So I'm gonna put my human OCs and my Monster OC. My monster OC has a love interest, one of my human OCs is a child and so has no love interest, my other human OC has the same love interest as my monster one.

Monster OC

Name: Shady

Species: Bunny girl style monster

Age: 28

Looks: She is a humanoid with grey skin, and long messy black hair, as well as grey bunny ears as well as a bunny nose. She wears black flared jeans, a dark purple leather corset top, purple platform boots, grey fingerless gloves, spiked wristbands, a spiked belt, a black choker, and a necklace. She also has piercings in each ear. She has dark blue eyes.

Abilities/powers: Sensitive hearing

Role: Side character (in game)

Personality: She may be outgoing and sometimes sarcastic as all heck, but she's actually a huge softie. Show her something cute and she'll melt. She also is a caring monster, having grown up raising her to younger siblings without an adult there to raise them. She, in turn, feels like she has to always be responsible. She likes to party though! And loves to have fun. 

Backstory:

Shady had to grow up young. Her mother passed when Shady was only 17, leaving her alone to raise her younger siblings (who were 13 and 12). Because of that she would do whatever she could to raise the gold to afford to look after them. She ended up sneaking into the ruins, picking the lock if she had to, and exploring. Eventually finding the area just below the hole on the surface, and finding a few human items scattered around that had been dropped down there by passers-by. She gathered the items and started selling them for gold.

Soon she opened her own shop, going to the ruins, now with permission, to scavenge more items to sell, just to raise money to care for her siblings. 

During one of her trips to gather items, she found an MP3 player, and decided to listen to it and soon found a love for human music, especially rock music. She began singing some of these songs in public spaces to earn even more cash.

Love interest: Mettaton (This is an AU where he just stays in his EX form)

Occupation: She runs a shop where she sells things humans have accidentally dropped down the hole on the mountain over the years. Not items from fallen humans, but just general stuff people dropped while passing the hole. She found an old MP3 that was dropped down the hole and kept it, listening to the music and then singing the stuff she heard in public for extra cash.

Human OC 1 (Child)

Name: Lily Bronwyn

Age: 10

Looks: A short kid with frizzy brown hair and green eyes. She has a lot of freckles. She wears a pinafore dress but made of denim, along with white tights, black shoes and a pink t-shirt. Her hair is in short pigtails.

Weapon: None

Armour: None

Pacifist, genocide or neutral: Pacifist

Soul: Light green, meaning Curiosity

Personality: A shy and quiet girl, she is incredibly curious. She likes to explore new places, and learn new things. In fact her fall to the underground was not accidental, she jumped down the hole, using an old blanket as a makeshift parachute, purely because she was curious about this world of monsters. She is very non-confrontational, and isn't one to speak up unless comfortable with people. She is friendly though, but also easily frightened despite putting herself in dangerous positions to satisfy her curiosity.

Backstory:

Lily was an orphan. She never knew her parents, and the orphanage she lived in didn't really pay much mind to what the kids did, so Lily would often go out and explore her home town, visit the library or just go anywhere. She just wanted to learn or see new things. 

One day she heard of the underground and the war between humans and monsters. Curious to see this world of monsters, she hiked up Mt Ebott, taking her blanket with her, and jumped down the hole using the blanket as a makeshift parachute. She managed to stay under the radar for a while, avoiding monsters, but every time she encountered one she would hide.

Eventually she ended up living with Toriel, happy to stay there as she finally had a family of sorts. However, when Frisk fell into the underground and went to leave, Lily's curiosity about the rest of the monsters got the better of her and she followed the other human.

She still views Toriel as a mother, and depending on what route is taken, Lily's fate changes. In a pacifist route, she and everyone else go to the surface, and she ends up being raised by Toriel and Asgore (As I like to imagine they got back together after going to the surface), in a neutral run she returns to being in Toriels care instead of leaving the underground with Frisk. 

Friend: N/A (depends on RP)

Human OC 2 (Adult OC)

Name: Rosaline "Rose" McGarden

Age: 27

Looks: Long blonde hair and green eyes. She often dresses in vintage style clothing, attire seemingly inspired by 50s fashion. She also has a few added items she uses to disguise herself as a monster so she can wander the underground without people trying to pick fights with her. These items include fake fangs, fake cat ears, and contacts to make her eyes appear less human, as well as a mask to hide her face so she doesn't look human at all.

Weapon: A Parasoul

Armour: Paint stained gloves

Pacifist, genocide or neutral: Pacifist

Soul: Lilac, Creativity

Personality: She is a calm woman who enjoys all forms of creative hobbies. She is cheery and very sociable, finding it easy to strike up conversations with others. She does hold a grudge though, so be careful. She may give the cold shoulder when upset. She is well mannered, and loves a good laugh.

Backstory:

Rose was heading up the mountain, intending to find a spot to paint in peace. She wasn't paying attention to what was in front, instead admiring the sky as she thought it would make a beautiful painting, and in turn she fell from not looking where she was going.

Knowing of the hostility between humans and monsters, she quickly made a plan, using the art supplies she'd been carrying, she made some fake ears and mask so she could disguise herself as a monster. The only monsters who know the truth of her being human are Toriel and Sans.

She started doing paintings and art projects in the underground and became a decently well known artist down there, so much so that eventually she was invited as a guest on Mettaton's show. It was while she was there, thankfully back stage, that her mask fell off revealing her to be human, though the only witness was MTT himself. Though by this point, she'd spoken to him a few times and he considered her a friend so he agreed to keep her secret.

Love interest: Mettaton

Occupation: Artist
