Gung-Ho-Guns

The Gung-Ho Guns (ガンホーガンズ|Ganhōganzu) are a group of assassins assembled by Millions Knives and lead by Legato Bluesummers to cause great pain to Vash The Stampede. Each one is human (with the exception of Gray the Ninelives, who in the manga, is a robot), but has sacrificed their humanity in order to gain power, often leaving them mutilated. Each Gung-Ho Gun has an assigned number, but not all numbers are revealed. They're used to play a "game" with Vash. He has them each carry half a coin, and gives Vash a case to hold them, telling him that something "special" will come from it. The filled coin case functions as a device to block Legato's powers.

Members
The following are the members of the Gung-Ho Guns who appear throughout the franchise; both the manga and anime. The assigned number comes from a combination of self-reported numbers by the Guns and by the order that Vash tallies his collected twelve coins. These members only appear in the manga. This is the only non-canon Gung-Ho Gun that appears in the anime.
