Fanfics
1. Finding my way home(and moving forward)
Out of sheer curiosity, Leonardo and Donatello looked up, and there it was.
A portal.
Had the Universe really taken pity on them? Had it really heard his desperate prayers for one more chance?
It was not like the ones they had seen before, it was an irregular circle made up of several shades of blue, completely different from the perfect and symmetrical pink triangles of the Kraang.
Leonardo and Donatello looked into each other's eyes for a few moments, "Should we go in?" Donatello asked, almost shouting, drawing the attention of the others, who quickly turned to the portal and to see each other, then the two brothers in question.
"It's our best bet, and our only chance," replied Leonardo.
Or rather, with the 2012 kids' home gone, they end up in the Rise verse after a strange portal shows up. Therapy is needed, and start the slow process of healing from their trauma.

2. Strawberry Cookies:
"Mikey here was just about to tell me what we could do to cheer Raph up while he's sick," Donnie says. "Mikey continue?"
Now that Mikey had both of his older brothers attention, he grins. "I was thinking we make strawberry cookies!" He does his jazz hands as he says this and is met with looks of something that he can only put as disapproval. "What?"
"You do know that everytime that we have tried to make it-" Donnie starts.
"We mess it up and Raph has to come in and save our butts from burning the cookies?" Leo finishes, "What would be different this time?"
Mikey huffs, "We are doing this so we can cheer him up and to prove that we can do something on our own!" he says, "That's what got Raph sick in the first place!"
Or rather, Raph gets sick after helping his brothers recover from the poisoned pizza puffs. Mikey, Donnie, and Leo take a shot at baking cookies for Raph while trying not to burn their kitchen down.

3. Chicken Fried Rice:
“I only poured in half a pot of rice,” Donnie complained.
Mikey stared at him, really stared at him before he spoke. “You do realize that rice expands when cooked right?” he said, “You do realize that?”
Donnie was silent, looking away from Mikey.
“Donnie!”
Donnie makes chicken fried rice. Mikey watches over. Shenanigans and brotherly fluff ensue.
one shot in which Donnie is in the kitchen, cooking rice and Mikey, Mikey is positive he should have gotten Donnies braincell.
(One shot, complete)
4. Tea Time with Hortense and Patty:
"Sooo," Raph starts. She's always been weird with awkward silences. "Are these grandma kinning hours?"
"Grandma hours!" Mikey exclaims excitedly. "Grandma time!!!"
"Ah, if it isn't our favorite girl and her little brother!" Hortense tilts her head over in their direction slightly. "Are you going to join us? We were just about done arguing," she says.
---
Today is Tea Time. Two old ladies have a tea party, one of them forgets to bring the food, and they are joined by Mikey and Raph. A good time is still had.
(One Shot, Complete)
5. One of those Days
When Donnie woke up this morning, he woke up with the familiar thrum of anger and irritation running through his body with more intensity than normal. Rubbing the crust out of the corners of his sleep-addled eyes, he jerkily grabbed his phone and turned off the alarm. It's one of Those Days, Donnie noted. Those Days where Donnie isn't capable of handling Mikey's over-enthusiastic optimism or Leon's chaotic trickster nature. His safest bet is to hang out with Raph, his calm and mellow demeanor always helped calm down before Donnie went on a rage fest and say anything he couldn't take back.
Or, Donnie and Raph help each other out, balance each other, and make things a little less difficult.
(One Shot, Complete)
6. Gift Hunting:
“It’s Leo. Tiny Leo,” the voice answers. “I need your help with something.”
“What is it?”
“I can’t say until you say yes first,” Leo says. “It’s really important though.”
Angelo is silent, weighing his options. He could say no, he really could-
“Please, Angelo, you’re the only one who can really help me with this,” Leo pleads.
Rather, Angelo and Leonardo go out in the streets of New York to help the blue banded turtle find gifts for his brothers' sixteenth mutation day. Bonding and fluff ensues.
(One Shot, Complete)
7. Aftermath:
“Raphie bear?” Mikey called out, gently tapping Raph, with relief washing him when Raph turned his head to face him. “What’s the matter teddy bear?”
“Th-thi-this doesn’t feel real.” Raph stuttered out, his voice cracking as a sob broke through. “I’m not really here. Neither are you and everyone else. I’m still alone with Draxum and his minions. No one’s coming to save me because I was stupid enough to get captured and no one wants such a worthless turtle like me.”
In which Raph was kidnapped and tortured by Baron Draxum and his family has to deal with the aftermath of it.
(One Shot, Complete)
8. To Be the Eldest
Donnie, the second youngest in his family, wishes he was the eldest for once. Then one night, Donnie gets his wish granted and now he was three small turtles in his care.
Donnie adjusts to being the eldest, comes to some realizations, and makes a promise to his (now) younger brothers.

