Roll (ロール, Rōru) is a kind-hearted humanoid robot created by Dr. Light to be a housekeeper, helping around Dr. Light's Laboratory by cleaning and cooking. Roll is like a younger sister to Mega Man.[1][2][3] Her dream is to one day open a hospital to help people in need.[4][5]
Roll is one of the few female characters in the original Mega Man series, and the only female humanoid robot until Plum and Splash Woman were introduced into the series. She is perhaps one of the most special and well-known characters in the entire Mega Man series, and remains a fan-favorite to many. She is especially well known as the first female character ever in the Mega Man universe. She is also special in a sense that she, with her counterparts Roll.EXE and Roll Caskett and appearances in other media, combined, has made the most appearances of any supporting character in the Mega Man series as a whole.
