Wanted to post the quiz, since I got my favourite race!
HelloQuizzy.com: The Which Star Trek Species Would You Be? Test
The sly and scientific. Congrats, my second-favourite species!
You are a Romulan. One of the most cunning species, you know how to tell a good lie. When faced with a problem, you tend to use prior knowledge and instinct to help you. You can have wild mood swings, and are easily offended. When offended, you tend to be vengeful and plot a way to obliterate your offender. You cannot stand for incompetence, and beleive that only the strong should survive. You are not exactly violent, but neither are you peaceful. You will only act in peace if it benefits you. Devious and cunning, you make a very good spy.
Well-known Romulans include Sela from TNG; and Donatra of ST: Nemesis.
