Summary
After being kidnapped by a mysterious organization, the Hamato brothers are separated and experimented on—physically, mentally, and emotionally. Each is told the others are gone.

Summary
Leo was sick of having to share everything with his brothers. His hoodies, his comics, his personal space; even his medical equipment sometimes went missing!
Yet, they kept calling his selfish and inconsiderate, despite all of the sacrifices he had made over the years all for them. Speaking of privacy, those years of learning to hide his thoughts were starting to pay off, since now no one could tell when he was deceiving them, or keeping secrets of his own.
So, of course he can't be blamed when he discovers a secret room underneath the lair, one that he can own and have all to himself.
Or, Leo finds a new room that he then owns and keeps a secret of for years, until his brothers start questioning his disappearance.

Summary
After Leo is saved from the Prison Dimension, his brothers quickly realize that more happened than they had realized. Leo would get random bouts of feral bewilderment and had random triggers that had not been there before. What had happened to him?
Gaichū doesn’t understand what happened. One moment he was in his home, running away from a beating from Master and the next… well… the next he found himself in a strange new world surrounded by new enemies who seem to know him. Now he has to learn to navigate the peculiarities of this new place and hope Master won’t find him.
Peculiarities such as gravity.
And light.

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
"You're pushing me away just like you always did!" Raph accused, earning him a scoff in contempt. But he went on anyway. "Why!? Why is it so hard for you to admit you're hurting too!? What are you so afraid of!?"
Leo opened his mouth as if to answer. But changing his mind he turned around to continue walking down the street. Raph followed, matching his slowed pace while Leo didn't have the energy to deal with another yelling match right now so listened instead.
"I want things to go back to the way they were before with us."
No response, Leo kept on walking.
"Or if they can't go back that way there's nothing saying we can't work on this, together."
For reasons he didn't quite understand Leo walked straight past his apartment building, continuing on down the wet New York street.
"I don't want to leave things they way they are between us. It's been too long, don't you think?"

Summary
Leonardo released that pent up anger by lashing out at the younger version of himself: "The only reason we're in this mess is because you're a cocky, overconfident little brat who can't stop goofing off and refuses to take anything serious!"
"Why did you take me outside in the first place if it's so dangerous out here we could wind up dog meat just going for a little stroll!?"
"Because I wanted to show you what your mistake cost everybody!"
Those harsh, clipped words cut Leo to the core. His shoulders dropped down along with that scowl on his face which was replaced with a frown, and his voice radiated sadness when he asked: "You're not talking about me using my portals, are you? This..." he looked out through the opening of the small cave-like structure they were hiding in, staring at the redness to the landscape that wasn't from the setting sun but rather by some sort of deathly apocalypse caused by these 'krang' Leonardo had mentioned, and continued: "...this is somehow my fault."

You can't die in the prison dimension, Leonardo discovered one fateful day.

Summary
Relishing in his victory, Hawk paused applying the bone-chilling pressure just long enough to grin at Leo's face and coldly toy with him by saying: "You can take a break, if you just tell me that it hurts."
Leo's head made an audible *bang* on the wooden surface behind him when he flung it back to cry out at the top of his voice, trying to scream 'IT HURTS IT HUUURTS!!!' but only able to get out muffled nonsense because of that cursed gag.
Hawk and Ox laughed out loud at his misery.
Blood drizzled down from the open cracks in Leo's plastron, then the tightening pressure resumed...
