If the rumor is true I'm not expecting anything more than just your usual standard MCU cameo chances are we'll just see a black a woman with white hair flash across the screen as Gorr delivers villainous monologue or more than likely a post credit scene of storm doing some weather shit in Kenya.
And considering Monica Rambeau already debuted in a Wanda and vision TV show the MCU have already established that they can do whatever the hell they want with these characters lol
