About Dio match and jojo upgrade, im going to say all matches that should be removed.
Notable Victories section
Giorno Giovanna (DIO time stop and one-shot the fodder)
Diavolo (
JoJo's Bizarre Adventure)
Diavolo's Profile (this could be removed years ago, Diavolo can't do nothing aka DIO time stop and one-shot the fodder 2)
Straizo (same of diavolo, also it's kinda outadted, btw DIO pose and one-shot the fodder 3)
Dettlaff van der Eretein (massively AP stomps, DIO time stop and one-shot the fodder 4)
Notable loses section
Kars (pretty sure kars stomps, like, even in canon)
Rudol von Stroheim (why this matches got even added? Stroheim is already above santana which is above Dio, and in this case, Dio was from part 1. stroheim stomps)
Iron Man (Pretty outdated, i don't know about this one, i belive should be remaded)
Okuyasu Nijimura (Okuyasu is an idiot, Dio is more inteligent, Dio also AP stomps)
Jotaro Kujo (eh, i doubt that, Jotaro is weaker, this should probably be done again, since the result wouldn't be a stomp but not really a win for Jotaro)
Shinobu Oshino (So apparently this is done by a sword. Dio have many haxes and stuff, you know, DIO pose and one-shot the fodder 5)
Inconclusive section
Gwenpool (Gwenpool isn't that hard to counter, not even know why is inconclusive)
