Lovely warrior
You forgot "Jotaro is stuck and can't get close to the enemy? He suddenly has a move that makes him ****ing reach said enemy". Tbf Araki forgot about Star Finger tooJotaro is a particularly egregious example, because Star Platinum's abilities are literally just "whatever the plot needs it to have".
Need to examine a photo to find out where DIO is? Oh, Star Platinum has eyes that can zoom into a fly in the darkness of the background.
Stuck in the mouth of a Stand whose teeth have been basically unbreakable up until this point? Star Platinum can suddenly punch hard enough to break them.
DIO's Stand is too powerful, and his time-stopping skills can't be stopped? Star Platinum can stop time too.
(this is a non-canon example but still counts) DIO has ascended to literal godhood, and now his stand can literally rewrite reality as he sees fit? Guess what, all of a sudden Star Platinum can do that too, even though DIO had to go through an unbelievably complicated ritual that involved killing dozens of Joestars across multiple timelines to achieve his power.
