Slender Mann is a boss in Slender Fortress.
So far Slender Mann has displayed little observeable personality. Regardless, certain things might be determined regarding his unusual behaviour. Usually, he refrains from active participation in the daily events of the TF2 Freak World. Rather, he prefers to observe them from a safe distance, unseen. Whenever someone notices his presence his typical reaction is to simply vanish without a trace. Slender Mann is known to follow certain individuals on occasion. Sometimes he loses interest after a period of time and simply disappears. In other cases the individuals in question were found dismembered in desolate locations. As far as his personality is concerned, he seems to be a highly secretive entity. At present his goals and motivations are a complete unknown. Judging from his habit of observing others it may be speculated that he is quite curious. Moreover, he exhibited a creative, if somewhat malevolent, approach to the employment of his special abilities when directly attacked. However, it should be noted that he is normally passive. Whether or not he becomes aggressive when unprovoked cannot be definitively ascertained at this point in time. When he communicates telepathically he speaks with several voices. The voices are both male and female, eerie and reverberating. Even though they utter the same words they tend to do so out of sync, repeating certain parts or speaking ahead of each other.
In Slender FortressEdit
Slender Mann functions similar to that of the Slender Man. However, Slender Mann can appear at distant places within an impossibly short timespan, sometimes in closed spaces to boot. In addition to his signature stalking, he frequently uses it to avoid confrontations. Notably, he seems to employ the technique when being out of focus and tends to remain stationary when visible. However, this technique is also useful in combat, as Slender Mann may use it to confuse the player. The more violent the static gets, the closer the Slender Man is to killing the player. Simply being in his sight causes the static, and looking directly at him causes the static to get more brutal. Touching him instantly kills you. The Slender Mann has a gif that plays once he kills the player, which is from Freak Fortress 2.
