Cneb is a skull Digger, meaning he wears a cow skull over his face. He also has earth-based attacks, most of which originate from his hammer. He can hold his own against a good amount of opponents.
However, fighting is not Cneb's claim to fame. He's the only one with the knowledge to create sacred items. This includes the Alpha Blade. There are many games that his main use is to create these items. In War of the Worlds VII: Y3K, he sets up a fusion shop where two items combine into a new one. He makes many items in that shop that are required to beat the game.
The name came from a person named Ben C. However, there were too many Bens as it was, so his name got reversed to preserve individuality.
