Hawkeye, Black Widow, Captain America — there are a LOT of Marvel superheroes (and super villains!) out there. But some heroes, the movies/shows they were featured in, and the actors who portrayed them just got special recognition.
In the film Eternals, Marvel introduced a superhero who is deaf, Makkari, to the Marvel Cinematic Universe. In the Disney+ series Hawkeye, Marvel introduced another super-powered character who is deaf, Echo. Both roles were portrayed by deaf actors. Now the company is being recognized for featuring actors with disabilities.
