So i just finished reading stardust crusaders and I have to ask… Then ending, the way it ends... Is there a real reason why the final fight ends the way it does or is this another case of "because Araki"?
! Do you mean the timestop or the final hit?
! The timestop was because… Remember at the beginning, when Joseph revealed that the Joestar family were developing stands because Dio had developed a stand within Jonathan Joestar's body? This was the reason why Joseph and Dio both used Hermit Purple. Then, during the final fight, we saw that the World's battle style was extremely similar to Star Platinum's. In the end, they were basically the same stand, and it's also the reason why Jotaro was able to resist the timestop throughout the battle, before actually using it.
