Warning! Spoilers for My Hero Academia: Vigilantes chapter 107 ahead!
My Hero Academia: Vigilantes‘ protagonist Koichi takes a page from Dragon Ball Super and pulls off a new technique reminiscent of Goku’s Ultra Instinct. He displays this new power as the major face-off between him and his nemesis Number Six comes to a head in chapter 107 of the manga.
An artificial being with some unclear ties to My Hero Academia‘s big villain All for One, the prototype nomu Number Six has a wide variety of powers at his disposal, making him an exceptionally dangerous foe. His most dangerous power is the one known as Overclock, which allows Number Six’s brain to operate at super-speeds, causing him to perceive time slower and react quickly to any move an opponent might make. Six also has a grudge against Koichi, and is eager to see this fight go to the death.
Koichi’s entire strategy for the fight has been to keep his distance and draw Six away from the hospital, where the formerly mind-controlled Pop Step is recovering. Koichi was supposed to summon All Might, but it doesn’t seem that he has. Six has been using Overclock to try to predict Koichi’s moves and land a fatal blow, but is repeatedly unable to. It shouldn’t be possible for Koichi to move faster than Overclock allows him to think, so what’s happening?
As it turns out, Koichi’s body is instantly reacting to Six’s attacks, without his brain actually being involved in the process at all. He’s essentially dodging a speedster using reflex alone, and retaliating with his own quirk immediately. This description almost exactly matches up with how Dragon Ball Super presents Goku’s final upgrade: Ultra Instinct. While Ultra Instinct is portrayed as an ability that even the gods of Dragon Ball have difficulty mastering, Koichi, a fairly ordinary guy without proper training, has started using this technique without even realizing it.
With the versatility he’s been able to find in his quirk, from leaping massive distances like All Might to firing projectiles and creating force fields, this kind of reflexive reading of his opponent’s moves has given Koichi a nearly impenetrable defense, even for Six’s wide array of abilities. A voice in Six’s head that resembles the original owner of the Overclock quirk warns him that this may make Koichi the one impossible opponent. The narcissistic Six can’t bear the thought and escalates by transforming into a monstrous new form. For a poetic twist to the conflict, it also happens that the original owner of Overclock was Koichi’s former mentor, the now quirkless vigilante known as Knuckleduster. It’s likely that Koichi picked up the technique from fighting alongside Knuckleduster, whose years of experience with Overclock left him with some better-than-average reflexes. In a way, Koichi is turning that very same quirk against his opponent.
Regardless of whether this power reminiscent of Goku’s Ultra Instinct technique in Dragon Ball Super is something that’s unique to Koichi or one that other characters in My Hero Academia: Vigilantes could learn, Koichi has once again proven that the average person in this world is far stronger than they know.
