Monev the Gale

Monev the Gale is the first Gung-Ho Gun to fight Vash. Knives locks him in a cell to train his body for twenty years in order to gain the skill and power required to kill 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. (Owing to Hirahano's love of MacFarlane related products, as well as the characters name and appearance, he is more than likely a reference to Venom.) from wikipedia
