Summary
A portal mishap results in the turtles and April being transported to a whole new world. One full of vikings and... dragons? Well, maybe mutants don't exist here, but a different type of reptile certainly does.
A normal morning flight ends with Astrid in the freezing ocean, and Stormfly in the hands of dragon hunters. Whilst on a mission to rescue the captured dragon, the riders stumble across another prisoner! One with a strange accent, strange clothing, and even stranger story. Maybe 'turtles' are just what her tribe calls dragons?
Now, to find the turtles, stop Dagur, save the imprisoned dragons, and get everyone back to their proper homes in as few pieces as possible.

Wait For It by Cimmerian1275

Summary
During an ill advised trip to the Hidden City below NYC, an oozesquito meets an unfortunate end and changes Donnie in more ways than one, forever impacting his universe.
"Donnie ghosted out a free hand, hovering it over the pale purple and striped feathers that mimicked the markings running down his biceps. Equally horrified and fascinated, he gingerly brushed the pads of his fingers over the wing, recoiling like the touch burned when he could feel both surfaces of contact simultaneously in a horrifyingly real fashion.
His eyes drifted to the intricacies of the feathers, the biologist in him appreciating the marvels of nature and the ingenious design and how they're structured. Can feathers and wings still function at this scale?"
Tldr: Donnie gets double mutated and tries to cope :D

Summary
Gio had fallen into their lives at a point where the safety net had more holes than threads to hold. He was young, had the signs of a life hard won and fought through, but he tried. Absorbed absolutely anything his family would give him, even when it was nothing at all. Dark eyes, taking in any and all of the light he could just to find himself.
It was a tragedy in three parts just to watch him thrive off wavering candlelights and embers, wandering around the halls like a detective finding hints of some past crime.
Mikey squares himself. Finds that thread left in him that’s farther and farther away every day. Gio deserves the light, he can make some for him. He can.
Or: a series of standalone oneshots about Giorgio Hamato finding a home, getting adopted, and being loved back--not necessarily in that order. Set in both timelines.

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
The sun was clouded by the dust filled sky, the ashy cloud of smoke framed the technodrome while it slowly drifted from its original position, chunks of its Hall had ripped off and were now colliding with nearby buildings and the empty streets of the recently invaded New York.
Donnie stood there, his body firmly planted on the ruined ground of staten island, gazing up at the clean slice taken through the ships top, not even bothering to care about the cropped ship, more then the faded outline of the portal once there. His twin. Gone? Like that? Just.. Instant, it hadn't even set in yet, no realization past his glazed over eyes.
Gone?.. For real?.. No.. This has to be a.. A joke.

One mystic laced explosion later and he's hearing voices of people that don't exist and they keeping asking him questions he probably shouldn't answer because interacting with your delusions probably isn't a good thing.

You know how in Rise, Donnie breaks the fourth wall sometimes? Well I'm taking that a step further and now people in the comments can ask him questions or just talk to him in general. Asks start in chapter two.
