Karen Gillan, the actress behind Nebula in the Marvel Cinematic Universe (MCU), recently shared insights into the character’s future following the conclusion of the Guardians of the Galaxy trilogy. Speaking in an interview published on June 8, 2025, the Scottish star expressed enthusiasm for her time in the MCU but remained cryptic about returning to the role that defined much of her career. Nebula, introduced as Thanos’ adopted daughter in 2014, evolved over nearly a decade into a fan-favorite through a compelling redemption arc. Her absence from the cast list of Avengers: Doomsday and the new Guardians team led by Rocket Raccoon has sparked questions about her next steps. What drives this uncertainty? How might Marvel weave beloved characters into its evolving narrative? Gillan’s comments have reignited fans’ curiosity about Nebula’s fate.
The interview, conducted during a promotional event, offered a mix of excitement and restraint. “It’s so much fun working in the Marvel world… as for the future, I can’t say anything. You know how it goes, but maybe… never say never,” Gillan stated. Her response aligns with Marvel’s tight-lipped approach, often keeping surprises under wraps until the last moment. For fans, the prospect of seeing Nebula again is thrilling, especially after her emotional arc in Guardians of the Galaxy Vol. 3 (2023), where she found a new family and rediscovered joy after years of trauma.
Nebula’s journey in the MCU is rich with complexity. Debuting as a loyal enforcer for Thanos in Guardians of the Galaxy, she transformed into a central figure, shining in Avengers: Endgame (2019) and the Guardians of the Galaxy Holiday Special (2022). Key milestones in her arc include:
- Reconciling with her adoptive sister, Gamora, after years of rivalry.
- Playing a pivotal role in defeating Thanos, showcasing her courage.
- Joining the Guardians and taking a leadership role in Guardians of the Galaxy Vol. 3.
- Displaying vulnerability, like her awkward dance in the holiday special, which endeared her to audiences.
This evolution has cemented Nebula as a beloved character, fueling anticipation for her potential return. Yet, the lack of official announcements keeps fans guessing.
Why is Nebula’s future uncertain?
Several factors contribute to the ambiguity surrounding Nebula’s MCU prospects. Guardians of the Galaxy Vol. 3, directed by James Gunn, provided a satisfying conclusion for many characters, with Nebula settling into a leadership role in Knowhere. This closure makes it challenging to craft new stories without undermining her arc. Additionally, Marvel is transitioning to Phase 6, focusing on projects like Avengers: Doomsday (set for 2026) and Avengers: Secret Wars (2027), which prioritize new villains like Doctor Doom and a refreshed cast.
Karen Gillan’s busy schedule also plays a role. Known for roles in Doctor Who and Jumanji, the actress has been tackling diverse projects, from indie films to stage productions. Her availability for an MCU return may hinge on contract negotiations and Marvel’s plans for Nebula. Still, Gillan has previously expressed fondness for the character, even pitching ideas like a rom-com featuring Nebula or a prequel exploring her backstory.
Marvel’s strategy for legacy characters
Marvel faces the task of balancing established characters with fresh faces. After Avengers: Endgame, Phases 4 and 5 introduced heroes like Shang-Chi and the Eternals but faced criticism for narrative disconnect. Upcoming films like Thunderbolts (2025) and Avengers: Doomsday suggest a return to interconnected storytelling, potentially featuring familiar figures. While Nebula isn’t confirmed for these projects, Marvel’s secrecy leaves room for surprises. The full cast for Avengers: Doomsday remains undisclosed, fueling speculation.
Nebula’s popularity is a strong argument for her return. James Gunn, former Guardians director and now co-CEO of DC Studios, once noted the unexpected fan love for Nebula and Groot, which prompted Marvel to expand their roles. This fanbase could influence decisions to bring her back, even in a limited capacity like a cameo.
