Dr. Phlox

22nd century genocidal madman from a race nobody ever heard of. Worse than Neelix, yeah. I said it. His entire stupid race was (thankfully) wiped out before 2254. If the Romulans did it during the war, then I say good for them. I hate the Denobulans. 
Enterprise would have been no less than 20% more watchable if he was not on it. Seriously, did Phlox actually have fans?
