Dr. Phineus Phibes

Dr. Phileus Phibes is a scientist obsessed with becoming immortal.

Personality
As time progressed he became more and more high strung from the combination of his henchmen's idiocy and the repeated interference of the dog (Scooby-Doo) and hippie boy (Shaggy).

Histroy
In his youth, Phibes conducted a highly dangerous experiment with electricity in order to achieve his dream, which cost him his left hand (he wears a prosthetic that seems to function as a high-tech Swiss Army knife) and made him a living lightning rod -- hence, he seldom ventures outdoors, because his condition will quickly cause storm clouds to gather regardless of the weather.
