Naturally, fans love to ponder the ultimate "what if" scenarios: when two titans from different universes clash, who emerges victorious? Today, we dive deep into one such electrifying matchup: the stoic Devil Hunter Aki Hayakawa from Chainsaw Man squaring off against the lightning-fast Demon Slayer Zenitsu Agatsuma from Demon Slayer.
Both characters are beloved for their unique strengths, personal struggles, and incredible moments of power. Zenitsu, the cowardly swordsman who becomes a whirlwind of thunder in his sleep, and Aki, the pragmatic devil hunter burdened by tragic contracts, present a fascinating contrast in fighting styles and power sources. This super pillar hub will dissect their abilities, examine their combat prowess, and ultimately attempt to crown a victor in this hypothetical, high-stakes battle.
Let's break down everything you need to know to understand this epic crossover confrontation.
Unpacking Zenitsu Agatsuma's Electrifying Arsenal
Zenitsu Agatsuma, despite his often comical cowardice, harbors immense potential and terrifying speed. He is a master of Thunder Breathing, a specialized combat style that focuses on blinding speed and singular, devastating strikes. While he initially only mastered the First Form, "Thunderclap and Flash," his proficiency with it allows him to move at superhuman velocities, striking multiple times in an instant.
His abilities are amplified significantly when he falls unconscious or is pushed to his absolute limit, transforming him into a focused, unyielding warrior whose movements are almost impossible to track. Zenitsu's "Godspeed" technique pushes his reflexes and coordination beyond normal limits, allowing him to accelerate even further. He even develops a Sixth Form of Thunder Breathing, showcasing his profound growth. For a more detailed look into his combat style, explore the .
Zenitsu's raw talent, even if often hindered by his personality, is undeniable. He's proven capable of defeating Lower Rank Demons single-handedly, a feat that speaks volumes about his individual power within the Demon Slayer universe.

Aki Hayakawa: A Devil Hunter Forged by Contracts and Tragedy
Aki Hayakawa is a Public Safety Devil Hunter whose strength isn't just his own, but also stems from his perilous contracts with various devils. As a human, Aki is a formidable combatant, exhibiting enhanced physical characteristics, exceptional mastery of swordsmanship, martial arts, and stealth tactics. His signature weapon is a katana, wielded with deadly precision.
His contracts grant him unique, often terrifying, abilities:
- Fox Devil Contract: Allows him to summon parts of the Fox Devil's body, typically its massive head, to devour targets.
- Curse Devil Contract: A particularly brutal power, this contract provides him with a nail-shaped sword. Stabbing an enemy three times with it invokes the Curse Devil, resulting in instant death for the target—at the cost of a significant portion of Aki's lifespan.
- Future Devil Contract: Grants Aki the ability of limited precognition, allowing him to see a few seconds into the future. This invaluable foresight comes at the chilling price of his right eye.
Aki's journey, however, takes a darker turn when he becomes the Gun Fiend, possessed by 20% of the Gun Devil. In this form, his physiology transforms dramatically; his head and arms become powerful firearms, capable of unleashing devastating explosions. While his destructive power skyrockets to a multi-city block level with supersonic+ speed, his mind regresses to a childlike state, seeing mass destruction as a mere game.

