Biscuit Krueger

Biscuit Krueger is an elite Double-Star Hunter and a legendary master of Shingen-ryu kung fu, famously known for being Wing's original Nen teacher.

Despite her true form being a massive, heavily muscular 57-year-old woman, she deliberately transmutes her appearance into that of a fragile, doll-like young girl to trick her opponents and avoid unwanted attention.

Biscuit enters Greed Island with the selfish intention of obtaining a rare gemstone, but upon witnessing Gon and Killua's unpolished potential and reckless combat habits, her maternal and mentoring instincts kick in.

She puts the duo through an exhausting, meticulously designed training regime that fundamentally refines their mastery over advanced Nen techniques.

As a Transmutation user, her primary ability manifested is Magical Esthetician, a specialized Nen massage therapist that speeds up physical recovery and relieves exhaustion, allowing her students to train relentlessly.

Behind her deceptive, cute persona lies a fierce, highly calculating warrior who shows zero mercy to those who underestimate her.
