Season 2 of “Peacemaker” premiered on Aug. 21, 2025, with eight weekly episodes releasing on Thursdays. We see Chris Smith (Peacemaker), played by John Cena, endure an emotional self-identity journey and set the stage for what’s next in the DC Universe (DCU). Personally, I adored the more sentimental leaning season, but some audiences felt it left more to be desired.
