Great Vampire

The Great Vampires were massive humanoids from Gallifreyan legend. They originate from the Dark Times.

Physical Description
The Great Vampires were colossal humanoids with grey skin and wings. Like lesser vampires, Great Vampires required blood to survive, but due to their large size they needed considerably more. Great Vampires were extremely powerful and one individual could drain a whole planet dry. They had the ability to absorb energy, such as from weapons, and were able to survive numerous minor wounds. The only way to kill one was to stab them through the heart, usually with a steel bolt. More powerful Great Vampires needed to have their heart fully destroyed in order to kill them.

War with the Time Lords
Eventually Time Lords hunted these creatures down in a long and bloody war, using bowships firing mighty bolts of steel to pierce their hearts. Though the Time Lords won, they incurred heavy casualties. Even then, the leader of the Vampires escaped into the smaller universe of E-Space. After time, the records of this war were lost and passed into legend. Rassilon wrote data about the vampires that was installed into every Type 40 time vessel. It informed that one vampire, the King Vampire, had vanished and it was a time lords solem duty to lay down his life to kill it. This war was said to have sickened time lords of violence forever.
