Marvel Studios may be rebooting the MCU following the release of Avengers: Secret Wars, meaning several previous MCU characters could be reinvented for new actors. Since Marvel Studios kicked off the MCU with 2008's Iron Man, dozens of powerful superheroes and dangerous villains have been adapted into live-action, delivering some of their most iconic storylines from Marvel Comics to massive audiences. While this has helped to create the most expansive and successful movie franchise of all time, introducing so many characters also comes with its flaws, as many have been neglected or killed off, despite having more stories to tell.
