Roll (Japanese: ロール, Hepburn: Rooru) is a fictional gynoid in the Mega Man video game series and its spin-offs. A housekeeper robot who acts as a little sister to Mega Man, she was built by the genius scientist Dr. Thomas Light, and parallels Astro Boy's Uran. Her name forms a "rock and roll" pun with Rockman, who is called Mega Man in Western territories. Her prominence in the series has increased over time, with the remake Mega Man Powered Up making her a playable character. Fans have also frequently modified previous games in the series to insert her as the main character.
