Rain-Bow grew up in the same village as the Fire Skylander Flameslinger. Before Flameslinger became a Skylander he defended his village and Rain-Bow fought beside him. She was unable to use a bow so instead she used a Crossbow. Later when Flameslinger became a Skylander she continued to defend the village and was given the Rainbow Crossbows for saving the Royal family of the Thunder Giants. Later she heard that Flameslinger had been captured by Kaos and she quickly came and freed Flameslinger and together escaped Kaos's Kastle. Then Flameslinger convinced her to become a Skylander and now fights evil all over Skylands!
