Whoever will play Robin must be able to shine alongside Batgirl's ideal Robin would be Dick Grayson, as the two have a long and complicated dynamic throughout the DC comics and other related media. Apart from being the first hero to take on the mantle of Robin, Grayson also had a long-term, romantic, and off-again-on-again relationship with Batgirl, and exploring this blurring of lines between lovers and superhero colleagues could allow the DCEU to set up more relatable and complex stories down the line.

Michael Keaton's Robin in Batgirl needs to be an actor with both physical and emotional range. Whether Batgirl's Robin ends up being Dick Grayson, Jason Todd, Tim Drake, or even Damian Wayne, fleshing out the character will be no easy feat. Here are some very talented actors who might be able to pull off being the DCEU's new Boy Wonder.

Ludi Lin

Chinese-Canadian actor Ludi Lin is better known as Liu Kang from the live-action Aquaman, shows that he could have the skills necessary for Robin's acrobatic athleticism. Lin's not a bad actor, either, which could be owed to his extensive education in the performing arts, including a stint in the theater program at the University of British Columbia. Moreover, as a well-rounded actor who's fluent in multiple languages and dialects, Lin could conceivably bring the intelligence expected of Batman's right-hand hero.

Joshua Bassett

Joshua Bassett is mainly famous for playing Ricky Bowen in The Flash could reboot the DCEU, a theory that's ed by the return of Michael Keaton as Batman, Bassett might just be the right age for playing Dick Grayson in Batgirl. The story of Robin could also be fleshed out both in real-time and in flashbacks, which would necessitate someone who can conceivably play a teenage Robin. Moreover, there are also rumors that Joshua Bassett has already been cast for the role of Robin in Batgirl. Whether or not these rumors are true, Bassett might just have what it takes to be the Boy Wonder of the post-Flash new Earth in which Batgirl is set.

Dylan O'Brien

Another actor rumored to be playing the new Robin is Dylan O'Brien. The talented young veteran is well-known for his starring role in the teen sci-fi drama Maze Runner, as well as his lead role in the The Outfit. O'Brien's acting career is nothing short of impressive, and he might be the veteran that's needed for truly doing justice to Robin's dramatic complexity. Much like Ludi Lin, what O'Brien brings to the table could also set the stage for the DCEU to finally introduce Nightwing. Moreover, O'Brien would definitely do well as the love interest of Leslie Grace's Barbara Gordon.

Mena Massoud

Egyptian-born Canadian actor and singer Mena Massoud is a rising star who appears in several notable drama series such as Open Heart, Tom Clancy's Jack Ryan, and live-action remake of the classic Disney movie. In his role as Aladdin, Massoud exhibited both acting chops and a talent for acrobatic action. This is likely why Massoud, alongside many of the other actors on this list, is rumored to be already cast as the Boy Wonder. As a rising star who's been making a name for himself in the drama, sci-fi, and fantasy genres in recent years, Mena Massoud would indeed be a great addition to the current and next phases of the DCEU.

Timothée Chalamet

Not only could Chalamet inhabit the role of Dick Grayson – either as Robin or Nightwing – he would also be perfect for the roles of either Jason Todd or Tim Drake. As the star of films such as Don't Look Up, in which he stole the show in the third act of the movie despite having just a small role. Moreover, after the DCEU just let go of several A-listers, pulling Chalamet into the fold would be a very wise marketing decision for the studio, as Robin's introduction in Batgirl, coupled with the Flash DCEU reboot theory, could potentially result in a long-term role for the character within the DCEU.
