In one mirror universe variation Kruge took the unusual step of helping the Terran Rebellion defeat the Klingon-Cardassian Alliance, in order to restore the honor of David Marcus. Marcus had once helped the Klingons resist enslavement by the Terran Empire and was considered a traitor by his people, a view Kruge did not share.
Kruge helped delay the Alliance fleet long enough to enable Smiley and the other rebels to get the Defiant operational. This came at the cost of his own life, and he vowed to be Marcus's cha'DIch when he got to the gates of Sto-vo-kor. ("A Debt of Honor")
