April O'Neil is a Human/Kraang hybrid who is a friend of the Turtles.
Not the typical teenager, April is more comfortable and shy around the Turtles than around her high-school peers. She always knew she wasn’t meant to live a normal life, but now that extra-dimensional creatures bent on world domination have kidnapped her super-intelligent scientist father, things will never be “normal” again. She also shows to be stubborn at times like when the Turtles infiltrated into T.C.R.I, she constantly insists on coming into TCRI with the Turtles even though it's very dangerous and she's not a very experienced female ninja.
