Imori

 Imori' (イモリ, Imori'') is the youngest and weakest among the Amori Brothers and is examinee #198 in the 287th Hunter Examination.

First Phase
During the first phase, Satotz's marathon, he and his brothers aid Tonpa in driving off some of the weaker contestants, such as Nicole, showing that they've known Tonpa for some time, and have likely worked together with him before.

Fourth Phase
During the fourth phase of the exam, Imori stalks and attacks Killua in order to claim his badge. However, Killua easily takes his badge then overpowers and holds Amori hostage forcing Umori to surrender his badge. Killua then throws two of the brothers' 3 badges into the woods as he did not need them, failing the trio.

Greed Island arc
While Gon is training on Greed Island, Imori and his brothers attend the 288th Hunter Exam, only to be easily knocked unconscious together with the rest of the candidates in the first phase by Killua. Seeing the tremendous gap in abilities between Killua and themselves, despite the boy being much younger than them, they decide that they will never retake the Hunter Exam.
