The "She-Hulk" trailers also tease another appearance for Charlie Cox's "Daredevil."
Cox originally played the character in Netflix's "Daredevil" and "The Defenders" series, which had ties to the MCU but were never confirmed as being canon.
In the series, Matt Murdoch (Cox) is a lawyer who was blinded by radioactive waste. The waste actually heightened his other senses, prompting him to use his abilities to fight criminals he is unable to stop in his day job. This puts him up against several criminal empires including one run by New York crime boss Kingpin (Vincent D'Onofrio).
In the "Defenders" series, Daredevil works with a group of New York street heroes to stop the Hand, an organization of mystical ninjas, from resurrecting dragons underneath the city. Daredevil sacrifices his life to save the day but he is later revealed to be alive.
Last year, both Cox and D'Onofrio reprised their roles in MCU projects. Cox was Peter Parker's lawyer in "Spider-Man: No Way Home" when he was accused of killing Quentin Beck.
It is still unclear whether the characters are the same as they were in the Netflix series, however, Cox's upcoming appearance in "She-Hulk" could clear things up.
