The Silver Ghost had the ability to transform objects and people into solid silver, with Shift Z ability. In game terms, this means that his practical limitations are 500 lbs. of non-living matter, with permanent duration; or up to 500 lbs. of living matter can be transformed for a maximum of 4 days, after which the material reverts back to its original state. The power can only be used once per day.

The Secret Society of Super-Villains
Raphael Van Zandt was a Nazi leader on Earth-X who had been double-crossed by Rod Reilly, a resistance fighter who posed as a Nazi sympathizer. When the war ended on Earth-X, Van Zandt traveled to Earth-1 in an undisclosed manner to track down Reilly. This interdimensional trip apparently endowed Van Zandt with his powers.
Finding no trail to follow to Reilly, Van Zandt became the Silver Ghost and began hounding the Freedom Fighters, believing they would lead him to Firebrand. When the Freedom Fighters eventually met up with Firebrand, the Silver Ghost closed in for the kill, hiring the Secret Society of Super-Villains to destroy the entire team of heroes. A face-to-face confrontation ended with both Firebrand and the Silver Ghost transformed into silver.
