The dossier
The first metahuman threat
Clyde Mardon was already a violent criminal before the explosion at S.T.A.R. Labs. When granted the power to control fog, wind, and lightning, his arrogance completely consumes him, viewing himself as a literal god.
He serves as the crucial first test for Barry Allen. Clyde’s sheer destructive capability forces The Flash to realize that his super speed must be used not just to run, but to actively protect Central City from living natural disasters.
His brief but explosive arc establishes the high stakes of the series. Mardon is a terrifying showcase of what happens when incredible power is handed to a man with absolutely zero moral restraint.
