Roll is a humanoid Robot Master created by Dr. Light to be a housekeeper. Her dream is to one day open a hospital to help people in need. Roll is shown to be sweet, kind, and optimistic. She is a caring individual with a big heart. She doesn't fight Robot Masters as much as her brothers, but she does if she has the chance. She is supportive and compassionate, especially to Mega Man, Proto Man, and Dr. Light. "I don't know why she was so mean to Auto, maybe she's just strict when in charge?" - LisVi
