Nightmare Fetishist

Anime & Manga

 * The Wallflower: Female lead Sunako Nakahara is a lover of solitude, gore movies, banned gore movies, anatomical dolls, and objects that reflect "the ugly side of life", as she puts it. And she tends to be pretty creepy herself.
 * Ouran High School Host Club has Nekozawa and his friends from the Black Magic Club, who are obsessed with curses and all kinds of creepy things. They're quite a happy bunch, too. Most of the characters regard them as harmless geeks, not so much scared as bored with their ideas. Tamaki, however, is scared beyond belief of Nekozawa and his "powers", so from his perspective at least this trop is played straight.
 * Kujyou Himeka of Kamichama Karin think bugs are cute. All types of bugs. This includes cockroaches and termites.
 * Shinra of Durarara!! makes it known that he thinks Celty is beautiful without a head. He also spent most of grade school and high school fanboying Shizuo's crazy rage fits.
 * Black Butler:
 * Maylene goes into fangirl mode upon seeing a mummy in episode 4.
 * Grell gets really excited at the thought of both cutting Sebastian into pieces and having his babies.
 * Undertaker enjoys the feeling of having the water sucked out of his body while being buried neck-deep in salt.

Films - Animation

 * The Nightmare Before Christmas: Everyone in Halloween Town. There's a moment when Jack roars at Lock, Shock, and Barrel to scare them into shutting up. Shock almost looks like she's going to faint... and not with fear.

Western Animation

 * As mentioned in Film, Lydia in the 'toon version of Beetlejuice not only became best friends with the gentler (but still revolting) Beej, she's been show to own spiders and worms; and everything she does from starting a band ("The Brides of Funkenstein") to designing Shakespearean costumes (which got Ol' Will's thumbs up of approval) has strong Gothic undertones. She also spends a lot of time in the Neitherworld, where she has several other ghostly pals in addition to the B-guy.
 * In Growing Up Creepie, Creepie Chreecher falls in love with a boy working at a carnival who she believes is half-tarantula, but loses interest when she finds out it was just a costume. In a later episode, her interest in him returns once she finds out his adoptive mother is a giant spider.
 * Ed of Ed, Edd n Eddy is a little too obsessed with horror movies and comic books. One episode has him smile merrily when it seems he have summoned in an Ultimate Evil. A few episodes have even had him grinning as the Kankers close to him and the other Eds.
 * Carl from As Told by Ginger is an unusual boy who loves bizarre things. His prized possession is a petrified eyeball.
 * Lucy Loud from The Loud House is obsessed with all things dark and macabre. She even claims to be in love with a fictional Nosferatu-esque vampire.
 * Luz of The Owl House has more than a passing interest in everything macabre and mythological. She's absolutely thrilled when she arrives in The Boiling Isles.
