Gon is the protagonist of Hunter x Hunter and easily one of the most talented people that we’ve seen in the series to date. Although he’s young, he holds tremendous potential within himself which had already been acknowledged by many.
During the Chimera Ant arc, we got to see a glimpse of what Gon would be like as an adult and the display we got indicated that he would turn into a phenomenal fighter who few can hold their own against.
10 Can Rival: Hisoka
Hisoka is one of the former members of the Phantom Troupe who has played a major role in the series to date. He’s an incredibly powerful individual, thanks to his Nen ability, known as Bungee Gum.
Hisoka looks forward to the day Gon matures as a fighter and fights him. Although he appears to be weaker than adult Gon, he isn’t the finished product himself either. By the time the two fight, Hisoka will have gotten much stronger and will be able to rival Gon.
9 Can’t: Leorio
One of Gon’s closest friends, Leorio is one of the Zodiacs who also aims to become a doctor. Although not highly proficient in Nen usage, he’s still decent at it. It is evident that Leorio is much weaker compared to the others in his group.
Even if he trains for all his life, him being able to match Adult Gon is nigh impossible. The power difference between the two is massive as it is and with time, Gon will only get stronger at a faster rate.
8 Can Rival: Killua Zoldyck
Killua is one of the members of the famed group of assassins known as the Zoldyck family and also Gon’s best friend. He’s an incredibly powerful character who specializes in Transmutation type Nen ability.
Killua is arguably stronger than Gon right now and is said to hold equal potential to him. As an adult, it is a certainty that Killua will be able to rival Gon in terms of strength. Given that he’s incredibly smart, we think he can possibly defeat him as well.
7 Can’t: Meleoron
Meleoron was once a Squadron Leader of the Chimera Ants. Although his rank indicates that he’s someone with high strength, Meleoron was actually weak and he considered himself to be on the same level as a Chimera Ant foot soldier.
His Nen ability, however, is extremely useful and it allows him to make himself invisible as long as he holds his breath. He can also extend the invisibility to others, however, only for a set amount of time. It is quite obvious that Meleoron stands no chance against adult Gon.
6 Can Rival: Kurapika
Another one of Gon’s friends, Kurapika is one of the Zodiacs, just like Leorio. He’s an incredibly strong Nen user who excels in Conjuration based techniques.
When using Emperor Time, Kurapika gains compatibility with all the Nen types, meaning he can fully master everything. He’s proven to be powerful enough to fight and defeat the likes of Uvogin of the Phantom Troupe, meaning his strength is possibly beyond Gon as well. As an adult, it is highly likely that Kurapika will be comparable to Gon and Killua since he has a lot of room to grow.
5 Can’t: Nobunaga
One of the members of the Phantom Troupe, Nobunaga is known to be a decent swordsman and an admirable Nen user. He appears to be well versed in the usage of En and his other skills make him quite useful in a fight as well.
Nobunaga, while strong, is nowhere near the level of a Chimera Ant Squadron leader like Leol. Meanwhile, Gon was comparable to Meruem, the King of the Ants, himself. It is quite clear that Nobunaga would be no match for adult Gon.
4 Can Rival: Ging Freecss
Ging is Gon’s father and a double star Hunter, which means he’s way more experienced than his son. Although we’ve seen little of his abilities, we do know that he’s one of the top 5 Nen users in the entire series, based on what Isaac Netero thought of him.
Ging’s powers haven’t been revealed yet but we believe that he’ll be more than capable of matching Gon in a fight. It is possible that Ging could be as strong as Netero, which means Gon would have a worthy competitor in his father.
3 Can’t: Knuckle
Knuckle is one of the students of Morel and he played a major role in the Chimera Ant arc of the Hunter x Hunter series. Knuckle is known to be extremely powerful, as seen when he managed to defeat Gon in a fight.
Although he’s stronger than Gon as of now, Knuckle would definitely not be able to defeat him as an adult. In his fight against Menthuthuyoupi, we saw Knuckle struggle, while Gon manhandled Neferpitou without any trouble whatsoever.
2 Can Rival: Isaac Netero
Isaac Netero was the former chairman of the Hunter Association and also the strongest known Hunter in the series to date. In his prime, he was known to be at least twice as strong as he was in his old age when he fought Meruem.
Netero was able to rival Meruem in battle, which is something even the King acknowledged. Had he been alive, he would’ve been able to rival Gon in a fight as well and we’re certain that his chances of winning would’ve been quite decent.
1 Can’t: Kalluto
Kalluto, just like Killua, is a member of the Zoldyck family. Currently, he serves as a member of the Zoldyck family and he’s exceptionally powerful. Compared to Killua, however, Kalluto isn’t all that strong.
Going off of that, it wouldn’t be a stretch to say that Kalluto is also weaker than Gon Freecss right now. His chances of rivaling adult Gon are extremely low and if the two were to ever fight, the battle would end in Gon’s favor within minutes. Nonetheless, Kalluto isn’t one to be underestimated.
Gon is the protagonist of Hunter x Hunter and one of the most powerful characters — especially as an adult…
