William F. "Buffalo Bill" Cody

William F. "Buffalo Bill" Cody (1846-1917) was one of many prominent figures on the 1893 expedition to Mars. In Martian Dreams, Bill, along with Calamity Jane, ran a trading post, at which Bill was in charge of ammunition and other "trail goods."

In addition to trading in goods, Bill mentioned to the Avatar that their primary Oxium supplier, a man named Cooter McGee, had gone missing. Bill and Jane suspected raiders from Argyre were involved in Cooter's disappearance, and sent the Avatar off to investigate -- supplying the hero's group with some Oxium and purple berries to assist in the endeavor.
