First, and this is more a pet peeve, why should physical abilities increase "exponentially"? Why don't these things ever increase linearly, quadratically, logarithmically, or just not in an manner easily representable by a basic mathematical function?
Since I don't care about making it exponential, changed to an unspecified increase.
I think the girl should be SCP-000, and the dolls should be SCP-000-1, rather than there being no SCP-000 at all.
Changed, for now; I suppose since the girl is the source, there's no reason she shouldn't be the SCP with no extra number.
There also isn't much of a hook. This is, as the thread title suggests, a Creepy Doll What Lets You Fight Good. But… so what?
Hmmmmm. Hard to tell when something will hook someone else, eh? Like your SCP-962 - it was interesting but not amazing until you added the rants, and then it became one of the highest-rated newbie articles on the site.
To me, the hook is the mental imagery of these doll soldiers. But then, my Photoshop isn't that amazing. Perhaps further description… hmmmm.
