Legend Of The Remnant Saiyans

Back when Freeza decided to exterminate the saiyans and planet vegeta, another pair of Saiyans survived. How would remnant be different if 2 Saiyan siblings were sent off world at the time of Bardock's revolt against the tyrant and somehow ended up in the world of Rwby with their parents? Would certain events be different or.. would they stay the same? This is the story of how saiyans can literally change the fates of an entirely different reality and the consequences that come with interdimensional beings. DBS Broly like OC x Ruby, OC x Yang/Weiss.
