The Vampire of Paris was the name given to the creature that terrified the Montmartre area of Paris in 1895.
It was not a vampire in the true sence, but a creature that gathered energy. Much of that energy coming from Time. Its main function was to seek and locate alternative sources of power for its ship that fell through the same hole in the vortex as Varlos did when he first hid on Earth.
Varlos had witnessed the Vampires first attack, on Baron De Guerre, and in order to cover up his own involvement had assumed the identiy of De Gaulle in the hope of hunting the creature down before it drew attention.
The creature however continued to gather energy beyond its full capacity. With the crew dead on arrival the creature was following its sole purpose of gathering even more energy. Without the means to discharge its energy the creature became unstable. It was eventually returned to the vortex and its pain, lonliness and the madness it has known for so long was brought to an end.
