These are the top ten scariest horror characters that I've seen so far, from least to greatest.
#10: Chucky, The killer doll from Child's play. He's more annoying then scary.
#9: Pinhead. I loved the Hellraiser movies, but Pinhead wasn't that scary.
#8: Jaws, the killer Great White shark.
#7: Ghostface. He was creepy, but not scary.
#5: The Shocker.
#4: Blade from The Puppet Master. He is more cool than scary, but I thought I should add him.
#3: The Thing.
#2: Michael Myers.
#1: Jack Attack, the killer jack-in-the box from Demonic Toys. I hate clowns!
