I'm Not An Organ Donor by Crowdog

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.

Fate Has Bad Taste by LexLeo

Summary
Leo, 27 and still fated-one-less, had finally caved—signing up for one of those sketchy "Fate Hunting Consultation" services in a desperate bid for connection.
Then he showed up at work.
A new guy. Tall. Purple bandana. Sharp eyes and an even sharper tongue—like he’d been born annoyed at the world. And seriously? Kinda hot… in that I'd punch him then kiss him kind of way.
But Leo was sure of one thing: this turtle had zero charm, all ego, and absolutely hated his guts.
So when his heat hit like a freight train—sudden, violent, impossible to ignore—the universe really had a sick sense of humor.
Because the only person within reach?
Was him.
The grumpy purple pain-in-the-shell he couldn’t stand…
And who might just be his fated match after all.
(PS. This is my first story and I did not beta read this!! Also this is heavily inspired by "I can't believe You're my Fated Partner")
