Mikasa was one of the most skilled Scouts in the Attack On Titan universe and a woman with abnormally high physical strength. She was fast enough to catch up with and defeat a fleeing Annie Leonhart and powerful enough to carry massive steel beams over her shoulder without being notably encumbered.
Subsequently, there are few characters from her series capable of defeating her. However, Mikasa's success in her own anime does not entail safety against the denizens of Hunter X Hunter. By matching her against a diverse roster of adversaries, we can better put the Ackerman's skills to the test.
10 COULD BEAT: Mikasa Has Dodged Bullets Like Franklin's Before
Franklin was a member of the Phantom Troupe who could shoot Nen bullets from his fingertips. They were potent enough to massacre an entire auction in a matter of seconds and were just as efficient as traditional projectiles.
However, Mikasa has proven an ability to dodge gunfire from point-blank range during her battles against Kenny Ackerman's anti-ODM squad and the Marleyan forces. Therefore, she could weave around the villain's attacks before decapitating him with her sword.
9 WOULD LOSE TO: Shizuku's Vacuum Would Inhibit Mikasa's Mobility
Shizuku's vacuum was able to emit a powerful suction that pulled everything nearby inside. Considering that Mikasa's maneuverability is limited while her ODM gear is deployed, this would make her a likely target for the vacuum.
The Scout's only reprieve would be to attempt to overwhelm her opponent with thunder spears while remaining out of reach. However, with strength comparable to Gon's (who in turn could move several ton gates with his bare hands), Shizuku would be likely to survive the attack and finish her grim task.
8 COULD BEAT: Kurapika's Emperor Time Is Only Useful Against Members Of The Phantom Troupe
Able to access all forms of Nen, Kurapika's strength is among the greatest of the series. His invisible chains are especially formidable to an adversary who cannot harness Gyo to see them (such as Mikasa).
However, he has placed a Nen condition on himself so that his tremendous gifts can only be employed against members of the Phantom Troupe. Should he attempt to engage Mikasa without his powers, she would handily manage to cut him down with thunder spears and swordsmanship alike, forgoing the need to use her Ackerman burst of strength.
7 WOULD LOSE TO: Youpi Can Take An Astounding Amount Of Abuse & Remain Unscathed
Youpi was a royal guard for Meruem who managed to contend with godspeed Killua (a Zoldyck assassin who was capable of ripping out his target's hearts instantly even in base form). He shrugged off staggering abuse with minimal effort and could transform his body into grotesque appendages to seize flying opponents (like Shoot McMahon).
Therefore, not only does Mikasa lack the firepower to destroy Youpi but getting anywhere in his vicinity would be an unspeakably perilous endeavor bound to produce disastrous results.
6 COULD BEAT: Leorio's Attacks Are Unpredictable But Most Inconsequential
Leorio had the ability to concentrate Nen into his fist and strike enemies through a portal. This would afford him a decent amount of unpredictability against Mikasa, especially since he could punch her as long as he could visually see her.
However, Mikasa's ODM gear makes it so that she'd be able to breeze past his fists before they even had a chance to emerge from their gateway. Without a weapon of his own, the doctor would be completely incapable of preventing his opponent from cutting him down.
5 WOULD LOSE TO: Gon Has Durability & Versatile Attacks
Gon was durable enough to withstand the explosions of the Bomber by concentrating his Nen around his body as a shield. Similarly, he would be able to withstand the initial impact of Mikasa's thunder spears -- or at the very least, press forward with negligible injuries.
While Mikasa's ODM gear would prove a challenge for most opponents to target, his "Paper" technique provides a superb ranged utility that would slice through her cable and bring her out of the sky. From there, he could choose between his "Scissor" or "Rock" attacks to finish her off.
4 COULD BEAT: Porcupine's Bristles Don't Protect Him From Explosions
Porcupine was a member of the Shadow Beasts whose thick bristles rendered him virtually immune to physical harm. This would prevent Mikasa from slashing through him, as her blades would be caught within his facial hairs.
However, the criminal has no such safeguards against the explosive force of a thunder spear. Should Ackerman target one of her missiles at his feet, she could engulf him in fire, capitalizing on his low durability in order to take his life.
3 WOULD LOSE TO: Hisoka's Bungee Gum Is Treacherous & Mysterious
Hisoka's Bungee Gum allowed him to catch and deflect attacks as fast as bullets, suggesting that he would be able to turn Mikasa's thunder spears back against her before they detonated. He also had superb durability, having successfully faced off against multiple adversaries who could move fast enough to leave after images of themselves (Gon being the most notable of them).
Since he could catch and disarm Mikasa with his gum just as easily, she would be without weapons and forced to contend with the villain in hand-to-hand combat -- a battle the Scout has no hope of winning.
2 COULD BEAT: Ponzu's Bees Can't Block A Thunder Spear
Ponzu was able to overwhelm her opponents with a swarm of venomous bees. This would make it extremely dangerous for Mikasa to confront her headlong even if she chose to use her Ackerman strength.
However, the hunter's minions are vulnerable to fire and would not be able to stop the explosive force of the Scout's thunder spear. Considering that Mikasa carries five of such devastating projectiles with her at any given time, she would be more than equipped to dominate her adversary.
1 WOULD LOSE TO: Netero Has Unfathomable Reflexes & An Unstoppable Nen Ability
Netero's guanyin bodhisattva was a gigantic golden statue that was fast enough to swat Meruem out of the air hundreds of times, who in turn could kill a dozen people in the blink of an eye. Combining brutal force with fantastic range, he is equipped with the means to strike down Ackerman just as easily.
Mobile enough to dodge Killua and Gon at the same time, he'd obviate Mikasa's thunder spears just as easily, thereby eliminating her last chance of success in the battle once her arsenal was depleted.
