The Big Return – Mark Harmon Is Back as Gibbs
In a surprise twist that’s lighting up the NCIS fan base, Mark Harmon, the original special agent Leroy Jethro Gibbs, is returning to the NCIS universe. After stepping away in 2021, he’s set to appear again in a crossover event on NCIS and NCIS: Origins this November. His comeback is being billed not as a mere cameo — there’s more to it, both narratively and emotionally.
Why This Return Matters: More Than Just Nostalgia
-
Returning for the first time in four years, Harmon’s participation is a big deal for longtime fans.
-
He’s not just acting: he continues his role behind the scenes as executive producer and narrator for NCIS: Origins.
-
Showrunners David J. North and Gina Lucita Monreal teased that Gibbs “is no longer alone,” hinting at deeper character exploration.
A Bit of Backstory – Gibbs’ Exit in 2021
-
Gibbs’ departure was framed as a peaceful retreat: he disappeared to Alaska to live in solitude.
-
The exit came after 18 seasons of Harmon anchoring the NCIS flagship until 2021.
-
Though he left as an actor, he never fully severed ties — his behind-the-scenes involvement stayed strong.
The Crossover Event – What to Expect
-
The return happens during a Veterans Day special: back-to-back episodes between NCIS and NCIS: Origins airing Nov 11, 2025.
-
In the Origins episode, Austin Stowell plays a younger Gibbs working on a case in the 1990s, which also reverberates into the present-day NCIS.
-
This storyline nicely bridges Gibbs’ past and future — giving longtime viewers something more meaningful than a quick throwback.

He praised the storytelling, saying David and Gina “continue to push boundaries” and dig into the character’s backstory.

For him, this isn’t just fan service — it’s a chance for real character development.
What This Means for the Franchise

Gibbs is arguably the most iconic character in the entire NCIS universe, and his return signals that the franchise still values its roots.
-
With NCIS expanding — including NCIS: Origins and NCIS: Sydney — bringing Gibbs back adds weight and continuity.
-
Harmon’s presence can boost viewership, especially among longtime fans who grew up watching him on the original.
Emotional Resonance — Why Fans Are Hyped
-
Gibbs isn’t just a character; he’s a symbol of leadership, ritual, and moral compass.
-
His return is likely to spark nostalgia, but also allows for new emotional beats — reconnecting with old relationships, facing unresolved conflicts, or simply reflecting on his legacy.
-
Many viewers see this as a “reward” for sticking with the show, a payoff for years of loyalty.
Behind the Scenes: Harmon’s Evolution
-
After 18 years in front of the camera, Harmon stepped away as a regular, but never left the NCIS creative team.
-
As executive producer on NCIS: Origins, he’s helped shape the prequel’s direction, giving him a powerful voice in how Gibbs’ early career is portrayed.
-
His dual role — on-screen and off — suggests this is more than a cameo. It’s a meaningful extension of his legacy.
The Broader NCIS-verse Strategy
-
NCIS: Origins isn’t just a spin-off; it’s a world-building tool that’s strengthening the entire NCIS-verse.
-
This crossover could set a precedent for future returns: more legacy characters might come back in similar ways.
-
By blending past, present, and future stories, the franchise keeps long-time fans engaged while growing its narrative universe.
Potential Risks — And Why They’re Worth It
-
Risk: Fans might perceive the return as gimmicky or “fan service.” But the creative team seems deeply invested, not just playing to nostalgia.
-
Risk: Overdoing Gibbs could overshadow newer characters. But if handled wisely, his return can elevate the ensemble rather than dominate it.
-
But the reward is big: re-establishing Gibbs as a guiding presence, reconnecting emotionally with fans, and delivering a story that feels earned.
How This Return Reflects TV Trends

Legacy characters coming back is a growing trend in TV — think of how many shows now do reunion episodes or legacy crossovers.

For NCIS, it’s not just a ratings move. It’s a way to honor the past while investing in the future.

Harmon’s return feels authentic — not just cashing in, but contributing to the bigger NCIS story in a lasting way.

-
Some are hoping for meaningful interactions: old teammates, unfinished business, or more insight into what Gibbs has been doing in Alaska.
-
Others are cautiously optimistic: they want this to be more than a cheap nostalgia trip, but something that enriches Gibbs as a character.
Impact on Ratings and Legacy
-
Expect a bump in ratings: special events like crossovers often draw in lapsed viewers and loyal fans alike.
-
Harmon’s presence could also draw media attention, spotlighting NCIS as not just a procedural, but a legacy franchise.
-
For the long run, this strengthens the NCIS narrative backbone: Gibbs is still central, still meaningful.
What’s Next — Looking Forward

Spin-offs may lean further into legacy characters, using crossover events as anchor points.
-
We might see more prequel-style storytelling, digging into other agents’ pasts, using Gibbs as a connective tissue.
-
The franchise could adopt a “shared universe” strategy more aggressively — think MCU, but for naval crime drama.
Why This Return Resonates Personally
-
For fans who grew up watching Gibbs lead the team, his return feels deeply personal — a reunion with a character who felt like a mentor.
-
For newer viewers, it’s a chance to understand Gibbs’ full arc — not just as who he was, but where he came from and where he might be headed.
