The second season of James Gunn’s Peacemaker recently wrapped up its eight-episode run, earning a stellar 95% critics’ score on Rotten Tomatoes. While the much-talked-about finale, titled “Full Nelson,” delivered a shocking climax that could shape future DCU projects, it received mixed reactions from viewers.
Many fans had been expecting major cameos from David Corenswet’s Superman, Idris Elba’s Bloodsport, or Xolo Maridueña’s Blue Beetle. Instead, they were perhaps caught off guard by a story-centric, character-driven, and emotionally resonant Peacemaker Season 2 finale.
That’s not to say there weren’t any notable appearances from the Superman Universe. Nicholas Hoult’s Lex Luthor, for instance, made a crucial cameo that played a key role in the plot. However, there was another surprise cameo in the finale that many viewers completely missed. Read on to find out which one it was!

If you look closely, the DC Studios co-CEO can be spotted standing beside Nelson during Foxy Shazam’s concert scene, a subtle Easter egg that many viewers overlooked on their first watch.
