Biscuit Krueger (ビスケット＝クルーガー Bisuketto Kurūgā?) first comes into the story on Greed Island. 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. She stays in her young girl form because she hates her original form's appearance. However, she does receive a tremendous power boost when she transforms to her real appearance. She helps Gon and Killua train while they are at Greed Island, leading them closer to the end of the game. Her goal on Greed Island is to get the gem found only in the game, Blue Planet. She is also the teacher of Wing, the man who first teaches Nen to Gon and Killua. After the events of Greed Island, she returns to help Gon and Killua train for their battles against Knuckle and Shoot during the Chimera Ant arc.
