Genthru

Genthru is the leader of the Bomb Devil trio, alongside members Sub and Bara; he is among the players trying to clear the game Greed Island. He is also known as the Bomber among Greed Island players.

Personality
Genthru is a psychopath. He lacks empathy for people at large, sans his friends Sub and Bara. Due to this, he is extremely self-oriented and is able to commit acts of mass murder with no difficulty. Genthru also disarms his enemies due to his constant composure--he rarely lapses from his calm demeanor.

Greed Island
Genthru first appears as a member of Nickes players alliance. He played a role as an informer and a high positioned member of the alliance for the previous five years. It is later revealed that he has placed a timebomb on every member of the alliance, blackmailing their lives for all the designated cards they held. Genthru does not keep his promise in the end and detonates all the timebombs, killing all the members of the allied group except Abengane the exorcist, who had managed to remove the bomb before the detonation.

Accompanied by his friends Sub and Bara, Genthru continues to amass the rest of the designated cards in order to win the game through any means. He is later defeated by Gon in a one on one fight in which Gon spots his weakness and overconfidence. However, Abengane later comments that Genthru is still stronger than Gon and that the boy would not have defeated him if he had not prepared for dealing with Genthru's abilities beforehand.
