David Marcus (mirror)

Mirror Universe counterpart to Kirk’s son through Dr. Carol Marcus. The mirror version originally appeared in a licensed work in DC Comics, where he led a resistance to overthrow the Terran Empire. A slightly different version appeared in A Debt of Honor and used the resistance to carry on Spock’s vision of reform after Spock was overthrown by the Imperial Starfleet. It wasn’t the same person because it wasn’t the same quantum reality. Spock was a latecomer to the resistance in the DC Comics story, and the Klingon Empire was intact there.

In Debt of Honor Marcus’s efforts to overthrow the Empire were unfortunately too successful, as he didn’t count on Cardassia’s involvement. With the help of Cardassian warships and Ferengi dilithium shipments the Klingons not only overthrew their Terran conquerors but were able to turn the tables around and conquer Earth. Unable to live with what he’d helped bring about, Marcus committed suicide. Kruge (mirror) helps Smiley defeat the Alliance in order to fight a battle in Marcus’s name, hoping to win Marcus a place in Sto-vo-kor.
