Gravity Falls and Gravity Rush Crossovers
Darkness Rush Falls by TheFallerGeek
It has been 3 years since Mabel and Dipper left Gravity Falls. When they come back, it was not how it turned out to be. It was full of darkness so a clever girl named Kat and her cat help them to fight against all evil especially against Raven and Bill Cipher. Rated T for some swearing and violence