Potential paths for Nebula’s return
Should Nebula reappear, Marvel has multiple avenues to explore. A prequel, as Gillan suggested in 2023, could delve into her life under Thanos’ control, ideal for a Disney+ series or special. Alternatively, Avengers: Secret Wars, with its multiversal scope, could feature Nebula alongside other cosmic heroes. The comic-inspired storyline offers a chance for her to contribute to a grand narrative.
Marvel’s animated ventures, like What If…?, present another option. A Nebula-centric episode—perhaps showing her leading the Guardians or defeating Thanos solo—could resonate with fans while preserving her live-action arc. These possibilities allow Marvel to leverage Nebula’s appeal without disrupting her Guardians conclusion.
Karen Gillan’s star power
Karen Gillan’s talent elevates Nebula’s allure. At 37, the actress has built a diverse career, from her breakout role as Amy Pond in Doctor Who to action-comedy in Jumanji: Welcome to the Jungle. Her ability to blend intensity and vulnerability has made Nebula a standout. Gillan has often spoken of her gratitude for the role, noting how it pushed her to explore complex emotions.
Her connection with fans further boosts her value. Active on social media, Gillan engages with audiences, sharing behind-the-scenes glimpses and answering MCU queries. This rapport heightens anticipation for Nebula’s potential return, as fans see her as deeply invested in the character.
Marvel’s culture of secrecy
Gillan’s vague comments reflect Marvel’s secretive ethos. Under Kevin Feige’s leadership, the studio is notorious for withholding details, with actors bound by strict non-disclosure agreements. High-profile surprises, like Andrew Garfield’s return in Spider-Man: No Way Home (2021), prove Marvel’s knack for secrecy. Gillan’s “never say never” stance thus leaves open the possibility of an unannounced role.
This secrecy also keeps audiences engaged. Gradual reveals and cryptic teasers sustain excitement, especially as Marvel aims to rebound from mixed reactions to recent projects like Thunderbolts, which underperformed at the box office. Nebula’s return could be a strategic move to rekindle fan enthusiasm.
Fan expectations for Nebula
Nebula’s fanbase is active online, frequently debating her future. Many argue she deserves more spotlight, whether in a solo project or a larger ensemble. Her arc from villain to hero resonates for its themes of resilience, with moments like her dance in the holiday special or leadership in Knowhere highlighting her depth.
Fans have voiced specific hopes:
- A project exploring Nebula and Gamora’s reconciled bond.
- A role in Avengers: Secret Wars alongside cosmic heroes.
- A What If…? episode showcasing a fresh angle on Nebula.
- Integration into new teams, like the Thunderbolts or a revamped Guardians lineup.
These desires underscore Nebula’s lasting impact and the demand for her return.
Challenges of bringing back legacy characters
Reintroducing characters like Nebula requires finesse. Marvel must avoid retcons that feel forced or diminish completed arcs. Guardians of the Galaxy Vol. 3 succeeded partly due to its satisfying resolutions, and reopening Nebula’s story demands a strong narrative rationale. Phase 6’s multiversal focus may also limit space for cosmic characters in Earth-centric plots.
Budget constraints are another hurdle. MCU projects carry hefty price tags, and Marvel has grown cautious after recent box-office setbacks. Including Nebula in a crowded ensemble like Avengers: Doomsday would require a meaningful role to justify the cost. Smaller appearances, like cameos, might be a more feasible way to satisfy fans.
Nebula’s enduring legacy
Whether or not she returns, Nebula has left an indelible mark on the MCU. Her journey from Thanos’ outcast to Knowhere’s leader is among the franchise’s most compelling arcs. Karen Gillan’s nuanced performance, blending grit and heart, has elevated Nebula beyond a supporting role.
Gillan’s recent remarks keep hope alive for new chapters. Whether through a cameo, a standalone story, or a role in Avengers: Secret Wars, Nebula’s potential remains vast. For now, fans eagerly await any hint of her next move as Marvel continues its secretive planning.
