Pavel Chekov

Pavel Chekov was a Starfleet officer who served as navigator aboard the ISS Enterprise, first officer aboard the ISS Reliant, and security chief and later captain of the ISS Enterprise-A.

During the crossover incident in 2268, Chekov attempted to assassinate the Kirk double. When the assassination failed, Chekov was tortured in the agony booth. Although his crime was punishable by death, the Kirk double ordered him confined to quarters. Later, Chekov successfully argued he had attacked an imposter, and therefore his action was not a crime. Kirk was amused by the incident, and chose not to execute Chekov. The incident proved a lesson to the young Chekov, who would not be so brash in the future.

By the 2280s, Chekov served as first officer and tactical officer aboard the ISS Reliant. On an expedition to Ceti Alpha V, Captain Terrell and much of the crew became infected with Ceti eels. As the afflicted became more aggressive and insane, Chekov was forced to assume command and liquidate a large portion of the crew, including the Captain. As a reward for his actions, Chekov was promoted to captain and put in command of the ISS Enterprise-A.

He would command the Enterprise until 2293, when a conspiracy to overthrow the Emperor with Captain Sulu of the Excelsior was uncovered. Sulu successfully hid his role in the conspiracy, and accepted orders to destroy the Enterprise. The Enterprise was destroyed with all hands lost.
