"Extraordinary. The power he possesses, it's like the—it's like the Gods of old. It's like Mercury on Earth. Can you imagine if you could control his power? If you could—if you could harness it? You could change what it means to be human. The man in a red mask is the key, and I'm gonna get him."
—Simon Stagg to Dr. "Harrison Wells" about The Flash[src]

Simon Stagg (died October 2014) was the corrupt CEO of Stagg Industries. Stagg was fascinated by "the man in the red mask" and the potential implications for humanity, which eventually led to his death at the hands of Dr. "Harrison Wells"./Eobard Thawne the reverse flash


Simon graduated from Central City University in his youth. He was recognized by the university, which later led to Stagg becoming the regents' choice for man of the year due to his work on organ transplants.[1]

Attack by Danton Black[]

Simon Stagg, Man of the Year

Simon being named Man of the Year.

Simon was being honored at Stagg Industries for his work in organ transference, being named the man of the year by Central City University. He thanked everyone and began to leave, refusing to give Iris West a quote for an article. A squad of men stormed the event with guns, looking for Simon, but he'd already left. Sometime later, detectives Joe West and Eddie Thawne came to Stagg, asking about Danton Black as a potential suspect though he claimed that Black was merely a biogeneticist and not a killer.

As Simon farewelled the detectives, the group of men appeared again which, unbeknownst to Stagg, were all "clones" of Multiplex. He was rushed off by Eddie, though Joe was shown the true nature of Multiplex shortly after. Following the encounter, Joe urged reconsidering protective custody yet Stagg reassured that he'd upped his security. He then greeted Harrison Wells by sarcastically suggesting not to get up for him, and returned to Stagg Industries. Later that night he finally came face to face with Danton. Before he could be shot, Barry Allen (as the Streak) sped through, grabbed Stagg and told him to stay in his office. Barry ultimately beat Black who chose to die.

Simon sat in his office through the night, when he was visited by Wells. They began discussing the speedster similar to "Mercury on Earth". Stagg suggested that there were possible major implications if they could find and harness the speedster's power. Wells, wishing to protect the man who would come to be known as "The Flash", stood up from the wheelchair and stabbed Stagg, killing him.[1]


Following Stagg's reported disappearance, rumors spread that he'd become a recluse after Black's murder attempt.

Mason Bridge's unpublished article

Mason's unpublished article implicating Wells in Stagg's disappearance.

Reporter Mason Bridge's investigation into Wells led to Mason discovering Wells's presence at Stagg Industries on the night of Stagg's disappearance, causing Mason to suspect Wells was involved. Mason discussed this with Iris who in turn shared this suspicion with Barry. Barry would also confront Mason about Wells's role in Stagg's disappearance, but Mason refused to share the details. Unfortunately, this indirectly led to Wells discovering Mason's investigation into Stagg, resulting in Mason's murder and evidence being destroyed[2] as well as Barry finally realizing Wells's true nature which sparked an investigation that eventually lead to Team Flash discovering Wells's true motives and identity as Eobard Thawne/Reverse-Flash.[3]


Simon had built a careful reputation and façade as a philanthropist, but he was actually driven by ambition and greed in almost equal measure; he was arrogant, selfish, power-hungry and immoral. Simon was known to steal other individuals' research or take credit for their work to further his own career, being sued at least 20 times for this. Simon planned to exploit Barry Allen's powers, and proudly admitted this to Eobard Thawne (under the guise of Harrison Wells), a reckless action which cost him his life at the hands of the latter.
