I was confused at first as to why Neferpitou's ability is that of a Torture Technician when cat people are usually used in Japan as fluffy Moe bait- I thought it was random. And then I happened to watch my own cats stalk and pounce on some toy mice and rip them apart, and then it hit me: he's a cold-hearted Torture Technician precisely because he's a catboy/part-cat Chimera Ant, and therefore would have had the ability beforehand as an actual cat with his prey.

Pakunoda is a Materialization-leaning Specialization-type nen user. Emission is diametrically opposed to Materialization, so she ought to be crap at it. And yet, she can very effectively use Materialized bullets, without them decohering and fizzling out as soon as they leave the barrel. She is just that good. ~ Pig_catapult
Or maybe the bullets go fast enough to not disperse before doing their purpose? Machi's Transformation, which is two steps removed from Emission, same as Specialization, and could keep strings going for a good dozen of meters.
But those strings are still attached on one end to her main aura, so they don't fall under Emission. It's only when a nen-object completely leaves contact with its originator that Emission skill becomes an issue, like when Machi sewed Hisoka's arms back on and told him to be careful, because her threads are much weaker when they don't attach back to her, or with Kurapika's Judgement Chain once the connecting line back to his hand breaks off.
Specialization types seem to be able to combine two different Nen types and use both effectively. Kurapika could deal with Uvo's enhancement powers not because Kurapika was just that good, but because his specialist power allowed him to use enhancement as though it was his main Nen type.
Specialization is frequently shown combined with Materialization and Manipulation (e.g., Kuroro uses Materialization to conjure his skillbook, but actually stealing the abilities is a Specialization power) because hatsu for those two nen types lend themselves easily to expanding to Specialization. Other characters as well sometimes combine two adjacent Nen types into their hatsu (e.g., Biscuit is primarily a Transformation user, but her hatsu, Cookie, also uses Materialization.), and can incorporate non-adjacent ones in some circumstances, but at a stiff penalty in effectiveness (e.g., Hisoka and Machi are both Transformation users, but they can use Emission to detach their gum/threads from their main aura in exchange for decreased range/tensile strength respectively). Kurapika's Emperor Time/"Absolute Mastery" ability is explicitly stated to be a property of the Scarlet Eyes, and implied to have been both unusual and a real Game Breaker power: When reminded of the Kuruta clan, both Ubo and Feitan, two of the Ryodan's biggest powerhouses, both recall first and foremost about them that "man, those guys were really strong". As the catch-all "everything else" category, Specialization isn't really something that (general) you can hold up one example for and say that it's representative of all or even most Specialization abilities, but Emperor Time is an especially poor example for setting as "standard". It's sort of like holding up the Sharingan as a representative standard for bloodline limits in the Naruto setting; nothing else really compares.
According to Hunter x Hunter wikia, objects materialized with aura can keep existing even being far away from the Conjurer. This seems pretty broken for Conjurers, since Emmision is their polar opposite type of Hatsu, keeping an aura-made object separated from the Conjurer's body should be near impossible, but there are other examples: Kurotopi's duplicates, Welfin's missiles, and Knov's doors.
A little bit of Fridge Horror here: Razor appears to be horrifically strong during the dodgeball match. He can throw a Nen-encased ball with enough force to injure or kill pro hunters. He bounces back Gon's ball (the same ball that upon being bounced, breaks several of Hisoka's fingers when Hisoka stops it with his Bungee Gum) with seemingly little ill effect. He can also destroy a small ship with a simple ball of Nen and scare the Genei Ryodan. And, according to him, he makes most spells work. Now, consider how much aura that must take. Just how strong is Razor?
STOP IT. YOU'RE FREAKING ME OUT.
The Greed Island spells (and items) have pretty ridiculous conditions imposed on them though. "You have to be on this particular island and arrive by this particular voluntary method which requires finding and using this particular game of which there are only 100 copies and then find this particular card from a random pack bought in this particular city." Not to mention the number limits for each card. Even an average nen user could probably get a lot of mileage by restricting something that much, and obviously Razor's at least above average. Also, he used a GM card to send the Ryodan away. No indication that they were exceptionally scared of him.
Phinks thinks to himself, "This guy's tough" and stops to talk, even though he has five Ryodan members behind him. Though it does go the other way too , since Razor is clearly impressed by the Ryodan. Even with conditions, making most spells work must still take a fair amount of aura. Conditions make the ability stronger, and do make a strong ability look like it takes more aura than it does, but don't necessarily decrease the amount of aura needed to use the ability in the first place. Kurapika still has to use a fair amount of Nen for his chains, but because of his self-imposed conditions they are much stronger than any conjured chains should typically be. Ditto for Kite's weapons system.
