what is the difference between vulcans and romulans
Romulan The Romulans also act as a counterpoint to the logical Vulcan race, whom they resemble and with whom they share a common ancestry. As such, the Romulans are characterized as passionate, cunning and opportunistic â€” in every way the opposite of the logical and "cold" Vulcans. The Romulans are the dominant race of the Romulan Star Empire. Although Star Trek Star Charts place the Romulan Empire's territory in the Beta Quadrant of the galaxy, in Star Trek: Deep Space Nine they are referred to as an Alpha Quadrant power.
Pear-shaped The comparison is more or less literal when the term is applied to people, where it means narrow at the shoulders and wide at the hips, a use that goes back to at least 1815, and one that can have either positive connotations (as in Venus figurines) or negative, depending upon the context.
