Arc Physical Strength Without Armor: Skeleton Knight Power Analysis
When people talk about overpowered isekai protagonists, Arc from Skeleton Knight in Another World is often mentioned alongside some of the genre’s biggest monsters. At first glance, it’s easy to assume that most of his power comes from the legendary Beltran Armor. After all, he looks like a walking fortress covered in shining mythical equipment capable of tanking attacks that would instantly destroy ordinary warriors.
But after rewatching the anime and revisiting several parts of the source material, I’ve come to a different conclusion. The armor is incredible, sure, but I believe many fans underestimate just how absurdly powerful Arc actually is without it.
The real question isn’t whether Arc becomes weaker when his armor is removed. Of course he does. The better question is this:
Would Arc still be one of the strongest physical fighters in his world without any armor at all?
My answer is a confident yes.
The Biggest Misunderstanding About Arc’s Power
One thing that often gets overlooked is the role of the Beltran Armor itself.
Many viewers treat it as the source of Arc’s strength, but the armor mainly serves as an enhancement package. It improves survivability, boosts certain combat attributes, and grants useful defensive effects. It doesn’t magically transform a weak character into a powerhouse.
Think of it like putting premium racing tires on an already powerful sports car. The tires improve performance, but the engine is still doing the heavy lifting.
The Beltran Armor primarily provides:
- Massive defensive bonuses
- Health regeneration
- Resistance against curses
- Additional attack enhancement
- Reduced damage from specific magic elements
These are incredible benefits, but they don’t create Arc’s raw physical power from nothing.
Arc Was Already a Max-Level Monster
Before arriving in the fantasy world, Arc wasn’t an average player.
He had already reached the maximum level available in the game. His character build was essentially optimized to an extreme degree. When the game became reality, those statistics weren’t reset or nerfed. They became part of his actual body.
That means Arc’s strength, durability, agility, and endurance exist independently from his equipment.
Even completely unarmored, he still possesses the physical attributes of a max-level Holy Knight.
In practical terms, that places him far above:
| Character Type | Compared to Unarmored Arc |
|---|---|
| Ordinary Human Soldier | Completely outclassed |
| Skilled Adventurer | Significant disadvantage |
| Elite Knights | Still weaker physically |
| Large Monsters | Arc remains competitive |
| High-Tier Boss Creatures | Depends on abilities |
This is what makes Arc so frightening. The armor makes him harder to kill, but the body underneath is already a walking raid boss.
The Skeleton Body Is Actually a Huge Advantage
A lot of people hear the word “skeleton” and immediately assume weakness.
That’s logical in real life.
In fantasy anime? Not so much.
Arc’s skeletal form gives him several advantages that many fighters simply cannot replicate.
No Physical Fatigue
Humans get tired.
Muscles burn. Stamina drops. Reactions slow down.
Arc doesn’t have those limitations.
He can continue applying maximum force for extended periods without experiencing the same level of exhaustion as living opponents.
No Pain Response
Pain is one of the body’s natural limiters.
Most people never use their full strength because the body instinctively protects itself.
Arc doesn’t have this problem.
If he needs to exert maximum force, there’s no pain mechanism telling him to stop.
Naturally Resistant Structure
While his bones can still be damaged, many attacks designed to injure flesh become significantly less effective.
Stabbing a skeleton simply doesn’t produce the same result as stabbing a human.
That alone creates unique advantages in combat.
The Feats That Convince Me
The biggest evidence comes from Arc’s actual combat performances.
There are multiple moments where his strength appears far beyond what equipment alone could reasonably explain.
Effortless Weapon Handling
Arc regularly wields an enormous sword that most normal people couldn’t even lift properly.
What stands out isn’t merely that he uses it.
It’s how casually he uses it.
He swings massive weapons with a level of comfort that suggests overwhelming base strength rather than equipment-assisted movement.
Casual Physical Attacks
Some of my favorite moments involve Arc accidentally demonstrating how absurdly strong he is.
Simple gestures become dangerous.
Minor strikes send enemies flying.
What would be a harmless shove from an ordinary person becomes a devastating impact when Arc does it.
These scenes often feel comedic, but they reveal an important truth:
Arc constantly suppresses his actual power because he knows how destructive he can be.
Stopping Massive Creatures
One of the clearest indicators of his physical capability is his ability to resist charges from gigantic monsters.
Even if magical equipment absorbs part of the impact, his body still needs enough structural strength to survive the collision.
Without extraordinary physical stats, those encounters simply wouldn’t work.
Arc’s Biggest Weakness Isn’t Strength
Ironically, Arc’s most obvious flaw isn’t physical power.
It’s technique.
This is something I genuinely enjoy about his character because it prevents him from becoming boring.
Despite possessing ridiculous stats, Arc isn’t a lifelong martial arts master.
He’s a gamer who suddenly found himself living inside a fantasy world.
Against highly skilled fighters, his movements can be predictable.
There are moments where experienced warriors demonstrate superior combat fundamentals despite being physically weaker.
That’s what makes Arc interesting.
He’s often winning because of overwhelming numbers rather than flawless skill.
And honestly, that feels realistic.

What Happens If Arc Loses His Skeleton Form?
Another fascinating detail is Arc’s true racial identity.
Underneath the skeletal appearance, he’s actually connected to a Dark Elf avatar.
Whenever circumstances temporarily reveal that form, we get a glimpse of what Arc would be like without the undead body.
The important takeaway is that his power doesn’t suddenly disappear.
He loses some undead-related advantages, but his level and stats remain intact.
Dark Elves are already physically gifted compared to many races in the setting.
Combine that with max-level attributes and Arc would still rank among the strongest warriors around.
My Final Verdict
As a longtime anime fan, I’ve always felt that Arc’s armor receives too much credit.
Yes, the Beltran Armor is legendary.
Yes, it massively improves his survivability.
But after looking at his feats, his level, and the way the world’s mechanics operate, I think the truth is pretty clear.
Arc without the Beltran Armor is still an absolute monster.
He might lose some defensive protection, regeneration, and elemental resistance, but his core strength remains intact. The armor amplifies an already terrifying character rather than creating one.
If Arc ever fought completely unarmored, I don’t think most opponents would celebrate.
They would simply discover that the giant skeleton underneath the armor was the real threat all along.
