Jojo's Oscillated Odyssey is a fan made universe within the Jojo's Bizarre Adventure Continuity. It's identical, up until the events of Battle Tendency. During Battle Tendency, A New Bloodline is brought forth. And with the addition of this new bloodline, there are new people. And due to the addition of these new people, Anomalies begin to occur in the timeline, splitting it from the first. For example, having Caesar Zeppeli Survive in Part 2, to go and guide the others in part 3. Or, having Dio nearly win against the stardust crusaders. These Anomalies begin to change all of time.
Everything Found within this universe can be found... H E R E !
