Vanik was a Vulcan officer in the 21st and 22nd century, ranked Captain. He joined the Vulcan Space Program in 2075 and took command of the starship Ti'Mur in 2136, remaining in that position until at least 2151.
In that year, Vanik shared a meal with Jonathan Archer, T'Pol and Charles Tucker III aboard Enterprise when the two starships encountered each other during Enterprise's survey of a rogue comet. The dinner did not go well, as Vanik did not eat and barely spoke, and when he did, he used veiled insults. Frustrated, Archer finally demanded to know why the Vulcans were spying on him. When Vanik refused to give him a proper answer, Archer asked him to leave his ship.
Meanwhile, Malcolm Reed and Travis Mayweather became stranded on the comet when the ice under their shuttle collapsed, trapping them. With the Enterprise's grappler unable to retrieve the shuttle, Archer accepted assistance from Vanik, who, with the use of his vessel's tractor beam, was able to rescue the crewmembers.
