Weird Harold

Weird Harold was a vampire who lived on Earth from sometime before the 1900s to 1997. At some point prior to 1906 he buried himself underground in San Francisco in order to enter a healing trance, however when he awoke he found himself trapped as a building had been built on top of him. Over the intervening time he went mad through hunger, he was only able to escape in 1906 when an earthquake rocked San Francisco. When Samantha Jones and the Doctor were in San Francisco in 1997 he attacked Sam, feeding on her and practically chewing into her neck. Samantha Jones later killed Harold with a syringe of vampire repellent. (EDA: Vampire Science)
