Anton Relnic was an Ambassador for the United Planets.
He was involved in trying to negotiate a peace treaty between the United Planets and Dominators. The Legion of Super-Heroes who were assigned as security to the peace conference were treated with hostility by Relnic who did not want the Legion to interfere with the peace negotiations.
Some years later Relnic became a pawn of Universo via mind control.
