Just to set things straight one and for all. All things being equal, a vampire could beat a werewolf in a fight with little issue. Vampires can turn into bats, mist, wolves, and who knows what else. They can climb walls and move fast. Werewolves can only turn into wolves. If you go in for this business of werewolves turning into giant jacked-up bipedal killing machines with opposable thumbs, you’ve fallen prey to the hype. Werewolves turn into wolves and that’s it, and only at the full moon.
Vampires could also beat unicorns. Anyone with a decent weapon could beat a unicorn — that horn is for ornamental purposes only. About the only thing unicorns are good for is appearing to virgins.
A werewolf, on the other hand, might have some trouble besting a unicorn. (Thanks to Sarah for the link. She knows me all too well.) Pit a wolf against a horse sometime — it would be roughly similar to that.
