The popular NCIS franchise is massive, and it shares its expansive universe with several iconic TV shows. Here’s how they all fit together.
The NCIS universe has blossomed over the last two decades, and some may be surprised to learn that the franchise shares that universe with other iconic TV shows. The franchise explores separate divisions of the Naval Criminal Investigation Service, and despite occasional formulaic elements in each series, they stand out by specializing in different types of cases. While their primary focus is on criminal cases involving the U.S. military, their specializations set them apart within the franchise’s procedural framework.
While the majority of TV shows in the NCIS universe revolve around criminal investigations, it’s remarkable that this procedural powerhouse originated from a courtroom drama. Equally surprising is the connection NCIS shares with a selection of iconic TV shows through the recently established Lankov-verse. With five titles currently bearing the NCIS tag and a sixth in development, it’s never been a better time to decipher how they all fit together.

JAG
JAG shares characters with First Monday and NCIS
JAG’s connection to NCIS is undeniable, as it kickstarted the franchise with its backdoor pilot episodes, “Ice Queen” and “Meltdown”, in season 8. Following an investigation into Lieutenant Singer’s murder, the episodes introduce several major NCIS characters, including Jethro Gibbs, Anthony DiNozzo, Vivian Blackadder, Abby Sciuto, and Donald “Ducky” Mallard. Since then, multiple JAG characters have made guest appearances in NCIS, such as Bud Roberts, Michael Rainer, and Catherine Bell, with A.J. Chegwidden recurring in both NCIS and NCIS: Los Angeles. In addition, JAG shares a connection with another legal drama, First Monday, thanks to U.S. Senator Edward Sheffield’s recurring appearances on both TV shows.

First Monday
First Monday shares characters with JAG
Although the series was shortlived, First Monday is notable for sharing the same universe as JAG, thanks to the overlapping character, Edward Sheffield. The legal drama centers on political and civil rights cases presented before the Supreme Court, the highest court in the United States. Sheffield initially made appearances in three episodes of First Monday where he plotted to get the main character, Joseph Novelli, impeached. Following the show’s cancelation, Sheffield became a recurring character in JAG beginning in season 8. There he briefly resumed his role as a U.S. Senator before eventually becoming the Secretary of the Navy.

Hawaii Five-0 has enjoyed multiple crossover events with NCIS: Los Angeles, Magnum, P.I., and MacGyver. Similar to the original series, the reboot focuses on an elite team of criminal investigators and enforcers who iconically answer to one person: Hawaii’s governor. The “Touch of Death” crossover event forces the Five-0 team to bring in the NCIS: Los Angeles team while investigating the Comescu crime family. In “Flashlight”, a massive earthquake sees MacGyver working with the Five-0 team to pursue Chinese intelligence after top-secret weapons go missing in Hawaii. Lastly, “Desperate Measures” sees the Five-0 team working with Magnum after a list of undercover CIA agents is stolen.

Scorpion
Scorpion shares characters with NCIS: Los Angeles
Scorpion joined the NCIS universe thanks to its crossover event with the NCIS: Los Angeles team. The series centers on the titular Scorpion team, an elite group that serves as the last line of defense against threats on a global scale. Similar to other shows of its type, the Scorpion team consists of members with diverse skills, from psychology to coding, to engineering. In the crossover episode, “True Colors”, Scorpion is accused of stealing a valuable painting, encouraging Cabe Gallo to enlist aid from NCIS: Los Angeles’ operations manager, Hetty Lange. NCIS: Los Angeles helps the Scorpion team recover the painting and lay any accusations against them to rest.

NCIS: New Orleans
NCIS: New Orleans shares characters with NCIS
In the two-part episode “Crescent City” during NCIS Season 11, the NCIS team collaborates with their counterparts from the New Orleans office to probe the mysterious death of a congressman. The investigation leads to the realization that both teams have been misdirected by an unknown party, and the second part of the backdoor pilot sees the combined NCIS teams engaged in a cat-and-mouse game with the real culprit. While the spin-off has yet to extend its narrative threads beyond the franchise, it has successfully engaged in multiple crossover events with the original series. These events feature notable guest appearances by characters who seamlessly traverse between both shows.

MacGyver
The rebooted MacGyver shares characters with Hawaii Five-0
MacGyver is one of three shows comprising Peter Lenkov’s “Lenkov-verse”, along with the similarly rebooted Magnum, P.I., and Hawaii Five-0. As a result, they share the same universe and, by extension, with the NCIS universe as a whole. The series follows Angus “Mac” MacGyver, whose hallmark intellect and resourcefulness find him improvising everyday objects (like candy bars) to circumvent a variety of global threats (like nuclear meltdowns) for his employer–a privately funded government intelligence agency. While the reboot didn’t survive long enough to crossover with multiple shows in the NCIS universe, it was able to connect with Hawaii Five-0 in the “Flashlight” crossover event.

Magnum, P.I.
The rebooted Magnum, P.I. shares characters with Hawaii Five-0
Magnum, P.I. is part of the same universe as NCIS through crossover episodes with Hawaii Five-0. The Lenkov-verse series reboot centers on ex-SEAL Thomas Magnum, who serves as a private investigator and security consultant. In the crossover episode, “Desperate Measures,” the Five-0 Task Force collaborates with Thomas Magnum in their joint investigation into a stolen list of undercover CIA agents. During their collective pursuit of the case, Junior Reigns’ kidnapping prompts Magnum and Juliet Higgins to unite with Tani Rey and Quinn Liu for a search-and-rescue mission, aiming to recover the crucial list and rescue Junior. Beyond the crossover, various supporting characters have made appearances in both shows.

NCIS: Sydney
NCIS: Sydney features several Easter eggs from the original series
NCIS: Sydney is the newest installment to the franchise, and while it has not yet featured any crossover episodes, it is set within the NCIS universe. Like its fellow NCIS TV shows, it follows a team of special agents of the Naval Criminal Investigation Service based in Sydney, Australia. The NCIS: Sydney team is led by Agent-in-Charge, Michelle Mackey, and sees the NCIS team work in tandem with the Australian Federal Police to solve criminal investigations. Although the series is extremely new, its creator, Morgan O’Neill, has assured that several Easter eggs will be in evidence as NCIS: Sydney continues. There will be plenty of opportunities for crossovers as the series matures.

NCIS: Origins
NCIS: Origins will feature Mark Harmon as its narrator
NCIS: Origins will mark the sixth installment in the NCIS franchise, serving as a prequel to the flagship series. Focusing on Leroy Jethro Gibbs’ early years with NCIS at Camp Pendleton, the narrative will unfold alongside agent Mike Franks. Although Mark Harmon is not anticipated to make a physical return, he will lend his voice as the series’ narrator. Although NCIS: Origins will feature another character from the original show, it is unlikely to showcase many characters from the franchise since it will be set in the 1990s. With an emphasis on Gibbs’ formative experiences, NCIS: Origins will offer a unique exploration of the character’s early career within the broader context of the expanding NCIS franchise.
