Simon Stagg - Young Justice: Outsiders (2019)

The C.E.O and majority shareholder for numerous companies, Simon Stagg was an industrialist who created the Branchwater metahuman trafficking ring to ensure that Stagg Industries could publicly compete with rivals, whilst also secretly have them commit industrial espionage on his behalf.

He hired mercenaries Cheshire and Sportsmaster to procure him metahuman criminals, whilst also engaged the Mad Hatter with a proposition, paying him to create a device that would give him complete control over them. 

Nightwing believed that Stagg's participation in this scheme caused him to develop paranoia against metahumans, for fear of being subjected to the same crimes he had committed onto others. Wanting to find a way to neutralise metahuman abilities should it be necessary to do so, he discovered the existence of a Metahuman Failsafe that had been salvaged from a Reach warship and was being kept at STAR Labs Detroit for further research. Stagg contracted Cheshire to lead a team to the facility and steal it for him.

However, he was caught red-handed by Miss Martian and Superboy when the Reach device was transported to him via the Shade's ability to open shadow portals. He was arrested by the G.C.P.D after they received an anonymous tip about his companies' illegal activities, leading to his incarceration. 

Whilst reading in his prison cell late one evening, Stagg was visited by Shade, who had been freed from Tetch's mind control by Cheshire. Stagg became terrified at the sight of his former victim, trying to back away as the metahuman advanced on him.
