Ruby Rose (Red Rose or simply Red) is the main titular protagonist of the anime-styled cartoon web series RWBY.
She made her first video game appearance in RWBY Grimm Eclipse and made her first fighting game appearance in BlazBlue Cross Tag Battle as a playable character and as one of the four main characters.
A Huntress in training, she was raised on heroic stories told to her by her late mother Summer Rose and dreamed of being a great Huntress just like her to help others in need. Trained to wield her custom made weapon Crescent Rose thanks to her uncle Qrow Branwen, her skills with the weapon allowed her to foil a robbery, which impressed Professor Ozpin; she was subsequently allowed to transfer early into his school, the prestigious Beacon Academy, to continue her training. To help hone her potential, Ozpin placed Ruby in a team alongside her older half-sister Yang Xiao Long, heiress Weiss Schnee and the Faunus Blake Belladonna, forming Team RWBY.
