I’ve been thinking about the physical characteristics, or rather the possible ones, of a Slender Man. This is beyond height, width, color, etc. I mean physical capacities. Here are my current thoughts on said possibilities:
Biology: Nothing worthwhile can be said, other than it is clearly alive and humanoid in appearance, but is also clearly not a typical organism, as there is no clear face (and therefore entrance to the digestive tract or any external indication of sensory organs beyond touch). However, repeated reports suggest that it can see (“Sees me”). There is the possibility that the “face” does conceal a more typical arrangement, or some other portion of its body does. It may simply see in a different part of the spectrum, allowing it to see through its own skin. Alternatively, lens for its eyes may simply appear the same color as the surrounding material in the visible spectrum (compare that the external portion of the human eye has visibly transparent material, which is not transparent at all wavelengths).
Cross-Species Interface: It is possible that the creature can directly connect to the nervous system of a human being. This is evidenced by the blackouts attributed to its appearances. The most likely cause would be a thin, almost wire-like appendage (possibly either an extension of or modified tentacle) that can be easily inserted into the skin, possibly through bone, even, that can connect to and interfere with nerves electrically. This insertion, obviously, is either wiped from memory or entirely painless. This presumably has the potential of rewriting information, and even causing massive behavior changes. What changes are intended are impossible to be certain of, if any are explicitly desired. For all we know, this kind of interaction could be something akin to sex or drug usage, a pleasure-based or even necessary action.
Electronics Interface: I theorize that a similar or same appendage is used to interfere with electronics, sending impulses into them to disable, or even manipulate them. If this is sophisticated enough (as it would need to be to intelligently modify humans through the nervous system) a Slender Man could even implant information into the system, such as adding footage to a recording, either as it is being recorded or after the fact, depending on the storage medium.
These conclusions, if correct, are disturbing. Obviously I’d prefer them to be wrong, but if they are indeed correct, this might actually give an advantage. Knowing what to expect gives the opportunity to counteract.
Wearing thick clothing and a helmet (the motorcycle sort) could stave off the appendage, but it’s impossible to be completely shielded from something that passes through bone without ludicrous and costly accoutrements. Shielding electronics is easier, in that metal plating is comparatively cheap for smaller items, such as cameras, though the lens is still potentially an issue.
In the end, the most intriguing idea for me is trying to get non-visible imaging of the creature. My gut instinct is that ultraviolet is the best bet, but it could be anything. However, the imaging requires the chosen wavelength to have an external source. I can’t exactly lug around a gamma ray-emitting device for obvious reasons. Radio, on literally the other end of the spectrum, is unlikely to give me the resolution I would need for any meaningful analysis.
An ultraviolet source is much easier to obtain, or as they are commonly called, a black light. Unfortunately, the range wavelength-wise is smaller than I would like, but I actually own some currently, even if they are not on hand at the moment. This includes a small handheld one I can have on my person at all times. The only issue is a camera that can pick it up. However, I have a friend whose father likes to tinker in this sort of thing. I’ll see if he can get something jury rigged while I look for things online within my price range.
If this fails, infrared is the alternative imaging choice. It is even simpler, as normal cameras can pick up certain infrared wavelengths. However, if I were to use a normal camera, I would have to use a filter of some sort, else the infrared would be lost amid the visible light.
So there is my current plan. Secure and if necessary modify electronics to look at a monster that likely wishes to kill and/or mutilate humans, probably including myself, just so others can know about it. Oh, and it may be able to control both humans and electronics directly.
Sounds like an enjoyable pastime, doesn’t it?
