Slenderman

Slenderman is a main character in Realities and the main antagonist in Slender: The Arrival.

Appearance
Slenderman looks just like how he looks in Slender: The Arrival.

Personality
Slenderman is normally very level-headed and calm, and is the main voice of reason among the eight characters. He is incredibly defensive of Kate, what with her being his proxy, and doesn't hesitate to step up to the plate when things need to be done. He enjoys killing people in many different ways, though, as he didn't seem at all concerned when he caused a man to die of fright when in the real world.

Powers/Abilities
Slenderman is able to teleport, something that not all the characters can do. He is able to extend his arms and legs quite long to make himself taller and appear more intimidating, and he can extend his tentacles, too. He is able to control fire and darken the area around him, and if he ever passes by an electrical machine/appliance, he causes it to malfunction until he gets a good distance from it. His tentacles can be used as weapons, a means of mobile movement, or as extra appendages, and the position that they're in underline what emotion he's currently feeling (for instance, if they were straight out, he would be surprised, and if they were sagging down, then he would be sad or tired).

Trivia

 * Since the creator, Creep E. Coyote, chose to have the characters' personalities be based off of how they behave in their respective games, it is unknown why he chose to have Slenderman act like he does; if Creep was following how Slenderman acts in-game, he would have made him cruel and uncaring, and even abusive to Kate.
