The season finale of *Peacemaker* surprised viewers with a reference to *Super Mario Bros.*, officially adding a character from that video game universe into the DC Universe. While the episode had a lot going on – including the investigation of the Quantum Unfolding Chamber, Peacemaker’s imprisonment, and the 11th Street Kids joining a new group – the show still found room for enjoyable Easter eggs and cameos. Despite setting up major storylines for the future, like the introduction of a planet called Salvation, the John Cena-led series delivered a fun and memorable finale.
The finale of *Peacemaker* Season 2 featured a performance by the band Foxy Shazam of their song “Oh Lord,” playing during a heartwarming montage of the 11th Street Kids becoming the new Checkmate team. Beyond that exciting musical moment, the episode also confirmed that a video game character is part of the DC Universe.

In the eighth episode of *Peacemaker* Season 2, titled “Full Nelson,” Adrian Chase is shown playing *Princess Peach: Showtime!* on his Nintendo Switch at the 20:30 mark. This confirms that the character of Princess Peach is officially part of the DC Universe’s established storyline.
Adrian brought up the game while Leota Adebayo was checking to see if he was okay, following Christopher Smith’s imprisonment.
I’m really getting into Princess Peach: Showtime!, but it’s challenging, and it’s not simply because the main character is female.
Princess Peach is the ruler of the Mushroom Kingdom and a key character in the *Super Mario* series, known for her connection with Mario. She was created by Shigeru Miyamoto and has been featured in most of the *Super Mario* games.

Good-Feel created *Princess Peach: Showtime!*, the first action-adventure game starring Princess Peach as the hero since *Super Princess Peach* in 2005.

A cool detail some viewers might miss in *Peacemaker* is the confirmation that Spider-Man is part of the DC Universe. This happens in Season 2, Episode 6, when Vigilante encounters someone who looks exactly like Spider-Man from an alternate Earth called Earth-X.
The season finale of James Gunn’s *Peacemaker* hints at the future of the DC Universe. It introduces Salvation, a new planet or dimension, and Checkmate, a previously unseen organization. The episode first aired on HBO Max on October 9, 2025.
Will the DCU Continue With Fun References to Other Franchises?

James Gunn, co-CEO of DC Studios, is working hard to launch the DCU successfully, and he’s also enjoying adding playful references and real bands to the new universe.
James Gunn is famous for his movies’ funny, lighthearted tone and strong sense of teamwork. He consistently manages to seamlessly integrate special appearances and inside jokes into the main storyline.
The surprise appearance of Nintendo references, like the nod to Princess Peach, in the Peacemaker Season 2 finale was a delightful moment that genuinely excited longtime fans.
The mentions of Princess Peach and Spider-Man suggest DCU projects might include more playful references and hidden details going forward. This could even lead to a potential crossover between Marvel and DC universes in the future, something James Gunn has hinted isn’t impossible.
