Nevada Johnson is a troll explorer who appeared in Mirror, Mirror. In his possession, he had a magic mirror capable of switching Spyro and Kaos back to their normal bodies when they were actually switched by the Mirror of Mind Control.
Nevada however refused to give up the priceless mirror without a fight, forcing Spyro and Kaos to fight the troll explorer through the tunnels. When Kaos (in Spyro's body) managed to grab Nevada and carry him airborne, the dragon accidentally crashes into a pipe, dropping both the mirror and Nevada. While the mirror was caught by Glumshanks, Nevada was knocked out from the fall.
