Summary
When Casey accidentally leaves a future device behind in the lair, the turtles do what they do best: press the button.
What activates isn’t just advanced tech, but a security AI built from a future version of Donatello. Older, sharper, and deeply unwilling to believe that the people standing in front of him are real.
As containment protocols engage and paranoia escalates, Donnie is forced to confront the kind of version of himself that only exists after years of war, loss, and impossible choices, and what it means to become someone who survives by assuming the worst.
Or: Casey forgets something. Mikey presses a button. Everything gets complicated.

Summary
The world ends. The Krang win. Leo failed.
It was supposed to be on Casey's shoulders (and his shoulders alone) to go back and make sure the invasion never happened in the first place, but apparently his student had a little more inherited stubbornness than he'd thought.
(Leo ends up in the past. This changes some things.)

Summary
The Kraang are ready. Their plan to take over Earth has been running smoothly for centuries, and they only have the final steps of their plan left to finally gain their second home... Until the turtles come around. No matter what they do, they can't seem to defeat them. The mutants knock down every tower they build and all the progress they make, and now the Kraang are getting desperate.
But they have the technology, the interdimensional portals, and the mind control devices... and so they hatch a plan. It's a plan that cannot possibly fail. After all, who would be better to defeat the turtles than the turtles themselves?
