Jotaro Kujo makes his debut onto the blog with this battle and he’s up against Luke Skywalker! Luke’s lightsaber is a great weapon and he can also use The Force to a mild extent. Luckily for Jotaro; his stand is quick enough to ensure that they will always be out of range and a counter attack would not be out of the question. Luke just won’t be able to cope with Jotaro’s speed and Luke isn’t known for his incredible feats of defense. Jotaro Kujo wins.

Tbh for once this battle can go either way.
In power alone luke beats star platinum.
Since luke has been comparable to other jedi that can move planets and blackholes.
hell luke could easily crush jotaro’s organs.
But then agian since luke is not a stand user he cant hurt or see star platinum, sure maybe sense sp but not hurt him, so his lightsaber is basically useless.
And while luke is faster in reaction time once agian, cant hurt him with a lightsaber
and bare in mind in physical strength sp beats luke.
And then also bare in mind jotaro could just stop time and give luke the kakyoin treatment by punching a whole through him.
So overall it really depends on who can end it first, either luke crushes jotaro’s heart first with the force or jotaro stops time and donut’s luke.
While luke’s way of killing jotaro is more faster technically he really does not do this to extreme measures, but then agian we dont see jotaro stopping time the first time in a fight.
So all in all this fight is a mess and both characters can pretty much one shot each other.
There really is no clear winner to this debate.
I’d definitely go with Jotaro here though because Luke usually isn’t ready for the clutch moments. He also just couldn’t really mess with Jotaro in close quarters combat
