Basically my Oc is named Cassidy and she’s the younger sister of Casey Jones jr. they get sent back time and well… you should know the rest.

Chapter 1: Prologue

Chapter Text

This is how are story starts, the story before the actual story begins, weird right? But just bear with me. So first let me set the mood for you guys, the setting is on earth, of course, and in the future. But not the future with flying cars and whatnot, the future where an alien race dominated the planet, they called themselves; the Kraang.
Kraang are a very brutal and very evil race of aliens, and by this point in time we are at the moment, there are only a group of survivors left, probably only about 200 or so.
And if you already are from the fandom I’m writing for (which you probably are) you already know the rest, so I’m just gonna skip the rest of the explanation and jump right in.
So Leonardo, mutant ninja turtle, probably in his thirties, leading the resistance to stop the Kraang. He was talking with a couple of his colleges about their next attack on the evil wads of gum when he felt a tug on his pant leg. He didn’t even need to look down to see who it was, but he glanced down anyways to see his little protege, basically his son, Casey jr. the little boy looked upset, gripping onto him with a sour look on his face. Leo smiled and picked him up, continuing on with their planning. Once they were finished with their meeting Leo walked out of the room with Casey. “What’s wrong Case?” Leo asked, ruffling the little boy’s fluffy black hair. Casey looked up at him, his blue eyes filled with sadness.

“Can you play with me?”
He asked quietly and Leo sighed, looking a bit sad from Casey’s request, knowing he couldn’t at the moment.
“Sorry bud, I can’t right now. I have to do something really important.”
Casey nodded, looking down at the ground as Leo placed him down, ruffling his hair again.
“Don’t worry Casey. I’ll play with you later, okay?”
Casey nodded at Leo’s words and Leo smiled at him, feeling a bit bad he couldn’t play with him, but knowing Casey would feel happy once Leo played with him later.
Casey then watched Leo walk down the hallway and he walked the other direction, heading to Donnie’s lab, where the soft shell was taking to Draxum. Casey saw them talking and walked to a quieter part of the room, not wanting to interrupt.

Then he noticed something, he looked over to see a pod of sorts, only half covered by a piece of cloth, Casey pulled it off all the way and awed at it for a second, before running his fingers against the glass that was collecting dust.
Suddenly, a wirring noise gurgled from its insides and Casey jumped back when he saw it turn on.
He gasped and Draxum and Donnie turned to him, both going wide eyed when seeing him turning it on.
“Jones!”
Draxum exclaimed, making Casey jump as the goat yokai ran over, trying to turn it off, but it was too late.
The pod filled with a water like liquid and the control panel turned on, a timer starting on it before it started counting down the second first.
“What is it?”
Casey asked quietly, Draxum sighing and looking at him, his eyebrows knitted together in frustration.
“To put it in words you’ll understand, it is a creation pod. It makes any DNA you put in it and creates a new life form.”
Draxum explained and looked at Donnie, who looked at Casey.
The boy gasped and looked through the glass, seeing nothing, only the liquid.
“So it’ll make a baby?”
He asked and Donnie nodded.
“Yes, so in this case it had Cassandra’s DNA right?”
Draxum nodded at Donnie’s question and looked at Casey.
“which means. You might have a younger sibling.”
Casey gasped in delight and hugged the pod tightly.
“Really!? I’m gonna a have a baby sibling!?”
Donnie nodded and sighed, typing something into his computer quickly before pressing the send button and looking at Casey and Draxum.
“Looks like we have to prepare for another baby. Again.”

Nine months later, the baby came. April held her gently in her arms, a soft smile gracing her lips as she looked down at the baby girl in her arms, sleeping peacefully in her arms.
April walked into the room where everyone was waiting.
Mikey and Raph came up first, April handing the baby over to Raph. She seemed even tinier in Raph’s large arms, he could hold her in just his hand.
His large finger stroked her soft cheek and he smiled in delight, stars shining in his eyes and he kissed her cheek gently.
“You are so cute.”
He muttered as Donnie and Leo came over, Leo holding Casey’s hand as they came to see the new addition to the family.
“I wanna hold her too.”
Leo informed, making Raph chuckle and hand the baby girl to Leo, the red eared slider melting at her cuteness and innocence.
“Aw, I remember when Casey was like this.”
Leo commented quietly, moving a strand of black hair out of the baby’s face.
Donnie looked over his shoulder and smiled warmly, not saying anything as Mikey took the baby in his arms.
Mikey smiled down at her and he kneeled, so Casey could see his new baby’ sister.
“Wanna hold her?”
Mikey asked and Casey nodded quickly, a smile appearing on his face as Mikey handed the baby over to him gently, arranging his arms so he could hold her properly.
“Remember to hold her head.”
Mikey informed and soon Casey was holding her properly, looking down at her in awe.
“She’s my sister?”
He asked and Mikey nodded with a chuckle, and Casey looked back down at the baby, before smiling brightly.

“I love her.”
