Summary
Being the leader has always put Leo in the spotlight — but when the Foot Clan realize taking him down is the fastest way to break the turtles, Leo becomes their number-one target. A mystic curse leaves a mark burning across his shell, designed to weaken him with every fight, and the enemy taunts that if the head falls, the body will follow.
But the Foot didn’t count on one thing: Leo’s brothers don’t crumble without him. They rally, they fight, and they protect — because no one gets to break Leonardo. Not while Raphael, Donatello, and Michelangelo still stand by his side.

Summary
Leo was trained to lead—but no one trained him for failure.
After a mission goes wrong and one of his brothers ends up hurt, Leo spirals into self-doubt. Just when he thinks things can’t get worse, Splinter makes a shocking decision: Leo is no longer in charge.
Someone else will wear the mantle of leader. And for the first time, Leo has to face who he is when he’s not holding the team together.
Without the mission… without the mask… who is Leonardo?Based in the 2012 universe!

.Tamora. If thou didst know me, thou wouldest talk with me.
Titus Andronicus. I am not mad; I know thee well enough:
Witness this wretched stump, witness these crimson lines;
Witness these trenches made by grief and care,
Witness the tiring day and heavy night;
Witness all sorrow, that I know thee well

Is not thy coming for my other hand?-Titus Andronicus, Act 5, Scene 2

Suddenly he becomes very concerned and then the others find out, and then they have to embark on a spirit/meditation mission to free him from mental chains with different versions of their youngest brother. And then they have to confront a lot of things about Splinter. In simple terms, everyone needs some kind of therapy and something gets done about it.

Summary
Michelangelo is a turtle that's like a magnet to all kinds of messed up substances and drugs.
Since a young age, he would eat whatever was in front of him, was it edible or not: worms and algae, chewed gums on the ground, Donatello's dangerous chemicals (that somehow smelled so, so good), Ice Cream Kitty's neapolitan flavored fur, gummy bear and pepperoni pizza, the Dimension X worms' juice, you name it.Somehow he was still alive.
Donatello theorized that it might be because of the mutation.
Leonardo hesitantly said that it's kind of a talent.
Raphael simply stated that he's just as careless as lucky.
And Michelangelo himself didn't really care as long as he had something to eat.Then, it became a problem when he started getting into his system things that would, in fact, affect him greatly.

The moonflower blooms
Fleeting grace on this rooftop—
Glimpse of white on steel.[2017]

Will you mourn with me?[2020]
Caught inside his war,
Reluctant wakizashi.
Know that I loved you.or
TMNT 2012 Leorai where the two dummies are NOT siblings. Follows them through around 10 years of life (15-25).

Many short chapters since this is epistolary, but I will post several at once!Spoilers! Summary for arc 3 (after the main series events):
Karai takes over the Foot clan and moves to Japan. Leo always wanted to visit Japan.
Right when things finally seem to be falling into place, it gets messier than ever before. -
