RWBY (pronounced "ruby") is an American 3D original net animation created by Monty Oum for Rooster Teeth Productions. The first episode was released on the Rooster Teeth website on July 18, 2013, following an exclusive screening at RTX. The second volume premiered on July 4, 2014, at RTX and to the general public on July 24, 2014, followed by the third volume on October 24, 2015.
Following its announcement, the show became a viral hit, resulting in many cosplays and fan adaptations. One of these adaptations, a fan game titled RWBY: Grimm Eclipse, was later officially adopted by Rooster Teeth, and was fully released for PC on July 5, 2016.
On February 1, 2015, Oum died as the result of a coma that was caused by an allergic reaction during a medical procedure. This left the future of the series uncertain for a brief period of time until voice actor Gray Haddock announced that the series would continue, and that Volume 3 would premiere in 2015 as planned.
Volume 4 was officially announced on April 1, 2016. It is set to premiere on October 22, 2016. Volume 4 will take place 6–8 months after Volume 3, with everyone having new designs.
A spin-off of the show, titled RWBY Chibi, was also announced. Episode 1 premiered on May 7, 2016.
The story takes place in a world filled with monsters and supernatural forces named the creatures of grimm. The series focuses on four girls, each with their own unique weapon and powers, who come together as a team at Beacon Academy in a place called Vale where they are trained to battle these forces alongside other similar teams. Prior to the events of the series, mankind waged a battle of survival against the shadowy creatures of the Grimm until they discovered the power of Dust, which allowed them to fight back against the monsters. Dust is used to power magical abilities and weapons in the series.
