Time Stop is restricted because this isn't Star Platinum: The World, right? I mean, it's a matter of key, not or overall restriction.
I don't think Raiden would feel threatened by Jotaro from the get go unless he could sense Star Platinum
Raiden isn't one who underestimates the opponent, tho, and has dealt with esotic fighting styles before, so he isn't likely to underestimate his opponent.
With ESP, he can sense energy signatures, and his Enhanced Senses allow him to feel the presence of people in a realm, tho I don't know if it works on intangible beings.
He may feel the presence of Star Platinum, as stands are made of fighting spirit, which may count as energy, but Raiden's ESP don't seem that precise on that regard.
Also if Raiden did run and try to outrange Jotaro. Jotaro has his own projectiles of his own, aka punching the ground and throwing the rocks he gets from destroying some part of the ground. At maximum it could go so far as 400 meters (As shown with him throwing Iggy) He could probably do precise projectile throws thanks to his extreme precision.
Raiden can fly, counter with his lightinings (attacks and forcefields), and most of all, teleport around, which he does a lot, and also he has good acrobatics.
Star Platinum is very precise (tho I don't remember feats), so he shouldn't totally be outmatched, but rocks aren't the most efficient projectiles either.
Most people in the MK verse also use projectiles, meaning he's used and dealing with them.
If the fight goes into close range, Raiden might be in trouble as he has no way to determine when,how and where Star Platinum would hit him. Star Platinum can land many blows and Raiden has no chance of blocking it if he does not know where to block in the first place, Star Platinum might even have the speed advantage just a bit if Jotaro was really close to SP. His Lifting Strength is also there to help Jotaro restrain Raiden, ragdoll him around and possibly punch his face for free.
Raiden has quite a lot of fighting experience (both for sheer age and for number and quality of opponents) and is a master martial artist, even if he wasn't able to sense SP at all, he wouldn't be defenseless against someone who basically punches your upper body a lot, and would quickly understand that the one who fights isn't Jotaro, and also may notice SP range limit.
Restraining Raiden is possible, yes, but he can also teleport and release lightinings or flashes of light to at least affect Jotaro in some way.
Raiden should be able to outrange via lightning attacks and flight. He has demonstrated willingness to use said moves when threatened and Jotaro doesn't have time stop. This is basically Jotaro vs The Sun all over again. I think you actually should give him time stop
Correct, Raiden is prone at frying the opponents with streams of lighting (
1,
2,
3,
4).
For Jotaro to deal with Electricity, if Jotaro can block the electricity Raiden sends out with Star Platinum, he wouldn't get damaged which is a great thing for Jotaro so he has a defensive shield. He can probably use Star Platinum like just right in front of him as some sort of pseudo armor so electricity just won't get pass star platinum and boom Jotaro dead. In terms of Defense, Jotaro is solid thanks to Star Platinum but if Raiden can get pass Star Platinum aka Jotaro's shield, Jotaro is essentially toast.
I honestly don't know how that would work, since Stands can interact with and stop physical things (like bullets), the same may be possible for lightnings.
But yet again, it wouldn't take much for Raiden to understand that there's an invisible thing that acts as a shield and an attacker, and he may try to get right into Jotaro with teleportation, and from close distance he has many projectiles, bombs, explosions and more that travel through the air and the ground or two different points (like lightnings traveling between two orbs or him and his staff) or summon them
directly over Jotaro.
The stats amp bit of the previous message is totally valid.
Overall, I'd say Raiden has more chances of winning, but I may change my vote.
