Shapeshift with the Imitation adder allows you to change your specific signature, and Images could probably create images with specific signatures, though I suspect that would give a bonus to the PER roll to see through them.
Note that if you can’t detect someone’s presence, you can’t see their general or specific signature. And I’m unable to imagine a situation where you can identify someone’s specific signature, but not their general signature--and I consider myself to be fairly imaginative. I consider the signatures thus tiered: Presence (General Signature (Specific Signature)
Thus I propose the following two powers (or something like them):
Concealment prevents people from detecting presences. It normally costs END, is ranged, fills one hex (+1 enhancement to increase the radius by 1â€) and costs 5 points per level. Each level covers a Sensory Group, and targeting Sensory Groups take 2 levels. In other words, it works just like Darkness in the book.
Normally, Concealment has a “fringeâ€--anyone within one hex of the effect can make a PER roll to see through it. Eliminating this effect takes 1 level, and is effectively identical to buying the “touch†sense group.
(I actually like a slightly modified version of the sense groups that makes the whole “fringe†thing more intuitive ... ask if you care)
By applying the limitation Self Only (-1/2) and IPE (+2 for both the source of the power and the use of the power itself) we get invisibility: you can’t note my presence, and you don’t realize that you can’t. This is identical to the book cost for invisibility: 5*(3/1.5)=10 for nontargetting senses, and 20 for senses that are typically targeting.
The second power is Signature Control. It normally costs END, is ranged, fills one hex (+1/4 enhancement to increase the radius by 1â€), has IPE, and costs some number points per level. Each level allows you to create (or, if chosen when bought, remove) general signatures from a single sense group, and typically Discriminatory sense groups cost double (or, if you prefer, Targeting groups, but that seems a little silly to me). Signature Alteration may take the Set Affect limitation, having only a small range of effect (any humanoid signature) for a -1/2 limitation, or only a single signature for a -1 limitation.
It has the “fringe†effect like Concealment, above.
Being able to control specific signatures is an adder, which should be priced appropriately to mimic the affects of imitation for shapeshift.
To make it match Images, apply the Limitation: Side Effect--observers see through the signature created if they succeed in a modified PER roll. Would that be a -1 or -1/2 limitation? I expect all of you have a better feel for this than I, but it looks like a RSR-type situation to me. The limitation would also make the normal roll to detect a “fringe†automatically go in favor of the observer.
To make something like Shapeshift, do not apply the side effect limitation, and instead apply the Self Only limitation. Buy appropriate levels to cover Vision, Touch, and Sound and whatever else you care about.
I’m not sure whether you should have to purchase it twice (once to eliminate your own signature, once to create another signature for people to see) or if “covers over already present signatures†should be an enhancement or free or what. I’m going to play more with numbers, and I welcome suggestions.
Now it becomes very clear whether to purchase “shapeshift†for your character: if you can actually make yourself unrecognizable, then you do. If you just “look different†but still have enough of your own features to be easily identifiable, don’t. It's just the SFX of whatever other powers you have. I don’t think Plastic Man had Signature Control, except possibly to the Touch (or “fringeâ€) group...I can imagine some scene where a blind passerby mistakes him for an actual piece of scenery. It would be amusing enough to be appropriate to the show. He does, however, have some limited desolid or "shrinking" or something for slithering under doors and hiding in people's pouches and the like.
Similarly, “Cool Blue Plastic Ball†would be Personal Signature Control for the Visual group and the Chemical group, and the Touch group. You haven’t changed your voice, your mind, and whether people with discriminatory radio senses can actually identify you (and whether they could before) is between you, your god, and your GM.
You obviously can’t use Signature Control to slip out of ropes or through small gaps...use limited desolid, or some sort or limited constant teleportation or something if you want those effects. And if you want to turn into a trampoline or a ladder or a hang glider, go buy some other powers for that effect, or try to con your GM into saying it’s a Power Stunt appropriate to your SFX.
It’s now also intuitive to purchase things like Anonymity--You can tell I’m here, but you can’t figure out who I am. Things like voice scramblers, or, with IPE, the “Hi, you don’t know me, I’m Mr. Nobody" power seen in many other games and oh-so-useful for dodging the guards who have your description, or the reporters who have been hounding you, without actually giving you the ability to look like a whole other person.
On a complete side note:
I’d love make “background†an effective sense group, so that Concealment can be bought for it (to make someone untraceable) and Signature Control to give you fleshed out secret identities you can use, effectively replacing the Deep Cover perk. Leet Hacker Girl could use this power on others for as long as she's still sitting in front of her computer plugging holes in records, while SuperSpyMan could have a range of covers, allowing his background to make him appear to be, say, a wealthy industrialist from any country he chooses. Kaiser Sose could use it to pose as anyone (though someone who knows his face sees right through it), and the Master of Disguise can pull out the paperwork to show he is who he claims to be, whoever that happens to be today...
