Parallel World

The Steel Ball Run Universe (or SBR Universe for short) is the new alternate world created at the end of Stone Ocean where the next parts of JoJo's Bizarre Adventure will take place in a different continuity from the original timeline the first six parts took place in. This universe gets its name from the seventh part of the series to first take place in this new world, Steel Ball Run.

Creation
Stairway to Heaven (Made in Heaven)

Following Enrico Pucci's death the world experienced another Big Bang caused by the power of his Stand Stairway to Heaven (Made in Heaven)'s ability to create new dimensions. In this new world Jolyne was brought back to life after dying fighting Pucci along with alternate versions of her friends the only expections being F.F and Emporio Alnino who retained his memory of the orginal world and goes with the new versions of his friends so Irene's fiancé can meet with her father to approve their marrage.

Steel Ball Run
Steel Ball Run, the seventh part of the series would show the other major changes to the Joestar Family by going back to the late 1800's where the SBR version of Jonathan Joestar would be shown to be a completely different person to his orginal counter-part as he tries to learn how to use the Spin used by his future teacher and close friend Gyro Zepelli as he hopes it could give him his mobility back after being paralyzed from the waist down while also competing in the Steel Ball Run..

JoJolion
Jojolion, the eighth part of the series is set in the year 2011 and shows another SBR counter-part of a past JoJo, this time being Josuke Higashikata as he tries to find clues on his identity as he is suffereing from amnesia. Along the way he finds ties to himself and another SBR version of a past JoJo though how they are tied is unknown apart from the fact they have both been fused together causing the creation of a new Stand for Josuke.
