Hi there! I know this crossover might seem strange, but I hope you all enjoy it!

This plot idea randomly came to me as I was listening to the Mattimeo audiobook.

Anyway, if you are new to my TMNT fics, I have two TMNT OCs, Asami and Lupa Hamato. A brief summation of their story is this; when Asami was 5, Mushimi, Yoshi's friend, kills Tang Shen, Asami's mom. Shortly afterward, Asami and her dad, Yoshi, move to NYC, but then not long after they settled in, Yoshi is killed, leaving poor Asami an orphan. Asami is taken in by Mr. Mortu, Yoshi's boss and an Utrom. Mr. Mortu decides to show her the human parts of TCRI, but Asami sees a room of puppies TCRI are caring for and wanders into the room. Then an alarm to warn of transmit testing goes off and Asami assumes it means she's in trouble, so she takes off, running out of TCRI before anyone realizes she's gone, not realizing she still held a wolf puppy.

She ends up in the sewers and the van that had the canister of ooze is looking for her, and thus the accident that mutated the turtles and Splinter also mutates Asami and the puppy into anthropomorphic wolves. Asami can't remember much from before the mutation, however, due to the stress the mutation put on her body, so she can't remember her own name. So Splinter, thinking the Foot killed Asami after killing Yoshi, ends up naming Asami after herself.

It wouldn't be until the end of season 1 that Asami meets Mr. Mortu and learns who she is and about her life before the mutation. But since this story takes place before the end of season 1, she won't learn for sure that she has always been Asami. But she accepts that regardless of who she was, she is now Hamato Asami, and that's that.

Hope that all made sense!

God Bless and Good Day!

Hamato Splinter has been having strange dreams lately.

They show his beloved Master Yoshi performing some strange ritual, drawing strange symbols on a wall in chalk, pouring water below his drawing, and beginning a chant that would seem to echo around the room when Splinter woke.

He would try to mimic the chant, to little effect, but soon he had to exit his room and begin a new day of caring for the children he had decided to take in after that glowing ooze changed them all.

He had settled into his role as caretaker of the six beings with surprisingly few major hiccups.

The older girl proved instrumental in settling the odd little group in what appeared to be an abandoned tunnel, isolated from any sewer workers that might stumble on them.

The poor girl doesn't talk much, except to give Splinter advice or to instruct, scold, or otherwise interact with her siblings.

Siblings…

Splinter doesn't remember if he ever had siblings, but he enjoys watching the children interact, even if he has to intervene sometimes. In some strange way, he thinks, they make a family, like the one he had…before.

Before that fateful night in Japan, when a jealous man cut down an innocent woman and left her child motherless.

Splinter can't remember much of his previous life, but what he does remember makes him ache with longing for the life he had, the happiness before the tides of change.

He shakes himself. Now is not the time for wallowing in the past. He must focus if he wishes to acquire more food for him and his little family.

To that end, he takes a breath to steady himself and adjusts his position under a manhole cover to reach up and slide the heavy metal disk aside as quietly as he could.

He wishes there was a better way to feed his family, even after nearly 12 years of living this way, to care for the children the way they deserve, but with their unique appearance, he knows they must remain hidden and safe in the shadows.

So he searches the dumpsters behind a grocery store quickly, smelling various foods and grabbing what looked and smelled edible then moving on.

Luckily, he had learned the art of Ninjutsu by watching his Master Yoshi from his cage, thus remaining undetected by any pedestrians as he fills the bag with what food he could find.

Splinter sighs as he finally retreats to the safety of the sewers, heading home on a frequented route.

These excursions granted him peace and quiet so he could consider what to do. He had decided a long time ago that he would pass his skills to his children, just in case someone discovered them and to honor Master Yoshi's memory, but precisely what would come of this training remained unclear.

The eldest, who he named after Master Yoshi's lost daughter, had picked it up the fastest, as she was around the age Yoshi had been when he started his training with the Ancient One.

Ah, the Ancient One…so mysterious, so wise. Master Splinter had enjoyed meeting the old man in his new form, though the circumstances were less than ideal for a reunion.

The Ancient One nearly buckled under the weight of Splinter's news, but had borne it as best he could.

"That girl, Splinter-san…who is she?" The Ancient One had asked. Splinter had to tell him the unfortunate girl could not remember her name and much of her old life after the trauma and stress of the mutation, so he had named her after the child of his Master Yoshi, to honor her. The Ancient One had mused that Asami was around the same age as her namesake, but neither him nor Splinter thought much more of it, deciding that fate had brought the girl to Splinter for an unknown reason.

The mystery of Asami's true identity was one that plagued Splinter and Asami after they left the Ancient One, but they persevered as best they could.

As he nears the little home they had made, he takes a deep breath to collect himself and enters the room.

"Daddy!"

"Welcome back, Dad."

"Guys, Dad's home with food!"

He's greeted with hugs or smiles as he makes his way to the kitchen. "Thank you, children." He replies, setting the bag down on the table as the kids take their seats.

"Everything went fine while you were gone." Asami reports, as usual, bringing over their plates and cutlery.

She had a certain way of handling her siblings so they didn't get into too much mischief in Splinter's absence.

"Thank you, Musume." He replies gratefully. He doesn't know how he would have handled raising the children without her, and made sure to show gratitude when he could.

The rest of the evening passed in the usual way; after dinner, Asami gathered the plates and washed them with a sink the pair had found in a landfill.

Then, Splinter and Asami would read a few chapters of books they'd taken from small free libraries around the city.

Then the kids were allowed to watch a little bit of TV while Splinter read a book. That was how he had come to understand much of the world, its customs, and the English language.

A strange feeling slowly came to Splinter, and he found the book unentertaining. He checked the time and realized it was bedtime.

Calling the children, they began their bedtime routine with a few murmurs of discontent.

The feeling grew stronger as Splinter tucked the children in, wishing them all a good night's rest before he was left alone in the main area of their home, facing an empty wall that suddenly seemed interesting.

Acting on a strange impulse, he grabbed chalk the children were fond of drawing with and a glass of water.

As if asleep, Splinter moved the chalk on the wall, imitating the symbols he had seen in his dreams as best he could.

That done, Splinter poured the water and clasped his hands as if in prayer.

The chant felt almost familiar as Splinter closed his eyes.

He was so focused on the chant he doesn't notice the water start to glow and move to encompass the markings…or the children gathering behind him.

In fact, he only realizes what is happening when one of the children, Donatello, grabs his robe and tugs, causing him to falter and mistime the chant.

"Dad, what's going on?" It was Donatello, Splinter realizes as the portal finishes and he stops the chant.

The children move toward the portal as Splinter tries to call them back.

Lupa excitedly grabs Splinter's robe and pulls him with her, surprising Splinter with her strength.

He doesn't even have time to protest as the children go through the portal, Asami only going after her siblings to hopefully bring them back, but they all crowd through the portal nearly at the same time, resulting in chaos as the portal fades and they are left careening down a wooded hill, and before Splinter can stop himself, he cracks his forehead hard against a low-hanging oak branch. Black consumes his vision and he knows no more.
