The story in JoJo is divided between two universes; the first detailed in Weekly Shonen Jump from 1986 (2th December) to 2003, and the second primarily in seinen magazine Ultra Jump, from 2003/04 to the present.
The first begins with Part I: Phantom Blood; featuring the fraught and bloody relationship between usurper Dio Brando and hero Jonathan "JoJo" Joestar. Attrition between Jonathan's descendants (each identifiable as "JoJo") and their allies and Dio's followers characterizes a broad continuity to this series: In Part II, Jonathan's grandson Joseph combats the Pillar Men, creators of the Stone Mask which granted Dio his Vampiric powers; in Part III, Joseph's grandson Jotaro combats Dio's army of Stand users before Dio (now referred to simply as "DIO") himself; in Part IV, Joseph's son Josuke faces a host of new Stand users in his community in Morioh, Japan; in Part V, DIO's son Giorno fights for his position atop the mafia hierarchy in Italy; and in Part VI, Jotaro's daughter Jolyne battles Enrico Pucci, Dio's acolyte.
The second universe begins with Part VII: Steel Ball Run; featuring many references to events in the former series. Set in 1890, SBR focuses on the fierce competition between dual protagonists Gyro Zeppeli and Johnny Joestar and various other agents for the acquisition of an invaluable, world-defining mystical object, under the cover of the epic American Steel Ball Run race. Leaping to the present day in Part VIII: JoJolion, secret implications to this history are investigated along with the mystery of the protagonist's ultimate identity and the paranormal circumstances surrounding his adoptive hometown.

In terms of destructive feats: the verse's top tiers reach up to City Block busting to Island level environmental destruction. It's lower tiers being somewhere in the range of Below Human level to Large Building level.
Speed-wise, top tier stands can go up to Massively FTL speeds (with at least only a couple being able to reach Infinite speeds). The rest being anywhere from Below Human to around FTL or higher. Not including the stands, the characters only go up to Supersonic+ speeds, with only a couple having FTL+ reaction and combat speed.
JJBA's true strong point, however, is in their hax abilities. It has several characters capable of messing with time (three can stop it, one can loop it, another can erase it, etc.), a universal resetter which only "God" can keep up with, a user with a stand that manipulates causality and can exist even when time is erased (albeit, this is only by his stand), an ability that, when perfectly used, produce infinite damage, pierce through dimensional walls/realms plus ignore durability and space-time manipulations, and many more.
