I'm not really familiar with Monster High, so cool!

Name: Magma Flame

Monster parent: Devil (not trying to give any religion, it's just that that would be a cool charrie)
Gender: F

Powers: can summon and is invincible to fire (or related to fire, like lava and magma) and can fly

Best Friends: well, I'd like to wait until other people start before I say this.

Sense of Style: kind of goth and always wears black. 

Personality: everyone would think she's cold-hearted and merciless,  but she isn't. She was thrown out of you-know-where because of it. She's actually pretty nice, but she has a short temper.

Backround: as I said, she used to live in you-know-where but she was thrown out when they realized how nice she was. She wandered around for a while before she found this school.

Appearance: her skin is red and she has small wings. She has devil horns and a forked tail, and most people stray away from her because of that. (I know we're all monsters, but isn't a devil really high even on their standards?)

Top!

~My 2nd charrie~

Name: Marina BatYam

Monster Parent: Mermaid

Gender: Female

Powers: Breathes underwater, talks to fish and uther undersea creatures, has a singing voice that can control people, can swim REALLY fast, has a tail.

Best friends: Any sea monsters or sea creatures, her twin sister Malia, and any non-perfect mermaids.

Sense of style: Her tail is green, but she mostly wears a red tank top with a black biker's jacket. She died her hair jet black, and she puts it up in two buns with spikes.

Personality: Despite her appearance, Marina is actually really nice and helpful. She is outgoing, but she usually accidentally ruins everything, so monsters stay away from her. Unlike other mermaids, she is non-perfect. She doesn't do that well in school, even though she tries her best. She always mumbles because she doesn't want to accidentally hypnotize someone with her voice (She's part siren)

Backround: She ran away from home because she wasn't a 'perfect' mermaid and she was always messing stuff up. She became a 'rebel' mermaid, (If you ask anyone, the nicest rebel on the face of the earth) and she stopped worrying about being perfect. She still tried her best, though.

Name: Nikki Tepes 

Monster parent: Dracula

Gender: F

Powers: She has very limited control over people's emotions. She can suggest emotions by moving her eyes and fingers right but they are easy to resist by those who know what she is doing. The ones she can inflict on people best are fear, defeat, victory, worry, and sorrow.

Best Friends: Frost Monstra, Magma Flame.

Sense of style: She dresses in a pair of midnight black slacks and a short, stiff black cape that reaches just past her elbows and a white shirt. If she isn't wearing her cape, she wears a red shirt with an attached denim vest. 

Appearance: Midnight black hair with white streaks. Pale face, ovalar, manicured fingernails that are NOT sharp, curving fangs, slender and tall. 

Personality: Popular but doesn't value her friends very highly. She is a bit of a prime donna, a good deal of a drama queen. Even if she isn't angry, she lashes out. She is deadly sarcastic and a good deal of a bully. She is an extreme pesimest when it comes to how her potential and how good she is at things, even though she isn't at all bad. She works hard and is very determined.

Backround: She grew up in Dracula's dusty old castle and she hated it, so she ran off to the boarding school.

Hey! This looks really fun!

Name: Yamio

Age: 12

Monster parent: Vampire cat (sort of like a vampire BAT... whatever.)

Gender: Female

Powers: Is half cat, so does cat things (always lands on her feet, super climber/ acrobat, etc.). Doesn't drink blood, but still has fangs which she uses when she's in danger.

Best Friends: Her vampire cat, Rin (If you get the reference, please tell me: who's YOUR favorite vocaloid?).

Appearance: She has dirty blonde hair that's really curly and goes doen about half way between her shoulders and waist. Her everyday outfit: Frilly, white, just-above-knee-lengh dress, with tall black lace-up boots, and a red sash. Always wears a red leather coller with a little bell.

Personality: Quiet and a little creepy, but when she's with her vampire/cat, or close human friends (if she makes any), she's like a cat. (Playfull, bouncy)
She's not really friendly, because she learned not to trust anyone, and one can't always trust her...

Backround: Was rejected by her (adopted) vampire parents because she was part cat. She lived on the streets, getting trampled and stuff by everyone from gangs to the mayor.

P.S. If this thing shows up twice, that's because I went back and made some changes.

I deleted the first one for you, LS.

Name: Wolfie WereMoon

Monster parent: A werewolf by the name of Scarth Weremoon.

Gender: Female. (Everyone is female :P)

Powers: Can turn into a wolf at any time, turns into the giant actual-werewolf at full moon. She has sharp teeth too, and is NOT afraid to use it!

Best friends: Anyone with animal genes, like Yamio.

Sense of style: As she is a tomgirl, she usually wears ripped jeans of some sorts. She is slightly covered in fur, and pretty much wears a tanktop. Two wolf ears stick out of her very dark brown hair, and a kinda fluffish tail sticks out of the pants. She doesn't wear shoes. Green eyes.

Personality: LOVES animals, protective. Laughs a lot, good joker, and doesn't get offended easily. Loves to make friends, but dislikes girly girls.

Backstory: She used to live in her werewolf pack, but the werewolves all decided she should have an education, since she's pretty smart, and nearly as smart as the smartest-kid-in-the-school. They said to her after she was done she would come back. 

Name: Indigo Wave

Monster parent: The Kraken

Gender: Male

Powers: Can breath underwater and has elastic limbs.

Best Friends: Marina BatYam???

Sense of style: Likes to wear sunglasses and sandals, along with bahama shirts and capris. Wears snow goggles and a skin tight purple snow suit when it's cold.

Personality: Upbeat, intelligent.

Backround: The kraken sent him away from Greece for war reasons, and he landed in Marina's part of the ocean. Indigo is now on a lifelong mission to contact his father.
