Top 10 Arrowverse Crossover Episodes

DC may be struggling to get together on the big screen, but its small screen heroes have had some great team ups. Welcome to WatchMojo.com and today we’re counting down our picks for the Top 10 Arrowverse Crossover Episodes. For this list, we’re looking at the best occasions when CW superhero shows have featured elements from other shows set in the Arrowverse, whether they’re character cameos or full blown episodes devoted to interconnection. #10: “Duet” “The Flash” (2014-) One of the most imaginative crossovers in the Arrowverse, “Duet” sees Kara, a.k.a. Supergirl, reunite with Barry “The Flash” Allen when they’re trapped inside a musical world by the mischievous Music Meister. To get out, the pair must follow the plot of the musical they’re a part of. A loving tribute to the classics of the genre, “Duet” features a stylish ‘40s aesthetic, beautifully performed songs and dances, and a thrilling fight scene in the real world involving the duo’s friends and the Music Meister. Bottom line – this is a team up for the ages. #9: “Legends of Today” & “Legends of Yesterday” “The Flash” (2014-) & “Arrow” (2012-) This two-parter sees Teams Flash and Arrow team up when they encounter the immortal Vandal Savage, who is in pursuit of a pair of winged, reincarnated lovers and a powerful staff. The two superheroes and their respective entourages work together very well, leading to some great team up fight scenes, and even some time spent letting their hair down. The most important aspects of this crossover, however, are the introduction of Savage and the Hawks, which, along with the episode titles and the presence of time travel in part two, helped set up the spin-off series “Legends of Tomorrow.” #8: The Show Itself “Legends of Tomorrow” (2016-) The entire concept of “Legends of Tomorrow” is one big crossover, bringing together secondary characters originally from “Arrow” and “The Flash” to save history and the world. The Waverider crew is comprised of a diverse bunch, including scientists, thieves, and assassins, and their interactions with each other and eventual bonds are well executed. While the show’s approach to time travel is rather cavalier, it does allow for some hilarious interactions with historical figures, adding to the general sense of fun that makes “Legends of Tomorrow” a blast to watch and distinct from its parent shows. #7: “Haunted” “Arrow” (2012-) This episode sees Oliver Queen call on a certain mystical detective for help – John Constantine. Yup, this crossover retroactively included the show “Constantine,” which had aired on NBC, into the Arrowverse’s continuity. Constantine is integral to both the show’s usual island flashbacks, as well as the current storyline, where he helps restore Sara Lance’s soul. His presence also helps drive home the introduction of magic to the Arrowverse. It’s a fairly strong episode overall with some good character development and interactions between the regulars. But it’s Constantine’s appearance that’s the very exciting cherry on top. #6: “Taken” “Arrow” (2012-) One of the more obscure parts of the Arrowverse is the animated web series “Vixen,” which follows the namesake heroine’s adventures in Detroit, during the course of which she encounters the Flash and the Green Arrow. Although the series is excellent, ultimately we had to go with the character’s first live-action appearance in which she assists Oliver in rescuing his son from the villain Damien Darhk. Seeing Vixen’s animal-based magical powers realized on TV is a treat, and the episode itself offers some excellent character work and musings on fatherhood, while also advancing the plot, since Vixen destroys the artifact giving Darhk his powers. #5: “Paradox” “The Flash (2014-) After creating “Flashpoint,” Barry attempts to hit the reset switch and make things right. He quickly realizes, though, that he’s forever altered history, affecting the lives of his friends and loved ones. Ultimately, he turns to Felicity for help, which acts as the episode’s framing device. However, his search for reassurance also leads him to discover his actions have had consequences more far-reaching than he suspected, since Diggle, a member of Team Arrow, now has a son, instead of a daughter, setting up some conflict that may play out in another entry on our list. #4: “All Star Team Up” “The Flash” (2014-) This light-hearted episode features guest appearances from Ray Palmer and Felicity, both originally from “Arrow,” though Ray would later become a regular on “Legends of Tomorrow.” The pair seeks out help with Ray’s ATOM suit, which they also use to help defeat the villain-of-the-week, a woman who controls a swarm of robot bees. The adorkable duo fit right in with Team Flash’s atmosphere, and their hilariously awkward dinner date is a definite highlight. While it may not have the scale or importance of some of our other entries, “All Star Team Up” is a star in our books. #3: “Flash vs. Arrow” & “The Brave and the Bold” “The Flash” (2014-) & “Arrow” (2012-) The first major crossover event for the Arrowverse, this two-parter is still one of the best. In the first half, Team Arrow makes an appearance on “The Flash” and helps deal with a metahuman who causes rage in other people, while the second part sees Team Flash appear on “Arrow” to assist in taking down Captain Boomerang. And the two heroes play off each other brilliantly. The first part is particularly significant, as Barry benefits from Oliver’s experience and Oliver learns from Barry how to inspire others. The supporting casts also shine here, and help make these episodes a solid foundation for future crossovers. #2: “Worlds Finest” “Supergirl” (2015-) Barry’s experimentation with going faster sends him to a parallel universe where he immediately runs into Kara Danvers, a.k.a. Supergirl. The two quickly hit it off, and it’s a good thing too, since a pair of super-powered criminals is on the loose. Our heroes have plenty of charm and their chemistry with each other is off the charts, leading to some great comedy. Add in some creative and fun fight scenes, and you’ve got a recipe for one of the Arrowverse’s breeziest and most delightful crossovers. Before we get to our top pick, here are a few honorable mentions: - “Out of Time” “Legends of Tomorrow” (2016-) - “The Scientist” “Arrow” (2012-) - “Pilot” “The Flash” (2014-) #1: “Invasion!” “Supergirl” (2015-), “The Flash” (2014-), “Arrow” (2012-) & “Legends of Tomorrow” (2016-) When an alien invasion threatens Earth, the Arrowverse’s finest must join forces in an ambitious crossover event. Each episode adds its own flavor to the mix, while carrying the story and character arcs forward: after a hint of things to come at the end of “Supergirl”’s “Medusa” episode, “The Flash” has a CG-heavy fight scene and deals with the fallout of Flashpoint, “Arrow” celebrates its 100th episode by showing its cast “what could’ve been” while imprisoned by the aliens, and “Legends of Tomorrow” adds a time travel element. Supergirl even drops in to bring the awesome levels up to eleven. With the story’s scale, great interactions among the casts, and Easter eggs like the Hall of Justice, this is one crossover that’ll be tough to beat.
