Gon, the protagonist of the anime and manga series “Hunter x Hunter,” is initially portrayed as a physically strong and talented fighter without the use of Nen. While Nen is an important aspect of the series, it is not the only determinant of strength.

Gon’s physical strength, endurance, and agility are a result of his intense training, natural talent, and determination. He has been shown to possess incredible physical abilities, such as lifting enormous boulders, running at high speeds, and enduring extreme conditions.
Moreover, Gon has received combat training from his adoptive father, Ging, a renowned hunter who is also exceptionally skilled in combat. This training has honed Gon’s natural combat instincts and skills.
Additionally, Gon’s battle against powerful opponents, such as Hisoka and the Chimera Ants, has pushed him to the brink of his physical and mental limits, allowing him to tap into his hidden potential and push his abilities beyond what is normally possible.
While Nen is undoubtedly a powerful tool in the Hunter x Hunter universe, Gon’s strength and abilities without Nen are a testament to his natural talent, intense training, and sheer willpower.
