Although the Blue, Violet and Indigo rings find wielders in Pavel Chekov, Nyota Uhura and Leonard McCoy, the Yellow, Red, and Orange rings choose Klingon general Chang, a Gorn leader and a Romulan councillor as their wielders. While other members of the other Corps survive, McCoy's ring is apparently the only Indigo ring to make it into the new universe, as no other members of the Indigo Tribe are witnessed in the storyline. In the final confrontation with Nekron, McCoy transfers his ring to Spock on Captain Kirk's request, Kirk realising that
