Fan Casting Sea King in Justice League

After the Crime Syndicate is stopped by the heroes, Ultraman tells their story. How their Earth was invaded by a powerful being, and Earth’s heroes (scattered, divided, outlawed, and hated; collectively named the “Crime Syndicate” by governments and law enforcement) were unable to stop it. While he tells the story, we see flashbacks of their Earth, and an improvised team of heroes storming the gates to try and take Amazo down, but ultimately failing. Sea King is on the team.
