1) Mister Terrific

Mister Terrific became an instant favourite among Superman audiences. His incredible brilliance impressed the fans throughout the movie, as he solved complicated issues using his brain instead of brawn. He employed advanced technology instead of just superpowers, making him stand out among the Justice Gang members.

Peacemaker can potentially benefit from Mister Terrific's extraordinary skills and knowledge. The series often features intricate plots and complex anti-heroes, and Mister Terrific's evolved mind can help solve major challenges. He can provide technical support to the team, and his serious nature will perfectly clash with the titular character's dark humor.

This may establish natural comedic opportunities for the screenwriters to explore. The interaction between him and Peacemaker can add to the entertainment while the plot progresses.

Lois Lane brings her seasoned investigative skills to any story she makes a cameo in. Her journalistic background makes her a valuable addition to any upcoming plots in the series. She can uncover threatening secrets that heroes often miss. This unique potential will help Peacemaker's narrative in the second season more effectively.

The show usually deals with complicated government conspiracies and cover-ups, and Lois Lane excels at exposing such detailed plots, as seen in Superman. Additionally, her exposés may reveal significant information about villains, adding credibility to the series. Lois represents raw journalism, and her potential direct involvement connects street-level adventures to more significant world events happening in the storyline.

Lois can also provide crucial moral guidance when required, especially when Peacemaker sometimes makes questionable choices when performing tasks at hand. This can lead to more intricate character arc moments for the audience.

3) Lex Luthor

Lex Luthor remains one of DC's most intelligent and dangerous villains. His recent loss in Superman does not imply his end in the story, as this character always finds clever ways to come back stronger.

Peacemaker can effectively show his next strategic moves against the heroes. The series can visit Lex Luthor in his strict security prison, which would display his continued impact despite being chained down. Even if imprisoned, he may effectively manipulate the events happening outside.

He can potentially hire dangerous lackeys to target the team, adding high stakes. Lex's appearance will elevate the show's overall importance significantly, as fighting Superman's main villain will make Peacemaker more engaging to fans.

Such appearances display that the John Cena-led character faces truly significant threats, too, as Lex's superior brilliance creates entirely refreshing challenge types for heroes.

4) Jimmy Olsen

Jimmy Olsen surprised many fans with his recent Superman performance. He helped defeat Lex Luthor's complicated plans successfully, all without any superpower. Just his journalistic grit. This demonstrates that he can deal with triggering and sensitive situations when required.

Peacemaker can effectively utilize Jimmy Olsen as a witness, and he may document the team's missions for The Daily Planet. This creates new opportunities for both serious drama and humor. Jimmy's reactions to Peacemaker's extreme strategies are guaranteed to entertain the fans.

The character can provide a valuable out-of-the-ordinary perspective on different circumstances. He comes from the human world, and his viewpoints help the viewers comprehend complicated superhero conflicts effectively.

Jimmy's presence will strengthen crucial media connections throughout the world, and The Daily Planet will become more integral to the DC Universe. This aids in building the shared world that blends all existing and upcoming DC Universe projects.

The Engineer managed to survive an extreme battle with Superman in the film. This leaves her completely accessible for future appearances in any upcoming projects. Her shapeshifting powers create exciting and unique fight sequences, as she can easily adapt to any threatening situation quickly.

The show requires more quality upcoming villains for the second season, and The Engineer can fill this crucial role effectively with her potential. Her powers match the show's extreme action style, and she can create different challenges each time she shows up.

The character's technology background fits Peacemaker's themes very well, as it often deals with advanced artillery and risky gadgets. The Engineers' abilities organically complement these elements in the narrative.

The drive behind her character's involvement can be that her survival from Superman motivates her to seek revenge. She may go on to seek vengeance against all heroes now, including Peacemaker and his entire unit.
