Maxwell Lord

The character made his cinematic debut in the 2020 DC Extended Universe film, Wonder Woman 1984, portrayed by Pedro Pascal.

A new iteration portrayed by Sean Gunn will appear in the upcoming DC Universe (DCU) franchise, starting with the film Superman (2025).

Thus, he sparked the plans to bring the Justice League, leaderless and broken after the Crisis on Infinite Earths event, under his exclusive control.

[4] Lord's ruthlessness at this time was illustrated when he set up a disturbed would-be terrorist as a villain for the League to defeat, resulting in the man's death.

During the time that Giffen and DeMatteis were writing the Justice League, Lord is shown struggling with his conscience and developing heroic qualities, though he would remain a con-artist.

Instead, at the urging of his mother to act for the benefit of non-metahumans, he shifts his hatred for the generic "authority figures" who caused his father's death to the metahuman community.

While possessed Lord forces the JLI to battle itself, the mortally wounded Silver Sorceress manages to contain Dreamslayer, and holds him within her mind as she dies, taking him with her.

[4] Lord puts together several former JLI members, including L-Ron, Captain Atom, Blue Beetle, Booster Gold, and Fire as the "Super Buddies", advertised as "heroes the common man could call".

[9] In Brad Meltzer's Identity Crisis (2004), Lord attends Sue Dibny's funeral and speaks to Booster Gold, further denting his already dwindling faith in superheroes.

[10] Countdown to Infinite Crisis reveals that Lord is no longer a cyborg, and is a criminal mastermind who spent years running the JLI while gathering sensitive information about the world's superheroes, whom he considered a threat to the planet.

[14] In Blackest Night and Brightest Day, Maxwell Lord is revived as a Black Lantern before the Life Entity fully resurrects him.
