James Gunn’s DCU “Diamond Characters” Plan Explained: Superman, Batman, and Wonder Woman Lead the Way

James Gunn DCU diamond characters plan starts with characters, not crossover charts. When James Gunn talks about the future of the DC Universe, he does not start with a crossover chart. He starts with characters. In recent posts on Threads, the DC Studios co-chief revisited the long-term plan he and Peter Safran first pitched inside Warner Bros. Discovery, and he gave fans a clear way to understand it: some heroes are already diamonds, and others could still be cut into diamonds.

What the James Gunn DCU diamond characters plan actually means

That distinction explains why the new DCU has felt uneven to some viewers. Superman arrived first and carried the opening chapter. Batman and Wonder Woman, the other two names on Gunn’s diamond list, have not yet taken centre stage. Meanwhile, projects built around less familiar names have moved ahead of them. Gunn’s message is that this was part of the design, not a change of direction.

According to Gunn, the often-quoted eight-to-ten-year roadmap was never only a list of story beats. It was also a plan for DC as a whole, including focusing on diamond characters — Superman, Batman and Wonder Woman — plus smaller characters the studio could turn into diamonds: Krypto, John Stewart and Peacemaker. Around that core sit other principles Gunn has repeated since January 2023: filmmaker freedom, different tones and ratings, and influences from Star Wars to George R.R. Martin.

Put simply, the James Gunn DCU diamond characters are the foundation. They are the heroes audiences already know around the world, the ones who can anchor films, merchandise, animation and television without needing an introduction. Superman, Batman and Wonder Woman have carried DC for generations in comics, television and film, and Gunn is betting they can do so again — not as a nostalgic tribute act, but as the centre of a new, coherent universe.

The heroes who could become DCU diamonds next

The second group of the James Gunn DCU diamond characters plan is where the gamble lies. Krypto, the super-dog who stole scenes in Superman, connected instantly with family audiences. Peacemaker, played by John Cena, has built a loyal following across two seasons. John Stewart, one of DC’s Green Lanterns, has rarely had a proper live-action showcase until now — and that is precisely Gunn’s point.

That brings us to the other half of Gunn’s recent clarification: standalone stories versus the larger saga. Some projects, he said, are meant to stand alone in the way his Guardians of the Galaxy films largely did, even inside the Marvel Cinematic Universe. He placed Clayface in that category. Other projects belong to a larger narrative structure, which he called the Superman Saga. Crucially, Gunn insisted that each piece of that larger story should still work on its own, without requiring viewers to have watched everything else.

For casual fans, that promise is important. Superhero fatigue is often less about too many films and more about homework: the feeling that you cannot enjoy one story unless you have seen five others first. Gunn is trying to avoid that trap by making accessibility a creative rule, not an afterthought. You can watch a standalone film for its own genre pleasures, or follow the Superman Saga for the bigger arc, and neither experience should punish you for skipping the other.

Batman, Wonder Woman and Man of Tomorrow

What the James Gunn DCU diamond characters plan has not yet answered is the Batman and Wonder Woman question. Neither hero has a confirmed DCU film in production, and casting news has been quiet. Gunn’s recent comments suggest they are being held back deliberately, so that their eventual introductions land with real weight — the way Superman’s did, rather than as background detail in someone else’s movie.

What is confirmed is the next major test of the James Gunn DCU diamond characters plan: Man of Tomorrow, scheduled for July 9, 2027, continuing the Superman story that began in 2025. If Gunn’s framing is right, that film should function as both a satisfying Superman sequel and the first true event film of the new universe — a story that rewards longtime fans without shutting out newcomers.

In the end, the James Gunn DCU diamond characters plan is honest about value and effort. Diamonds have to be cut, polished and set in the right story. Superman is already shining. Batman and Wonder Woman are waiting for their moment. And if Gunn is right about Krypto, John Stewart and Peacemaker, the most exciting part of the DCU may be the heroes we are about to discover.
