Slenderman was the first, just to let you know, so the Enderman is the alternate
Slenderman: So that's what i'd look like without my clothes
killed when looked upon
disappear & appear or something time to time
mostly found in a forest area or other areas
but then again they both CREEP ME THE FRICK OUT ; - ;
I say Slenderman is scarier because as I understand it you have to either approach or starre at an enderman to geth them to teleport behind you nd attack.
Slenderman can be anywhere....anywhere....
and hmmm I don't find either scary : O I'm not a slender fangirl, but I just find him cute XD same for enderman, I have a plushie of him on my bed lol
