User blog comment:Bruhboy222/in your opinion, what would happen if DIO actually beat jotaro???/@comment-38972739-20200726130220

well, everything that you said above would be true.

dio would absorb jotaro's blood and get get the world over heaven, then become the the most powerful being on earth (sorry kars).

polnareff would probably die from blood loss after trying to save jotaro and if he somehow survives, i doubt that polnareff would win against dio.

if polnareff looks into stand arrows, gets the requiem arrows and manages to control chariot requiem, maybe he would have a chance against dio, but at that point i think he would already have the world over heaven, which turns him into literal god.

part 4 would not happen, because i think joseph got with tomoko after the dio fight, so no josuke, and hand fetish man would live a quiet life (chew). actually scratch that because dio didn't die, so okuyasu and keicho's dad prob won't become a zombie (?), that leaves keicho no reason to looks for stand arrows and make stand users. kira would still have his stand tho because his yoshihiro (his dad) personally pierced him with one, so killer queen fans rejoice. (yay!)

part 5 would probably not happen, because dio's body was jonathan's, and since he would've already erased the joestars from history, giorno would not be born, trish would be dead, diavolo does evil mafia boss things.

BUT if giorno was born, and everything else happened, polnareff would probably not be able to help them because of his solo research with stand/requiem arrows. so giorno and gang would probably not be able to kill diavolo.

part 6 would not happen, jolyne not born, prison stuff happens, pucci resets universe.not sure about that last one because dio is alive but eh.

for part 7 and 8, not sure.

so yeah, that's my analysis. hope you take some time to read this and have a good one.
