Cowboy

The cowboy was one of Natla's henchmen.

After Kold grabs Lara, the cowboy takes Lara's pistols from their holsters. Later, in Natla's Mines, the cowboy is using Lara's (or Pierre's) magnums to kill her. Lara wins the battle and takes back the magnums.

Trivia

 * The cowboy doesn't return for Tomb Raider Anniversary. He is replaced by Larson which means that Larson's death now takes place in Natla's Mines.
