Vs. Scorpion: Jeez '12 Noob, learn to spell. Anyway, the battle greatly nerf Scorpion's hellfire manipulation, restricting it to only a few attacks. Slenderman can't cause his target to see only static. The static that you see in the Slenderman games is his presence messing with the player character's camera.
Vs. Freddy Krueger:
Where are Slendy's tentacles, Beast? WHERE ARE HIS TENTACLES?! EDIT: Again, he does not have the ability to make his targets see static, that's just him messing with the camera.
EDIT: Removed the Harry Potter challange.
