Toonopedia’s Don Markstein says of the Sorceress of Zoom, who appeared in the first 20 issues of Weird Comics, that she was a villain who later became a hero, but more of “an ambiguous hero like Sub-Mariner.” Would you trust anyone who was described as ambiguous? Not me.
The article also says the early adventures were drawn by Don Rico, and he may have created the Sorceress of Zoom. It appears the history of the feature is also ambiguous.