The Ultimate Showdown: Comparing Their Core Attributes
Now that we've established their individual strengths, let's put Aki and Zenitsu head-to-head across critical combat attributes.
Speed and Agility: A Lightning Flash Versus Supersonic Strikes
Both Zenitsu and Aki are incredibly fast, but their speeds manifest differently. Zenitsu's "Godspeed" allows him to perform bursts of acceleration that appear almost instantaneous, capable of closing distances and striking before an enemy can react. His movements are precise and focused. Aki, especially as the Gun Fiend, operates at supersonic+ speeds, translating into rapid-fire attacks and quick evasive maneuvers across larger areas. As a human, his combat speed is also formidable, augmented by the Future Devil's precognition.
When considering raw speed and reaction time, a true contest would require a meticulous frame-by-frame analysis. Our dedicated guide does just that: .
Offensive Power: Precision Strikes vs. Explosive Force
Zenitsu's offense is about focused, concentrated power delivered through his sword. His Thunderclap and Flash, especially the Six-Fold or Eight-Fold variations, are designed to decapitate demons with surgical precision and immense force. He can generate enough force to leave craters, but his attacks are localized.
Aki, as a human, offers more versatility with his Fox Devil summons and the guaranteed lethality of the Curse Devil (if he can land three hits). As the Gun Fiend, his offensive power scales dramatically. He becomes a living weapon, capable of unleashing widespread explosive devastation that can decimate entire sections of buildings. This destructive output far exceeds anything Zenitsu has demonstrated.
Defensive Capabilities and Durability
Zenitsu's primary defense is his unparalleled speed and agility, allowing him to evade attacks. While resilient for a human, he doesn't possess any inherent regeneration or durability beyond normal human limits (albeit enhanced by his breathing techniques).
Aki, as a human, relies on his combat skills and Future Devil's foresight to anticipate and dodge attacks. His durability is enhanced but still human. As the Gun Fiend, however, he gains the general physiology of a Fiend, meaning enhanced resilience and potentially some form of regeneration, making him far tougher to put down.
Combat Intelligence and Strategic Acumen
This is where the distinction becomes particularly interesting. Zenitsu, when conscious, is often paralyzed by fear and struggles with strategic thinking. However, in his unconscious state, his instincts take over, transforming him into a ruthless, highly efficient combatant who exploits openings with deadly precision.
Human Aki is a seasoned Devil Hunter, known for his tactical mind and pragmatic approach. He understands his contracts, how to best utilize them, and makes calculated decisions even under extreme pressure. He’s intelligent, resourceful, and always thinking several steps ahead. However, as the Gun Fiend, his tactical mind is completely gone, replaced by a destructive, childlike abandon. This stark contrast plays a significant role in a potential battle.

The Broader Context: Demon Slayer vs. Chainsaw Man Power Scaling
It's also important to acknowledge the inherent differences in the power scaling between the Demon Slayer and Chainsaw Man universes. Demon Slayer operates on a scale where even top-tier demons and hashira are generally city-block to building level, with very few exceptions like Muzan or Yoriichi reaching higher. Chainsaw Man, especially with higher-tier devils and fiends, can reach multi-city block to potentially city-level destructive power. This fundamental difference in their respective universes' power ceilings impacts how we view their capabilities head-to-head. Our guide on offers a detailed analysis of these differences.
The Verdict: Who Wins This Epic Crossover Battle?
Considering all aspects, a direct confrontation between Aki Hayakawa and Zenitsu Agatsuma likely leans heavily in Aki's favor, particularly if he transforms into the Gun Fiend.
- As Human Aki vs. Zenitsu: This would be a much closer fight. Zenitsu's unconscious speed might overwhelm Aki initially, but Aki's Future Devil precognition and the devastating one-hit-kill potential of the Curse Devil (if landed) could be decisive. Aki's tactical mind would also be a major asset. Zenitsu would need to end the fight quickly, before Aki could exploit an opening or set up a Curse attack.
- As Gun Fiend Aki vs. Zenitsu: This scenario heavily favors the Gun Fiend. The sheer destructive power, multi-city block level strength, supersonic+ speed, and fiend durability would likely be too much for Zenitsu to overcome. While Zenitsu's speed is extraordinary, the widespread explosive attacks of the Gun Fiend would make evasion incredibly difficult, and a single direct hit would likely be fatal. Zenitsu's sword, designed to kill demons, might not be as effective against a devil-possessed entity like a fiend, especially one with such immense raw power.
While Zenitsu is undoubtedly a powerful demon slayer, the destructive potential and durability of the Gun Fiend operate on a different scale entirely. It would be a fierce fight, but Gun Fiend Aki's overwhelming power and endurance would likely secure the win.
