Imagine that Y/n is Joker's 19 year old daughter and is pregnant with Bane's child and Daddy J isn't too happy about the news. (Joker: Heath Ledger's, may he rest in peace.)

Warning: Mentioning of the word(s) throwing up,  period and cursing

(19 years ago) Joker and his wife, Harley were about to welcome their first child, a little girl, who he named Y/n.  When he held her for the first time, all he wanted to do was protect her from all things evil and Batman.  Harley didn't care much for y/n, because she didn't care for the name, first off. Whenever Joker had to go out, she would be there to babysit, but one night she just left, leaving the newborn all alone. When he got home, he heard y/n crying and went to aid his daughter. "Oh my poor little baby girl. Shh.... Daddy's here, sweetie. No more tears." He cooed softly as he soothed her. He notice that y/n wasn't fed or changed at all and that was the final straw. "We don't need mommy anyway, do we my little y/n?" He cooed as he changed her diaper. After she was changed, Joker put a bottle in the microwave for her to eat. Once the bottle was made, he took his baby girl over to the violet colored rocking chair, that looked all over Gotham and began to feed her. "I promise to raise you right without mommy. Daddy won't let anyone harm you and you are not allowed to date. You hear me, sweetheart. You only need me." He said as y/n giggled before snuggling up in her daddy's arms and falling asleep. "Goodnight, my sweet baby girl. Daddy loves you so much." He said as he gave her a kiss.

(Present day)- Y/n woke up one morning feeling very ill. You ran to the bathroom and began to throw up. Joker heard the commotion, he grabbed one of his knives and ran towards his beloved daughter. "Y/n? Are you okay in there, sweetie?" "I'm. (throws up)" He opened the door, set the knife back into his pocket and went to aid y/n. "You look very pale, honey. I think you should stay home today. Also you feel very warm." He said as he helped her to the bathroom sink so she could rinse her mouth and brush her teeth. "Let's get you to bed and I'll have one of my goons send you some medicine and some ginger ale." "Thanks dad." "No problem sweetheart. Now I'm going out for a little bit, but if you need anything, call me okay?" "Yes dad." "Alright my girl. I love you and I'll see you later." He said before he closed your bedroom door and left for his heist.  A little later there was a knock at your door and it was one of your dad's goons that had some antacids and a glass of ginger ale. "Thanks." "No problem y/n. " He said as closed the door. You went to see what the date was and you noticed that your period was two weeks late. "Oh no. Oh God please don't be what I think I might be." You said as you began to panic. You quickly grabbed your phone and called your best friend, b/f/n. (best friend's name) "Oh come b/f/n. Pick up the damn phone." "Hello?" "B/f/n?" "Y/n? What's wrong?" "Listen. Can you pick up a pregnancy test for me?" "Uh okay. Sure. But I may ask why?" "I'll explain everything when you come over, okay?" "Alright." (Time skip)

Your best friend knocked on the door and one of the goons answered it. "Hi. I'm b/f/n. I have some homework for y/n." "Just drop it and get out." The goon said. "Hey! That's my best friend you're talking to! Don't make me call my dad!" You yelled over the walkie-talkie. "Sorry about that. Please come in and y/n's room is just down the hall." "Thanks." "So did you get it?" "Yeah. Now explain to me on why you need this?" "My "aunt Flo" didn't visit me." "So? Go visit her." B/f/ said to make you laugh. "I think I'm late, b/f/n."  She looked at you and gave you a hug as to comfort you in your time of need. "Don't worry y/n. Let's just take the test and see what it says." She said to cheer you up.  "Okay. It says that we need to wait for two minutes."  Once the two minutes were up, you and y/b/f  looked at the test and saw a "plus" sign. "Oh no. My dad's gonna kill me and my boyfriend." You said as you quickly cleaned up. "Now y/n. For all we know it could a fake test. Why not just do the rest to see what the outcome is?" "Alright."  After you had taken all of the test all were positive.  "Damn it. What am I going to do b/f/n?  If my dad finds out I'm going to be in so much trouble." You said as sat on your bed.  "I think you should tell him, because lying will only make the situation worse.  If you don't mind me asking, but who's the father?" "Bane."  "Are you going to tell him that he's going to be a dad?" "I will, when the time is right." Just then your phone got text from your dad saying he was on his way home. "B/f/n. You need to go. My dad's coming home." You said as you girthed the garbage and hid it under your bed. B/f/n gave you a hug before leaving and heading back home.  

