This is a series of one-shots based on the 2012 version of Teenage Mutant Ninja Turtles. Most, if not all, will revolve around Mikey. There is a lot of brotherly fluff so be warned. I should specify that this is only including 2012 and ROTTMNT, as I've never seen any of the other incarnations. Edit April 21, 2020: Now adding ROTTMNT! Most ROTTMNT one-shots, if not all, will revolve around Leo. EDITED ON 08/20/22

When Raph and Leo are injured after a failed attempt to save them, Mikey is left with overwhelming guilt. But what if Mikey's episode of self-blame resulted in something much more severe? Will they notice when the youngest breaks down? ⚠️t/w - addiction, overdose, suicide mentions

This story is dedicated to my favorite and only little sister! After an accident in Donnie's lab, a table full of chemicals gets dunked onto Leo. When nothing happens, the brothers decided it best not to inform Donnie of this development. This proves to be a mistake, as the next morning they discover the oldest turtle - is now the youngest? Raph and Mikey are now placed in charge of Leo while Donnie works to make a cure. Mikey's incredibly ecstatic about the prospect while Raph is far less so. Unfortunately, now that he's the oldest, Raph knows it's his responsibility and agrees to help watch him. Besides, how much trouble could little Leo be? *Cover crafted by me; cover art not mine* All Highest Ratings #10 and Under: #1 in Leo #1 in Leonardo #1 in Splinter #1 in tmnt2012 #6 in Raph #6 in tmntfanfic #7 in Karai #7 in Michelangelo #9 in Donnie
