Summary
They’re recovering. Slowly. Messily. But they are recovering. And for the first time since shouldering the weight of leadership, Leo feels free. Free to breathe. Free to exist. Free to mess around, laugh, explore, and actually enjoy being alive without the constant dread of messing up again.
Sure, he threw himself into the Prison Dimension. Sure, he sacrificed himself to keep the Krang contained. But it wasn’t some suicidal gesture, god, no. It was just the only plan that gave them a real chance. And he trusted his brothers. He knew they’d pull him out. That trust is what kept him moving. He lived. He survived. The city is safe. His family is alive. The Krang are gone.
So… why can’t his brothers see that?
OR, All Leo wants is to be trusted again. (And to get his privacy back.)

Summary
Leo’s twin, other half, best friend, mate. Leo’s partner had been locked away in his lab for two, going on three weeks, so absorbed in his projects for eighteen days that he hadn’t had any time for his lover.
So yes, Leo was irritated. Hell, Leo was a little bit angry, if he was being honest. But if he was being honest, he’d have to admit that, more than angry, he was lonely and sad. He felt neglected. So he was choosing not to be honest, even to himself, and would only go so far as to admit that he was irritated.

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
Donnie always imagined that after Leo came back, everything would be okay again. Instead, his friendship with Raph stays rocky, his schedule gets even harder to manage, it still feels like he's the only one looking after Mikey and now there's a stranger living with them. It's getting hard to imagine how he could get any more stressed.
Then he wakes up with an awful headache, restrained, in an unfamiliar laboratory. Being restrained or experimented on would be bad enough on its own. Add to the mix that lying on the lab table for days and weeks is the first chance he's had to process everything else that's happened in his family--well, it's not a happy mix.

Summary
It's been two years since the Superfly incident and the boys have finally recovered. Well. Most of them at least. Leo had always been the anxious one, never breaking rules, scolding his brothers, and never wanting to try new things. But now? Leo was anxious about himself. He didn't like the bubbling feeling he got when Raph and the others teased him. The urge to just punch him and tell him to shut up was something he was ashamed of thinking. And yet it happened over, and over again. The same boiling feeling. The same anger that might just push him away from his family.
PT.1 of the angry Leo series! (The stories won't be connected but all include Leo having a temper similar to Raph's)
(This isn't written in the POV of Leo, but the wording is influenced by him. So if he is annoyed by something the text would say "and that same annoying beeping noise every five fucking minutes" instead of "the same beeping sound every five minutes".)
Only "warning" is cussing igSeries

Summary
If you would ask Leonardo how his month has been, hectic would be a good answer.
Leo’s hand strongly gripped the counter, eyes looking down at his battered body. Because they won, didn’t they? But Mikey’s arms won’t stop shaking, and Donnie grips his shell as he sleeps at night and Raph-
The slider curls up his fist and thuds it on the table because he shouldn’t feel afraid, and he knows his brother won’t hurt him but-
***
If you ask Leonardo how he was coping after the invasion, he would say he’s been fine. But he can only tell himself this for so long before he reaches boiling point, and where his fears catch up to him. -
