What are your favorite aliens?

this comment was in another thread and I thought it would make a good discussion.<br /><br />[quote=Karxan]B5 was a favorite of mine for a long
time. I see it as a different twist on Star Trek, Star Wars type themes.
I think that Firefly has more elements of Star Frontiers than other
sci-fi shows or games. It has the same frontier feel, and at the same
time a &quot;civilized&quot; society. It just doesn't have any of our favorite
alien characters in it.[/quote]
