Rowan is a cute little girl who in a way resembles Isabel. She's 10 years old, and ridiculously smart. Though she isn't old enough to go past the walls, she's known as the Survey Corps mechanical child. She's an orphan who's taken care of by the whole regiment, and tends to be very techy when it comes to mechanical devices. Her specialty is fixing the 3DMG.  She needs a young and sweet voice. But she needs to kind of have a raspy tone, kind of like Vanellope from Wreck- it- Ralph.
