When it comes to preparing for the impossible, no one in the DC Universe does it better than Batman. As a 25-year-old comic book blogger with over five years of experience dissecting superhero lore, I’ve always admired the strategic brilliance of Bruce Wayne. His encounters with godlike beings—especially Kryptonians like Superman and Supergirl—are a true masterclass in survival without superpowers. Most fans know Batman always keeps Kryptonite nearby, but few realize he also has a lesser-known, gadget-free trick up his sleeve: Klurkor, a Kryptonian martial art.
Let’s break down how Batman uses Klurkor to outsmart and overpower even the most fearsome Kryptonians, especially in his iconic clash with Supergirl. This blog post will explore Klurkor’s origin, its relevance in DC canon, and how Batman turns this alien fighting technique into one of his greatest advantages—without ever relying on gadgets or Kryptonite.
What Is Klurkor?
Klurkor is a Kryptonian martial art designed specifically for hand-to-hand combat among Kryptonians. Unlike Earth-based martial arts, which rely heavily on strength, balance, and speed, Klurkor is adapted to combat beings with superhuman abilities. Think of it as Kryptonian jiu-jitsu—a fighting form engineered to deal with ultra-strength, invulnerability, and hyperspeed.
In Batman/Superman: World’s Finest #22 by Mark Waid and Dan Mora, we see this technique in full effect. Supergirl, under mind control, tries to overpower Batman. Despite being outclassed in every physical category, Batman subdues her using Klurkor techniques. This shows that Bruce doesn’t just train for strength—he trains for strategy, speed, and technique tailored to his enemies.
Batman doesn’t just know Klurkor—he masters its essence, which is using an opponent’s strength against them, perfect for fighting Kryptonians.
Batman’s Fight with Supergirl: A Pure Skill Battle
The most notable demonstration of Klurkor in action is Batman’s confrontation with Supergirl. She’s brainwashed and attacking him with full Kryptonian force. Any other human would be obliterated in seconds. But not Batman. He doesn’t use any gadgets, no Kryptonite grenades, no power armor—just pure skill.
He teases Supergirl, saying he hasn’t learned Klurkor—before flooring her in a surprise move. The fact that she admits to only being trained at the “first level” of Klurkor shows the hierarchy and depth of the martial art—and how much more Bruce has mastered.
This moment is peak Batman. No powers, no tech—just training and intellect. This also elevates Batman beyond the “rich guy with gadgets” label and cements him as a true martial arts genius.
Why Did Batman Learn Klurkor?
Batman prepares for everything. He has contingency plans for every member of the Justice League, including Superman, Wonder Woman, Green Lantern, and yes, even Supergirl. Kryptonians may be allies today, but Bruce knows the tides can shift quickly in the superhero world—mind control, alien possession, corrupted timelines—the threats are endless.
Klurkor gives Batman a tactical advantage if he’s ever caught off guard, especially when he’s without his suit or arsenal. He can survive an encounter, or even win, purely by relying on knowledge and muscle memory.
And it’s not just about defeating enemies—it’s about understanding them. By learning Klurkor, Bruce demonstrates respect for Kryptonian culture and acknowledges that brute force isn’t always the answer.
Klurkor’s Canon History in DC Comics
Although Klurkor isn’t as frequently featured as Batarangs or Batmobiles, it holds a solid place in DC Comics canon.
Supergirl #40: Kara uses Klurkor when she loses her powers temporarily to Gold Kryptonite.
Lois Lane in Kandor: During her time in the bottled city of Kandor, Lois Lane also learns Klurkor to protect herself against Kryptonians.
Batman’s Amazon Training: In alternate timelines, Bruce trains alongside the Amazons and even Kryptonians, using Klurkor as part of his hand-to-hand arsenal.
So far, only three Earth-born characters are known to have learned Klurkor: Batman, Lois Lane, and a version of Supergirl who trained with Bruce and the Amazons. That rarity gives the technique even more mystique and weight in DC lore.
Why Is Klurkor So Effective?
Here’s a breakdown of why Klurkor is such an effective martial art for Batman:
1. Designed to Neutralize Kryptonians
This is the biggest advantage. It’s made for Kryptonians to fight each other, meaning it works against beings with strength, speed, and heat vision. Bruce uses that to great effect.
2. Doesn’t Rely on Equipment
No gadgets, no Kryptonite, no armor. Just pure muscle memory and movement. That makes it usable in any scenario, even if Batman is captured or disarmed.
3. Psychological Warfare
Imagine being a Kryptonian who thinks you’re invincible—and suddenly a human flips you to the ground. The psychological impact of that alone gives Batman an edge in any fight.
4. Unpredictability
Most opponents expect Batman to fight using his Earth-based martial arts. Klurkor adds an alien element to his technique, throwing even the smartest enemies off balance.
The Larger Implications of Batman Learning Klurkor
This small detail opens up huge narrative possibilities in the DC Universe:
- Could Batman teach Klurkor to other non-Kryptonian heroes like Nightwing or Batgirl?
- Will future conflicts with Rogue Kryptonians see the return of Klurkor as a necessity?
- Could Klurkor evolve into a global self-defense system against extraterrestrial threats?
It also humanizes Kryptonian culture—showing they have arts, rituals, and disciplines beyond just powers and flying capes.

Why This Matters for Fans and Storytelling
For us fans, Klurkor is exciting because it challenges the norms. It shows us that raw power isn’t everything—and that dedication, training, and discipline can overcome even the mightiest foes.
It also makes Batman relatable. He doesn’t have alien DNA or Amazon blood. He’s just a man who pushes himself beyond human limits. And that’s why readers love him. Klurkor is just another example of how far Bruce is willing to go to be ready.
This is the kind of storytelling DC should explore more deeply—where physical power isn’t always the trump card. Where knowledge, precision, and courage make the real difference.
Final Thoughts: The Dark Knight Doesn’t Need Powers to Win
Batman has always been the poster boy for preparation beats power. His mastery of Klurkor isn’t just a cool plot twist—it’s a testament to his character. When the chips are down and the powers are gone, it’s Bruce Wayne’s training, mindset, and resilience that save the day.
As a 25-year-old fan who has followed superhero comics and animated series since childhood, I believe Batman’s use of Klurkor is one of the most underrated moments in modern DC storytelling. It challenges our perceptions and forces us to recognize the full scope of what makes Batman one of the greatest heroes of all time.
