The Twelve-Year-Old Assassin's Rebellion: Meeting Gon
Killua Zoldyck first captivates audiences as a mischievous yet incredibly capable twelve-year-old. Introduced during the grueling Hunter Exam, he quickly stands out with his silver hair, blue eyes, and an air of both boredom and lethal potential. Born into the notorious Zoldyck family of assassins, his life until this point was one of brutal training and isolation, designed to mold him into the perfect heir. Yet, beneath the cool demeanor lay a yearning for something more – freedom and friendship. His decision to run away from home and take the Hunter Exam was his first major act of rebellion, setting the stage for everything that followed.
It's during this exam that he encounters Gon Freecss, and their immediate, almost effortless bond becomes the cornerstone of the entire series. Their friendship challenges Killua's ingrained conditioning, forcing him to confront his violent past and the psychological barriers his family, particularly his brother Illumi, had erected.

Rapid Maturation: Mastering Nen and Physical Prowess
Following the Hunter Exam, Killua's age continues to advance alongside his skills. Under the tutelage of Wing and later the formidable Biscuit Krueger, he rapidly learns and masters Nen, demonstrating an innate talent for the Transmutation type. This period is critical for his development, as he not only hones his combat abilities but also strengthens his resolve and independence. His physical stats, initially 158 cm tall and 45 kg, begin to see minor changes as he trains relentlessly, showing an incredible aptitude for absorbing pain, resisting poisons, and enduring massive electrical shocks, all hallmarks of his assassin conditioning.

Breaking Chains: The Chimera Ant Arc and Self-Discovery
Perhaps the most significant period of growth for Killua occurs during the harrowing Chimera Ant arc. Although his exact age isn't explicitly stated to have jumped dramatically, the experiences within this arc accelerate his maturity and emotional intelligence far beyond his years. Confronted with unparalleled threats, Killua is forced to push past the mental blocks imposed by Illumi, which had always compelled him to flee from stronger opponents. He accomplishes this by bravely removing the needle Illumi had implanted in his brain, a symbolic and literal act of self-liberation. This breakthrough unlocks his full potential and allows him to develop Godspeed (神速, Kanmuru), a Hatsu that grants him immense speed and reflexes.
This arc is a crucible for Killua's personality, transforming him from a hesitant, self-doubting individual into a confident, self-reliant protector. His unwavering loyalty to Gon shines brightest here, as he consistently puts Gon's well-being above his own, making crucial strategic decisions and even confronting his own deep-seated fears.

His quick thinking and pragmatic nature are always present, but they become tempered with a newfound emotional intelligence that allows him to navigate complex interpersonal dynamics, especially when Gon is in distress.

Godspeed and Beyond: His Signature Abilities
Killua's Nen abilities are among the most distinctive in the series, evolving significantly as he matures. His Transmutation type aura, allowing him to convert his aura into electricity, is initially shown through simple applications but quickly progresses to advanced techniques. Godspeed, developed during the Chimera Ant arc, is the pinnacle of his electrical Hatsu, granting him incredible bursts of speed for attack and evasion. This ability is not just a power-up; it represents his mental breakthrough and commitment to protecting his friends.
Beyond Nen, his assassin training has instilled in him extraordinary agility, stealth, hand-to-hand combat skills, and an unparalleled tolerance for pain and various harmful substances. He effectively uses a skateboard and later yo-yos as tools to complement his fighting style, showcasing his adaptability.

This act of profound love and determination showcases the ultimate evolution of his character. He leverages Alluka's enigmatic powers to heal a critically injured Gon, demonstrating not only his strategic brilliance but also his absolute devotion.
Following Gon's recovery and the meeting with his father, Killua makes a momentous decision: to part ways with Gon and travel the world with Alluka, protecting her and exploring their future together. This choice marks the beginning of a new chapter, where Killua fully embraces his role as a guardian and a free spirit, no longer bound by his family's dark expectations.
