Biscuit Krueger

Biscuit Krueger (ビスケット＝クルーガー, Bisuketto Kurūgā?) is a pro-hunter that enlisted in clearing the video game Greed Island, the same time Gon and Killua did after the auction for the game in Yorkshin. She prefers to be called "Bisky". In addition, she was the teacher of Wing, the man whom first taught Nen to Gon and Killua. According to herself, she started learning Nen at the age of 17, other than that there is not much revealed about her past.

Personality
Biscuit has a devious personality, she initially uses her cutesy to her advantage whether it's for information gathering, getting what she wants, or even in combat by acting innocent and helpless so most people will usually put their guards down around her. However as a Nen teacher she has a stern and serious attitude towards her students. She's also prone to violent outbursts whenever being left out of a conversation (between Gon and Killua) or being reminded of her true age with Killua often being the victim because of his wise-cracks about it. Biscuit loves collecting rare jewels and getting money, she also has a liking in seeing nude men, from seeing Hisoka naked up to reading a magazine filled with it while helping Gon and Killua train themselves againts Morel's apprentices.

Appearance
Biscuit likes to act and look like a young girl oftenly shown wearing a cutesy dress with lace, frills and ribbons, She wears a sleeveless dress and a bloomer with a mantelet and skirt worn over it, along with gloves and plain leather shoes. She always has her hair tied-up neatly and have changed its style 3 times throughout the storyline. She is tall and muscular in her original adult form despite this she still appears younger than her age since of her mastery of nen. Although she appears to be a little girl, in her true form she is actually a massive and extremely muscular woman several times the size of her preferred form. The only reason she stays in her girl form is because she claims she hates her original form's appearance.[15] Regardless of which form she is in, Biscuit is very powerful. However, she does receive a tremendous power boost when she transforms to her real appearance.

Greed Island Arc
Her goal in the game was to get a gem that can be only found in that island called "Blue Planet". She was intrigued by Gon's attitude and decided to to observe the young hunter until they encountered Binolt, a black list hunter turned murderer. She came to conclude that Gon and Killua will get themselves killed if she left them alone. After defeating Binolt, Gon and Killua asked her to put her jewel hunt on hold and teach them Nen-which was already her intention. Biscuit taught the two about the Advanced Techniques of Nen which took three months before doing any actual Designated Card hunting. When Killua left the island to take the Hunter Exam, Biscuit and Gon trained alone to develop Gon's Hatsu abilities which resulted in three Jajanken techniques.
