Biscuit Krueger

Biscuit Krueger is a Double-Star Stone Hunter who was hired by Battera to clear the video game Greed Island following the auction for the game in Yorknew City. She prefers to be called "Bisky". She also served as the tritagonist for the Greed Island Arc. Biscuit likes to act and look like a young girl. Her overall aspect is reminiscent of a porcelain doll. She is often shown wearing a sleeveless dress and a bloomer with a mantle and skirt donned over it, along with gloves and plain leather shoes. She always has her hair tied up neatly and has changed its style at least three times. In her true form, she is a massive and extremely muscular woman several times the size of her preferred form. Although she claims to stay in her younger form to have the enemy underestimate her, the main reason is that she hates her original appearance. Regardless of which form she is in, Biscuit is very powerful. However, she does receive a tremendous power boost in terms of physical strength when she reverts (her Nen stays relatively unchanged between her forms). As a Royal Bodyguard, she wears her hair in a laced bun and dresses in a suit and tie. Biscuit has a devious personality. She has a tendency to use her cutesy appearance and demeanor to her advantage, whether it is for gathering information, getting what she wants, or acting innocent and helpless in combat to deceive her opponents. She jokingly said that if someone insists on using an honorific, they must call her -chama (-chan + -sama). Though in the beginning she was out to destroy Gon and Killua's friendship for fun, at the end of Greed Island she acknowledges that she is close to developing parental feelings toward the two of them.

She is prone to violent outbursts whenever she is left out of a conversation or reminded of her true age; Killua often becomes one of her victims because of his wisecracks about it. She can also get into arguments with people whose personalities differ from her own, such as Kurapika. Despite her sternness and deceitful personality, Biscuit is easily persuaded once someone compliments her appearance; when Kurapika acknowledges her looking like a princess, Biscuit immediately becomes flattered and agreeable. On the other hand, despite her hard training to reach it, she detests her true form, as it does not match her idea of femininity. As far as martial arts and training are concerned, Biscuit takes a stern and serious attitude towards her opponents and students alike. She has no qualms about killing an enemy fighter in combat, though she does not believe it is right outside of it and believes that lofty morals are an impediment in times of crisis. She unrelentingly pushes her students to their limits. She becomes deeply upset when she finds individuals with potential who squander it, and derives joy from polishing their abilities. As a Stone Hunter, she loves collecting precious stones, gems, and rare jewels and has a habit of naming them. She also loves getting money. Additionally, Biscuit expresses delight upon seeing handsome, young adult men and their figures; she was shown getting excited upon seeing a naked Hisoka. She also enjoys men's fashion magazines during her leisure time. Biscuit has introduced Nen exercises to develop her students' Nen abilities. Although only some of the exercises for Enhancement, Transmutation, and Emission were shown, she has actually devised ways to practice Manipulation and Conjuration as well. Biscuit is a Transmuter who also appears to be proficient in Emission, Enhancement, and Manipulation, despite the latter Nen type being the hardest for Transmuters to master. Her main Nen ability seems to combine Transmutation, Manipulation, and either Emission or Conjuration. She has developed exercises that allow her students to train in all five accessible categories, which should suggest that she has acquired a high level of skill in all of them, especially given her habit of demonstrating the exercises herself. Since she successfully performed her "Floating Hand" exercise, she is capable of firing an aura beam that can knock a Nen user back a dozen feet at the very least. Her theoretical knowledge of Nen extends to the specifics of abilities she herself does not possess, such as teleportation and parasitic-type abilities. Biscuit has mastered all the basic and advanced Nen techniques, with En being the only one she never showcased. She can combine Ten, Ren, Zetsu, Gyo, and Hatsu in her Ko, which had enough power to knock Gon back several meters and give him a nosebleed while he was using Ken, despite her moving her hand extremely slowly. She also claimed that if he had undone the technique instead of just relaxing it, she would have smashed his face in. She can maintain Ko for 30 minutes with no effort. She displayed Zetsu while hiding from the Bombers, as well as Ken, Shu, and In on other occasions. She can perform Ryu at such speed that Gon was unable to discern the changes in her aura flow as she punched. Her estimations are so accurate that in her late twenties she could already redistribute her aura with a margin of error lower than 1%.
