Every Major TV Reveal from San Diego Comic-Con 2025: Peacemaker, Gen V, Star Trek & More
San Diego Comic-Con 2025 delivered a stacked weekend for television fans, with major announcements, exclusive footage, and long-awaited updates from the most iconic franchises on air. So, without any further hesitation, here’s a breakdown of the biggest reveals, premieres, and surprises from SDCC 2025's television programming slate.
Peacemaker Season 2
HBO Max kicked off SDCC 2025 with a new trailer for Peacemaker Season 2 during a Hall H presentation, introducing a wild “pocket universe” storyline tied to recent developments in the DCU. The trailer features returning characters and a warped multiverse twist, along with stylistic nods to both James Gunn’s previous work and the irreverent tone fans have come to expect.
The second season, which premieres August 21, 2025, will continue following Peacemaker as he navigates the consequences of his violent “heroism.” With stylistic flair and increasingly bizarre scenarios, the show promises more high-energy action, meta-humor, and deeper emotional threads than its debut season.
Gen V Season 2
Prime Video premiered the first trailer for Gen V Season 2, confirming the show’s return to its blood-soaked superhero school with even tighter integration into The Boys universe. The new footage introduced darker themes, new supes, and deeper political and corporate ties that set the tone for an explosive second year.
Season 2 is currently scheduled to premiere on September 17, 2025. The crossover potential with The Boys appears to be a major draw this season, along with continuing character arcs for Marie, Emma, and Jordan, who are shown grappling with the consequences of power and surveillance in a superhuman world gone corporate.
The Boys Season 5
The Boys took center stage at SDCC with a teaser trailer for its fifth and final season. Fans were treated to glimpses of massive destruction, emotional showdowns, and several surprise appearances—most notably, Jared Padalecki and Misha Collins joining the cast. Seth Rogen also makes a meta cameo as himself, doubling down on the show’s self-aware streak.
While no release date was set, the season is expected in 2026 and promises to tie up major threads, including Homelander’s arc and the fractured future of Vought International. The panel confirmed that filming had wrapped earlier this summer, heightening anticipation for the show's final bloody act.
Percy Jackson and the Olympians Season 2
The Hall H crowd was treated to a preview of Percy Jackson and the Olympians Season 2, featuring the first look at Tyson, Percy’s Cyclops half-brother. The trailer teased epic sea voyages, mythical creatures, and expanding tensions between the gods—all drawn from the beloved book The Sea of Monsters.
The creative team also promised a more emotionally grounded arc as Percy begins to fully step into the hero role while wrestling with growing dangers and personal revelations. Season 2 will premiere on December 10, 2025, with returning cast members including Walker Scobell, Leah Sava Jeffries, and Aryan Simhadri.
NCIS: Tony & Ziva
Fans of the long-running NCIS franchise were rewarded with a full trailer for Tony & Ziva, the highly anticipated spinoff set in Paris. The show picks up with Tony DiNozzo and Ziva David in hiding after a cyber-attack forces them to flee with their daughter, Tali. Their peaceful life is upended as assassins, espionage, and unresolved feelings come to the forefront.
The 10-episode series will debut on September 4, 2025, with new episodes weekly. Cast members described the project as part espionage thriller, part family drama, and a long-overdue emotional payoff for fans who’ve waited over a decade to see Tony and Ziva reunited on screen.
Star Trek: Starfleet Academy
Paramount+ unveiled the first trailer for Starfleet Academy, introducing a new generation of cadets training in a futuristic San Francisco. Set in the 32nd century, the series includes a mix of legacy characters and fresh faces, with Holly Hunter leading the cast as Chancellor Nahla Ake and Paul Giamatti playing the central antagonist.
The show explores academic life and the ethical challenges facing young cadets during a moment of renewal for the Academy. With dramatic tension, sci-fi action, and a few well-placed easter eggs, Starfleet Academy promises to bridge the gap between Discovery and a new frontier for the franchise when it debuts in early 2026.
Star Trek: Strange New Worlds – Season 4 Tease
While not presenting a full trailer (since Season 3 just started airing), the Strange New Worlds panel offered a sneak peek at Season 4—including footage from a musical and muppet-themed episode. The creative team teased bold genre swings while reaffirming their commitment to episodic storytelling and character exploration.
Though a premiere date wasn’t locked in, Season 4 is expected to drop in 2026. The series continues to gain praise for its balance of classic Trek spirit and modern storytelling, and the SDCC tease confirmed that the show still isn’t afraid to take creative risks.
IT: Welcome to Derry
HBO previewed the first 10 minutes of IT: Welcome to Derry, setting a chilling tone for the upcoming prequel to Stephen King’s IT. Set in the 1960s, the series explores the origins of Pennywise and the long history of horror that has haunted the town of Derry. New characters are introduced, while the tone pays homage to both King’s mythology and the 2017 film adaptation.
The show is expected to premiere in October 2025, with a cast that includes Jovan Adepo, Taylour Paige, and James Remar. Bill Skarsgård returns as Pennywise, and early footage suggests a return to atmospheric terror and character-driven horror rather than spectacle alone.
Spartacus: House of Ashur
One of SDCC’s most buzzed-about legacy revivals came from Starz, which unveiled the first teaser for Spartacus: House of Ashur. The series sees the return of Nick E. Tarabay as the cunning and power-hungry Ashur, who survived the events of Spartacus: Vengeance and now seeks to rise amid the collapse of the Roman slave system.
Set in the power vacuum left by Spartacus’s rebellion, the series will explore betrayal, ambition, and shifting alliances. With the same visceral tone and raw intensity that defined the original, House of Ashur is slated to premiere in early 2026 and will mark a bloody new chapter in the Spartacus saga.
Final Thoughts
From franchise world-building (Percy Jackson, Star Trek, The Boys) to long-awaited returns (Tony & Ziva, Spartacus), this year’s convention lineup delivered high-stakes storytelling and emotional payoffs across every genre. And, as studios gear up for packed fall and winter release calendars, these reveals remind us that television’s golden age of fandom is still going strong.