9. Wanted: Snaggletooth
Dr. Noel bent down on his knees in front of Raph, a manic smile that showed too many teeth coming about on his face speaking of pain and suffering that has yet to come. He stretched out his hand towards Raph’s face, placing a thumb under his mouth, pressing into his snaggletooth. “Beautiful. Just as I expected,” he crooned, pulling out a syringe and injecting it into Raph’s neck, pushing the contents of the syringe into his system.
Raph’s eyes fluttered as he started losing consciousness, watching through hooded eyes as Dr. Noel's smile grew even wider, with his last thought right as darkness consumed him being that he hoped his family would find him before it was too late.
Post S2 Finale, Dr. Noel remembers Raphael, his snaggletooth, and manages to find and capture the red masked turtle. It doesn't end well for Raphael.

10. Dimensional Differences:
They bow. Not like one of those pretentious bows like she would do at Yokai parties and not like the ones she would do with her brothers when they hosted tea parties. They bowed deeply, heads stopping at her stomach, one hand closing around their fists. This spoke of respect and honor.
And that unnerved her a little bit. Why are they bowing so deeply?
“Thank you,” they said in unison. It’s unnerving to April and she felt the uneasiness coming from her brothers too.
“Why are you thanking me?” She said finally, voice sounding foreign to her.
“You saved my life?” Baby Leo said slowly, voice tinged with confusion. “That was an honorable thing to do?”
April blinked, “It shouldn’t be considered honorable for doing what any big sister would do,” she said. “That’s not honor, that’s just being a good older sibling.”
In which April, Sunita, Casey, and the turtles end up in the 2012 verse after a mishap with Leo's ōdachi and stay with the 2012 turtles until they can go home. They find out a lot of things that don't quite jive with them. Some things are the same, some things are different and they're not quite sure how to handle those differences.

11. Mind Meld Part Deux:
“Oh thank Galileo that you all are back to normal!”
“What do you mean we’re back to normal?” Raph questioned, pulling back from the hug. Mikey and Leo also pulled back to stare at Donnie. “We’ve-we’ve always been like this?”
Donnie went quiet. He shouldn’t have said that.
“Donnie, what did you do?”
The brothers found out about Donnie’s Mental Intelligence Reprogrammulator. Arguments are had, words are said, words that tear a rift between him and his family, and it’s up to Donnie to earn his brothers’ forgiveness. The only thing is, will he get it?

12. I'm a little kid and so are you(don't you go and grow up before I do):
The 2003 turtles somehow, someway ended up in the Rise verse, with Rise Splinter and his turtle tots, and stay with them while the boys try to figure out their way home. 2003 Raphael got attached to his tiny counterpart the moment he laid eyes on the tot. (Raph centric)
(Rise/2003, Work In Progress)
13. Dimensional Self-Isolation
Post S2 Finale, Raph finds himself trapped in the 2012 universe and has a difficult time coping with all of the differences that this world has in store for him. From new villains, unfamiliar familiar faces, and the way the 2012 boys and Splinter treat each other and him, Raph has a heavy plate on his hands during his long term stay.
