Lidwina Simmons
Having a disease that shuts down her voluntary motor functions, she's dependent on a robotic body to move. Of course in order to support her it has to be a large one but they found out a way to make it work for her. The compartment that contains her actual body is surrounded by cushions because she figures if she's going to be this big she might as well be soft.

She's a cheerful girl who's eager to explore the world now that she can.
