A different look at the Comet. When he first appeared in Pep Comics in 1940 the intro description read: “John Dickering, a young scientist, discovers a gas that is fifty times lighter than hydrogen. He also discovers that by injecting small doses of the gas into his bloodstream, his body becomes light enough to make great leaps through the air. After many such injections, the gas accumulates in the eyes and throws off two powerful beams.”
Sounds to me like he became a junkie. A deadly one at that. I thought it would be interesting to show the Comet as a man who does a bad thing (shoots up dangerous chemicals) to accomplish good deeds.
