Vampires and werewolves share some similarities but also have key differences. Both are shape-shifting creatures that change from human to animal form, with vampires transforming into bats and werewolves transforming into wolves near the full moon. However, vampires can control their transformations while werewolves cannot. Vampires are typically depicted as cold and calculating while werewolves are passionate and animal-like. The two creatures also present different threats, as vampires actively hunt humans for blood while werewolves may hurt humans unintentionally during wolf transformations induced by the full moon.
