Raphael comes into contact with an aggressive strain of Mutagen that should have killed him. Instead, he's changed. For better or for worse, Raphael has gone through a second mutation, and his brothers race against the clock to try and change him back. Or die trying.

There's no true weight to emotion anymore; rather, an emptiness is spreading throughout his chest and he's not sure now if he can, or even wants, to stop it. TW: Depression focus

Michelangelo has three overprotective big brothers, some questionable friends, a burgeoning need to make himself useful, and a lot of growing up to do. (IDW/2K12, Human!AU) 2015 TMNT Fanfic Competition Winner: 1st Place "Best Michelangelo".

Right away, Yoshi recognized that his little box turtles had become more than just corner store pets. They were children, now, almost human; with wide, bright eyes and dimpled faces. It took him longer to recognize that they were his children. (2k12, oneshot.)

"Let me give you some advice," Leo said, still so quiet and cold, nothing like Raph had ever heard before, his blue eyes burning like fire. "Don't ever lay a hand on my brother again. I don't care who you are. I don't care how big you are. All I care about here is him." (IDW/2k12, "Problem Child" extra, oneshot.)

"I don't think I want to ask about the symptoms of this illness." "Well, even if you wanted to, I wouldn't have an answer for you." Another laugh. "All I can say is that sleeping doesn't come as easily as it used to." -The hospital AU that no body asked for. I realy hope you enjoy, and I'm sorry.

She would live for a million years, but she'd never forget his laugh. (Renet/Mikey, oneshot.)

"I lift that much so I can pick my brothers up when they fall, lil' brother." Mikey decides to have a go at his brother's barbell machine and not only breaks it but injures himself in the process. Raphael is furious but not for the reason the youngest turtle thought. OneShot. Raph and Mikey brother fluff. Rated T for very minimal swearing.

Finding Bucky is the easy part. He's broken and terrified and a shell of his former self, but Steve knows he can save him. It'll just take time - time and patience. And many sleepless nights. Spoilers for Captain America: The Winter Soldier. No slash, just friendship and LOTS of h/c.

Tony can't help but notice the far away look on Steve's face. The visible pain and loss. It wasn't right and giving Steve back everything he'd lost was the right choice. The right thing. And honestly Tony didn't do the right thing near enough... prompt fic: time travel, WWII, Steve/Tony

Donnie's the smart one, but sometimes he misses the obvious.

It took all of five minutes for Sakura to fall in love with Sasuke. It took Sasuke years and the pain of death to realize he loved her back.

Leonardo is somewhat spoilt for entertainment when a run-in with the Purple Dragons leaves him temporarily incapacitated. Family schmoop.

All he wanted was some peace and quiet... but perhaps that was asking to much considering he lived with three younger brothers who were slowly driving him mad. And being cooped up for a week didn't help matters at all, either.

Leonardo comes to discover more about himself and his most antagonistic brother as he helps Raphael recover from an injury. Slash. Challenge fic. COMPLETE.

When Raphael is captured and traded as an animal on the black market, he is forced to question his pride, his strength, and what it really means to be human.

An alternate outcome of Eighteen Minutes. When a brother is attacked, the entire family is wounded. Sometimes, healing is harder than staying hurt. Winner of Best Tragedy/Angst in the 2007 TMNT Fanfic Awards.

COMPLETE! Donatello's skills are put to the test. Can he find the antidote that will save his brother, or will Raphael's death be on his hands? Rated M for language. PLEASE R/R!

Always put the customer on hold. Right off the bat. Takes some of the fight out of them, you know? Shows 'em who's boss! A 2007 CGI Movieverse oneshot from Leonardo's POV exploring the theme of 'support'. Heavy on character study and brotherly interaction

It's easy to fight beside your brother. It's harder to miss the fight altogether and be left to pick up the pieces. Raph must recover from a fight he fought alone, and it may be too much for his brothers to help with. Warning for slash.

Having time to kill is a marked change for the family, but it’s growing on Raphael. Rated for slight language.

Once a brother, always a brother, even in the wee hours of the morning. Pure fluff.

Donatello finds out that some unsolicited brotherly affection is often the best kind of pickmeup. Just a bit of fluff, and I do mean fluff. Rated for a smidgeon of language.

Raph and Mike come under fire. Glass shatters, the world turns upside down...

Is it worse to suffer in protection of those you love, or to watch someone suffer to protect you? Leo, Don, Mike, and Raph struggle to recover from a horrifying captivity. Now completed!

Raphael is losing himself in growing doubts about his place in the world, and it's only made worse when he attracts the notice of a new criminal element in the city. His brothers come together to help him before it's too late. COMPLETED!
