I don't find the dash to be really needed
..apparently, you didn't find the
comma apostrophe to be needed either.
And I figure if K.A. Applegate went to the trouble to put in a hyphen every time she spelled the word "Hork-Bajir" than probably it's supposed to be there. Considering it's her word, I figure she gets to decide how it's spelled, and well, that's how it's always spelled anytime it's seen.
But uh, to contribute to the conversation....
Alien: .....y'all might think me crazy, but I might actually pick a Goa'uld from Stargate. Snakes over slugs any day.
Earth: Kodiak Bear. Duh? I mean, really, what else could I get away with putting here.
Time Matrix: Heck, I'd probably go with a velociraptor or whatever it was *supposed* to be. Y'know, the five-ish foot tall deadly ones. Don't care for the name, I just want the claws.
Ocean: I think that Tiger Shark is a must. 'course, I like Saltie's better, but a shark is a smarter choice, I think.
