Esteban Lopez

Esteban Lopez was a male Human who lived in the 24th century. In the 2360s and 2370s, Lopez held the rank of lieutenant in Starfleet and was a science officer, serving aboard the USS Saratoga (NCC-31911) and later the USS LaSalle (NCC-6203). Lopez was serving aboard the Saratoga when it engaged the Borg at Wolf 359 and was among the survivors.

In 2372, Lopez was one of several survivors of the Saratoga who travelled aboard the USS Defiant (NX-74205) (I) to Utopia Planitia, where the new Saratoga was being prepared for launch. By this time, Lopez had suffered large gambling losses to the Retizians and was forced to sabotage the Defiant to allow the Retizians to take the Saratoga personnel prisoners. Lopez' betrayal was discovered by Captain Benjamin Sisko and Lopez was arrested, facing a court martial and a sentence to a penal colony for his actions.
