We’re eagerly anticipating the next Avengers films coming out in 2018 and 2019, the two-part epic Avengers: Infinity War. The team’s roster will most likely include these popular heroes: Captain America, Iron Man, and the other veterans, plus newbies like Black Panther, Captain Marvel and Spider-Man. But what about beyond the third Avengers film? Will we have the same lineup or will new blood take the place of the old guard? Given how bloated Avengers: Age of Ultron felt with nine heroes, it’s unlikely future Avengers films will have large casts. So who would be interesting candidates to fill the ranks of Earth’s Mightiest Heroes as the veterans exit the stage? These are some suggestions:

Ares: The Greek god of war was a member of the Dark Avengers, so he comes with the anti-hero baggage. So, he can be a dark, more badass version of Thor as he uses traditional weapons like swords and axes with modern weapons like guns.

Black Knight: Inspired by Arthurian legend, Dane Whitman wields a magic sword and shield and rides a winged horse. The catch is that the sword that can cut through anything has a blood curse. This all may be too magical for the science-based Marvel Cinematic Universe (MCU), but if there’s room for Doctor Strange then the MCU can make allowances for the Black Knight.

Giant-Man and the Wasp: He’s actually Hank Pym, the original Ant-Man, who decided to use his shrinking power in reverse. And of course, comic book fans know that the Wasp was his wife and at one point, supposed to have been in The Avengers, as seen by some storyboards. The characters will obviously be different people in the MCU given the character situation with Ant-Man.

Hercules: Think of a more fun version of Thor and you got Hercules! Imagine his romps as he battles and brags his way across the silver screen. Plus, his fanciful boasts and love of revelry and fighting would provide light-hearted relief as if an Avengers film could use it. Another angle is to use him and Ares or Thor as foils against one another.

Quasar: Marvel’s answer to Green Lantern would add a cosmic angle to the Avengers’ roster. Armed with Quantum Bands fused to his wrists, these objects allow Wendell Vaughn to tap and use energy to fight evildoers. Not only that but his cosmic-based background could conceivably link the Avengers to the larger galaxy without resorting to Thanos.

She-Hulk: Come on, we all want to see how Marvel Studios pulls this off! BTW, CG isn’t needed to bring the beautiful cousin of the Hulk to life on screen. She would make for some inspired eye candy and an excellent counterpoint to the brutish Hulk.

Spectrum: At one time called Captain Marvel, Monica Rambeau has energy-based powers and was one of the most versatile and powerful members of the superhero team. She even led the team at one point and the spectacle of her turning into different kinds of energy would look fantastic on film.

Spider-Woman: Hey Marvel and Sony made nice and are now sharing Spider-Man. That should embolden Marvel Studios enough to go ahead and give us Spider-Woman. Besides with her Hydra/S.H.I.E.L.D. backstory it should be cinch to throw her into the Avengers.

Tigra: Originally Greer Grant was the superhero called The Cat but was later transformed through mystical means into Tigra with tiger-like powers. It’s easy to conceive of a sexy but tough leading lady playing this role. As with other candidates some tweaking is needed to change the mystical angle.

Wonder Man: One of the earliest and most powerful members of the Avengers deserves his shot at the big screen. Simon Williams’ tragic story of a pawn used to betray the Avengers and his eventual redemption is a great story that can be used in a future Avengers film.
