Monev the Gale = Armix, Filigree Thrasher: Sentenced to prison after a life of crime following the destruction of July, Monev the Gale became a member of the Gun-Ho-Guns in order to take down Vash the Stampede. He wears a powered battle suit, turning him into an absolute force. The guns on his arms fire extremely fast due to the high pressure chambers on his back, enough to blow through entire buildings. He supports a rather sadistic personality, not caring about anyone who stands in the way of his goal.
E.G. Mine = The Peregrine Dynamo: He wears a power suit resembling a sphere and shoots various spikes from its surface. After Monev's defeat, he displays his dead body in order to intimidate Vash. This doesn't quite work however, because he is quickly defeated shortly after Vash shoots off his battle suit.
Dominique the Cyclops = Thalia, Heretic Cathar: She wears an eyepatch, concealing an ability known as the Demon Eye. When the eye is revealed, it causes hypnosis and sensory paralysis in her foes, momentarily stunning them and making her movements appear immediate. Although confident, she becomes discouraged due to Vashs' ability to withstand her Demon Eye by him focusing on pain from a previous injury.
Leonof the Puppet Master = Chainer, Dementia Master: Leonof is a puppeteer who works with life-size puppets. He is a cruel man; he shows disregard for life and takes delight in Vash's suffering. He views his art with high reverence to the point of obsession, calling his finished puppets "god-like". He can manipulate them to appear as real people, and uses them to do horrible things to people close to Vash the Stampede.
Chapel the Evergreen = Shadowheart, Dark Justiciar: Evergreen is a dogmatic and didactic person. Although he was forced to kill his former protege Wolfwood, he was deeply scarred by doing it going as far as to confront Knives. It's also mentioned by him that he hates being indebted to someone. He carries the parent version of Cross Punisher, though Chapel's splits into twin machine guns. He cares for Nicholas after Nicholas kills his abusive guardian.
Hoppered the Gauntlet = Vogar, Necropolis Tyrant: Prior to his joining the Gung-Ho-Guns, Hoppered was a cripple living in July, taking care of a mute and blind woman. The woman was killed in the destruction of July, leading Hoppered to seek revenge on Vash the Stampede, intending to go so far as to attempt to betray Knives' and Legato's orders that Vash the Stampede be tormented but not killed. Hoppered is capable of launching himself with great speed, allowing him to transform into a living projectile and plow virtually anything in his path. He also has a spiked hammer which he uses to move which doubles as a pistol, with which he has demonstrated remarkable skill and accuracy.
Midvalley the Hornfreak = Fain, the Broker: Midvalley is a musician with an impressive skill in playing his saxophone, Sylvia, with which he is able to synchronize sound waves with pain receptors in the human body, causing immense physical damage and even killing. He is also able to neutralize sounds by playing counter frequencies, creating absolute silence.
Gray the Ninelives = Karn, Legacy Reforged: Gray the Ninelives is the powerhouse of the Gung Ho Guns. He possesses immense strength and his armor is considerably resilient, being made of a combination of metal and flesh. Despite his size, Gray also proved to be quite agile. Gray has two guns, a pair of hand cannons that fire explosive cannonballs. What makes Gray the Ninelives so dangerous, however, is that it actually has nine lives because it's actually a robotic suit run by nine dwarf drivers. These drivers are well protected inside Gray's body and are distributed throughout the suit, in fact even the parts detached from the body can move on their own.
Rai-Dei the Blade = Toshiro Umezawa: Rai-Dei has learned what he calls the strongest and most lost sword style known as Jigenzan Ittou, a samurai style that includes evading your opponent and crushing him afterwards. He also has some weapons that help him in his mission to make Vash suffer, including a special samurai sword that allows him to create vibrant waves that can even go through walls and roller skates that give him incredible speed and mobility, to the point of being able to evade many of Vash's blows. Rai-Dei is undoubtedly one of the fastest members of Gung Ho Guns.
Livio the Double Fang = Jerren, Corrupted Bishop
: Livio of the Double Fang is a childhood friend of Nicholas D. Wolfwood, a disciple of Chapel and a member of the Gung-Ho-Guns from the Eye of Michael. Livio has what is assumed is Dissociative Identity Disorder and has an alter known as Razlo the Tri-Punisher of Death, who is treated as a separate member of the Gung-Ho Guns. As a member of Eye of Michael, Livio has increased muscle strength, enhanced senses and stronger bones, allowing him to perform feats of great strength and agility.
Razlo the Tri-Punisher Of Death = Ormendahl, the Corrupter
: Razlo the Tri-Punisher Of Death is Livio the Double Fang's alter, treated as another member of the Gung-Ho-Guns from the Eye of Michael. Razlo was created to take all of the abuse given by Livio's parents, allowing Livio to not be aware of the abuse. If Livio is considered the host of his system, Razlo seems to be his persecutor/protector alter; he commits poor, harmful actions as a way to protect the system itself. Razlo often appears after Livio has suffered intense pain or trauma, and most of the time commits violent acts against the people who hurt him and Livio when he is in control. Razlo led Livio to join the Eye of Michael, promising that the organization could give them a purpose in life.
Zazie the Beast = Skrelv, Defector Mite: Zazi lived on the planet Gunsmoke even before the nailed people, he was the leader of the legion of insects inhabiting the entire planet. Zazie the Beast is actually a legion of insects that were the original inhabitants of planet Gunsmoke. The first other being they ever saw was Knives, who interested them greatly. It is unknown how they became members of the Gung Ho Guns, but from what they said through their hosts, they at first had hoped to live harmoniously with humans and plants, but they eventually decided they'd be more inclined to living with plants likes Knives.
Elendira the Crimsonnail = Ink-Eyes, Servant of Oni: Elendira the Crimsonnail is referred to as the lost thirteenth in the manga. She is considered the strongest of the Gung-ho-Guns. Elendira shoots giant red nails from a large briefcase that transforms into a crossbow, with preternatural force and speed. She is also capable of projecting her killing intent to seemingly create illusions of destruction in her prey and break their will. As the strongest Gun, Elendira is the only one who can stand up to Legato Bluesummers, but she also regards Legato with a great deal of jealousy, noting that the fact that Legato alone of the followers of Knives is not assigned a number as a part of the Gung-ho Guns suggests that Legato is more important to Millions Knives.
