Frederico

Frederico was a business assistant of Jacobi Sparochi.

Physical appearance
As a young man Frederico was a healthy Caucasian man with gray hair tied back in a ponytail.

After becoming corrupted by the pearl's evil, he turned into a horrible monster with slimy purple skin and tentacles.

History
Frederico helped aid Sporachi in harvesting deep water pearls. One day, one of their divers discovered a black pearl, which held the essence of evil within it. Frederico was driven insane by the power the black pearl possessed and used its energy to gain an immortal soul while also cursing his business partner Jacobi with eternal life without eternal youth.

Two and a half centuries later, Sporachi had become a gondolier, whereas Frederico had taken over the Sporachi mansion as an evil, hideous monster.

The Quest team along with two French scientists, Professors Eric and Francois, attempt to destroy the ghostly entity with the French equipment built by the scientists. Unfortunately, Frederico gained more power from the machine and further displayed it by absorbing Hadji Singh and Race Bannon and brutally killing Francois and Eric by sealing them in a closet where the ceiling descended down upon them, crushing them to death.
