Carol Marcus (Kelvin timeline)

Carol Marcus was a Starfleet science officer who specialized in weapons technology. She was also the daughter of Admiral.

In 2259, Marcus made her way onto the USS Enterprise (NCC-1701) (alternate reality) because she was tracking a secret batch of photon torpedoes that she knew her father had developed. While boarding the Enterprise, she lied about her orders, claiming her father had stationed her aboard the ship, when really she had no orders to be on the ship.

Eventaully, discovered that Marcus had lied, but he failed to tell Captain  until later on, when  convinced Kirk to open the torpedoes. Kirk assigned Marcus and Doctor to open a torpedo on a planetoid away from the Enterprise. Marcus and McCoy discovered that Khan had his fellow Augments inside of the photon torpedoes.

Later, Marcus tried to convince her father not to destroy the Enterprise with the USS Vengeance (alternate reality), but she was unsuccessful and her father merely beamed her onto the Vengeance. When she met her father, Marcus slapped her father and told him she was embarrassed by him because he had worked with Khan. When Kirk and Khan boarded the ship, Marcus witnessed Khan kill her father by crushing his skull and had her leg broken.

In 2260, Marcus was assigned to the Enterprise for a five year mission of exploration.