Aside from the restrictions, there are also a couple of things that we must take into account. First, god letters, which are basically patterns that you make and infuse with nen which let you use nen much more powerful than what you can normally use, which also let's us infer that you can infuse nen into objects and the nen will stay there and can be used for quite a few things, also it was stated that nen users can combine their abilities, like the bomber devil, and we know that at least 5 hunters worked together to create greed island. Taking all this into account, and also the fact that Razor mentioned that he was in charge of a system, Greed Island becomes much more plausible. They infused nen into quite a few things, pooling their nen abilities, and those were made with not only restrictions but with commands that automatically create the things in the world which is all managed by the hunters who created the game, they infuse the nen regularly to maintain their effects. Very impressive still but it does not require monstrous amounts of nen.
So at first it seems like the extra 'Hunter' in the title is a non sequitur, but then think about this. There are many types of Hunters; Gourmet Hunters, Beast Hunters, etc.; What type of hunter is Gon? Well, he's hunting for his father, so I guess that makes him a hunter who hunts hunters; a HUNTER HUNTER.
Though Togashi says the name came up from when he was watching a variety show, where one of the comedians repeats words twice. So it's really just a coincidence.
Actually, in that same interview he went on to explain that the title "Hunter Hunter" (as in a Hunter who hunts Hunters) was the seed that lead to Gon's entire motivation. The repeating comedian thing was just the spark.
Okay, during the episode where Gon rides the ship that leaves Whale Island to take the Hunter Exam, (the first Episode, in The Remake at least), there's this scene about this guy and this crate of apples or what. That scene wasn't made for randomness, or to show y'all how nice Gon is. Probably to get him in a position close to the Captain, but here's the point: The crate could have held anything. But it had to be apples. And not just apples, green ones. Translation? UNRIPE APPLES. Tell me how this is NOT a Shout-Out to Hisoka.
Except that green apples =/= unripe, necessarily. They could be granny smiths or golden delicious. If they really were unripe apples, that would mean they're cargo (since they'd ripen about the time they put into port to sell them) in which case they shouldn't be messing with them at all.
Although "green" is sometimes used as a term to describe someone inexperienced, so it might still be a valid metaphor.
Something about Greed Island always bugged me. There are hundreds, possibly thousands of NPC characters programmed in, but the island itself is known to be real. What's to say the NPCs aren't real people who have had some type of nen placed on them to control their actions? An entire island held captive for the sake of some game for hunters.
At least some of them respawn, like the Gold Dust Girl, and Razor has demonstrated the ability to create humanoids with his nen. Given that at least some of them convert into cards when "killed", it's plausible that they're actually nen constructs.
According to Killua, his family sent him to Heaven's Arena when he was 6 years old with the goal of reaching the 200th floor. While Killua ended up bending that a bit by only going through the first 199, the obvious purpose was to force him to learn Nen by fighting on the 200th floor. This becomes Fridge Horror when you realize just how brutal the "initiation" can be by people who know Nen there, to the point where people have died or become severely injured while there. And his family sent him, as a little kid, there with no concern for what would happen if he failed to learn.
Leorio, upon completing the Hunter Exam, could have obtained all the money he needed by selling his license immediately, either for his (fake) goal of getting rich or his (real) goal of going to med school and helping the needy (including his friend) out of his own pockets. But he didn't. He has something bigger in mind. (Either that, or he's holding on to his license for access to restricted nations and to make finding work easier).
Fridge Brilliance? Perhaps a Swiss Moment. What I'm trying to say is that it was a fridgey moment for me, but perhaps I'm just slow at the whole "weapon that can alternately be used as swords or nunchucks still = swordchucks" thing.
Chimera ant Queens are born when a Chimera ant King goes off and mates with another species, to produce a Queen that is a mix of species like all Chimera Ants that then goes off and starts making its own colony... So the Chimera ant queen seen in the Chimera Ant arc, the one that is humanoid, 2 feet tall and has nearly human levels of intelligence, without the human nature, is probably the product of one such Chimera Ant King and a human female.
Each of Killua's yo-yos weighs 50 kilos. Killua himself weighs less than 50 kilos. I know he has super strength, so it's not that surprising that he can easily run around with more than twice his body weight in his pockets, but how do his shorts even stay up?
Finding out that Ging can copy nen abilities that rely on physical attacks makes him getting hit by Leorio make way more sense. It's possible he lets himself get hit by new abilities to be able to copy them.
Leorio's Nen ability didn't make much sense to me at first. I figured that a doctor like Leorio would come up with a technique like Neferpitou's Doctor Blythe. Instead, he created a teleporting punch. Ging's explanation helped me realize that it was actually a perfect fit. Leorio may be a skilled doctor, but he's also a hotblooded and aggressive guy. Of course he would come up with a technique that can literally punch out cancer!
Due to Leorio being Put on a Bus for a few arcs, it can seem like his reaction to Gon's status after the end of the Chimera Ant arc is too extreme. But then, remembering Leorio's backstory and motivation makes it a lot more obvious that he would have such an emotional reaction to potentially losing another friend in such a way.
