Rohan Kishibe's Stand, "Heaven's Door," can rewrite any facet of his opponent's personality, and a single glance of his manga forces them into submission. Such a profoundly useful ability renders him one of the most powerful characters not only in Diamond Is Unbreakable though in the entirety of the JoJo's Bizarre Adventure universe.
Despite his profound strength, certain adversaries can use their abilities to overcome him. By analyzing these foes, fans can understand the restrictions behind Kishibe's nearly godlike power and what it would take for Heaven's Door to be defeated. Here are 5 Stand users Rohan can beat and 5 others he cannot.
10 Could Beat - Sale
Sale's "Kraft Work" Stand can absorb his attackers' kinetic energy, rendering wounds that should be serious against normal adversaries superficial to him. He was able to withstand Mista's bullets, only failing after being shot in the same place twice.
Since Kraft Work is more inclined to defend against physical attacks than visual ones, it would give Sale the overconfidence to spell his defeat. He would allow Heaven's Door to come uncomfortably close to him, only realizing his mistake after it was too late to amend it.
9 Would Lose - N'Doul
The two primary tools at Rohan's disposal are his visual manga and Heaven's Door's direct attacks. Since N'Doul's Stand can disappear into the floor at a moment's notice and work from long-range, neither of these options would be effective against him.
Further, even if Rohan could track him down, presenting his manga would accomplish little because N'Doul is blind and, therefore, could not see it even if he wanted to. Seconds later, Kishibe would be ripped to shreds by his watery Stand.
8 Could Beat - Steely Dan
Steely Dan's offense relies more on psychological warfare than direct physical brawn. Once his Stand infiltrates his opponent's mind, the damage he sustains is magnified against his adversaries.
However, this leaves his corporeal body vulnerable. Should Heaven's Door lunge for him, open his face, and inscribe "Dan's Stand cannot harm Rohan," he would have no means of defeating the manga artist since his only viable tool has become moot. Ultimately, an absence of striking power is responsible for the defeat of the mind meddling menace.
7 Would Lose - Shigechi
There are several reasons that Shigechi would defeat Rohan, the most pressing being the nature of his Stands. With over five hundred tiny minions at his disposal, the damage taken by his "Harvests" is not reflected in his own body.
Further, they act with complete autonomy, as seen through how one of them could give Josuke Yoshikage Kira's button even after their user had been slain. Consequently, should Rohan somehow have the fortune of paralyzing Shigechi, he would still be ripped to shreds by hundreds of tiny, razor-sharp beaks.
6 Could Beat - Yukako
Yukako's Stand allows her to manipulate her hair, turning into a medium-ranged deadly weapon. Planting a single strand of her own locks on the head of any foe would allow the woman to control their opponent from a distance, putting them at her mercy.
However, she has no means of defending against Heaven's Door, nor is she capable of attacking Kishibe without looking at him. These two considerations would make it impossible for her to defeat the manga artist, especially since she can't kill him in a single attack, as necessary when fighting one of his calibers.
5 Would Lose - Narancia
Narancia's "Little Bomber" Stand allows him to control a plane capable of shooting bullets. He can maneuver it from a fair distance, giving him a considerable advantage over Rohan if he can find him before the manga artist does.
Moreover, his Stand allows him to track the heat signatures of his opponents, and as a result, he does not need to look at them directly. This would prevent Kishibe's usual tactic of disorienting his opponent through visual treachery meaningless, as the aspiring mafioso would never need to make eye contact throughout the whole battle.
4 Could Beat - Keicho
Keicho's "Worse Company" is an army of tiny soldiers able to unleash an equally minuscule series of barrages. Though it may prove a daunting obstacle against Josuke, it compels Nijimura to physically target Rohan for its success, which entails he'd have to look at him.
Moreover, Keicho's Stand would not be able to physically restrain Heaven's Door from touching him, making him unable to staunch Kishibe's impending attack. Vulnerable to both of Rohan's tools, Okuyasu's older brother poses little threat due to his disappointing defense.
3 Would Lose - Giorno (Golden Requiem)
A predominantly straightforward fighter, Giorno would fall prey to Rohan because of his dependency on his vision. However, when his Stand has evolved to "Golden Requiem," even the unrestrained might of Heaven's Door is unable to thwart him.
In this augmented state, Giorno can reset anything to the property of zero. This entails that whatever Rohan has written on the mafioso's face would expediently be reversed. Since Heaven's Door lacks physical striking power to accommodate its special ability, it reasons that it could not withstand Requiem's unabated fury in an even fight.
2 Could Beat - DIO
DIO's Stand, "the World," is capable of freezing time for five seconds (and even longer in his enhanced stage). He is physically strong enough to kill anyone he touches in a single targeted punch, as seen through how he dispatched Kakyoin.
However, the vampire is not inclined to use his Stand at the beginning of a fight, which would be his downfall. Since he is unaware of the properties behind Rohan's Stand, the manga artist would present his work to his undead opponent. Since DIO's ego would compel to look at it (if nothing else, for an opportunity to mock his adversary), he would fall under Kishibe's spell shortly thereafter.
1 Would Lose - D'arby The Gambler
An inescapable facet of Rohan's personality is that he has a massive ego. He is unable to turn down a challenge, especially when it comes to one of wits. This would work in D'arby's favor since he is expedient in such competitions.
Rohan overlooked Josuke's cheating through his modified dice. It follows that similar deceptions would be possible in a ruse the gambler arranges against him. After Kishibe had lost his nerve and the battle, D'arby would use his "Osiris" Stand to reap his soul and add it to his growing collection.
