The My Hero Academia universe is full of heart-pounding battles, emotional storylines, and unforgettable characters, but few moments stand out as much as the legendary fight between Izuku Midoriya (Deku) and Kai Chisaki (Overhaul). Taking place in Season 4, Episode 13 (“Infinite 100%”), this episode quickly became one of the most talked-about moments in anime history.
Fans were captivated by the intense animation, jaw-dropping power-ups, and deep emotional stakes that made the fight unforgettable. This wasn’t just another hero-vs-villain showdown; it was a defining point in Deku’s journey and a true showcase of the series’ brilliance.
Episode Recap (Spoiler Warning)
The episode begins with a tense atmosphere. Overhaul, leader of the Shie Hassaikai, is determined to protect his criminal empire, while Deku and Mirio “Lemillion” Togata are equally determined to rescue Eri—a little girl who has been exploited and abused for Overhaul’s experiments. The stakes couldn’t be higher.
After Mirio’s heroic efforts to save Eri in previous episodes, Deku takes center stage in this fight. With Eri in his arms, Deku pushes himself to the absolute limit. Overhaul proves himself to be a terrifying opponent with his Quirk, which allows him to disassemble and reassemble anything he touches, including his own body. He fuses with his surroundings, becoming a monstrous, god-like creature that towers over Deku.
At first, Deku struggles. Even at his strongest, using One For All at 20%, he’s no match for Overhaul’s overwhelming power. However, Eri’s Quirk, Rewind, activates uncontrollably, allowing her to reverse Deku’s injuries and keep him at peak condition. This becomes a game-changer, as Deku finally unleashes the full 100% power of One For All without destroying his body.
What follows is one of the most visually stunning and emotionally charged fights in anime: Deku, glowing with energy, soars through the air at unimaginable speeds, dodging Overhaul’s attacks and striking with devastating blows. Ultimately, he defeats Overhaul, securing Eri’s safety and cementing himself as a symbol of hope.
Why This Fight Stands Out
A. Emotional Stakes
At its core, this fight wasn’t just about strength or flashy powers; it was about hope, redemption, and heroism. Deku’s determination to save Eri resonated deeply with fans. Eri’s tragic backstory—being abused, manipulated, and treated as nothing more than a tool—added emotional weight to every moment of this battle.
Deku’s actions were not simply heroic in the traditional sense; he embodied the true spirit of a hero. He didn’t care about glory, fame, or even his own safety. His only goal was to rescue Eri and reassure her that she didn’t have to live in fear anymore. The moment Deku reaches out his hand and tells her not to be afraid is one of the most heartwarming scenes in the entire series.
This emotional depth set the fight apart from countless other anime battles. Fans weren’t just watching a hero defeat a villain; they were witnessing a young boy take on the weight of the world to save a single child.
B. Animation Quality
The animation of Episode 13 (“Infinite 100%”) deserves special recognition. Produced by Studio Bones, this episode pushed the boundaries of what anime fight scenes could look like. Every frame felt dynamic and alive, with fluid motion, incredible camera angles, and breathtaking detail.
One of the most iconic sequences is when Deku, glowing with golden energy, soars through the air while carrying Eri. The speed, force, and intensity of his movements are beautifully illustrated, creating a sense of awe that’s hard to forget.
The fight choreography is equally impressive. Overhaul’s monstrous transformations are depicted in a way that makes him both terrifying and visually stunning. The clash of Deku’s pure, unrelenting power against Overhaul’s chaotic, shape-shifting attacks created a fight scene that fans rewatched over and over again.
In addition, the music and sound effects elevated the scene even further. The soundtrack, particularly the triumphant orchestral score, perfectly matched Deku’s transformation into a true hero. This combination of visuals and sound created an emotional and cinematic experience that rivaled even the best fight scenes in anime history.
C. Deku’s Power-Up Moment
Deku’s full-power transformation is one of the highlights of the entire series. Up until this point, he had been limited by his inability to control One For All without injuring himself. His maximum power output often left him broken and unable to continue fighting. However, thanks to Eri’s Quirk, he was finally able to go all out without consequence.
Seeing Deku at 100% Full Cowling was nothing short of epic. For the first time, fans witnessed what One For All could truly do in the hands of someone determined to save others. His movements were so fast and powerful that even Overhaul, who was considered unbeatable, stood no chance.
This moment was also symbolic of Deku’s growth as a character. From a boy who started the series powerless, Deku had now become a hero capable of incredible feats. It was a glimpse into the future—what Deku would one day become when he fully masters his Quirk.
D. Overhaul’s Villainy
Kai Chisaki, known as Overhaul, is one of the most terrifying villains in My Hero Academia. His calm demeanor, obsession with “fixing” the world, and ruthless nature made him a chilling antagonist. What truly made him stand out was his Quirk, which allowed him to break down and reconstruct matter at will.
Overhaul’s abuse of Eri and his cold, emotionless approach to achieving his goals made him a character fans loved to hate. In this battle, his monstrous final form symbolized the extent of his cruelty and desperation. This wasn’t just a fight of strength; it was a battle between pure evil and pure good. Deku’s victory was not only physical but moral—it showed that compassion and bravery will always overcome cruelty.
Fan Reactions
When this episode aired, the anime community exploded with excitement. Social media platforms like Twitter, Reddit, and Instagram were flooded with clips, fan art, and reactions. The hashtag #Infinite100% trended worldwide, and fans praised Studio Bones for their incredible work.
Many considered this fight one of the best anime battles of all time, putting My Hero Academia on par with other iconic shonen series like Naruto, Dragon Ball Z, and One Piece. Some fans even ranked it as the best episode in the entire series. The emotional connection to Eri, combined with stunning visuals, made this fight a cultural milestone.
