After being with the turtles for a year, Splinter was searching for food on the surface when he came across a young four-year-old girl, abandoned and alone. He took her back to the lair, where she fell in love with the young turtles, treating them as her younger brothers. 

As the turtles turn fifteen, and their big sis Pepper goes on eighteen years, Splinter finally lets them go to the surface. What happens when they run into the Kraang and meet the Shredder? Will Pepper find out who her real family is?

Harmony was found by Splinter shortly after he and his four pet turtles became mutants, she is only a month younger than Mikey so the five of them grew up together all raised by the great ninja master. Harmony however refused to learn how to be a ninja because she isn't human or a mutant at all. She has amazing powers and a single punch from her could kill anyone so she just decided to become her brother's secret weapon. After having many adventures with her brothers she learns something about herself that will change her life forever.
