Vorik

Vorik was a Vulcan male who served as an engineer in Starfleet in the late 24th century. Most notably, Vorik served as a junior engineer aboard the USS Voyager during the seven years that the ship was lost in the Delta Quadrant. Following the ship's return to the Alpha Quadrant, Vorik was made chief engineer.

Early life
Vorik, the son of T'Sara and Tybik, was born along with his twin brother, Taurik, in the city of Raal on Vulcan in 2350. 

As a child, Vorik spent several summers exploring the Osana caverns on Vulcan, and spent some time engaged in some advanced rock climbing. Like most young Vulcans, Vorik had a young Vulcan girl, Selmar, who was chosen to be his future wife when the two came of age. (SS VOY (Letting Go))

Starfleet Academy
Vorik later entered Starfleet Academy in the late 2360s. Prior to his graduation, he served as a midshipman aboard the USS Independence (NCC-41452), during which time he introduced new dilithium crystal matrix protocols that improved the power conversion efficiency by 6%. He finally graduated in 2370 in the 6th percentile. 

In the Delta Quadrant
In 2371, Ensign Vorik was assigned to the USS Voyager as a junior engineer. Shortly after, Voyager was pulled into the Delta Quadrant by an alien being known as "the Caretaker", where the entire crew were subjected to testing, before being returned to the ship unharmed. 

Following the death of Voyager's chief engineer during the transit to the Delta Quadrant, former Maquis engineer, B'Elanna Torres, was appointed as the new chief. Over the next two years, Vorik assisted Torres on a number of separate occasions. 

In mid-2373, Vorik entered the initial stages of pon farr and with his chosen mate, Selmar, over 70,000 light years away, Vorik actively began searching for a new mate amongst Voyager's crew. He soon decided that Torres was his chosen mate, and started out by surprising her with a table for two at Neelix's luau with a lakeside view. 

By stardate 50537.2, pon farr had completely consumed Vorik and he openly declared the koon-ut-so'lik, the desire to mate, with Torres. During a brief physical contact between them, Vorik accidentally initiated the Vulcan telepathic mating bond, which caused Torres to undergo the same neurological imbalance that Vorik was undergoing. Vorik's pon farr was eventually ended when he and Torres fought in the Kal-if-fee ritual. (SS VOY (Letting Go))

In 2374, Tuvok's psionic abilities were amplified greatly due to his infection by a parasite. Vorik was in engineering calculating the event horizon of the singularity which remained after Voyager attempted to destroy a white dwarf star, when Tuvok was able to mentally contact him from sickbay. After collapsing in pain, Vorik was taken to sickbay were Tuvok was able to mentally connect with him. Along with experiencing a sense of peace and certainty, Vorik was able to see the solutions to how to defeat Tuvok in a game of kal-toh which they had been playing for days. Vorik then mind-melded with Tuvok and Tuvok gave him two messages to transmit - 1) he wanted to be left alone to let the parasite continue transforming them both into a new kind of symbiotic being and 2) he wanted to talk to the Monorhan Assylia. 

In 2377, Vorik helped drive aliens out of Voyager's main engineering. (SS VOY (Redux))

Chief engineer
Following Voyager's safe return to the Alpha Quadrant in late 2377, Starfleet Command made special allowances for the crew in promoting all Starfleet officers two steps in rank if they remained in the service, thus Vorik was promoted two steps up to a full lieutenant. Following, Torres departure from the ship, Vorik was also appointed as chief engineer, under the command of newly promoted Captain Chakotay. 

Vorik proudly served as the chief engineer throughout the incident with the Klingons, the "Plague of the Gods," and the rescue of Miral Paris and Torres. However, the lieutenant requested an assignment change to the USS Hawking (Nebula class) for Project Full Circle and the fleet returning to the Delta Quadrant in 2381. 

Alternate universes
In one alternate universe, Vorik was killed during an attack on Voyager by Species 8472.
