Mark Hanford is the former CEO of Hanford Technologies.
Following the Black Zero Event, during which Kryptonians attempted to invade Earth, Hanford's company's building was destroyed. Eight pieces of Krpytonian technology were found within, but three of these were sold on the darknet on behalf of Mr. Hanford.
Some months later, Lois Lane came to question Hanford on the missing pieces of technology, having found proof of the sales on the darknet. He promptly threatened to kill her at gunpoint, confessing to the crimes, before she was able to knock him out, writing an article that would eventually prosecute him, losing his company to LexCorp.
