Doctor Strange in the Multiverse of Madness is arriving in theaters on May 5. Audiences will come across a new character ‘America Chavez’, the Marvel comic book character, played by young actor Xochitl Gomez. Her addition has already received a lot of praise, with her inclusion seen as a win for representation, as she is the rare Latina superhero in the Marvel Cinematic Universe.

For comic book writer Joe Casey, seeing Chavez soar to new heights is bittersweet. Casey is proud of his work on America Chavez and what she represents. Yet, like many comic book writers before him, Casey feels a tinge of regret watching his creation take off without him being meaningfully compensated for it. Casey has not received payment for America Chavez, outside of the page rates he got when working for Marvel as a writer, when he and artist Nick Dragotta introduced the character in 2011.
