Eren Yeager (Attack on Titan) vs Jotaro Kujo (JoJo)

R1: Battle of Shiganshina District Eren vs StarDust Crusaders Jotaro (Jotaro can't stop time). No prep, both don't know anything about each other.

R2: Battle of Shiganshina District Eren vs StarDust Crusaders Jotaro (Jotaro can stop time for 5 seconds). No prep, both don't know anything about each other.

R3: Founder Titan Eren vs StarDust Crusaders Jotaro (Jotaro can stop time for 5 seconds). Jotaro knows everything about Eren's abilities and how to defeat him, he has 3 days to prepare.

Idk Jotaro's feats, but Eren has 10k+ ton strength

@superduperbumpe:

On the JoJo Wikia, one dude claims that Star Platinum has a 475 billion newton impact force, but this is based on the assumption that his impact speed is faster than the speed of lightning (but I don't remember if there is any evidence that he really so fast).

However, Star Platinum is known for certain to be able to catch bullets with its fingers. So it seems that he is at least as good as Eren in terms of strength.

Star Platinum has punched through teeth that were supposed to be as hard as diamonds, so if we take that at face value, he could just destroy every offending limb/person that gets near him

Any version of Eren wins easily. Slowtaro just won't have the stamina to keep it up against Eren from round 1 and 2 and won't be able to defend himself from shockwaves and boulders since they might come from all sides.
Founder Eren just lolstomps.

what about pure titan 10 year old eren

@nozak: Touche. Slowtaro does beat that version of Eren quite easily, although I imagine he will feel disturbed if he realizes he's killing a little kid.

@ppsc98: Considering, as Rac95 said above, Star Platinum easy broke giant teeth, and Jotaro himself survived and continued the fight after the road roller fell on him, everything is not so clear-cut here.

@h3po4: It is clear cut. Jotaro won't be figuring out Eren's weakness any time soon and can't defend his human body against shockwaves coming from the ground or against any boulder thrown by Eren, since star plantinum won't be able to block all the debris.

@ppsc98:

Well, about the fact that he won't be able to block them all, I still doubt it, given everything that has been shown.

But your argument that Jotaro will spend a very long time before he figured out the weakness of the titans is really strong. This really increases Eren's chances of winning many times over.

@h3po4: Star Platinum couldn't even stop a couple dozen subsonic knives from hitting Jotaro, what makes you think it will stop large building level shockwaves coming from the ground? it can't cover all of Jotaro.
And thanks for the compliment fren. Happy New Year :)

Eren beats and eats

Jotaro is way faster and if normal humans with swords can kill a titan Jotaro punches him to death in all rounds.
