Summary
Lavinia finds herself in a world wholly unlike her own and realizes that making everything go back to how it used to would be much harder than previously expected. Still, she was a Hamato.
And that means she would not give up so easily.
If only the turtles in this world would stop trying to catch her, then maybe she could actually get some work done.

Summary
Months after the Krang invasion, Donatello begins to experience severe shell irritation. When tests reveal leftover Krang matter lodged deep in his shell from the Technodrome explosion, Leo and Draxum perform a delicate extraction procedure to save him. Recovery seems promising—until Donnie collapses weeks later and begins coughing up blood.
After an emergency evaluation, Draxum delivers the devastating diagnosis: a rare, aggressive form of cancer, likely triggered by the Krang residue. As Donnie undergoes harsh treatment, Leo—driven by guilt, love, and fear—digs into his medical training, determined to find a cure. He refuses to let his twin slip away, even as Donnie weakens by the day.

Summary
A year after the Kraang invasion, Leo still struggles with his failures and the weight of leadership. Determined to grow stronger, he makes the painful decision to leave for Japan, training to become the leader his family deserves. But after a year, a deep unease stirs within him through his ninpo. He returns home—only to find the lair in ruins, his family gone, and the Foot Clan's insignia flying over what was once their home. Believing them dead, Leo wages a ruthless one-man war against the Foot, hunting them relentlessly.
But his family is alive—held captive by Shen, the new, ruthless leader of the Foot. A cunning and powerful mystic, Shen seeks to steal the Hamato Clan’s ninpo, intending to ascend beyond mortality and reshape the world in her image. With the Foot under her control and power within reach, she will stop at nothing to claim what she believes is hers.
Unaware of the full extent of her plans, Leo has one goal: to destroy the Foot and make their leader pay.

Summary
The smart lock on his front door trilled, and Raph’s rant instantly cut off, the room falling deadly silent. Leo locked eyes with his brother, and it was clear that Raph hadn’t been expecting anyone else; a quick glance at Takeshi confirmed the same. Like a well-oiled machine, they prepared for an attack—Raph slipped on his brass knuckles, Tiger Claw drew his gun from its holster, and Leo deeply regretted not getting one of his guns from the bedroom when he had a chance. Leo watched, unbreathing, unblinking, as the front door swung open.
Not an enemy.
Hamato Saki. Head of the Hamato family, a subsidiary of the Tatsuo clan. Second in command of the Tatsuo clan, just under the kumichō. Both Leo’s blood father and his oath father.
In a world where the Hamato clan is a yakuza family and the turtles are human, Saki succeeds in killing Hamato Yoshi. Hamato Shen leaves for New York with Donnie and Mikey—leaving Leo and Raph behind. Over 15 years they became the Hamato family's most deadly members, until an assassination attempt sends them out of the country to protect a barely-remembered mother and brothers.

It was maddening, but he wouldn’t scream. He wouldn’t scream because he was a leader. And a leader wouldn’t show any weakness no matter how crushing holding the weight of that title could be.
Even when he failed at that not so long ago.
He—he couldn’t let that happen again. He couldn’t.

Summary
“It’s a nickname. Short for Donatello.”
“Heh.” He quirks a smile. “Kinda a coinkydink ‘cause-”
“Hamato Donatello.” Leo’s head shoots up and the turtle looks back. “My brothers are Leonardo, Raphael, and Michelangelo. They have nicknames too. Mikey, Raph…” He tilts his head, urging, “Leo.”
Leo stares, looking for any sign of deception. The turtle keeps talking, almost as if he’s trying to get the words out before his brain can catch up. “We’re a team. We fight crime and save people. I have a father. We call him Splinter. He’s a rat. Used to be a human. Adopted me and my brothers, taught us ninjitsu.”
Leo’s paralyzed. He waits for the snickers, or for the punchline.
The turtle does not shirk away, eyes bright with the maniac look that Donnie gets when he proves a theory correct and is dying for a single person to acknowledge that he’s the smartest being on planet earth.
“So. Leo.” It’s conversational, calm, eager. “What’s your family like?”
(Or, A crossover where 2012Donnie is sent by Za-Naron into the Prison Dimension and joins RiseLeo during his stay. ✨ And they bond. ✨)

Summary
Merging with a Technodrome has life altering consequences... or more specifically life ending ones. While dying is uncomfortable, awkward, (and a bit of a chore,) the idea of his family continuing on without his technical skills is unbearable. Literally the pineapple on his pizza. The concept is so grating that Donnie will do anything to make sure his family is taken care of once he's gone: Even if it means transplanting another version of himself from another timeline to take up the job opening.
In Casey's Timeline his Donatello died in an extremely convenient-to-obscure way. A body was never found and his death was never explicitly witnessed. The only reason they know Master Donatello "died" is because his circumstances were "inescapable" but Donnie is sure he can put up some air quotes. Removing this other Donatello from Casey's Timeline wouldn't change the future that has already happened or create a new timeline. So what's the harm in taking someone from a timeline that doesn't need them anymore?
Or: Donnie needs to replace himself before he dies at the young age of seventeen and Master Donatello becomes the candidate for that endeavor... by force.

Summary
“How old is he?”
Leonardo pauses his stirring. He half-expected a joke—an innocent little jab meant to lessen the tension thickly clouding the kitchen—yet Leo’s voice is quiet, serious.
So Leonardo turns around and offers the same air of calmness that the teen approached him with. Yet his chest constricts when he has to angle his head down low to meet Leo’s eyes, and an overwhelming sadness withers his heart as he takes in that young, bright-eyed face. Leo is a child, a baby.
And he’s going to cause the end of the world.
Or, Casey Jones goes through the time portal, but he’s a baby in Leonardo’s arms. And one traumatized turtle juggles being a new dad while trying to prevent a horrible future.
