If you happen to be a DC fan, then chances are you have been teeming with excitement for Peacemaker Season 2 just like kids waiting for Halloween. It feels like we have had to go through the longest time without having to get this mad eclectic hero James Gunn story back on HBO Max, but now it’s back, spreading the laughter and empathy of John Cena’s bizarre but brilliant annihilation.
The major thing that gets me pumped for this time, besides the return of Peacemaker himself, is the crazy mixture of new and familiar faces that are having a profoundly influential impact on the DCU. The first that comes to mind when we think about the 10 greatest characters that made the new season a must-view, counting from 10 to 1, are: presenting them in a countdown from 10 to 1, we have the 10 greatest characters that made Season 2 a must-view, DCU.
10. Rick Flag Sr.
Frank Grillo plays Rick Flag Sr., a tough-talking A.R.G.U.S. commander with a chip on his shoulder. The death of his son in The Suicide Squad sets him on a collision course with Peacemaker. His no-nonsense command line and enraged backstory bring some serious heat to the squad dynamic.
9. Maxwell Lord
Sean Gunn is the astute billionaire who operates behind the scenes. As a financier of the Justice Gang, Lord decides whether Peacemaker’s actions are heroic or irresponsible. He holds himself responsible for all that he does and believes that he has an ulterior motive.
8. Hawkgirl
Isabela Merced soars as Hawkgirl, headlining the rebooted Justice Gang flashbacks. She brings a signal towards Gunn’s broader DC ambitions—and fans are already guessing the crossovers she’ll bring.
7. Guy Gardner (Green Lantern)
Nathan Fillion’s Guy Gardner is the wisecracking and irreverent Green Lantern. His humorous back-and-forth with Peacemaker reads so Gunn. And the debut teases bigger Lantern stories to come.
6. Mr. Terrific
Edi Gathegi’s brilliant hero makes a shadowy entrance during the flashback sequence. While his role is small for now, Mr. Terrific’s tactical mind and advanced tech practically guarantee he’ll become a major player as the DCU expands.
5. Supergirl
Milly Alcock initially appears as Supergirl, appearing after Superman and Mr. Terrific in the retconned flashback. She’s back to mark that Gunn is now technically cross-breeding the Kryptonian line in his universe, which will lead to some interesting things.
4. Superman
David Corenswet dons the cape as the DCU’s Superman in place of Cavill in the revised flashback. It’s a welcome and brief cameo, solidly grounding Peacemaker in Gunn’s larger plans for the franchise.
3. Judomaster
Nhut Le’s hotheaded Judomaster returns, this time battling alongside Economos rather than against him. His martial arts ability, sharp tongue, and ever-changing allegiances leave viewers speculating—and chuckling—each time he appears on-screen.
2. Vigilante
Freddie Stroma steals the scene again as Vigilante, the self-destructive, dark humor best friend Peacemaker can’t seem to avoid, but definitely doesn’t need. His ridiculously over-the-top loyalty and adorably dodgy sense of humor make every scene with him worth watching.
1. Peacemaker (Christopher Smith)
John Cena’s helmeted antihero is still the focal point of the show. He’s confronted with even wackier challenges this season—battling alternate versions of himself, his dad, and so on. His arc at its base is still one of redemption, coping with trauma, and redefining “peace”—served up with Gunn’s ideal blend of zaniness, brutality, and surprise heart.
Season 2 confirms that Peacemaker is not another superhero series—it’s a crazy, passionate, and laugh-out-loud zany trip through the most bizarre and wacky corners of the DCU. With this cast of characters, I’m expecting action, comedy, and some surprises along the way that’ll have you hooked on your screen.
