Silvermane (The Spectacular Spider-Man)

Silvermane was a rival mob boss to Tombstone and Doctor Octopus. It was revealed that Silvermane was arrested and jailed twelve years beforehand after Frederick Foswell exposed his criminal activities to the FBI. His empire fell, and his territory was taken over by Tombstone/Big Man. Silver Sable, his daughter in this continuity, had been running the remnants of his empire in his absence.
