James Zolomon is a minor antagonist in The CW Arrowverse series The Flash. He's portrayed by Shaine Jones.
James was a soldier on Earth-2 who was a veteran of a conflict known as "War of the Americas." He was thought to be a war hero. But in actuality, he was an abuser to his wife, Ashley Zolomon. When he returned home after being on the front lines for years, he would find his wife was in the process of leaving him with their son Hunter Zolomon. He would physically beat her in front of their son. He would go to his son, have him put on his helmet he wore during the war and said "You're gonna want to see this." He would then pull out a shotgun and murdered his wife in front of their son. He would then be sent to prison for the rest of his life. Assuming he didn't meet his end before 2019, he is assumed deceased when an antimatter wave cut a swath through Earth-2, destroying the universe, with all living being being destroyed in the process, which would have included James.
Because of his actions, his son would be put in the system and would live in foster homes. Hunter would pick up homicidal tendencies because his father's actions psychologically damaged him. He would become a serial killer, which is a rarity on Earth-2. When the particle accelerator within STAR Labs exploded, he became something much worse. He would terrorize Central City as an evil Speedster who lead Black Siren, Killer Frost, and an army of meta-humans. He would eventually be stopped by The Flash and his team from Earth-1.
