FBI: International—the globe-trotting iteration of the popular franchise—kicks off Tuesday, Sept. 21, as part of a three-hour crossover premiere event! So you'll get introduced to the Fly Team's special agents with a little help from some friends, including FBI's OA (Zeeko Zaki) and Maggie Bell (Missy Peregrym) and FBI: Most Wanted's Jess LaCroix (Julian McMahon).
Of course, this isn't the first time we've seen our favorite characters from different shows cross paths. Watch rounds up some of our favorite crossover events!
The FBI three-hour crossover event airs Tuesday, Sept. 21, 8-11 p.m. ET/PT on CBS.

Kara (Melissa Benoist) and Barry (Grant Gustin) find themselves trapped in a musical and must sing and dance their way out of this alternate reality. Luckily for them (and us viewers), this dynamic duo is more than capable of tackling the demanding song-and-dance numbers. Their fellow Glee alum Darren Criss plays the crossover's big bad, the Music Meister.

Agents Sam Hanna (LL COOL J) and G. Callen (Chris O'Donnell) head to the Aloha State to help Five-0 nab prime suspect Dracul Comescu. The joint task force—with Detective Sergeant Danny Williams (Scott Caan) and Lieutenant Chin Ho Kelly (Daniel Dae Kim), in tow—travels from Hawaii to Los Angeles when the lead suspect in the case moves to the mainland with a deadly virus. Fun fact: "Pa Make Loa" in Hawaiian translates to "Touch of Death."
NCIS and NCIS: New Orleans "Pandora's Box Parts I and II"

Laissez les bons temps rouler ("let the good times roll") when the NCIS and NCIS: New Orleans teams join forces to track down a "how to be a terrorist" playbook—during Mardi Gras, no less, where everyone is masked!

The CW's annual Arrowverse crossover—which unites all of the network's DC shows—is always an event. But the "Crisis on Infinite Earths" storyline, where our super friends unite to vanquish the Anti-Monitor—more than lived up to the hype, with long-lasting repercussions, fun cameos from other DC properties (hello, Man of Steel Brandon Routh and Ezra Miller Flash), and one shocking death (RIP Oliver Queen/Green Arrow).
Hawaii Five-0 "Ihea 'oe i ka wa a ka ua e loku ana?" and Magnum, P.I. "Desperate Measures"

Sure, Hawaii Five-0 characters have appeared on Magnum, P.I. before, but in this full-fledged crossover, McGarrett (Alex O'Loughlin) and co. reluctantly team up with Magnum (Jay Hernandez) and Higgins (Perdita Weeks) to recover a stolen list of undercover CIA agents.
The Winchester Bros. get animated for "Scoobynatural."

On paper, the tonally different cartoon classic and the totally-not-for-kids Supernatural series shouldn't work—and yet the meta "Scoobynatural" episode hits you with the nostalgic feels. Sam (Jared Padelicki), Dean (Jensen Ackles), and Castiel (Misha Collins) are sucked into the 1970 Scooby-Doo, Where Are You! episode "A Night of Fright Is No Delight" and must help the Scooby Gang solve the mystery. Of course Dean (being Dean) calls "dibs on Daphne!"
