I have some other ones to admit:
-Some of the ghost type Pokémon (Haunter, Gengar, Ghastly, etc.)
-A dark humor Internet picture where Winnie the Pooh was a zombie (it was probably something on Newgrounds or YTMND that I happened to stumble upon when I was little)
-Mr. Meaty on Nickelodeon
-The tiki-like creatures from the Lilo & Stitch video game, Trouble in Paradise
-Snakes (I still have that one to this day)
-Anything with a skull for a face (That's why I prefer Happy Tree Friends and other cute stuff when it comes to dark humor/horror because I like cute stuff and not scary looking stuff)
-Transformers (Optimus Prime is my avatar now. You can probably tell I got over this one pretty fast)
-The Incredible Hulk
-Shrek (I got over this one quickly as well)
-The children's book "Love That Dog" (It was a fear of losing my dog, not a fear of any ghosts or boogeymen)
-Scooby-Doo (the entire show)
-Mosquitos
-Moths
-Toys that move and make sounds
-Scary Halloween masks intended for horror/shock comedy
-Godzilla
-Bigfoot (I've never believed in him, I just thought he looked scary)
-Howler monkeys at the zoo
-The Nightmare Before Christmas
-Rick Astley (Just kidding, but I've always hated getting rickrolled)
I know how you feel, Rocky, I mean Rambo (sorry I didn't see the beloved bandana there for a second, jk!)