"Y/n? I'm home!" Your dad called out as he made his way to your bedroom. "Hey dad." "How are you feeling?" "Better. B/f/n stopped by to give me a paper for our school project that' due in two weeks. I hope you don't mind." "Not all baby girl.  B/f/n is your best friend. I won't get mad if you had her over and besides I like her." He said.  Later that night, your dad had a meeting to go to, so you used this time to call your boyfriend up and tell him the news.  "Hello?" "Hi Bane." "Y/n? Why weren't you at school today? I was worried sick." "I wasn't feeling too good this morning, so I stayed at home. But I have some news that I need to you." "What is it, my love?" "I'm pregnant." Bane was silent for a minute to take in what he just heard. "W-when did you find out?" "Today, when b/f/n came over. Are you mad?" "Why would you think that I would be mad at you? I love you and our unborn baby." He said as you began to cry. "Come on babe. Don't cry." "I'm crying because I'm just so happy. We're going to be family."  "I know. I can't wait to hold our little girl or boy in our arms." Your dad was walking towards your bedroom and listened to the conversation. "Does your dad know?" "No, but I'm going to tell him." "Tell me what, y/n?" "Dad! I-I thought you were out at a meeting." "Don't change the subject. What do you need to tell me and who are you on the phone with?" You knew better to lie to your dad so you began to tell him the truth.  "Y/n m/n (middle name) Napier!  How could you do this me, your father?!" "Dad. I'm sorry." "I forbid you to see that boy and talk to him! We will talk about this later. Right now I want to be alone." Your dad said as he heard you cry and closed your door. 

Joker POV: "My baby's pregnant. My Y/n is pregnant. I know that I should be happy for her, but I wanted to see her get married first to better man than that Bane guy. I hate Bane, because I know he's not good enough for my baby girl. Also I can't understand a damn word that comes out of his mouth! It's like you need captions to understand what the hell the guy is saying. I thought I was raising y/n right. All the memories of us playing her favorite, house. I was always the dad. Y/n would be the mom and one of her dolls would be our baby. I never thought she would go off and get pregnant at the age of 19. She's going to be a teen mom but I want her and the baby to have a better life for the both of them. I love them with all of my heart." (End of POV)

Joker walked back to y/n's room and went inside to see his daughter crying, still upset from before. "Y/n? Sweetheart. I'm sorry for how I acted. I shouldn't have yelled at you and took my anger and frustration out on you. I'm happy that I'm going to be a grandpa, but I just want the best for you and the baby. So do you forgive me?" You smiled and gave your dad a big hug. "Of course I do dad. I love you." "I love you too, y/n. Now since it's a Friday night how about we go watch y/f/TV/s (your favorite TV show) and I'll send out some goons for y/f/f (your favorite food(s)." He said to cheer you up. You nodded as your dad carried you.  

The next evening your dad had a lovely dinner set up, so he could meet and talk with the two of you.  You were taking a shower, while your dad placed a special gift on your bed. As you were making your way to your bedroom, you smiled at the gift your dad had gotten for you. It was a deep rich purple dress with sliver sparkles going around it and a nice pair of flats, since he wanted his little grandbaby to be safe as well as the mommy to be. You got dressed and went to show your dad how beautiful you looked. 

