Chekov's History
Pavel Andreievich Chekov was a 23rd century Human Federation Starfleet officer. As a cadet, this whiz kid was assigned as a navigator to the USS Enterprise in 2258, at the age of seventeen where he was involved in the defeat and death of Nero, a Romulan bent on the obliteration of the entire United Federation of Planets.
In 2258, Chekov was the navigator assigned to the Enterprise during her impromptu maiden voyage – an emergency mission to protect the planet Vulcan from attack by the time traveling war criminal, Nero.
Departing Earth's Starbase 1, Captain Christopher Pike addressed Chekov as "Russian whiz kid", ordering the ensign to use the ship wide comm to brief the Enterprise crew on the task at hand. As the Enterprise confronted Nero, Chekov used his superior mathematical skills to calculate the coordinates for beaming faster than the computer – allowing him to personally transport James T. Kirk and Hikaru Sulu back aboard the Enterprise before they fell into the singularity created on Vulcan by Nero.
Remaining in the transporter room, Chekov also transported Spock, Sarek and the surviving members of the Vulcan High Council from the surface of Vulcan. He was, however, unable to save Spock's mother, Amanda Grayson, before she fell to her death from a rock ledge that gave way shortly before transport.
After the destruction of Vulcan, Chekov devised a way to beam Kirk and Commander Spock to the Narada, without Nero knowing the Enterprise was in proximity to his ship. Chekov's plan required the Enterprise to drop out of warp near Titan, one of Saturn's moons. The radiation from the rings obscured the ship from the Romulans' sensors, allowing Kirk and Spock to successfully beam over undetected. Chekov's plan was ultimately instrumental in saving Earth.
After the defeat of Nero, Chekov served again as navigator under newly promoted Captain James T. Kirk and left with the crew to explore space.
One year later, Chekov was still serving in his role as navigator when the Enterprise was ordered to monitor the inhabitants of Nibiru. He offered a suggestion to Kirk on beaming Spock back from inside a volcano, as the planet's magnetic field prevented them from using the transporter. Chekov believed that if they had a direct line of sight, they could retrieve him. Chekov's suggestion was immediately shot down by Montgomery Scott, who reminded him the Enterprise would have to be near an active volcano. Kirk ended up following Chekov's suggestion, which resulted in a violation of the Prime Directive by exposing the Enterprise to the primitive Nibirans and also put the entire crew in danger.
Shortly after the Nibiru mission, Chekov was temporarily promoted to chief engineering officer after the departure of Montgomery Scott. Upon learning of his promotion, Chekov expressed apprehension about donning a red shirt.
Before the Enterprise could reach its destination of Qo'noS, Chekov discovered a coolant leak in the warp core and was forced to drop the ship out of warp manually. Assured by Kirk that the coolant leak was likely the result of sabotage, Chekov succeeded in the repairing the warp drive, allowing the Enterprise to avoid an initial attack by Section 31's USS Vengeance. The Vengeance, however, was able to catch up to the Enterprise and quickly crippled the ship, sending it into Earth's gravitational pull.
Catching a dangling Kirk and Scott before they plummeted to their deaths aboard the foundering Enterprise, Chekov reestablished the ship's power systems before it crashed into the surface, then retook his post on the bridge to aid in the hunt for and eventual capture of John Harrison.
Almost a year later, Chekov attended a memorial service for those who died and resumed his role as navigator on the repaired Enterprise when it embarked on the first five-year mission.
In 2263, halfway through its five-year mission, the Enterprise docked for resupply at the Federation Starbase Yorktown. After receiving a mission to escort Kalara through the Necro Cloud in an attempt to find her crew, the ship was attacked by Krall's forces. In the midst of the battle, Chekov remained on the bridge helping the ship stay afloat as Captain Kirk hid an artifact known as the Abronath from the attackers and executed a saucer separation, so the saucer section could safely land on the surface of nearby planet Altamid. Chekov, along with Kirk, Kalara and Sulu, escaped from the ship in their Kelvin pods to the surface of Altamid.
On the planet's surface, Chekov landed in the same location as Kirk and Kalara. Given Chekov could not get any transmissions on his communicator, they decided to return to the crashed saucer to locate the stranded crewmembers. In the meantime, Chekov was ordered by Kirk to investigate on Kalara as he suspected of her intentions. He was proven right as Chekov traced her communications back to Krall, proving she had been working for him all along. As Kalara pointed a phaser to Kirk demanding an artifact he hid on the saucer, Chekov appeared behind her with a gun of her own. Krall's troops attacked, but Kirk and Chekov escaped by activating the Enterprise thrusters, causing an explosion which in turn killed Kalara and thrust them through the air as they made their getaway.
The next morning, Kirk and Chekov walked into one of multiple traps prepared by Jaylah, a scavenger who was living on the planet, but they were freed after Scotty told her they were friends of his. Jaylah revealed she had made the wreckage of a 22nd century Federation starship – the USS Franklin – her home and Chekov helped Scotty use the scanners to locate Spock and McCoy, who were beamed onboard. Using Chekov's trace from Kalara's communication and pinpointing it with a Vulcan amulet Spock had given Uhura, Kirk's team was able to learn the exact location of their former shipmates and formulate a plan to not only rescue them but also stop Krall before he attacked Yorktown.
Kirk wanted Chekov to be part of the extraction team, but Spock convinced the captain that the Ensign was better off helping Scotty fix the Franklin, to make sure the transporters could rescue the crew and also that the ship could fly again. Once all the crew was beamed aboard, Chekov seated at the helm with Sulu, who proceeded with some difficulty to fly the ship from the Altamid surface to a crash landing in Yorktown.
Following the defeat of Krall, Chekov and the crew of the late-USS Enterprise gathered in Yorktown to celebrate the birthday of Captain Kirk. He was seen flirting with an alien woman named Natalia, claiming that Scotch whisky had been invented by "a little old lady from Russia."
