Monev the Gale is the first member of the Gung-Ho-Guns to fight Vash. Millions Knives locked him in a cell to train his body for twenty years in order to gain the necessary skill and power to face Vash.

He wears a powered battle suit and carries two high-powered chain guns on his arms. These guns fire extremely fast due to the pressure chambers located on his back and have tremendous stopping power, enough to tear through entire buildings. He also carries a wide variety of weapons in a big cloth rucksack, including an enormous minigun, powerful enough to punch through a bank vault.

Monev was sent by Legato to attack Vash, leading to a destructive brawl throughout a city, leaving many dead and shooting off Vash's cybernetic arm. He is eventually defeated by Vash, who nearly breaks his oath to never kill out of rage for all the deaths caused by Monev. Vash regains himself and spares Monev, and Monev surrenders his coin and leaves. His murdered and crucified body is later displayed by the next Gung-ho Gun, E.G. Mine, when Mine challenges Vash.

His life is spared in the anime, but is then killed by E.G. Mine along with Dominique the Cyclops due to his failure.

In Trigun Stampede

Monev's appearance is reminiscent of Venom (even more so in the manga), from the Spider-Man series, especially in contrast to Vash's red coat. Yasuhiro Nightow is known to be a fan of Spider-Man and McFarlane related products.
