Hybrid

Hybrids are a cross-breed of two or more different supernatural species. The term is commonly used to describe a werewolf turned into a vampire due to the fact that they were the first supernatural hybrid to be introduced in the series. However, since the werewolf-vampire hybrid's creation, there have been other cross-breed hybrids revealed in the series' universe, such as Siphoner turned witch-vampire hybrids, werewolf-witch hybrids (Mireya Mikaelson), and, in the rare case of Hope Mikaelson, Tayler Mikaelson, Odessa Parker, Leonardo Parker, and Kimberly Salvatore witch-werewolf-vampire tribrids.

Hybrids possess both the strengths and some of the weaknesses of their parent races, along with powerful attributes unique to themselves alone due to their combined heritage. For werewolf-vampire hybrids, this includes Day Walking and being able to transform into a wolf without the Full Moon's influence. For siphoner-vampire hybrids, they retain their ability to siphon magic and their own vampirism as a power source for their use in witchcraft; as they did not possess their own magic as humans, this is a skill that makes them powerful.