You made your way to the dinning room, where your dad was. He turned around and smiled at you. "Well hello beautiful. I see you got my gift." "Yes and I love it daddy. Thank you." "Only the best for my girl and my little grandchild." He said. Just the doorbell rang. You went to answer the door to Bane in a nice dress shirt and nice pair of dress pants. "Bane. Please come in." "Thank you y/n. How are you doing?" "I'm fine. I mean we're doing fine." You said with a smile and light laughter. "Oh good. Everyone's here." Your dad said as held you and Bane to the dining room.  Once all of you were seated, the chefs began to pass out the food then left to leave you and your family alone to eat in peace. After dinner, your dad asked Bane "So Bane. Are you going to marry my daughter, y/n?" "Yes, sir." "Do you plan to take care of my y/n and my grandchild?" "Yes, sir ."  "Good, but if you break my daughter's heart, make her cry, or eve cheat on her. I'm going to MURDER you." He said darkly as he held showed off his favorite knife.  "I promise I will not hurt y/n in any way. If I do then you can do whatever you wish to me." Bane said.  (Time skip to 7 months pregnant) 

Your dad had your best friend, b/f/n come to take you out for a while, so he, Bane and the other villains set up for your surprise baby shower.  Once all the decorating was done,  Catwoman went to go pick up the cake, while your dad and your boyfriend went to get changed for the party. 

Once Catwoman returned with cake, your dad told y/b/f that it was time to come back. As you and b/f/n closed the car doors, everyone waited for you to come in. Once you entered, everyone shouted "Happy Baby Shower, y/n!" You were in shock but you were very happy.  You had a lot of fun at baby shower. After everyone ate, it was time for the cake. (There will be two versions of the cake being cut.)

(Vision 1) As you and Bane cut into the cake, you saw the color... Blue. "Omg. We're having a baby boy. A little prince." You said as hugged Bane and your dad. 

(Vision 2) As you and Bane cut into the cake you saw the color... Pink. "Aw. We're having a baby girl. A little princess." You said as you hugged Bane and your dad.

After the cake you and Bane opened gifts and wrote down who brought what, so you and Bane could give out thank you cards to everyone.  Once everyone left, your dad had two more surprises for you, Bane and the baby.  "Since you two don't have a place of your own and this house is way too big for me. All of you can live here for as long as you want." "Oh daddy. Thank you." You said as you hugged him tight. "I'm not done yet princess. This last gift is for the baby." He cooed as he felt your bump.  He lead both of down the hall, where a white door was. "Close your eyes, y/n." He said as opened the door and guided you in. "Ta-da." "Omg. Daddy." You said as tears filled your eyes as you looked at your baby's nursery. 

"I added the crown, so the kid know that she/he is royalty." He said. "I love it dad. It's beautiful." You said taking in the nursery and caressing your baby bump. (Time skip to your due date and ER)

You were now the full nine months and water broke just a few hours ago. Your dad was right by side, since Bane fainted. "You're doing wonderful sweetie." Your dad cooed as he was encouraging you. At the last push, all of you heard the baby's cry. "Congratulations. It's a baby girl/boy." The doctor said as he handed you your newborn baby girl/boy. You were crying up a storm, but they were tears of joy. "Hello my sweet little baby girl/boy. Welcome to your new family." You cooed as your baby girl/boy gurgled and cooed. "Daddy's sleeping, so do you want to meet your grandpa? Dad, do you want to hold your granddaughter/grandson?" "I would be honored. Hey there little clown. I'm your grandpa. You're going to have so much fun with me." He cooed. As he held the newborn, it took him back to when you were born. "You're beautiful just like your mommy. What you got from your daddy I'll never know." He said to make the baby laugh. A little later a nurse came in to clean up the baby and to do the birth certificate. "What are you going to name the newest member of the family?" "Jackie/ Jackson  m/n (middle name) Napier." You said. "You're naming the baby after me?" "Yes. For you were there for me when mom left and you did a hell of a great job of raising me. The least I can do is name my child after my role model." You said, making your dad tear up.  "Okay, Ms. Napier. Here's your baby girl/boy." The nurse said as she gave you Jackie/Jackson. (If you don't like the names, you can fill it in with your names that you want.) You were getting sleepy, so your dad took Jackie/Jackson into his arms when she/he began to cry. "Don't cry little J. Grandpa here's. Shh... Grandpa's here little one." He cooed as he began to rock his granddaughter/grandson to sleep, while Bane was being aided in another room. "Welcome to the family, Jackie/Jackson."
