SCP 6661
aka: the Demon Child
Object Class: Keter
Special Containment Procedures: SCP 6661 must be kept in a standard humanoid containment cell with multiple toys or books for entertainment. 6661 must be given daily food and exercise for a regular human being and no one apart from A-class personnel are allowed to converse with SCP 6661. Armed guards must be guarding the cell at all times.
In the event of a containment breach, all personnel on site must evacuate the area, and armed B-Class personnel will be sent out to recapture SCP 6661 and have permission to use rifles, bombs, and other extreme weapons.
Description:
SCP 6661 has the appearance of a human female with freckles, pinkish skin, blond shot ringlets in hair, and large blue eyes. 6661 normally wears a pink skirt with white socks and gloves and black shoes, as well as a purple-white bonnet and a bright pink bow in her hair.
Her demeaner is very friendly and cute, but also gullible and quite childish. This is only when SCP 6661 has taken the form of a child. 6661 has a cycle of aging which lasts 14 years. in those years, she will grow and shrink from a five year old child to a 19 year old young woman. However, she claims that her full name is Annabelle Sugar Epiphany Vil. When SCP 6661 is a teen or above, she will become more lustful and will often flirt with those who have a sexuality for the female gender. Annabelle may also make sexual advances on those she fancies. It is currently unknown how she figures out what the sexuality of someone is.
This ability may have something to do with SCP 6661's unnerving ability of manipulation. Though she pretends to be quite gullible, she is actually extremely manipulative and cunning, and knows a lot about human phycology and anatomy. Annabelle is so manipulative, that she once convinced a guard while out of containment that there wasn't really any blood on the walls of a room she was staying at. Annabelle is also an outstanding actor, and can even pretend to be a person's friend, companion, or romantic partner while secretly controlling them through her powers of manipulation. When asked what she really thought of these false friends she made, she replied, "none of them were really my friends at all. I didn't really give a f*** about any of them! They were just my toys to play with till- well, till the time came when I wanted to find a new one!" While being with them, Annabelle has tried to form fights between the person and the other friends they have, isolating them and making them hers, so no one else can have them. Annabelle has also been proven to be supremely sadistic, and takes enormous enjoyment out of the mental and physical pain of others.
Despite her normal appearance, Annabelle does have some supernatural properties apart from her eternal youth. Annabelle can stay active and healthy with horrific injuries, and has no response to the pain of these injuries. For example, a broken neck, or a twisted spine. Annabelle also doesn't mind causing these injuries to her own body, and in some cases, enjoys it. However, she can physically heal extremely fast: a broken neck can take only three hours to right itself. When Annabelle is very excited at causing and observing pain she's causing, her eye colour will turn red, and her pupils will become slits, and stretch to three time their original size. The most horrific thing that happens however, is with her mouth. Her teeth will elongate to up to five inches, and become extremely sharp and pointed. Meanwhile, her mouth will stretch over her whole face, a lot farther than a human mouth should be physically able to reach. As well as all this, the symbol of Satan will start glowing on the palm of her right hand, and the symbol of the Anti-Christ will glow on her the palm of her left hand.
Annabelle can also perform unnatural speed and strength, and has even been responsible for 6 mass murders, all of which have been of large mafia groups to whom Annabelle had claimed she had been spying for.
The major point about Annabelle, the Demon Child, is her so-called games. When she has decided she has mentally played with her victims enough, she will send them an invitation inviting them to a cupcake party at her home. When they arrive, she will give them a "special cupcake", which is filled with a very powerful sleeping drug which is normally put in tranquiliser darts, often used by hunters to catch animals like rhinos. When the victim is asleep, Annabelle will do one out of two things:
The first option is called, Event 6661-A. In this process, she will drag her victim into a cellar which appears under every home she moves into. There, she will immobilise her victim, chaining them to the wall, or strapping them onto a large metal table, normally used for taxidermy. Then, she will put on a dress made from the skin of many victims, as well as jewellery made from parts such as teeth, bones, or dried organs. She also will put on a tiara made from other human tissues. When her victim has woken up, if they are chained to the wall, she will proceed to physically abuse them using a range of knives, clubs, and other tools for torture. If she chooses to strap them to a table, she will cut open their bodies again and again, resealing the largest wounds with a substance which immediately gets rid of wounds, but also burns when touches the skin. If the victim is male, she will rape them as well. When she has decided that she's had enough fun, she will then cut open the victim's ribcage and ultimately dissect them alive. If she chooses, she may also make a part of their body into a new item of clothing. When the victim is dead, she will eat some of their body. When she has eaten her full, she will cut up the body and put the bits in cupcakes to sell to unsuspecting customers who don't realise they may be eating someone they've met.
The second option is known as Event 6661-B. In this event, the victim wakes up once they've entered her home, in a large house, strewn with the mangled corpses, blood, bones, and organs of her past victims. In this game, Annabelle's body starts deflecting all light, making her appear as a silhouette apart from her eyes, mouth, and the Satanic marks on her hands. She will tell the victim through a speaker that they must find clues to escape the house in a game of hide and seek. She will be wandering through the house, looking for the victim. Then, the victim must try and find a way to escape Annabelle's pocket dimension. When Annabelle sees them during this game, she will attack them using a blade with the capability to kill, such as a carving knife or a chainsaw. If the victim does not escape while she is chasing them, she will kill them. When they die, the mangled, horrific remains of a partially eaten body are left on the floor of her house, and Annabelle, and all traces of her, are gone. However, if the victim does manage to escape, they will appear in her house, still with the injuries they may have received from Annabelle during the game. She will then congratulate them on winning her game, and let them leave her home, promising that she wont touch them again for being such a good player.
