Set after 'Mutagen Man Unleashed.' Determined to keep his promises to change Timothy and April's father human again, Donatello pushes himself beyond the point of exhaustion while working nonstop to create a retromutagen. It's up to Donnie's big brother, Leonardo, to stop the genius turtle from sacrificing himself and help him see his own self-worth.

Set after 'The Fourfold Trap.' After escaping Karai's deadly traps, the turtles return to the lair, hoping to put the awful events of the night behind them, but there is one brother who cannot forgive himself for what has happened. Consumed by guilt, Donatello makes a rash decision that puts his life in grave danger. The brothers race to save him, but will they be too late? *Cover art by AyaShanti ⭐️TMNT Universal Fanfiction Competition 2016 Winner - Most In-Character Leonardo (first place) and Most Exciting Action/Adventure (third place)⭐️

After a near-death experience, Donatello is reprimanded by his older brothers for his actions, leaving him to question both his self-worth and his place in a family of more skilled ninjas. As a result, the turtles may find out what life would be like if they lost a brother. *Cover art by Flaux. ⭐️TMNT Universal Fanfiction Competition 2016 Winner - Most In-Character Donatello (first place), Most In-Character Raphael (first place), Most In-Character Michelangelo (first place), Best Original Character (first place), Most Exciting Action/Adventure (first place), Most Intriguing AU (second place), and Most Intriguing Villain (third place)⭐️

Searching for a gigantic, blood-thirsty mutant bat is hard work. Creating an antidote for said bat was even harder, especially with three impatient brothers and indignant best friend- Donatello would know. With little time and motivation left, Donnie finds himself plagued with guilt over not being able to cure April's father. In an attempt to fix what he had broken, the genius inadvertently puts himself in harms way. Who knew one simple, solo mission could change so many things? An AU. I've watched the 2003 episode of TMNT, 'Good Genes' a million times just so I could write this story. I love the episode and I'm committed. Love you all!!! <3

Just some headcanons I've found and wanted to share it with y'all!!
