Hello hello, may I request more info of the killermare siblings? Because they look so silly and wanna know more about them :33333
HAII!! I'm so happy that you like 'em!
MERCILLES
She is 19 years old, so she's the oldest out of the them. She has been an actress since she was seven years old, since Nightmare had the Power and money to do that, and she's really good in horror movies! She always dresses gothic, with the colors withe, black and purple. She's also lesbian.
When she was really little her life was okay, She didn't get traumatized (surprisengly) in any way...BUT (!!!) When she was 13-14 (because the phases of her Life have really specific ages hehe) she is a obsessed with dolls at a point where She only feels safe if She carries around one of them, because of the neglect she had from Nightmare. Even if Killer tries to be a good father and to be here for Mercilles, she still is more affected from Nightmare. She became really quiet and she was also developing a social anxiety because of how nervous she started getting. She was still famous for her roles in movies, so She was two different people at home (an insecure kid Who had mental breakdowns often) and on set (a pretty and okay teen star). The only people in her life (exept killer) that were there for her were her best friend Taylor and her girlfriend Viorel.
As she grown up a bit, she realized everything Nightmare did to her and started hating him. As soon as she turned 18, she bought her own house, with the Money she got with behing a celebrity, with her girlfriend Viorel!
So, She continued behing a (gothic) movie actress! She is trying to heal from her past, and Viorel is really helping her because she is really affectionate gf.\(>w<)ノ
MIDNIGHT
She is the Twin sister of Moonlight, both 16 years old.
She is emo (how she acts, dresses and music taste) and has anger issues. She always looked mad at everything and everyone, but not really as anger but mostly annoyed. As a child her and Moonlight were always together because she had no friends and Moonlight liked staying with her even if she acted bossy. She used to always dress boyish and steal Moonlight's clothes because She hated girly things. She used to always be mad and negative, wich sometimes amused Nightmare but It could also get on his nerves when she would yell (wich was often). She would also feel putted apart from getting most of the attention from people because Moonlight was the favorite and stuff, so she would often hit him out of rage.
She is really reserved and doesn't really like people, she doesn't really like school either (because in my au school EXISTS), she's really and introvert that would Just stay in her room all day reading fanfictions (she for sure is mentally ill)
She does not know her sexuality, maybe she's straight, maybe she's aroace, Who knows? She doesn't really care.
MOONLIGHT
He is the Twin of Midnight, but they are Polar opposites. He Always dressed feminine, even as a child, because in the multiverse there's no really the tought of 'female' and 'male' clothing, since they are skeletons...
He is gay and dates Charcoal sans (wich does not belong to me).
He has adhd, so he was very energetic as a child, and was really dumb (not because he had adhd, but because killer is his father). He would do anything Midnight told him, often getting in trouble. Him and his sister really needed attention 24/7 or else they would end up breaking something.
Since childood he had two best friends, Erica and Pastel. As they went to High school, they were kind of the 'mean girls' (the movie!!) but they pick on who does sonething to them in the First Place, sometimes...
He is the only positive one of the siblings because he didn't get traumatized as a child, he was kind of the favorite ig?? Because his sisters would get yelled at because they knowed what they were doing, but Moonlight didn't even think on his own- (´-﹏-`;)
And uhm.... That's all the lore i can think of right now, feel free to ask more questions, I would really appreciate it !! :3
How are killer and Nightmare when their kids are sick?
Nightmare would like give them medicine and soup and check twice in the day, meanwhile Killer would stay with them and cuddle if they want, but often ends up getting sick too.
Killer would check on his kids various times, because hes more worried than Nightmare is. I think he would also just give them company and play games. When the kids are little and can't stay alone sick all day, Nightmare doesn't give Killer any work to do, so he can take care of them.
I missed drawing them... ☹️
