A Quick Inventory

Assumption 1: The Phenomena is a product of the Tulpa Effect
Assumption 2: The Phenomena was sparked by the 'initial' post on SomethingAwful.

Syllogism 1: Everything that has ever happened in regards to the Phenomena is linked to that initial post in SomethingAwful
Syllogism 2: The Phenomena can only have existed since that initial post.
Syllogism 3: While the Phenomena was sparked in our heads, it has spiraled out of control.

Tulpa Effect: To shortly paraphrase, by the process of belief, something becomes real.

Physical Description:
Tall, lanky in build.  Arms/legs/fingers may appear unusual in length.  Always wearing a professional business suit.

Known Abilities:

Some special form of transportation not completely unlike 'teleportation'.
-Can appear/disappear from closed rooms.
-Can shake off any pursuer.
-Can transport between places that do not make logical sense (e.g. entering one room and exiting from one across the house in a matter of moments).
---Any of the above can be used to transport others, as well.

Radar that allows Him to track those 'infected' by him.
-Can follow anyone infected by him without fail.
---Can be deterred and prolonged

Ability to change bodily structure.
-Can form extra appendages (tentacles).
-Can stretch His arms and appendages
---Can be stretched in a manner that hypnotizes people into dropping defenses / makes them unable to run.

Influencing the minds of humans.
-Able to erase large spans of short-term memory (this allows people to act as they normally do, but removes the ability to recall their actions at a later point).
-Able to influence minds into submission and create those who will follow his instructions (from hereon out referred to as 'Hollowing them out')

Odd aura.
-Brings out a reoccurring cough in those who he has begun to Hollow.
-Causes electronics to behave strangely / stop working.

"Invisibility".
-Cannot be seen except by those infected or children (?)
---Can be captured on film

Deification.
-Will be explained in later posts, but essentially having become a god-like entity in our eyes.
---Yes, this means a lot of bad shit.  Therefore, it'll probably get it's own post.


Roads to becoming Infected:
-Delving into the Slenderman Mythos (by choice or by fate, the end justifies the means)
-Contact with an Infected individual, followed by investigation into their circumstances.
-Pure chance

How to tell if someone is Infected:
-Habitual drawing of the Operator Symbol
-Reoccurring cough
-Spouting out odd foreboding bullshit
-Paranoia
-Films goddamn everything

Methods of fighting Infection:
-Fucking memory wipes (really?  Ugh I'll talk about this later).
-Spamming the Operator Symbol (This is also getting it's own post because this is kind of a big deal).
-Running (For more on this, read the Tutorial.  M knows his shit).
-Focus on something else (I think everyone ALWAYS forgets this one, so I'm definitely doing a post on this later).
