🖤Batman Villains One-shots🖤 [REQUEST OPEN]

Peinguin x Sister reader

Note : (Y/N) is a woman

/ The night was calm today. The stars shone brightly and only the gunshots and howls served as a nocturnal orchestra. The room you were in was also quiet. Only works of art, stuffed animals and luxurious furniture kept you company. Your big brother was still doing his business. Your older brother and your family in general were well known enough, but not in a positive way. Indeed, you were the little sister of the famous Oswald Chesterfield Cobblepot.
No one knew except the people working with Oswald that you were related to him. Unlike the rest of your family, you were neither crazy nor a criminal or presented no trauma or psychological risk. You were a beautiful young girl with long black hair with blue eyes like your brother, with a normal height, who was passionate about piano, drawing and singing.
Despite what we could think, Oswald loved you very much. With his birds, you were his only light in his childhood. You were beautiful, radiant and adorable as a dove. You had never judged him for his poor physique and you saw him as your hero. Like any little sister. Oswald saw you as his favorite little bird. Of course he never dared show his affection for you in front of everyone. He was the King of Gotham after all. But that didn't stop him from protecting you, from giving you everything you wanted, from keeping you company.
Suddenly, you heard some screams of pain and fightings. Then you heard your beloved brother's voice. Some men must had failed a mission or something like that. After a few yell and a shot, Oswald arrived in the room. He was angry you could tell. This is why you didn't say anything at first. But your brother noticed you anyway\

Oswald : It's nothing sissy. Just bad day. Like others.

(Y/N) : I don't doubt it brother. What did they do this time ?

/Oswald clucked a little but tried to remain calm and normal. But you knew your brother too well. You know something was wrong\

(Y/N) : Brother I'm old enough to know things. I've seen and heard horrible things. You don't have to hide everything from me.

Oswald : It's nothing really ! You don't have to be worried about anything. I have anything under control.

(Y/N) : How can I be worried if you don't tell me anything ?

Oswald : You sassy. Right .. well .. those bloody idiots .. because of them Batman knows about you. He heard them talking about you.

/ A long and heavy sigh came out of your mouth. You knew that one day you will no longer be a secret anymore. It was obvious. But hey, even if this day had come, it wasn't the end of the world for you. On the contrary, you didn't care. As long as your big brother was safe.
Oswald saw at your face that you didn't seem to be worried. At first he was relieved to see his dear lil bird not scared but now he seemed to be more confused. Didn't you hear right ? Did you know how serious it was ?\

Oswald : You're ... okay sissy ?

(Y/N) : Hm ? Oh yeah I'm fine ! It's nothing really.

Oswald : N Nothing !? What do you bloody mean by nothing ?! The Bats knows who you are and your existance !!

(Y/N) : So ?

Oswald : So he can kidnap you, use you against me, hurt you !! Take you away from me ... Do you realise how much-

(Y/N) : And are you going to let that happen ?

Oswald : W What ?! Of course no !!!

(Y/N) : Then we're fine. I'm fine.

/ A silence settled in the room for a moment. The King of Gotham decided to sit in his favourite chair and try to relax. It is true that he could be very dramatic and worried about his collection and money. But his sister was a different subject. She was his only one. There was no other like her in the world. He couldn't replace her. She was unique and pure. If Batman or someone else dared to touch her ... Oswald would go really mad.
As he always said, he always gets what he wants. But for his sister, he could do anything. Even destroy his most precious collection. If she asks she gets. If she wants to have the whole city at her feets, Oswald would do everything to make her wish real.
You looked at your brother and got up from your seat. You put your arms around your brother's neck and hugged him gently. You kissed the top of his head \

(Y/N) : I'm going to be fine brother. I promise. You always protected me, no matter what.

Oswald : I know I know.

(Y/N) : This Batman sure brang you a lot of problems ..

Oswald : Ha ! Damn yes he does ! I hate him .. more now.

(Y/N) : I don't really like him too ... he caused you so much troubles ...

Oswald : Don't worry sissy. I'm stronger than him.

/ You started to look at the window. You didn't even notice that it started to rain. After a few minutes, a bright idea popped in your head\

(Y/N) : Brother .. ? You know that my brithday is in one month ?

Oswald : Of course I know that ! Why are you asking me this ? Got an idea for your gift ?

(Y/N) : Actually yes. I want Batman dead.

Oswald : W What .. ?

(Y/N) : You want me to be the happiest woman on the planet right ?

Oswald : Yes of course !!

(Y/N) : Then I want Batman dead. If he's dead, I would be really happy because I would feel safer and you will no longer have problems because of him.

/ A silence settled in the room. Oswald looked at his sister. He always wanted to kill the Bat but it was never his top priority. But now his sister wanted his death as a gift. He couldn't fail her. He promised. He promised to his momma to always make her happy. He promised !! \

Oswald : You will have your gift sissy. I promise.

(Y/N) : I don't doubt it. After all you are the best big brother in the world ! [And I don't want that bat to ruin it]
