Pavel Chekov, son of Andrei Chekov, was born in Russia on Earth in 2245.

Around 2263, Chekov entered Starfleet Academygraduating as an ensign. Starfleet serial number 656-5827D.

Chekov's first assignment, at the age of 22, was on the USS Enterprise under command of Captain James T. Kirk. He joined the crew sometime prior to 2267.

Chekov served a standard junior officer rotation, eventually earning the post of navigator, although he was also proficient with the science officer station, often serving at the post in Spock's absence.

While investigating a humanoid that could generate and control energy, who referred to himself as Apollo, in 2267, Chekov began to spout off information on similar creatures. He was stopped by Dr. McCoy, who told him "not the whole encyclopedia, Chekov,"

Chekov, Kirk, and Uhura were captured by alien beings who used them in gladiatorial combat, which the beings wagered on. Such captured beings were known as "thralls." One of the thralls, Tamoon, who was assigned to train Chekov in gladiatorial combat, developed romantic feelings toward him, leading to many unwelcome advances.

Chekov was part of an away team that beamed aboard the starship USS Defiant, which was adrift in space. They discovered that the ship was dissolving. After beaming back to the Enterprise, Chekov attacked Spock in a fit of madness. The illness then spread throughout the ship. The dissolving of space was causing mental breakdowns in the crew. After rescuing Kirk, and escaping the Tholians, order is restored.

In 2269, Chekov would once again encounter his lost love, Irina Galliulin. Click here for their story

Later in the year, Chekov was no longer be navigator on board the Enterprise, having been replaced by Arex.

Later Career

By the early 2270s he was a lieutenant and served as the security chief and tactical officer under the command of Captain Willard Decker.

Chekov was later promoted to commander and assigned as first officer to USS Reliant under Captain Clark Terrell.

In 2285, Reliant was on a mission to find a suitable planet to conduct trials with the Genesis Device. When they explored Ceti Alpha V, Chekov and Captain Terrell encountered Khan Noonien Singh and his augments.

Also in 2285, Chekov and his shipmates Kirk, Scotty, Sulu, and McCoy stole the Enterprise from Spacedock (with Uhura's help) in an attempt to recover a regenerated Spock from the Genesis Planet. The crew then transported Spock to Vulcan, where the body would be reunited with his katra, which had been placed in McCoy. using a capture Klingon Bird of Prey which they named the Bounty

Using the slingshot effect they went back in time to 1986, to transport two Humpback whales to the 23rd century.to speak to an alien probe which was destroying the Earth as it could find no whales to talk to.

Upon returning to the 23rd century, Chekov and his shipmates faced court martial for their actions although these actions had saved the Earth. However, they were eventually cleared of all charges, and Chekov was reassigned as second officer, Navigator, and security chief on the Enterprise-A

In 2286, Chekov took command of the Enterprise-A and posed as "Captain Chekov" as a ruse to negotiate with Sybok for the hostages that the renegade Vulcan took on Nimbus III, while Kirk, Spock, Uhura, and a security team landed on the planet covertly by shuttlecraft.

In early 2293, Chekov undertook his final voyage on the Enterprise-A as part of the mission to escort the Klingon Chancellor to peace negotiations with the Federation. Chekov used his investigative science background to find forensic evidence linked to a Federation-Klingon conspiracy attempting to undermine the peace talks. After the Khitomer Conference, Chekov's last duty on the Enterprise-A was to man navigation and the helm for her decommissioning cruise.

In the latter part of 2293, Commander Chekov was a guest of honor aboard the new USS Enterprise-B under the command of John Harriman. During the maiden voyage, Captain Kirk went missing (presumably swept into space) during a hull breach caused by a part of the Nexus energy ribbon when it collided with the Enterprise-B.
