A Vulcan aide who accompanies Sarek on a secret peace mission in 2256 and reveals himself as a logic extremist, blowing himself up in an attempt to kill the ambassador.
V'Latak appears in Lethe. He travels with Sarek aboard a small Vulcan cruiser on the way to Cancri IV, where two Klingon houses have offered to talk.
During the flight he declares that Sarek's fascination with humans, shown by his human wife, his half-human son and his human ward, is a betrayal of Vulcan purity and that the Federation is a failed experiment. He then triggers a device within his own body. Sarek raises a force field in time to survive but is left gravely hurt and adrift in a nebula.
The attack drives the rest of the episode, as Burnham reaches her foster father through the fragment of his katra she carries, and Admiral Cornwell goes to the talks in his place.
