First of all, Dior can use a variety of abilities. In the third part, Dior has a body body double, and he has trained a large group of subordinates with different abilities. If he adapts to Da Qiao's body, he will probably regain his former vampire ability. Katz's ability is mainly focused on strengthening himself, not as many tricks as Dior.
Secondly, the stopping ability of Dior's body body double's "world" is very difficult to deal with, and Dior can use the stopping time of "world" to continuously consume Katz.
Finally, the official fan Lidio's plug-in is more powerful than Katz's. Katz's plug-in is the ability to copy body double, and Dior's plug-in is to rewrite reality.
If you want to select the strongest boss in jojo's wonderful adventure, Katz and Dior must be on the list. Katz is called the "extreme creature". He can hardly die, no matter how many injuries he has suffered, he can recover immediately. Even hot lava can't kill him.
Dior is a senior vampire. He is always young, and he can recover instantly even if his body is split in two. The first Dior has super moves such as gasification and freezing, and the third Dior wash. Although I lost the vampire's moves, I gained the "world" that body double can stop from time to time. Dior and Katz once brought great pressure to jojo's leading group, while Er Qiao and Nobutaro made great efforts to defeat the two boss.
