Genthru (ゲンスルー, Gensurū) was the leader of the Bomb Devils, alongside members Sub and Bara;[1] he is among the players trying to clear the game Greed Island. He is also known as the Bomber (爆弾魔 (ボマー), Bomā) among Greed Island players.[2] Genthru serves as the main antagonist of the Greed Island arc.


Genthru G.I Design (2011 Anime)

Genthru's 2011 anime design

Genthru is tall and very thin. He has lanky arms. In the 1999 series, he has brownish red hair, while the 2011 series gives him blond hair. He has a pointed chin and angular glasses that give him an evil look complimenting his chin and cheekbones, giving him a generally pointed look.


At the beginning Genthru shows himself as gentle, friendly and willing to stop the Bomber and finish the game, but after he reveals himself as the real Bomber, he shows his true colors.

Genthru enjoys killing. Lacking compassion for people at large, with the possible exception of his friends Sub and Bara. Due to this, he is extremely self-oriented and is able to commit acts of mass murder bordering on terrorism with no difficulty. Genthru also disarms his enemies due to his constant composure—he rarely lapses from his calm demeanor.

However, he volunteers to roll the Risky Dice when one of his companions is readily willing to do it, citing a promise to "share risks equally". Later, he also agrees to hand Breath of Archangel over to Gon and company, on the condition that they use a duplicate Archangel to heal Bara.

Nickes Introducing Gon & Killua

Genthru as a member of Nickes' group

Genthru is introduced as one of the members of Nickes' players alliance, and plays the role of an informer and a high positioned member of the alliance for five years. He explains the basic information about Greed Island and the spell cards to new players, such as Gon Freecss, Killua Zoldyck, and Biscuit Krueger. He also gives warning about other players, specifically someone called the "Bomber".[2] Genthru is aware of the spell put on Killua earlier by a player and proposes to remove it if he and Gon join the group, but the boys refuse the offer.[3]

Genthru Killing Jispa

Later, in the alliance member cave, Nickes makes an announcement that they've nearly collected all of the restricted slot cards. Then Genthru makes his own announcement revealing that he's the Bomber and he has placed a time bomb on each and every member of the alliance. After this shocking revelation Jispa tries to subdue Genthru, but fails and his face is destroyed by Genthru's Nen ability Little Flower. Before leaving the hideout he explains how to remove the bombs by touching him and say, "I caught the Bomber" or turn over all of their cards to him. Genthru then escapes the base using a Leap (G.I card).[1] Puhat, an alliance member, tries to negotiate with Genthru alone, but fails and is killed by Genthru.[4] When the cards are given, Genthru does not keep his promise and detonates all the time bombs, killing all the members of the allied group,[5] aside from Abengane the exorcist, who had managed to remove the bomb before the detonation due to his exorcism ability and Cuzco.[6]

Bombers Release

"Releasing" the bombs

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. While Gon were busy with Razor's dodgeball game, he and the other Bombers killed Kazsule's team. He informs Tsezguerra of this and discovers that Gon has one of the cards he needs. Gon refuses to back away, challenging him instead.[7] Tsezguerra's team delays Genthru's team for three weeks so Gon and the others could think of a plan.[8] Once Genthru goes after him, he uses his remaining Accompany cards to pursue him. He is isolated with Gon, and gets into a one-on-one battle.[9]

Based on Gon's movements, he deduces that someone who knew of his abilities was alive. At first, he overwhelms Gon due to the difference in skill.[10] At the point that Gon is supposed to go with the plan, the boy does not, allowing Genthru to use Little Flower to detonate his left hand. However, Gon used the opportunity to kick Genthru in a weakly-guarded place. He manages to avoid being hit head-on with a Jajanken: Rock by tripping on a rock. Deciding to outwit Gon, he pretends to surrender to get Gon near him with his Book out. He proceeds to crush the boy's throat so that he could not utter "book" again, and dispel it. Enraged, Gon soaks Genthru with gasoline to nullify his Little Flower.[11] Out of options, he decides to use Countdown. Before he can complete the conditions, however, Gon uses Jajanken: Rock on the ground, revealing it was a covering for a pit. Genthru falls and is trapped in the pit, where Gon uses Jajanken: Rock to defeat him.[12]

