Thunder Walker, once a member of the Sotka'yuha and Toka'la warrior societies, stood somewhat tall at ten inches over five feet in height. He was built of lean muscle and his body showed scars and his hands showed callouses from bowmanship and work with the war club. When on the trail and in the wilderness, he dressed as might one of his people, though when he entered town, he favored some clothing of the white man so as to fit in more easily.

After returning to his people he discarded these trappings of the so-called civilized world gradually as he came to follow Wovoka and believe in the power of the Ghost Dance.
