A humanoid race, with copper-based blood, slightly green-tinted complexion and notably pointed ears, the race responsible in a large part for the founding of the Federation. Vulcans have developed a culture dedicated to the complete mastery of logic, learning to suppress their once-violent emotions in nearly every aspect of their existence.

In ancient times, Vulcans were a war-like race, leading to their near extinction. Its ancients believed in gods, such as war, peace and death.

Vulcans can perform a synaptic pattern displacement, or the transfer of one individual's consciousness into another: in their case, the transfer of the katra.

Vulcans are typically stronger than Humans though they do not boast of this strength. Vulcan honesty is legendary, even to Ferengi. Cardassian mental disciplines may be a match for Vulcan's, although those of the other race do not employ telepathy.
