Behemoth (ベヒモス,Behimosu?) is a high ranked mercenary player in the VRMMO, Gun Gale Online, who is usually hired as a bodyguard for player groups with money but no perseverance. Behemoth uses a heavy «GE M134 Minigun» as his weapon of choice.
Behemoth first appeared wearing a camouflage cloak and coat, which hid his equipment from the view of other players, while massive goggles covered his face and hid his expression. He has a huge body, broad shoulders, is nearly 2 meters tall and seemed to be wearing a large backpack at first, but this turned out to be his GE M134 Minigun, connected to a large capacity ammunition box via a belt. Unlike the other members of the Mob hunting party he was in, his lips were tight, without a slightest movement and he was walking slowly and silently in the back, giving off a feeling of pressure to an experienced player like Sinon. In battle, he forms a fierce smile. After Sinon's shot hits his goggles, it is revealed that he has grey eyes, blazing with light, as he formed another fearless smile, and that he has a rough face.
Behemoth is a well-known minigun user in GGO and is said to be invincible in various group battles, if he gets adequate support from his teammates. He did not, however, appear in the Bullet of Bullets tournaments, as his Minigun and 500 rounds of ammo put him overweight, which prevents him from being able to run during the match and makes him an easy target for snipers, especially since the BoB tournament is a solo encounter, meaning that there are no teammates to support him if he joins.
Behemoth is a mysterious, silent, and expressionless person when not in battle. He is shown to be a calm and collected person, as shown by how he is not troubled or confused by the sudden death of his teammate and does not even take 3 seconds to locate Sinon. He likely enjoys firefights and killing other players, which is shown in the form of a fierce smile as takes his Minigun to open fire at the attacking PvP squadron. He is also an experienced and quick-witted person, as he is able to quickly read Sinon's plan of finding a suitable location for sniping and is able to locate and aim directly at her new location.
Behemoth appeared as a new member of a Mob (monster) hunting party that Dyne and his anti-personnel squadron (PvP guild) had ambushed a few days ago and attempted to ambush them again. Due to his cloak that was hiding his equipment, he was not considered a major threat by Dyne, so he ordered Sinon to snipe the party's Minimi user, who was a more apparent threat. After Sinon killed the Minimi user and revealed her position to the party, Behemoth did not show any sign of confusion and calmly avoided Sinon's second shot, which was directed at him. Afterwards, he removed his cloak, revealed his Minigun and formed a fierce smile, as he began firing Ginrou's attacking group of three, killing Ginrou in the process. He kept pushing Dyne's squadron back with his strafing fire, as the party's members close the distance to the squadron. At that point, Sinon regrouped with Dyne's squadron, though barely avoiding Behemoth's fire, and devised a plan of action. As the squadron split into two and attacked from the left and right, Behemoth aimed at the group attacking from the left and killed one of the squadron's member, but then he noticed that Sinon was ready to fire at them. After Sinon failed to snipe him, he aimed the Minigun at her, but was stopped by Dyne firing at him, giving Sinon time to escape. Although Sinon used the cover of the veil of dust created by Dyne's suicide attack to move to a sniping point, Behemoth was able to predict Sinon's plan and thus aimed directly at her new location before she has even acquire him on her scope. But, before he was able to kill the sniper, she jumped out from the window. Although she lost her leg to Behemoth's blast, Sinon was able to shoot Behemoth in the face directly from above, where he was unable to hit her, killing him instantly.
