Ruby Rose

"Ruby Rose, the leader of Team RWBY. She's here to help not only me, but also the Preschool Girls, even for their boss, Miles Callisto, and the rest of her Future Alliance comrades, not to be confused with the Preschool Girls' beloved leader, Ruby Ramirez."

--Su Ji-Hoon, The Rise of Team RWBY

Ruby Rose is a former student of Beacon Academy and the main protagonist of RWBY. Ruby's weapon of choice is her High-Caliber Sniper-Scythe known as Crescent Rose.

She first appeared in the "Red" Trailer visiting the grave of her deceased mother, Summer Rose. After an invitation from Headmaster Ozpin following an altercation with Roman Torchwick, Ruby attends Beacon Academy in order to become a Huntress. During her time at Beacon, she is the leader of Team RWBY, consisting of Weiss Schnee, Blake Belladonna and her half-sister, Yang Xiao Long. However, following the Fall of Beacon, Ruby travels to Haven as a member of Team RNJR until Team RWBY's reunion at Haven Academy.

In When the Cold Breeze Blows Away, she helps the Preschool Girls (and later including the Sonic Alliance), including Su Ji-Hoon, into their adventure throughout World War III.
