Leo has managed to lose Splinter's thingamajig while playing Ping-Pong, portalling it into the Hidden City, now swearing that it's landed in a casino. Now, the turtle brothers, along with April, must devise a plan to get it back without April getting caught in the "no humans allowed" establishment. However, it doesn't seem like this is going to be an easy task, by any means...

Leonardo may have beheaded Shredder, but that doesn't mean he's gone. In fact, his soul is still very much alive, just trapped in another dimension, and now he's a different turtle's problem. (Rise and 2012 crossover. Mostly the Leos, because there's not enough of those two.)

The mission comes first. That's what Donnie always says, anyway. He also says he's fine. And Raph listens to him. But when the mission ends, Donnie is suddenly unconscious in Raph's arms with a broken shell. It's a race to get Donnie home and fixed, but the danger won't end even there. Because the mission isn't over after all, and Donnie will do everything in his power to end it.

It's past midnight on a frigid December evening, and April's just getting off of work, awaiting Raph's arrival so they can go do the one thing they've secretly been planning to do: ice skate.

Mikey accidentally loses his brothers because of an ill-advised wish, and he would very much want them back. If only he knew where to find them. 2012 turtles, Mikey-centric.

The time has finally come. They’re heading home. But there was a bit of an inconvenience.

Donatello's got a cold, but it's no match for April. Set early in the 2012 series.

There were worse ways to go, Casey reflected, than surrounded by family and under a sunset.

The Lotus Ninjas fights the Shadow Clan led by Lady Shade and her lieutenants Mira and Sierra as well as the mysterious Onis, and the mad scientist Sage Lincoln.

Leo dies and his family have to try and learn to move on.

Isabella awakens in a strange dream. Or is it a dream at all? She finds herself in a room and a person who claims to be her creator decides to speak with her. What do they want? How did she get there? Find out inside this oneshot.

The original version of The Fight for Mikey (a ROTTMNT x TMNT 2012 crossover) Chapter 8 "ROUND FIVE: Primetime & Doctor Disappointed"

Athena is trying to escape the horrors of her past, and a blue-banded turtle with a penchant for cracking jokes just might be her gateway to a happier life. But it won't come without its obstacles and memories that are better left forgotten. TW: implications of SA, not explicitly stated.

After Donnie suffers a secondary mutation from Bishop's viral outbreak, Raph loses control of himself and pins all the blame on Mikey, making him feel extremely low and not wanted in the family. Will Raph see the error of his ways before Mikey is lost to everyone forever? An alternate storyline in the episodes 'Good Genes Part 1 and Part 2'. Episode 3 of the 'I'm Sorry' series.

You can't expect to save the world and not have any consequences.

Early Season 3 fix-it fic. Trauma comes in all shapes and sizes, but no matter how it manifests, it's never an easy burden to carry alone. What happened during the three months Leo was in his coma? How did his family and friends cope while he was out? How did he deal with both the physical and mental trauma left behind by Shredder once he woke up?

Well, a friend of mine (FemLexLuther), my little sister and myself came up with this idea when Fem and I thought my sister did something that she didn't obviously do, but it was just SO funny [in our point of view] that we came up with the idea of writing these short stories. Now, Fem is doing her own version, while I'm doing mine. So, let's... GET INTO IT!

School. Work. Home. That was Kara Sharper's life to a T til certain mutant turtles barged through the doors of her work and turned her life upside down. Based off the 2018 Rise series. DonniexOC. Episodes will be skipped.

Raph wants to ask Leo something, but his plans are…interrupted

Eleven years ago, they lost a brother. Now, at sixteen, they must question if this is really true. Working under Aroko Saki with the only people he's ever known, Donatello has been taught to fight under the Foot's name. When he's introduced to three mutant turtles on a mission, questions arise that he cannot answer. (Donnie-centric. au. Foot. hurt. Shredder. torture. angst.)

I never thought my life would change like this so fast. I was just your average teenage girl with her own normal and slightly boring life. But after encountering a strange mosquito and following one of my classmates/friends down into the sewers, my life was about to change forever.

In a horrific turn of events, Raphael finds himself thrust into new responsibilities as Leonardo is killed in cold blood by their sworn enemy. The eternal guilt begins to gnaw at him as Raphael has to come to terms with his brother's death and accept Donatello as the new leader of the group. But he struggles to do so when he begins to hear his brother calling his name.

Donnie makes a deal with the Devil.
