JoJo’s “Fight Meh” Era is iconic. He went to the center of TEEGARDEN-B, where all the heroes/villains were. And he fought all of them one by one as one of his best ways of training in TDW in general.
Also the jump in powerlevels is due to the time skip between GREKISITE JoJo and Fight Meh JoJo. (Around 3-5 years.)