Following the battle, he is tied up and brought to an open field with his defeated partners. He requests that Breath of Archangel be used on Bara, who had been severely injured by Biscuit.[12] While he is tied up, Abengane touches him and says "I caught the Bomber", releasing the bomb. 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.[13]

Abilities & PowersEdit

Genthru has demonstrated that he is quite a formidable foe on numerous occasions. Tsezguerra had even surmised that he could only hold Genthru off for a limited amount of time before he reached Gon, further emphasizing the threat he posed to the group. He has shown both considerable agility in reaction and Nen as well as the the ability to manipulate even the most clever individuals as he managed to fool the entire group of Greed Island players comprising Nickes' group for over 5 years, all the while planting bombs on each one.

Enhanced Strength: With only one punch to the face, Genthru knocked Gon off his feet and sent him flying a few meters from his original position.[10][14]

Enhanced Speed: Genthru can move fast enough to catch Gon by surprise.[10][14][15][11]

Keen Intellect: Genthru is moderately analytical and an accomplished manipulator. His strategies often include intimidation to coerce other players into doing what he wants.

Proficient Hand-to-Hand Combatant: Genthru overpowered Gon in combat during their confrontation,[10][14][15][11] receiving a critical hit only due to his underestimating his opponent.[12]


Genthru is a Conjurer with remarkable skills in Transmutation. He is a capable, experienced and dangerous Nen user who is able to use all five Nen types, either in one of his Hatsu abilities or in combat. He makes ample use of Ryu in combat, both to strike and defend himself from Little Flower. The fact that this ability has no effect on him while it is often lethal to others, proves that he has a great amount of aura and is able to control it most efficiently.

However, his abilities have a few flaws that experienced or forewarned opponents may exploit to their advantage: for example, one can minimize the damage from Genthru's Little Flower by using Ryu (or similar techniques like Ko) on the part touched by him. Furthermore, since he uses Gyo in his hands in order to protect himself, the rest of his body is coated with little protective aura. When he uses Little Flower on both of his hands, any Nen-enhanced attack on the rest of his body would result in severe damage.

Genthru's Nen Type: Conjuration
Type: Transmutation Little Flower (一握りの火薬 (リトルフラワー) A Handful of Gunpowder)
Nen 1 Genthru gives his aura explosive properties, creating small yet deadly detonations in his palms.[1] He employs this ability offensively by grabbing hold of an opponent and triggering the explosion.[1][5][15][11] If used correctly, this move can easily kill a Nen user in one shot.[5] He can only grasp things as large as a basketball.[1] He protects his hands from the explosion with Gyo.[15] Because of this, the resulting explosion is significantly less powerful than Countdown. Aside from combat, Genthru uses this ability as a deterrent to threaten other players or discourage them from trying to touch him.[4]
Type: Conjuration, Emission, and Manipulation Countdown (命の音 (カウントダウン) Sound of Life)
Nen 2 Genthru can attach a bomb to a victim by following two conditions,[4] in no particular order:[12] he must touch the target while saying the word "Bomber" and explain both of his abilities in full[4] (and in proper sequence).[1] The bomb is then conjured and its countdown timer starts at 6000. The timers are linked to his victims' pulses, counting down faster if their heart rates increase.[4] When it reaches 0, the target explodes from the inside, the blast being ten times more powerful than that of Little Flower.[12] In order to nullify this ability, the victim needs to touch Genthru and say "I caught the Bomber".[4] Genthru can detonate the bombs at anytime when touching thumbs together with Sub and Bara, with all three saying the word "Release" (解放 (りりース), Rirīsu).[5] Though he is a Conjurer, he also employs Emission and Manipulation to make this ability possible.[4]
