Manga/Anime Differences

 * The anime started with Speedwagon's second time entering the hospital. The first time was not shown.
 * In the manga, Dio was stabbed by Jack the Ripper multiple times before he decided to join him. In the anime, Dio used some type of mind control and Jack was instantly subdued.
 * The flashback explanation of how Dio escaped the mansion alive was not in the anime.
 * The battle between Jonathan and Wang Chan was not shown in the anime.
 * During the battle with Jack the Ripper, Jack launches a bunch of knives out of his body. In the manga, Jonathan and Speedwagon hide behind a rock. Speedwagon is also cut in the shoudler by one of the knives. In the anime, they do not hide, and Speedwagon is not harmed.
 * In the manga Zeppeli told a history about a fisherman who cut his own leg to attack a shark and kill it. In the anime he never told this history.
