Honestly, if you look back at the early days of Gon and Killua's journey, it’s easy to get distracted by the flashier stuff like the Chimera Ants or the chaos of Yorknew City. But everything—literally everything that makes the series what it is today—started at Heavens Arena Hunter x Hunter. It isn’t just a tournament arc. It’s a 251-story tall monolith of character growth and the moment Togashi decided to stop writing a standard battle manga and start writing a masterpiece.
You’ve got these two kids, fresh off the Hunter Exam, realization hitting them that they’re basically small fish in a massive, terrifying pond. They head to this giant skyscraper in the Republic of Padokia because, well, they need money and they need to get stronger. It’s a simple premise. You fight, you go up a floor, you get paid. But then you hit the 200th floor. That’s when the vibe shifts from "fun sports anime" to "existential dread."
The 200th Floor Wall and the Nen Reality Check
The 200th floor is where the series actually begins. Before this, Gon was just a kid with a fishing rod and a lot of heart. At Heavens Arena, he and Killua run into Hisoka’s "malice." It wasn't even a physical barrier; it was just raw aura. This is where Togashi introduces Nen, the most complex power system in anime history.
Wing, their reluctant teacher, is one of those characters who feels incredibly real because he's constantly stressed out by how fast these kids learn. He starts them off with the "Four Major Principles": Ten, Zetsu, Ren, and Hatsu. If you're a fan, you know these terms by heart, but back then, it was a lot to take in. The brilliance of this arc is how it grounds the supernatural elements. You aren't just born with "magic." You have to open your aura nodes, and if you do it wrong—like the "Initiation" the 200th-floor fighters try to force on Gon—you end up permanently crippled or dead.
Think about Gido, Riehlvelt, and Sadaso. These guys are basically the "bullies" of the 200th floor. They aren't legendary warriors. They’re washouts. They are people who reached the limit of their natural talent, got "initiated" by a Nen attack, and now spend their lives preying on newcomers just to keep their spot. It’s gritty. It shows the dark side of the Hunter world that isn't about glory, but about survival and ego.

Why the Fight Choreography Matters
Let’s talk about the actual scraps. Gon vs. Gido is a disaster at first. Gon gets thrashed because he’s stubborn. He tries to use his natural agility to dodge spinning tops—yes, literal Nen-infused tops—and he fails because he doesn't understand the fundamentals. It’s a rare moment where a shonen protagonist loses because they were stupid, not just because the enemy was "stronger."
- Gon vs. Hisoka: This is the peak of the arc. The buildup is insane. Gon just wants to land one punch so he can return Hisoka’s badge from the Hunter Exam.
- The Stone Slab Flip: Remember when Hisoka uses Bungee Gum to hide a pebble? Or when Gon flips a massive stone tile just to create a distraction?
- The Outcome: Gon "wins" the exchange but gets absolutely schooled in the fight.
Hisoka is the perfect antagonist here because he isn't trying to kill them yet. He’s "gardening." He’s waiting for them to ripen. It’s creepy, sure, but from a narrative standpoint, it sets a long-term goal that keeps the tension high for hundreds of chapters. Heavens Arena Hunter x Hunter uses the tournament format to establish the rules of the world so that later, in Yorknew, we don't need explanations—we just need action.
The Money, the Glory, and the Weird Economy
The economics of Heavens Arena are actually kind of hilarious if you think about it. You get a few bucks for the lower floors. By the time you hit the 100s, you get a private room that looks like a five-star hotel. If you reach the 200s, you don't even get paid for wins anymore—you fight for the glory of becoming a Floor Master.
There are 21 Floor Masters in total. They live in luxury on floors 230 through 250. Every two years, there’s a massive tournament called the Battle Olympia. It’s basically the World Cup for people who can kill you with their pinky finger. We never actually get to see the Battle Olympia in the main series (unless you count the non-canon The Last Mission movie, which, honestly, most fans don't), and that’s a classic Togashi move. He builds this massive world and then just moves on because the characters have somewhere else to be.

Subtle Character Shifts You Might Have Missed
While Gon is busy getting his ribs broken, Killua is going through a massive internal crisis. This arc is where we start to see the cracks in his assassin training. He's used to winning without effort. Suddenly, he's in a place where he has to think. He has to learn. His interaction with Zushi—the "one in a hundred thousand" talent who is completely outclassed by the "one in ten million" talent of Gon and Killua—is heartbreaking.
Zushi works hard. He’s a good kid. But he’s watching these two monsters breeze through concepts that took him years to grasp. It introduces a recurring theme in the series: there is always someone better, and sometimes, hard work isn't enough to bridge the gap between "talented" and "prodigy."
How to Scale Your Understanding of Nen Post-Arena
If you’re trying to wrap your head around how the power levels work after this arc, you have to look at the Hatsu types introduced during the Water Divination test:
- Enhancement: Pure strength. Gon’s bread and butter.
- Transmutation: Changing the property of aura. Killua’s future specialty.
- Emission: Detaching aura.
- Conjuration: Creating objects.
- Manipulation: Controlling things or people.
- Specialization: Anything that doesn't fit the others.
The Heavens Arena arc is basically a classroom. By the time the boys leave, they aren't masters, but they have the "license" to participate in the real world. They leave with a suitcase full of cash and a much deeper understanding of how dangerous their world actually is.

The Legacy of the Battle at the Summit
Years later, we get the Chrollo vs. Hisoka fight at Heavens Arena in the manga (around chapter 351). If you haven't read this, you're missing out on the most technical fight in the entire series. It uses the entire arena—the audience, the floor masters, the building itself—as a weapon.
It validates why Heavens Arena Hunter x Hunter is so legendary. It’s the only place in the world where two high-level Nen users can go all out in front of a crowd. It’s the ultimate stage. The fact that Togashi returned to this setting hundreds of chapters later shows just how much weight the location carries. It’s where legends are made, and it's where Hisoka finally met his match in a way that changed the series forever.
Actionable Insights for Fans and New Viewers
If you're re-watching or just getting into it, pay attention to the "empty" spaces. Heavens Arena is about what isn't said as much as what is.
- Watch the background characters: Many of the Nen abilities seen in later arcs are teased by the background fighters in the 200s.
- Analyze the "Ren" training: The scene where Wing uses his aura to "cut" through a wall is the perfect visual metaphor for how Nen bypasses physical durability.
- Track the money: Gon and Killua's financial status changes their motivations in the next arc (Yorknew/Greed Island). It’s one of the few anime where "getting rich" is a grounded, persistent goal.
- Don't skip the "boring" talk: The explanations Wing gives are actually 100% consistent throughout the next 300 chapters. If you understand them now, the Chimera Ant arc battles will make way more sense.
Heavens Arena isn't a detour. It’s the foundation. Without it, Gon is just a kid with a dream. After it, he's a hunter.
